This review provides actionable insights for researchers, policymakers, and industry leaders aiming to harness platform convergence for innovation and sustainable development.

1. Introduction

The rapid emergence of diverse platform technologies is driving transformative changes in digital ecosystems and industrial innovation. Technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), blockchain, cloud computing, and advanced communication networks (5G/6G) are increasingly converging to form integrated, intelligent systems [1]. Rather than functioning in isolation, these technologies interact synergistically, enabling collaborative decision-making, adaptive operations, and sustainable growth across multiple domains. This phenomenon, referred to as platform convergence, is reshaping traditional business models, creating new value chains, and promoting innovation in areas including healthcare, finance, manufacturing, smart cities, and autonomous systems.

1.1. Background and Significance

Digital systems today increasingly rely on the integration of heterogeneous platforms, forming interconnected ecosystems that require interoperability, coordinated intelligence, and resilient architectures. While technologies such as AI, IoT, blockchain, cloud computing, and advanced networking each play critical roles [2], existing literature largely examines them in isolation or within narrow sector-specific contexts. However, no prior review provides a unified treatment of how communication standards, edge–cloud frameworks, data governance models, and trust mechanisms must align to enable true cross-sector platform convergence. Addressing this gap, this work offers a structured synthesis that clarifies integration mechanisms, emerging interactions, and multi-domain implications.

Platform convergence represents more than the coexistence of multiple technologies; it involves dynamic coupling among heterogeneous systems with complementary functions and shared data flows. From a systems perspective, such coupling can produce emergent behaviors where the combined system exhibits capabilities that exceed the sum of individual components. For example, AI-enabled IoT systems support predictive analytics and adaptive control, while blockchain contributes tamper-evident auditability and decentralized coordination. Yet these technologies must be carefully orchestrated: AI models may introduce opacity and bias, and blockchain alone cannot authenticate data origin. Their combination therefore requires principled governance to avoid amplifying systemic risks rather than mitigating them. Similarly, cloud and edge computing architectures enable distributed intelligence, but also create challenges of task allocation, latency management, and conflict resolution in multi-agent environments [3,4]. Understanding these interactions is essential for analyzing functional complementarity, data interdependence, and system-level coupling.

The convergence of platform technologies also underpins Industry 5.0 initiatives, emphasizing human-centric, sustainable, and personalized digital services. By harmonizing formerly siloed technologies, platform convergence enables more intelligent, resilient, and equitable systems that support the global digital economy [5]. Clarifying its mechanisms, challenges, and opportunities is therefore critical for guiding future research, technological deployment, and policy formulation.

1.2. Key Drivers of Collaborative Innovation

The convergence of AI, IoT, blockchain, cloud–edge architectures, and advanced networking is ultimately shaped by deeper economic, societal, and operational forces rather than by technological evolution alone. Economically, organizations increasingly pursue interoperable platforms to reduce integration overheads, enable shared service ecosystems, and support new value-creation models such as data marketplaces, pay-per-use intelligence, and cross-sector platform services. Societal expectations for resilience, sustainability, transparency, and real-time responsiveness further incentivize architectures capable of seamless data exchange, coordinated automation, and trustworthy decision-making across domains such as healthcare, mobility, manufacturing, and public safety. Regulation also plays a growing role, as requirements for traceability, privacy protection, and auditable automation encourage the adoption of unified, governance-aware platforms.

Operational pressures form a third major driver. Modern systems generate heterogeneous, high-volume data that must be processed, secured, and acted upon across distributed environments. This creates demand for platforms that combine sensing, computation, storage, analytics, and trust management within cohesive workflows. As digital infrastructures grow more interdependent, cross-domain orchestration—linking cyber, physical, and human actors—becomes essential for managing uncertainty, preventing subsystem conflicts, and maintaining service continuity.

Together, these economic, societal, and operational drivers—not data growth or computing power alone—explain why platform convergence represents a structural shift toward integrated, adaptive, and collaborative ecosystems. Technologies such as AI, blockchain, and cloud–edge computing serve as the means through which these motivations are realized. Their integration enables applications ranging from personalized healthcare and autonomous mobility to predictive manufacturing and secure multi-stakeholder collaboration, highlighting how broader forces shape the need for unified, cross-domain platform innovation.

1.3. Objectives of the Review

Despite the benefits of convergence, realizing a fully integrated platform ecosystem remains complex due to interoperability challenges, data governance, cybersecurity risks, ethical concerns, and inconsistent regulatory frameworks. Fragmented standards and heterogeneous implementations across industries further complicate adoption.

The primary objective of this narrative review is to provide a systems-level understanding of converging platform technologies, emphasizing collaborative innovations, interaction mechanisms, technical enablers, and emerging trends. Specifically, the paper provides:

• A timeline of platform convergence illustrating the evolution and integration of core technologies.
• A standards and frameworks map supporting cross-sector interoperability.
• A governance lens addressing trust, privacy, and regulatory compliance across domains.
• A research agenda highlighting emerging directions for AI, blockchain, and edge–cloud orchestration.
• A synthesis of technical enablers, sector-specific applications, and emerging trends guiding future innovation.

Given the conceptual and cross-disciplinary nature of platform convergence across AI, IoT, cybersecurity, distributed systems, and communication networks, a narrative review methodology is adopted. Unlike systematic reviews that aggregate empirical evidence using predefined protocols, this study synthesizes technological perspectives, identifies cross-domain patterns, and analyzes emergent trends. Figure 1 depicts the structure of this review, and Section 2 details the methodology.

The remainder of this paper is structured as follows: Section 2 describes the literature selection criteria. Section 3 explores fundamental concepts and integration mechanisms of key platform technologies. Section 4 reviews collaborative innovations across industries. Section 5 discusses technical enablers supporting seamless convergence. Section 6 addresses challenges including security, regulation, and scalability. Section 7 presents emerging trends and future research directions. Finally, conclusions are drawn regarding implications for academia, industry, and policy development.

2. Review Methodology

This work employs a narrative review methodology, focusing on synthesizing conceptual and technological developments rather than systematically aggregating empirical evidence. Given the interdisciplinary, dynamic, and multi-layered nature of platform convergence—encompassing AI, IoT, blockchain, edge–cloud computing, networking, and cybersecurity—a narrative approach is more appropriate than a systematic or scoping review. No new experimental data are presented; instead, the emphasis is on conceptual integration, technological interactions, and the identification of emergent system behaviors.

2.1. Literature Search Strategy

Unlike systematic or scoping reviews, which follow strict protocols optimized for empirical data aggregation, this review focuses on cross-domain synthesis, integration mechanisms, and the identification of emergent systemic effects. This approach enables critical analysis, highlights technological interdependencies, and identifies research gaps across technical, governance, and ecosystem dimensions. By clearly reporting the literature search strategy, inclusion and exclusion criteria, and the synthesis approach, the review ensures transparency and reproducibility appropriate for a narrative review.

3. Fundamental Concepts of Platform Technologies

The concept of platform convergence is rooted in the integration of multiple digital technologies that collectively enable intelligent, interconnected, and adaptive systems. Artificial Intelligence (AI), the Internet of Things (IoT), blockchain, cloud computing, and 5G each contribute distinct functionalities—intelligence, sensing, trust, computation, and connectivity—creating synergistic effects that go beyond simple aggregation. Understanding these technologies and their interactions from a systems perspective is essential to comprehending how convergence facilitates innovation, scalability, and resilience across domains.

3.1. Artificial Intelligence

Artificial Intelligence (AI) serves as the cognitive layer in convergent platforms, enabling autonomous decision-making, pattern recognition, and predictive analytics. AI interacts with IoT by processing sensor data, with blockchain by validating and analyzing secure transactions, and with cloud-edge systems by optimizing distributed computation. This functional complementarity allows emergent capabilities, such as predictive maintenance across heterogeneous devices and federated learning across organizational boundaries, where multiple AI models collaborate without exposing sensitive data [6]. From a systems theory perspective, AI acts as both a central controller and an adaptive agent, enabling dynamic feedback loops and emergent behaviors across the integrated ecosystem.

3.2. Internet of Things

The Internet of Things (IoT) provides the physical interface for data acquisition, connectivity, and actuation. IoT devices generate continuous streams of heterogeneous data, which are integrated through edge-cloud infrastructures. In convergence ecosystems, IoT enables process embedding: AI models interpret sensor data in real time, blockchain ensures secure logging of events, and cloud services provide high-level coordination. This data interlocking produces systemic effects such as enhanced situational awareness and adaptive system behaviors. For example, in healthcare, IoT-based monitoring combined with AI prediction and blockchain auditing enables both personalized care and regulatory compliance [7].

3.3. Blockchain Technology

Blockchain ensures data integrity, trust, and transparency within multi-stakeholder ecosystems. Beyond storing transactions, it embeds governance and verification mechanisms into operational processes. When combined with AI and IoT, blockchain facilitates decentralized intelligence: distributed consensus ensures reliable decision-making across autonomous agents, and smart contracts coordinate tasks between devices and services. From a complex systems perspective, blockchain introduces nonlinearity and robustness into the ecosystem, creating emergent properties such as trust-enhanced collaborative networks and resilient supply chains.

3.4. Cloud and Edge Computing

Cloud and edge computing together form the backbone for distributed computation, data storage, and orchestration. Edge nodes perform localized processing, enabling low-latency decision-making, while cloud platforms handle large-scale analytics, model training, and cross-system coordination. The interaction between edge and cloud illustrates process embedding: tasks are dynamically allocated based on system load, network conditions, and data sensitivity. This collaboration generates emergent systemic properties, such as self-optimizing workflows and adaptive resource allocation, which would not arise from isolated computing layers [8].

3.5. 5G and Next-Generation Connectivity

5G networks provide ultra-reliable, low-latency communication that interlinks AI, IoT, blockchain, and cloud components into cohesive ecosystems. Network slicing and quality-of-service guarantees allow the creation of virtualized sub-networks tailored to specific industrial requirements, such as real-time manufacturing control or remote healthcare monitoring. The connectivity layer enables multi-agent interactions, supporting complex orchestration and adaptive behaviors across heterogeneous systems [9]. Future 6G networks are expected to further enhance these systemic interactions by supporting higher device densities, immersive XR experiences, and integrated sensing-communication frameworks.

3.6. Interoperability and Cross-Platform Integration

Interoperability enables heterogeneous systems to exchange, interpret, and act upon data seamlessly. Achieving this requires functional complementarity, standardized protocols, semantic frameworks, and middleware orchestration. Beyond standard solutions, advanced approaches such as AI-based adaptive interfaces, decentralized identifiers (DIDs), and ontology-driven data translation are emerging to overcome vendor lock-in and siloed architectures. Effective interoperability transforms fragmented digital ecosystems into intelligent, self-organizing environments where AI, IoT, blockchain, and cloud-edge components collaborate dynamically [10].

3.7. Cross-Industry Insights and Systemic Implications

The convergence of platform technologies manifests differently across industries, shaped by domain-specific performance constraints, governance requirements, and risk conditions. For example:

• Healthcare: Real-time patient monitoring requires ultra-low latency, strict privacy compliance, and adaptive AI-driven analytics. These demands encourage edge–cloud coordination, federated learning, and blockchain-based auditability to maintain trust and data integrity.
• Manufacturing: IoT-enabled smart factories depend on high-throughput, deterministic communication and predictive maintenance across heterogeneous machinery. AI-optimized scheduling, digital twins, and closed-loop control systems enable rapid reconfiguration and reduced downtime.
• Finance: Convergence centers on data security, transaction immutability, explainable AI-driven risk analysis, and compliance automation. Blockchain and AI complement one another by enhancing fraud detection, auditability, and cross-institutional trust.

This cross-industry comparison demonstrates that convergence is not uniform: sectoral differences in privacy, latency tolerance, regulatory frameworks, and resilience requirements shape how technologies integrate and co-evolve. Failure cases—such as IoT deployments hampered by insufficient edge capacity, blockchain systems introducing latency that undermines real-time AI workflows, or interoperability breakdowns arising from incompatible ontologies—highlight the need for domain-sensitive integration strategies and governance-aware design principles.

In summary, platform convergence represents more than the aggregation of discrete technologies; it constitutes an interconnected, adaptive ecosystem exhibiting emergent properties. Functional complementarity, process embedding, and data interlocking remain central mechanisms through which convergence generates systemic benefits, including improved adaptability, resilience, and intelligent coordination. These foundational insights establish the conceptual groundwork for Section 4, which examines collaborative innovations and industry applications.

Converging platform technologies inherently increase system complexity due to multi-layer interactions across sensing, communication, computation, and governance layers. Effective complexity management relies on three coordinated mechanisms. First, architectural decomposition—through microservices, digital twins, and layered reference models—localizes complexity and enables modular evolution. Second, adaptive orchestration supported by AI-driven workload prediction, semantic mediation, and intent-based networking dynamically harmonizes heterogeneous components while minimizing latency propagation. Third, governance-level controls, such as policy abstraction, zero-trust security, and verifiable interoperability standards, ensure predictable behavior even as subsystems evolve autonomously. Together, these mechanisms enable convergent platforms to manage heterogeneity, uncertainty, and feedback loops, ensuring scalability and resilience across industries.

4. Collaborative Innovations and Industry Applications

This section synthesizes the recent literature on converging platform technologies and their applications across sectors. Table 1 summarizes the selected studies.

4.1. Healthcare

Recent studies highlight the convergence of IoT, AI, and cloud technologies in healthcare systems to enable continuous, data-driven patient monitoring [11]. Wearable devices, biosensors, and connected medical platforms generate multimodal data analyzed through deep learning models to detect anomalies and predict disease progression [12,13]. Edge computing reduces latency in emergency response, while blockchain ensures secure and tamper-proof medical record sharing. Integrating interoperable standards like HL7 and FHIR further enhances data portability across healthcare institutions. However, challenges persist in handling privacy-sensitive data, ensuring model interpretability, and achieving real-time cross-platform synchronization. Future research directions focus on federated learning, privacy-preserving AI models, and standardization frameworks for scalable healthcare interoperability.

Despite promising advancements, several healthcare convergence initiatives have encountered failures due to fragmentation and resource constraints. Many IoT-based hospital deployments have collapsed under insufficient edge resources, leading to delayed analytics and unreliable monitoring during peak loads. Similarly, blockchain-enabled medical record systems have failed pilot evaluations when consensus delays created latency incompatible with emergency workflows. Attempts to integrate AI diagnostics with EHR platforms have also been hindered by inconsistent data schemas and poor interoperability across hospital vendors. These failures highlight the need for standardization, robust edge provisioning, and governance frameworks tailored to clinical time-sensitivity and safety-critical decision-making.

4.2. Finance

The financial sector demonstrates strong adoption of converging platform technologies to improve transaction security, risk assessment, and personalized services. Blockchain, AI-driven analytics, and edge-cloud integration form the backbone of digital finance ecosystems. Smart contracts automate operations with minimal human intervention, while machine learning models enhance fraud detection, portfolio optimization, and customer segmentation. Cloud-based APIs and interoperable fintech platforms facilitate real-time collaboration between banks, insurers, and third-party providers. Nevertheless, cross-border regulatory differences, data privacy issues, and explainability of AI models remain pressing concerns. Ongoing research explores decentralized finance (DeFi) architectures, zero-knowledge proof systems, and hybrid blockchain models to enable transparent yet compliant digital finance convergence.

In the financial sector, several cross-platform convergence efforts have failed due to misaligned trust models and regulatory constraints. Early blockchain–AI fraud-detection systems failed when immutable but noisy transaction data amplified model bias, generating persistent false positives. Attempts to integrate IoT-based asset-tracking with banking platforms were abandoned when heterogeneous device identities could not satisfy Know-Your-Customer (KYC) and Anti-Money-Laundering (AML) requirements. Additionally, cloud–edge hybrid trading architectures have experienced instability during volatile markets due to unpredictable edge node behavior. These cases illustrate that financial convergence demands stringent data provenance mechanisms, regulatory alignment, and resilience against systemic risk propagation.

4.3. Manufacturing

Industry 4.0 represents the manufacturing domain’s most prominent convergence of IoT, robotics, and cyber–physical systems (CPS). Smart factories leverage sensor-rich environments, digital twins, and predictive analytics to achieve adaptive production and zero-downtime maintenance. Cloud–edge synergy supports distributed intelligence, allowing localized decision-making while maintaining centralized control and monitoring. Integration with 5G and AI-driven process optimization has accelerated mass customization and flexible automation. Despite these advances, interoperability among legacy systems, high data transmission costs, and cybersecurity risks hinder seamless platform convergence. Current research focuses on open manufacturing data models, blockchain-enabled supply chains, and self-optimizing production networks.

Several smart manufacturing initiatives have reported failures arising from poorly coordinated cyber–physical integration. IoT deployments on factory floors have failed when wireless interference or insufficient edge processing caused sensor dropouts, leading to inaccurate digital twins. Blockchain-based supply chain pilots have been discontinued when verification overhead slowed high-frequency production workflows. AI-driven predictive maintenance systems have also underperformed when heterogeneous machine data lacked common semantics, leading to model drift and unreliable forecasts. These failures demonstrate the need for harmonized data standards, low-latency verification models, and adaptive orchestration across cyber–physical systems.

4.4. Smart Cities

Smart city initiatives epitomize the concept of platform convergence by integrating IoT sensors, AI analytics, and cloud-edge computing to manage energy, transport, and public safety systems [14]. Converged infrastructures enable real-time traffic control, adaptive street lighting, and predictive maintenance of utilities. Data fusion from heterogeneous platforms enhances situational awareness and supports data-driven policy decisions. Furthermore, interoperability standards and open-data platforms foster citizen engagement and third-party innovation. Nonetheless, technical heterogeneity, limited scalability, and privacy regulations challenge large-scale adoption. Emerging research explores digital twins of urban systems, federated sensor networks, and AI-driven urban data governance to achieve sustainable and interoperable smart city ecosystems [15].

Smart city deployments frequently encounter failures due to large-scale heterogeneity and governance misalignment. Several sensor network programs have collapsed after integrating thousands of devices without adequate authentication, enabling cascading security breaches. AI-based traffic management systems have failed when imbalanced or siloed municipal datasets produced unstable or biased routing recommendations. Blockchain-based citizen identity pilots have been discontinued in some municipalities due to public resistance and slow transaction throughput. These cases emphasize that smart city convergence requires robust identity management, multi-stakeholder governance, and data harmonization across public agencies.

4.5. Autonomous Systems

Convergence in autonomous systems spans robotics, drones, and autonomous vehicles, combining AI perception models, edge computing, and high-speed communication networks [52]. These systems rely on real-time sensor fusion from LiDAR, cameras, and radar for situational understanding and safe navigation. Collaborative control frameworks enable multi-agent coordination across platforms, improving efficiency and adaptability in dynamic environments. Integration with 5G and V2X communications further enhances responsiveness and connectivity [53,54]. However, cross-platform synchronization, robustness under uncertain conditions, and ethical decision frameworks remain open challenges. Future directions include lightweight AI inference, edge–cloud co-optimization, and explainable autonomy for safer, transparent, and interoperable autonomous ecosystems.

Autonomous systems face notable convergence failures arising from edge unpredictability and cross-platform coupling. Multi-agent drone fleets using AI–IoT–edge integration have failed during field trials when communication latency spikes caused coordination conflicts and unsafe trajectories. Blockchain-based vehicular trust systems have been tested but often abandoned because consensus latency was incompatible with real-time control loops. Furthermore, AI-based perception models deployed across heterogeneous robotic platforms have exhibited inconsistent behaviour due to mismatched calibration and non-uniform sensor quality. These failures highlight the need for predictable latency bounds, cross-platform calibration protocols, and safety-aware trust architectures.

4.6. Cross-Industry Comparison

A comparative assessment across healthcare, finance, manufacturing, smart cities, and autonomous systems reveals that platform convergence follows recurring principles—functional complementarity, data interlocking, and embedded processes—yet manifests very different requirements and constraints in each domain. These variations highlight why sector-specific designs continue to dominate and why generalized convergence models remain limited.

4.6.1. Privacy and Data Governance

Healthcare and finance impose the strictest privacy and compliance requirements (HIPAA, GDPR, AML/KYC), demanding strong data provenance, access control, and explainability. Manufacturing and autonomous systems operate with lower privacy sensitivity but higher operational security, while smart cities face public acceptability challenges, requiring transparent governance and consent mechanisms.

4.6.2. Real-Time Performance and Latency

Autonomous systems and smart city traffic control require sub-second responsiveness, making heavy blockchain consensus or cloud-only processing infeasible. Manufacturing demands deterministic latency for cyber–physical coordination. Healthcare exhibits mixed latency needs—real-time monitoring versus batch analytics—while finance must ensure millisecond-scale performance for trading and fraud detection.

4.6.3. Trust Mechanisms and Risk Profiles

Financial and healthcare systems prioritize verifiable data provenance and auditable decision trails. Manufacturing and smart cities rely more on operational reliability and infrastructure-level trust. Autonomous systems face the highest systemic risk, as misaligned AI–IoT–edge coordination can result in physical harm. These differences shape how AI and blockchain are combined—or avoided—in each sector.

4.6.4. System Coupling and Interoperability

Manufacturing and smart cities involve tightly coupled cyber–physical infrastructures that amplify instability when components fail. Healthcare and finance operate through loosely coupled but highly regulated data platforms. Autonomous systems exhibit both tight control loops and distributed coordination, making them sensitive to unpredictable edge behavior.

4.6.5. Design Implications

This comparison shows that convergence architectures cannot be uniformly applied; instead, they require sector-specific adaptations in identity management, data standards, latency budgeting, governance, and trust modeling. Understanding these cross-industry differences is essential for guiding future research on unified architectures, semantic interoperability, and adaptive orchestration mechanisms capable of managing uncertainty and heterogeneity across domains.

5. Technical Enablers of Platform Convergence

The convergence of platform technologies is made possible by several core technical enablers that provide intelligence, connectivity, trust, and interoperability across systems. These enablers not only empower collaborative innovation but also address latency, security, and scalability challenges inherent in large-scale distributed ecosystems. Technical enablers are the foundational technologies that facilitate seamless integration, communication, and intelligent operations across convergent platforms. They enable functional complementarity, data interlocking, and process embedding across AI, IoT, blockchain, cloud-edge architectures, and communication infrastructures, producing emergent system properties beyond the mere stacking of technologies.

These enablers range from AI and machine learning, which provide predictive and adaptive capabilities, to IoT and edge-cloud integration, which ensure real-time sensing and distributed processing. Emerging communication infrastructures such as 5G/6G, blockchain for trust and transparency, and immersive technologies like digital twins and XR interfaces further enhance platform convergence by enabling high-performance, interactive, and secure ecosystems [55]. Importantly, the combination of these enablers generates synergistic effects—for instance, AI-driven edge analytics with blockchain-based trust mechanisms can simultaneously optimize decision-making, reduce latency, and enhance security, producing a systemic effect greater than the sum of individual technologies. Understanding these enablers, their interdependencies, and emergent behaviors is critical for designing effective and future-proof convergent platforms.

The technical enablers reviewed illustrate a diverse ecosystem of tools that collectively drive platform convergence. AI and ML support intelligent decision-making, while IoT and edge-cloud architectures provide low-latency processing and scalability. Blockchain ensures trust and transparency, and communication infrastructures like 5G/6G provide the necessary connectivity backbone [56]. Immersive technologies and digital twins offer predictive insights and simulation capabilities. Despite these advantages, challenges such as interoperability, security, computational cost, and standardization gaps persist, highlighting the need for ongoing research and cross-domain collaboration to realize fully integrated platform ecosystems.

Emerging trends point toward the integration of quantum computing for high-performance analytics, digital twins and extended reality for immersive simulation and real-time monitoring, and green computing strategies that prioritize energy-efficient and sustainable operations. Ethical, regulatory, and governance considerations are becoming equally critical, especially in sensitive sectors such as healthcare, finance, and smart infrastructure. The accelerated pace of development highlights the need for interdisciplinary collaboration across academia, industry, and policy sectors to ensure safe, responsible, and scalable adoption.

While these innovations are transforming the design, architecture, and operation of convergent platforms, they also expose unresolved gaps and practical challenges. Trends such as quantum acceleration, XR-based interfaces, and sustainable computing redefine technical possibilities but reveal the absence of mature frameworks for system-wide integration. Likewise, cross-domain data exchange and interoperability remain limited due to fragmented standards, inconsistent ontologies, and domain-specific constraints. Identifying and addressing these gaps is essential to guide future research and ensure that platform-level innovations translate into transparent, reliable, and socially responsible systems.

7.1. Technological Collaboration Mechanisms

As platform technologies converge, collaboration mechanisms play a central role in enabling coordinated, adaptive, and scalable system behavior. Three classes of mechanisms are increasingly prominent. First, functional complementarity integrates technologies with distinct capabilities—such as AI-driven perception with blockchain-based verification—to achieve outcomes unattainable by individual components. Second, process embedding aligns sensing, computing, and decision-making workflows across IoT, edge, and cloud layers, enabling real-time responsiveness and context-aware optimization. Third, data interlocking creates shared, interoperable data ecosystems where semantic alignment, multi-modal fusion, and cross-platform mediation support complex analytics and collective intelligence. Together, these mechanisms form the structural basis for coherent multi-technology ecosystems, supporting interoperability, robustness, and emergent system-wide behavior.

Despite advances in blockchain, federated learning, and decentralized identity systems, current trust mechanisms face several limitations. Blockchain introduces latency and computational overhead that conflict with real-time AI and IoT requirements. Federated learning reduces data exposure but remains vulnerable to poisoning, gradient leakage, and inconsistent client participation. Moreover, decentralized identifiers and verifiable credentials lack cross-domain standardization, limiting their applicability in heterogeneous environments. These limitations reveal the need for hybrid trust models that combine cryptographic assurance, behavioral analytics, and governance-layer verification to maintain reliability across dynamic, multi-stakeholder ecosystems.

7.2. Identified Research Gaps

Despite significant progress, several gaps persist across converging platform technologies. First, full cross-domain interoperability is hindered by the lack of unified reference architectures, standardized data models, and domain-agnostic ontologies. Second, ethical governance mechanisms for integrated AI–IoT–cloud ecosystems remain fragmented, limiting transparency and accountability. Third, sustainability considerations—particularly long-term resource lifecycle assessment and carbon-aware orchestration—are insufficiently embedded in current platform designs. Lastly, interdisciplinary collaboration frameworks remain underdeveloped, constraining the translation of technological advancements into policy and real-world impact.

7.3. Future Research Directions

Future research should combine architectural, ethical, and ecosystem-level perspectives to enable scalable and trustworthy convergent platforms. Key directions include:

• Developing unified reference architectures, standardized ontologies, and interoperability protocols for seamless cross-platform integration.
• Embedding emerging technologies such as quantum computing, digital twins, and extended reality within secure, resource-aware platform frameworks.
• Advancing privacy-preserving AI, decentralized trust mechanisms, and adaptive edge–cloud orchestration for resilience and transparency.
• Strengthening governance and regulatory frameworks to ensure accountable, equitable, and responsible system behavior.
• Establishing interdisciplinary collaboration models bridging industry, academia, and government to accelerate adoption and societal impact.

7.4. Conclusions

Converging platform technologies promise transformative impacts across healthcare, finance, manufacturing, transportation, smart cities, and autonomous systems. This review synthesizes core technological enablers, architectural paradigms, and emerging innovations while identifying opportunities and remaining challenges. Achieving truly intelligent, interoperable, and sustainable platforms will require not only technological advances but also robust governance mechanisms, unified standards, and coordinated cross-sector collaboration.

Ultimately, the future of convergent platforms will be defined by their ability to integrate diverse technologies into cohesive ecosystems that are adaptive, explainable, energy-aware, and resilient to systemic uncertainty. By addressing current limitations and fostering interdisciplinary innovation, next-generation platforms can evolve into scalable, trustworthy infrastructures that support societal well-being, economic growth, and sustainable technological progress.
