Cloud-Native Network Function Migration Services Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Cloud-Native Network Function Migration Services Market Trends and Insights

5G Standalone Core and Network Slicing Rollouts

5G standalone cores require cloud-native functions and therefore create direct demand for migration work. Telia Norge launched nationwide commercial 5G standalone service in 2026 and reported latency below 10 milliseconds, compared with 15-18 milliseconds on non-standalone 5G. Proximus launched 5G+ in Belgium in April 2026, adding another commercial rollout that requires cloud-native core capabilities. Network slicing depends on standalone architecture because it needs dynamic allocation of network resources across users and services. The cloud-native network function migration services market benefits when operators bring these capabilities into commercial use rather than maintaining non-standalone networks. ETSI standards provide a shared technical framework for validating service-based network architecture during these migrations.^{[1]“ISG MEC, Multi-access Edge Computing,” ETSI, etsi.org}

Hybrid and Multi-Cloud Telco Modernization

Operators increasingly use both public cloud resources and infrastructure inside their own data centers. O2 Telefónica deployed a 5G cloud core on Nokia software running on AWS Outposts in its data centers in March 2026, while serving 1 million customers through this hybrid model. This model combines public-cloud operating tools with local control over sensitive network workloads in the cloud-native network function migration services market. It also makes platform portability more important because operators need functions to operate across different locations and cloud environments. The cloud-native network function migration services market gains from this complexity because migration partners must design, test, and operate the links between cloud platforms. China Telecom identified cloud-native network element evolution and edge AI integration as pillars of its 2026-2030 cloud-network fusion phase.

OPEX Optimization Through VNF-to-CNF Transformation

Operators are looking for a lower-cost operating model as they move from virtual network functions to containerized functions. Containerized functions can scale more easily and can reduce the fixed capacity that operators keep for peak traffic. The cloud-native network function migration services market is supported when automation shortens deployment cycles and reduces manual lifecycle work. China issued YD/T 6719-2026 in March 2026, setting technical requirements for the container-layer operations and maintenance northbound interface, with the standard taking effect in June 2026.^{[2]“Network Function Virtualization Management and Orchestration Technical Requirements,” China Communications Standards Association, cnis.ac.cn} The standard gives providers and operators a clearer operational reference for container-layer management. Repeatable operating practices can reduce migration risk, especially for operators managing large multi-vendor estates.

Edge Cloud Deployment for Low-Latency Services

Edge deployments extend migration work beyond the mobile core and into distributed network locations. NEC expanded its user plane function support for second-generation AWS Outposts in February 2026 and reported 200 Gbps throughput using 20% of total CPU cores. This performance profile supports the use of cloud-native user plane functions alongside other workloads at edge sites. ETSI’s Multi-access Edge Computing group provides specifications for multi-provider and multi-technology edge deployments. The cloud-native network function migration services market can therefore address user plane functions and application hosting, not only central core functions. These projects require local performance testing and coordinated deployment across edge and central sites.

Legacy OSS and BSS Integration Complexity

Legacy operating support systems and billing support systems remain a practical barrier to cloud-native migration. Established operators often run several OSS and BSS platforms because of earlier acquisitions and separate network deployments. These systems can contain proprietary interfaces and undocumented dependencies that are difficult to connect to containerized network functions. The cloud-native network function migration services market needs experienced integration teams when network provisioning, billing, and service assurance must remain active throughout a cutover. Manual steps can remain necessary when the legacy layer lacks usable programmatic interfaces. This weakens the speed and cost benefits that operators expect from cloud-native automation.

Telco-Grade Interoperability and Performance Gaps

Cloud platforms designed for general enterprise workloads do not automatically meet all carrier network requirements. Operators require consistent availability, deterministic packet processing, and reliable real-time behavior across the full service chain. They must test cloud infrastructure, network functions, and management tools together before carrying production traffic. The cloud-native network function migration services market is affected because these validation cycles can prolong migration schedules. Hybrid operation of VNF and CNF environments also creates a risk that operators delay a cutover to avoid service disruption. A shortage of staff with both cloud and network operations experience can make these tasks harder to complete at scale.

Segment Analysis

By Component: Services Support Current Programs, While Solutions Lead Growth

Services held 69.12% of the cloud-native network function migration services market share in 2025, reflecting operators’ continuing need for integration, consulting, validation, and managed migration support. Migration programs commonly require detailed function inventories, transition planning, dependency mapping, parallel operation, and production validation. Those requirements favor service engagements when a network includes multiple vendors and older operating platforms. Professional services providers also help operators coordinate network operations teams, application owners, security teams, and cloud infrastructure partners.

Solutions are projected to expand at a 16.11% CAGR through 2031, faster than the overall cloud-native network function migration services market. The segment includes migration automation tools, lifecycle management software, and platforms that support containerized network functions. Productized tools can make deployments more repeatable across separate clusters, release cycles, and technology vendors. They can also reduce the amount of bespoke configuration needed during later migration waves and routine software updates. Deutsche Telekom’s Operator-based Cloud Automation Solution uses Kubernetes operator patterns and GitOps principles for lifecycle management. Its approach shows why operators are seeking tools that can manage stateful functions and cross-cluster dependencies in a more standardized way.

By Deployment Model: Cloud Service Providers Lead the Transition

Cloud service providers held 53.62% of revenue in 2025 and are projected to expand at a 15.98% CAGR through 2031. Public-cloud deployment gives operators access to elastic infrastructure without the full cost and timing of building new data center capacity. It can also provide managed platform services that support Kubernetes-based deployment and operations. This makes cloud-hosted environments attractive for new standalone core programs that need rapid capacity changes. The cloud-native network function migration services market therefore requires services that connect network-specific functions to public-cloud operating models, security controls, and operating procedures.

Tune Talk became ASEAN’s first fully cloud-native mobile network operator in February 2026 through a Mavenir deployment of cloud-native core, OSS, and BSS solutions on AWS infrastructure. Nokia and Citymesh also brought a commercial mobile service using 5G Core SaaS into operation on AWS in February 2026.^{[3]“Citymesh Goes Live with World’s First Commercial Mobile Service on 5G Core SaaS,” Nokia, nokia.com} These deployments indicate that public cloud can support commercial mobile workloads when the required performance, security, and operational safeguards are in place. On-premise environments still matter for latency-sensitive functions, data sovereignty needs, and operators with substantial existing data center capacity. As a result, hybrid orchestration remains a central requirement rather than a temporary transition stage for many established operators.

By Network Function Domain: Core Functions Lead Revenue, Open RAN Grows Faster

5G Core and Evolved Packet Core held 35.14% of revenue in 2025. This position reflects the need to establish cloud-native core functions before operators can fully use standalone 5G capabilities. Mavenir migrated the first 100,000 Telefónica Germany customers to cloud-native IMS on AWS in May 2026. Nokia’s cloud-native IMS and subscriber data management functions became commercially active at Rakuten Mobile on Rakuten Cloud in March 2026. 

Radio Access Network and Open RAN are projected to record a 16.08% CAGR through 2031. The domain expands the scope of the cloud-native network function migration services market from central core workloads into access-network functions. Rakuten Mobile’s cloud-native Open RAN network provides an operating example for this approach across a large population footprint. Open RAN migration requires detailed interoperability testing because it brings together radios, software, cloud infrastructure, and management layers from different suppliers. Edge and multi-access edge computing are also relevant because user plane functions must operate close to users for low-latency services. Other functions, including policy control and signaling, are commonly migrated as part of wider standalone-network programs and coordinated service releases.

By End User: Telecom Providers Remain the Main Buyers

Telecom service providers held 49.91% of revenue in 2025, making them the principal buyer group. Large operators have complex network estates and undertake migration over several years, often across core, voice, access, edge, and service-management functions. Their programs require coordination between network equipment suppliers, cloud providers, systems integrators, and internal operating teams. Telecom service providers also need to preserve service continuity while moving live subscribers and applications. These needs sustain demand for planning, implementation, and managed operations services.

Cloud service providers are expected to grow at a 15.89% CAGR through 2031 as they embed CNF workloads into managed platform services. Ericsson and Google Cloud introduced Ericsson On-Demand in June 2025 as a fully managed 5G Core SaaS offering built on Google Kubernetes Engine. This model changes the buyer landscape because a platform provider can package network functions with cloud operations, billing, and managed support. Large enterprises and government and defense organizations add demand where private-network reliability and security needs are important. Small and medium-sized enterprises typically obtain CNF-based capabilities through managed providers rather than buying migration services directly. That reseller model gives cloud providers a larger role in the cloud-native network function migration services market.

Geography Analysis

North America held 34.90% of the cloud-native network function migration services market share in 2025. The region has large operators that are moving from initial standalone core deployment into voice, edge, enterprise service, and service-assurance work. A dedicated 5G standalone core for FirstNet shows the role of cloud-native architecture in public safety networks. The region also benefits from an active ecosystem of cloud providers, network vendors, and systems integrators. Interoperability testing by the O-RAN Alliance gives operators a basis for validating multi-vendor access-network deployments.

Europe has mature migration programs in Germany, the United Kingdom, France, and other Western European markets, while Central and Eastern European operators remain earlier in deployment cycles. O2 Telefónica’s hybrid cloud core deployment illustrates how regional data sovereignty requirements can coexist with public-cloud operating methods. The European Commission published the Telco Cloud Reference Architecture in September 2025, providing a regional reference for interoperable and sovereign telco cloud design. Proximus’s April 2026 5G+ launch and Telia Norge’s nationwide commercial 5G standalone rollout indicate continued momentum.

Asia-Pacific is projected to expand at a 16.13% CAGR through 2031, the highest regional growth rate in the cloud-native network function migration services market. NTT DOCOMO and NEC launched Japan’s first commercial 5G core on AWS in March 2026, using agentic AI and GitOps automation that reduced design and construction time by 80%. China’s YD/T 6386-2025 standard established design and management principles for cloud-native telecom network elements. SK Telecom released an autonomous network Level 4 blueprint in June 2026 that includes next-generation OSS transformation and AI agent standardization. India’s Open RAN expansion and Southeast Asia’s greenfield operators broaden regional demand, while the Middle East, South America, and Africa remain earlier-stage areas with selected cloud-native projects and targeted international partnerships.
