Life after Affirmed: What operators should prioritize as 5G core strategies evolve

The global telecom ecosystem is entering a period of accelerated change as operators rethink how their mobile cores will support next-generation services. Microsoft's decision to wind down the Affirmed Networks application portfolio, which it initially acquired in 2020, has placed new urgency on both large and regional carriers that relied on these platforms for 4G and 5G service delivery. 

While the transition creates understandable concern, it also gives operators a rare opportunity to modernize their infrastructure in ways that position them for long-term competitiveness.

The providers that move quickly and strategically will be the ones best prepared for new enterprise and consumer use cases that demand reliability, low latency, and scalability.

A shifting market for mobile core platforms

The 5G core has become the centerpiece of how operators deliver value, enabling everything from enhanced mobile broadband to private networks and advanced IoT applications. However, as several vendors realign their business priorities, the market is consolidating. Affected platforms include virtual evolved packet cores (vEPC), standalone 5G core, and orchestration tools, which operators depend on to maintain reliable service for millions of users and deliver modern enterprise functionality.

Many providers now face the challenge of replacing critical systems and preparing for the next wave of 5G innovation, including standalone deployments, network slicing, and high-performance enterprise use cases.

Telecom teams navigating this shift should focus on several foundational areas as they identify their next-generation core strategy:

• Modern cloud-native design: The move toward cloud-native, microservices-driven cores has become essential for scaling 5G networks. Newer platforms use containerized architectures and open APIs to offer greater flexibility across environments spanning multiple vendors. Providers should look for solutions that operate across hybrid and multi-cloud models so they can work seamlessly with existing systems while supporting long-term growth.
  
  
• Cost-aligned operations: Older platforms often carry heavy maintenance and infrastructure costs. Cloud-native systems reduce total cost of ownership by automating routine workflows, simplifying orchestration, and eliminating infrastructure overhead. This is especially important for operators competing in tight-margin markets or launching private networks for enterprise customers.
  
  
• Migration without disruption: A seamless cutover is essential. Operators should seek solutions with modular, interoperable components that minimize service impacts and shorten deployment windows. Access to hands-on engineering support can make a huge difference, particularly for MVNOs and regional networks with limited technical resources.
  
  
• Support for expanding use cases: A modern core platform must be flexible enough to handle a wide range of demands, whether supporting large consumer networks or powering latency-sensitive enterprise environments. Capabilities such as 3GPP-compliant network slicing, real-time analytics, and private LTE or 5G deployment options are increasingly important for operators pursuing IoT initiatives, Industry 4.0 projects, or smart city applications.
  
  
• Vendor adaptability and commitment: The market for core network vendors is tightening as some providers step away and more adaptable, innovative providers gain momentum. Operators benefit most from partnering with vendors that have a clear roadmap, a sustained commitment to fast-moving product development, and reliable access to hands-on engineering expertise.

New opportunities created by the transition

While the sunsetting of a widely deployed platform can be disruptive, it also forces important decisions that many operators may have postponed. Adopting modern cores not only strengthens service continuity but also creates opportunities for revenue growth and differentiation.

Providers can expand into private wireless networks for manufacturing and logistics, offer tailored slicing services for enterprise customers, and improve overall performance through real-time analytics.

Emerging vendors such as AxyomCore are entering this space with lightweight and cost-effective solutions built for MVNOs, regional operators, and greenfield deployments, groups that often do not receive the level of support they need from larger hyperscalers.

Preparing for what comes next

As 5G capabilities mature, the operators that thrive will be those that turn today’s market changes into long-term advantages. That requires clear assessments of current deployments, intentional migration strategies, and a focus on platform partners who offer both technical innovation and telecom-specific expertise.

The sunset of Affirmed Networks’ applications underscores a broader truth: the mobile core is evolving quickly, and operators have a timely opportunity to modernize their environments. By embracing cloud-native architectures, prioritizing operational efficiency, and selecting vendors committed to next-generation development, providers can build the foundation required to deliver the advanced services that define the 5G era.
