As telecoms operators continue to evolve in the rapidly transforming digital era, cloud-native business/operational support systems (BSS/OSS) is becoming the cornerstone of the agility needed for success in 2026 and beyond.
With telcos modernising their operations and speeding up service delivery under the growing pressure of cloud-first strategies, the cloud offers an approach suited to their needs. Still, leaping to cloud-native solutions is not without its own challenges. The path entails some degree of planning, incrementalism and attention to long-term goals to prevent chaos.
Telcos in 2026 can have their agility and keep their sanity, but for that to happen, they have to treat cloud-native BSS/OSS as a business transformation, not a technology flip.
Telcos will spend roughly US$80 billion on OSS/BSS software and services through 2028, with a CAGR of 5%, driven by cloud influence, 5G expansion and monetisation demand, according to Analysys Mason. Analysts concur that the inflection point is here, with investment and strategic plans increasingly focused on cloud-first architectures, hybrid multicloud operating models and greater automation. They further warn that unmanaged migration leads to operational chaos and cost overruns, with a fragmented customer experience.
Promise of cloud-native BSS/OSS
Cloud-native BSS/OSS solutions empower telecoms operators to be as agile as the environment they operate in. By moving to the cloud, telcos can shorten their time-to-market, bring in flexible billing schemes and improve customer experience. With a container-based deployment, API-first interfaces, end-to-end automation and modular microservice architecture, operators can quickly bring up services such as network slices, IoT bundles, or usage-based offerings, minimising operator intervention.
Clearly, the Appledore Research report emphasises this kind of agility, where early adopters experienced tangible improvements in time-to-market, facilitation of operational overhead and better closed-loop automation solutions.
Even so, disruption has its risks. Old mediation, inventory and charging platforms are still pervasive in many telcos. Technical dependencies, cultural inertia and stale data models can derail transformation if not planned carefully.
For instance, a recent IDC study, co-branded with Ericsson, states that OSS/BSS that is not modernised is one of the biggest inhibitors to growth for service providers due to limits on how quickly they can scale, iterate and monetise new use-cases. IDC’s larger cloud projection indicates that by 2026, almost two-thirds of enterprise application revenue will be derived from public-cloud software, which supports the need for service platform cloud-native transformation.
Deloitte also predicts that telecoms operators will focus on modernising their BSS and OSS to improve operational efficiency and customer experience, leading to a more integrated, agile digital infrastructure.
Pitfalls of cloud-native migration
While cloud-native BSS/OSS has the potential to bring the telco many benefits, the journey to these systems is full of challenges.
Ericsson’s OSS/BSS transformation report with IDC reveals that legacy systems are still holding back scale and agility. The shift to modular, containerised architectures enables telcos to support multi-partner ecosystems, real-time charging and deliver personalised services with more efficiency.
The practical risks to look out for are usually threefold, covering technical, operational and business concerns.
- Technical: Monolithic components, intertwined data models and non-API interfaces complicate transformation.
- Operational: Lack of skills in Kubernetes, site-reliability engineering (SRE), cloud governance and DevOps makes ‘cloud-native’ nothing more than a fantasy if runbooks and processes are not there.
- Business: Tying business to a major hyperscaler or vendor through a SaaS/BSS platform, or having unclear exit clauses, may result in desired agility turning into dependency.
The real-world successes highlight what the right modernisers are doing. Operators that initially isolated a limited scope (such as enterprise billing) and migrated that domain to a microservice, automated, API-driven runway experienced faster service launches, fewer defects and lower mean time to repair (MTTR).
Appledore claims that for OSS/BSS the path is already set, with an evolution that needs to be grounded in cloud, automation, intent and AI, with every service provider plotting its own pace. Also, early adopters are breaking ground as trusted pathfinders in this new cloud-native, AI-first paradigm.
Roadmap to sustainable modernisation
To dodge the traps and focus on delivering cloud-native BSS/OSS, IT and ops leaders should ideally follow a structured playbook:
Evaluate and decompose: Begin by assessing all business processes and associating them with binary outcomes in the business. Decompose monolithic applications into discrete, manageable services. Designate each as ‘replace,’ ‘refactor,’ or ‘retire.’ The phase will inform about what to prioritise and what has the highest urgency.
Demonstrate and industrialise: Showcase the value of cloud-native BSS/OSS in a targeted, high-impact pilot. Concentrate on key areas such as billing, customer management or order fulfilment as organisations begin to translate these domains into API-first, containerised services packaged via CI/CD pipelines with observability, automated testing and runbooks. Select a meaningful use case, for example, B2B digital service billing or 5G enterprise slicing, that can be scaled later on. Grow the pilot success into industrial-scale delivery by creating reusable components for wider deployment as the pilot matures. Link release gates and success criteria to concrete business results, not feature completion, and make sure ops, SRE and product teams train together on service logic and runtime performance.
Scale with governance: Once the pilot has proven itself, cloud-native operations can be scaled. Build in strong controls on variables to get consistency within the company. Get stricter with spending and make the vendors more flexible. Also, monitor service-level agreements (SLAs) with cloud providers on an ongoing basis to ensure they are meeting performance and security expectations.
Finally, it is important to remember that cloud-native BSS/OSS is not about removing complexity, but more about shifting complexity to different areas. Telcos that treat the journey as incremental product-capability work, build operational excellence at run time and embed commercial discipline in contracts and cloud usage can chase agility and avoid chaos.
Analyst data also makes it clear that the spend and capability shift is real, but the winners will be those who modernise with discipline and precision, not just speed.
Cloud-native BSS/OSS platforms provide telecoms operators with the flexibility to compete in an increasingly digital market, but success requires a well-defined strategy and disciplined execution. Telcos can capitalise on cloud-native benefits without the chaos of unmanaged transformation by learning from early movers, avoiding migration risks and following a clear roadmap.
The next-generation OSS/BSS market is expected to surge by 2026, driven by cloud-native architectures, 5G and 6G rollouts, IoT and edge integration, with growing demand for rapid service delivery. These BSS/OSS platforms will be moving beyond the pilot stage to full-blown adoption, enabling telcos to roll out services faster, scale effectively and connect to new ecosystems. However, real performance uplift will only be achieved where legacy constraints are broken, skillsets enhanced and commercial rigour applied.
