The Future of OSS/BSS Architecture Is Cloud-Native and Microservices

Without the right OSS/BSS architecture, telcos will never realize the full potential of 5G services. Customers demand faster, more reliable, and personalized telecom services, and the bar keeps getting raised. Outdated legacy systems struggle to keep pace with the complexity of 5G infrastructure and network operations. However, scaling these static operational support systems (OSS) and business support systems (BSS) every few years is costly and ineffective.

BSS and OSS system architecture

Adopting a microservices-based cloud-native OSS/BSS architecture solves this problem. It allows telecom operators to update individual system components without rebuilding the entire system. This approach enables service provisioning, fault management, and network management to be controlled independently. This way, telcos achieve seamless scaling of OSS and BSS system design by adding new services or expanding capacity as demand grows, all without costly infrastructure upgrades or disrupting telecommunications networks.

As a trusted tech partner to many telcos, we at Flyaps are big fans of flexible solutions — and cloud-native architecture is one of the best for transforming the telecommunications industry in our opinion. Now is the perfect time to transition to such flexible systems and remain competitive against those who have already moved from cloud computing to cloud-native architectures. Further, we will discuss what advantages cloud-native brings to OSS/BSS architecture and how you can make the most out of this combination.

Why move your telecom OSS architecture and BSS system design from cloud computing to cloud-native?

To start, let’s clarify the difference between traditional cloud computing and cloud-native architecture.

Cloud computing is about hosting existing systems and services on the cloud. This often means that monolithic applications are moved from local servers or personal devices to the cloud with minimal changes. On the other hand, cloud-native architecture involves building and running applications specifically designed for the cloud. In simple terms, cloud computing is about using the cloud to host services, while cloud-native is about building applications that are “born in the cloud.” 

Cloud-native applications

In the telecom industry, operational support systems and business support systems are critical to managing operations, from network management and service provisioning to revenue management and customer relationship management (CRM). OSS/BSS in telecom must undergo transformation to keep pace with technological trends like network function virtualization (NFV), software-defined networking (SDN), and 5G. Moving traditional OSS/BSS applications to the cloud without redesigning them may seem like a quick and cost-effective approach, but it limits their potential.

Telecom cloud infrastructure

Moreover, popular cloud tools and approaches, like containers (Docker) or orchestration tools (Kubernetes), can't be fully used with legacy monolithic systems. Designing and developing your BSS/OSS system architecture for cloud environments from the ground up also allows telcos to get more out of the microservices approach. That’s the key element that makes cloud-native architecture so powerful, especially in supporting effective OSS/BSS transformation.

How microservices-based architectures work for OSS/BSS system design

Imagine a telecom operator managing a legacy, monolithic system to handle their billing, customer relationship management, and network operations. In this traditional OSS and BSS setup, all these functions are bundled together, making any update or change a slow and costly process. For instance, if they wanted to add a new billing feature to support a new 5G service, they would have to update the entire system, potentially disrupting other critical functions like customer management or network inventory.

With a microservices-based architecture, these functions are broken down into independent services. So, if the operator needs to add a new billing feature to their business support system, they can update just the billing microservice.

Microservices architecture

Additionally, scaling becomes easier. Let’s say the demand for 5G services grows rapidly, and the operator needs to expand their network management capabilities without needing to upgrade the entire system. This improves network efficiency and saves on operating network infrastructure costs.

With that said, here are the key advantages of microservices for telcos:

  1. Teams can work on different services simultaneously, enabling faster updates and feature releases without impacting the entire system.
  2. Since each microservice operates independently, a failure in one service doesn’t bring down the entire system.
  3. Each microservice can be built using different programming languages or technologies, allowing developers to choose the best tools for each task.

Microservices are crucial if you work with modern cloud computing technologies. Therefore, since everything is clear about cloud-native and microservices in general, let's shift to the practical steps to transforming OSS/BSS system design with cloud-native.

Steps to transitioning to microservices for OSS/BSS architecture in telecom

Let’s see what you should do to successfully move your monolithic OSS/BSS system to microservices. 

Prioritize business processes 

Before you start breaking down your monolithic system, pinpoint the processes that will most benefit from being modernized. They'll be the first to be targeted for improvement. Focus on core functions that have a significant impact on revenue or customer experience, such as billing, service activation, or fault resolution, as these are critical to operational efficiency and growth.

Evaluate legacy systems 

Begin by complementing your legacy systems with cloud-native elements, for instance, by adding microservices for provisioning new services. This hybrid model allows your legacy systems to continue supporting current operations while new functionalities can get migrated to the cloud over time, minimizing the number of operational risks and ensuring business continuity.

Use industry-standardized tools  

To maintain flexibility and avoid vendor dependency, it’s essential to adopt open-source and standardized tools for development and deployment. Kubernetes (for managing containers), Docker (for service deployment), and Jenkins (for continuous integration and delivery) are widely used solutions that enable seamless management of microservices and simplify future scaling and updates. 

Design for scalability

Microservices architectures should be built with scalability in mind. Unlike monolithic systems, where scaling involves adding resources for the entire application, microservices allow operators to scale specific components based on real-time usage, improving efficiency and resource management. For example, if there's a sudden surge in new customer sign-ups, the provisioning microservice can be scaled up temporarily without the need to increase resources for the entire OSS/BSS system.

Ensure security protocol compliance 

Microservices require consistent security protocols like encrypted communications (TLS), API security, and OAuth for authentication to ensure data is protected across the system.

Design for future seamless integration

Using standard communication protocols like RESTful APIs allows different services to interact seamlessly with each other, making it easier to extend the architecture over time.
