The wholesale market is a growing business in Telco industries, facing direct impacts of new exploitable paradigms giving massive IoT, 5G, Edge, and Multiverse use cases, and needing to cope with ever increasing volumes. Hence, the order management must become flexible and scalable, with the ability of being distributed also over the Edge. With this vision in mind, our Client wanted to enhance its wholesale order manager (WOM) system, to be ready to endure the estimated future workloads: a cloud migration for WOM has been activated.
Challenges
- The project is the first exploiting the private OCI cloud of the Client, defining the way that private cloud will be used, for both problems and opportunities.
- Within the specific Cloud adoption, the adaptation of a monolithic architecture within a cloud natively scalable infrastructure has been the real challenge, due also to Client's Capex constraints: technological efficiency has been our answer.
- The introduction of the DevOps chain will be the cornerstone for the whole private cloud to use.
Solution
Sytel Reply and the Client designed a first step migration on the Cloud for the Order Manager components. The project is based upon a Uplift & Optimize approach, migrating the existing application on to the cloud, while upgrading al sort of libraries, enhancing the levels of hardening and security, and introducing a DevOps chain. The application has been re-written to allow containerization on a Kubernetes cluster; furthermore, decoupling of internal workflows allows a more resilient and microservice-based type of application architecture. Horizontal and vertical scalability are now easily enabled through the cloud infrastructure and application behaviour.
