Streamlined Efficiency: Telco BSS for 5G Success

Microservices architecture :

The BSS applications built on microservices based architecture consist of loosely coupled small services which operates together and improves applications flexibility, scalability and enable faster launch of services. These small services are event driven and enable real-time communication between services. These services can be added, removed, or modified without interrupting the application functionality.
The microservices architecture also supports open API's, which can be consumed and invoked by source and targeted systems, thus fostering seamless communication between applications. 

Cloud-native architecture : Cloud native architecture reduces the operating expenditure and drives automation but requires technology and organizational changes to handle higher data volumes and dynamic service offerings.
Cloud native applications are quicker and easier to deploy, manage and automate traditional tasks, thus while moving towards a 5G network which involve higher data consumption and low latency for 5G use case, cloud native application is an important strategy for a telecom operator to monetize their 5G network.
