Kubernetes Enables Nokia Engineers to Focus on the Application Level; Saving 100’s of Hours with Every Release



Known for being the first name in mobile phones, Nokia’s core business is building telecom networks end-to-end; its main products are related to the infrastructure, such as antennas, switching equipment, and routing equipment. As a telecom vendor, Nokia was looking for a way to deliver their software to a plethora of infrastructures without changing the product itself.

Moving to containerization and cloud native technologies like Kubernetes allowed their team to have infrastructure-agonistic behavior in their products. For example, By separating the infrastructure and the application layer, they have less dependencies in the system, which means that it’s easier to implement features in the application layer. Teams test the exact same binary artifact independently of the target execution environment, allowing them to find more errors in early phases of the testing and not having to run the same tests on different target environments, like VMware, OpenStack or bare metal. As a result, they save several hundred hours in every release. Their engineers can focus more on the application level, and not on the infrastructure level.

Perhaps the biggest impact that Kubernetes is having on Nokia is that people are starting to think about how a telecom company can implement DevOps practices. Nokia is building a DevOps pipeline, which reaches from the actual developer to the customers, and get feedback from the customers right to the engineers. This is something that will fundamentally change how telecom companies are delivering software, and how quickly they can develop new features. Find out more by reading the case study.
