This will allow engineers to optimise infrastructure cost, to improve disaster recovery and business continuity, and to streamline DevOps practices along with better security. Container adoption requires developers to apply portable practices including aspects related to persistence integration, network exposure, and secrets management. It also promotes process isolation and supports enhanced observability. Building on containerization, orchestration platforms (such as Kubernetes) can be used to drive the life cycle of independent services into a larger scale infrastructure. This paper describes the strategies employed at CERN to make a smooth transition towards an orchestrated containerised environment and discusses the challenges based on the experience gained during an extended proof-of-concept phase.
