On Recent Advances on Stateful Orchestrated Container Reliability

Thanks to its flexibility and light weight, containers are becoming the primary platform to run microservices. Container orchestration frameworks - like Kubernetes or Docker Swarm - enable companies to stay on competitive edge by keeping the velocity of code deploys high. While containers are ideal for stateless workloads, using orchestrated containers for stateful services is also an option. Being a commodity and crucial to any business, state or, in other words, data has to be protected and be available. This research raises questions on what the reliability challenges of running stateful microservices are, and what are the recent approaches to increase reliability of stateful services in orchestrated container systems. A literature review was performed to answer the questions.
