As microservices architectures have become increasingly prevalent in modern software systems, they’ve brought both tremendous benefits and significant challenges. One of the most pressing challenges has been maintaining performance at scale while dealing with complex service dependencies and network communication overhead.
In a recent blog post, we discussed object-inspired container design patterns in detail and the sidecar pattern was one of them. In a sidecar pattern, the functionality of the main container is extended or enhanced by a sidecar container without strong coupling between two. This pattern is particularly useful when using Kubernetes as container orchestration platform. Kubernetes uses Pods. A Pod is composed of one or more application containers.
