Microservices architecture is a software development approach where an application is built as a collection of small, loosely coupled, independently deployable services. Each service focuses on a specific business capability and operates as an autonomous unit, communicating with other services through well-defined APIs. This architectural style is often used in the context of DevOps to create more efficient, scalable, and manageable systems.

In today's world of container-based applications, the role of storage has become more critical than ever. One of the most significant challenges of containerization is the management of stateful applications. Kubernetes, one of the popular container orchestration platforms, provides a solution to this problem - Persistent Volumes (PVs). PVs allow the storage provision to be decoupled from the lifecycle of the Pod, making it easier to manage stateful applications.
