Choosing a persistent storage solution

Two of the biggest stateful application challenges in Kubernetes are storage orchestration and data management. There are an infinite number of solutions out there. First, we will explain the main storage attributes and topologies we need to consider when evaluating storage alternatives. Let's review the topologies used by the most common storage systems:

• Centralized: Traditional, or also referred to as monolithic, storage systems are most often tightly coupled with a proprietary hardware and internal communication protocols. They are usually associated with scale-up models since it is difficult to scale-out tightly coupled components of the storage nodes.
• Distributed: Distributed storage systems are more likely to be a software-defined solution and they may be architected to favor availability, consistency, durability, performance, or scalability. Usually, distributed systems scale out better than others to support many storage...
