Decentralization or self-governance

While working with microservices, there is often a change of failure. A contingency plan that eventually stops the failure from propagating to the entire system. Furthermore, each microservice may have its own data storage need. Decentralization manages just the need for that. For example, in our shopping module we can store our customer and his transactions-related information in SQL databases, but since the product data is highly unstructured, we store it in NoSQL-related databases. Every service should be able to take a decision on what to do in fail case scenarios.
