In today's world, when the technology is changing fast, eliminating long-term commitment to a single technology stack is a significant advantage. Every Microservice can be built on a separate technology stack and can be redesigned, replaced, or upgraded independently as they execute in isolation. This means that every Microservice can be built using a different programming language and use a different type of data store which best suits the solution. This decreases the dependency concerns compared to the monolithic designs, and makes replacing services much easier.

A good example where this ability of a Microservice maximizes its effect is a scenario where different data stores can be used by different services in alignment with the business scenario they address. A logging service can use a slower and cheaper data store, whereas a real-time service can use a faster and more performant data store. As the consuming services are abstracted from the implementation of the service, they are not concerned about the compatibility with the technology used to access the data.
