One of the biggest challenges for teams starting off with microservices is adhering to the essential design principles. Part of this challenge arises from confusion about what exactly is a well-designed microservice. A microservices architecture requires a carefully constructed group of individual components that work together with efficiency. Let’s take a look at the 5 more important design principles in a Microservices architecture. 

• Single Concern – Restrict the entry points into a microservice to a single purpose. Let’s take an example here, a car trading organization wants an application that connects prospective traders with each other. One microservice component will deal exclusively with exchanging cars either by buying, selling, or trading them.

• Discrete – Data that a microservice requires to do its work should be isolated from other microservice. A microservice mostly requires its own configuration for the internals to operate, this configuration shouldn’t interfere with the configuration of another microservice. 

• Own Data – Each microservice carries its own data, but its data should also remain independent of all other microservice components. Sometimes, the microservice will share a database with others, but each microservice will have its own tables within the database.

• Transportable – A microservice should be transportable. This means that it can be packed up into a deployment unit such as a container image or a serverless function and deployed at any time via a CI/CD process.

• Ephemeral – An ephemeral microservice means that it can be destroyed at any given time and then resurrected to its last known state immediately.
