5 fundamental principles of Microservices design

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.
