Design Microservices Architecture with Patterns and Principles - What Are Microservices?

Microservices are small, independent services that can be deployed autonomously. They communicate via APIs, allowing teams to update services without affecting the entire application. Each service can use different technology stacks and has its own database, differing from traditional models. This flexibility and independence make microservices a powerful architecture for modern applications.

What is a key characteristic of microservices that allows them to be managed by small development teams?

• They are large and complex.

• They are small and independent.

• They require a shared database.

• They use a single technology stack.

How do microservices typically communicate with each other?

• Via network protocols and APIs.

• By sharing the same database.

• Using direct function calls.

• Through shared memory.

What is one of the main advantages of deploying microservices independently?

• It mandates using the same technology stack.

• It complicates the deployment process.

• It requires a complete application rebuild.

• It allows for individual service updates.

Why are microservices considered technology agnostic?

• They require a unified development team.

• They must use the same programming language.

• They can work with various technology stacks.

• They rely on a single database system.

How do microservices handle data persistence differently from traditional models?

• They do not use databases.

• They rely on external data centers.

• Each service has its own database.

• They share a common data layer.
