What are Microservices?
Microservices, also known as microservice architecture, refers to an architectural style that structures an application
as a collection of loosely coupled, independently deployable services. Each microservice is self-contained and should
implement a single business capability.
For example, in an e-commerce application, you might have separate microservices for user management, product catalog,
order management, and payment processing.
Benefits of Microservices Architecture
Microservices architecture offers several benefits, including:
Scalability : Each microservice can be scaled independently based on demand, thus enhancing the application's performance and overall Scalability .
Isolation : Since each microservice is separate, failures are isolated and don't affect the entire system.
Flexibility : Developers can use different technologies and languages for different microservices, based on what best
suits the service's needs.
Microservices Architecture Components
Key components of a microservices architecture include:
Service Registry : This is where all microservices are registered, allowing for easy discovery and communication.
API Gateway : This API Gateway acts as a single entry point into the system. It directs requests to appropriate microservices and consolidates responses.
Microservice : Each microservice is a small application that has its own hexagonal architecture consisting of business
logic along with various adapters.
Microservices vs Monolithic Architecture
In contrast to microservices, monolithic architecture builds an application as a single, indivisible unit. While simple
to develop, monolithic applications can become unwieldy as they grow, limiting scalability and increasing risk.
Conclusion
Understanding what are microservices and their architecture is essential in today's cloud-native world. They offer
increased scalability, resilience, and flexibility compared to traditional monolithic architectures. As you continue
your learning journey, remember that the best architecture depends on your project's needs and team's capabilities.
With this beginner-friendly glossary to microservices architecture, you're well on your way to implementing these
powerful structures in your future projects. Embrace the change and watch your applications thrive!
