5 Important Microservices Design Patterns
<p><strong>Microservices design patterns</strong> have become increasingly popular due to their ability to improve software agility, scalability, resilience, and maintainability. Microservices design patterns are a set of principles and best practices used to develop and maintain software systems that are composed of small, independently deployable services.In this article, we will discuss the important microservice design patterns that can be used to create robust and efficient microservices architectures.</p>

It receives requests from clients and routes them to the appropriate service.</p>
<p><strong>How API Gateway Pattern works:</strong></p>
<p>The API Gateway pattern works by intercepting requests from clients and routing them to the appropriate service. When a client makes a request to the system, the request is first sent to the API Gateway. The API Gateway then checks if the request is authorized and if so, it routes the request to the appropriate service.</p>

For example, it can limit the number of requests that a client can make to a service in a given time frame. It can also cache responses from services to reduce the load on the underlying services.</p>
