Introduction
An ๐๐ฃ๐ ๐๐ฎ๐๐ฒ๐๐ฎ๐ is a server that acts as a single point of entry for a set ofย #microservices
๐๐ฃ๐ ๐๐ฎ๐๐ฒ๐๐ฎ๐ receives client requests, forwards them to the appropriate microservice, and then returns the server’s response to the client.
The ๐๐ฃ๐ ๐๐ฎ๐๐ฒ๐๐ฎ๐ is responsible for routing, authentication, and rate-limiting tasks. This enables microservices to focus on their individual tasks and improves the overall performance and scalability of the system.
API gateways are used for a variety of purposes in microservice architectures, including the following:
API Gateway ๐ฅ๐ผ๐๐๐ถ๐ป๐ด:
The API gateway receives client requests and routes them to the appropriate microservice. This enables clients to access the various microservices through a single entry point, simplifying the overall system design.
API Gateway ๐๐๐๐ต๐ฒ๐ป๐๐ถ๐ฐ๐ฎ๐๐ถ๐ผ๐ป:
The API gateway can be used to authenticate clients and enforce access control policies for the microservices. This helps to ensure that only authorized clients can access the microservices and helps to prevent unauthorized access.
API Gateway ๐ฅ๐ฎ๐๐ฒ ๐น๐ถ๐บ๐ถ๐๐ถ๐ป๐ด:
You can rate limit client access to microservices with an API gateway. This can help prevent denial of service attacks and other types of malicious behaviour.
API Gateway ๐๐ผ๐ฎ๐ฑ ๐ฏ๐ฎ๐น๐ฎ๐ป๐ฐ๐ถ๐ป๐ด:
The API gateway can distribute incoming requests among multiple instances of a microservice, enabling the system to handle a more significant number of requests and improving its overall performance and scalability.
API Gateway ๐๐ฎ๐ฐ๐ต๐ถ๐ป๐ด:
The API gateway can cache responses from the microservices, reducing the number of requests that need to be forwarded to the microservices and improving the overall performance of the system.
API Gateway ๐ ๐ผ๐ป๐ถ๐๐ผ๐ฟ๐ถ๐ป๐ด:
The API gateway can collect metrics and other data about requests and responses, providing valuable insights into the performance and behaviour of the microservices. This can help to identify and diagnose problems and improve the overall reliability and resilience of the system.
