An 𝗔𝗣𝗜 𝗚𝗮𝘁𝗲𝘄𝗮𝘆 is a server that acts as a single point of entry for a set of #microservices
𝗔𝗣𝗜 𝗚𝗮𝘁𝗲𝘄𝗮𝘆 receives client requests, forwards them to the appropriate microservice, and then returns the server’s response to the client.
The 𝗔𝗣𝗜 𝗚𝗮𝘁𝗲𝘄𝗮𝘆 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 𝗥𝗼𝘂𝘁𝗶𝗻𝗴:
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 𝗔𝘂𝘁𝗵𝗲𝗻𝘁𝗶𝗰𝗮𝘁𝗶𝗼𝗻:
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 𝗥𝗮𝘁𝗲 𝗹𝗶𝗺𝗶𝘁𝗶𝗻𝗴:
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 𝗟𝗼𝗮𝗱 𝗯𝗮𝗹𝗮𝗻𝗰𝗶𝗻𝗴:
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 𝗖𝗮𝗰𝗵𝗶𝗻𝗴:
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 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴:
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.
