Definition

An API Gateway is a software layer that sits between your back-end services and your API clients. Its job is to act as a reverse proxy, routing requests from clients to the appropriate backend service and then returning the service's response back to the client.

Benefits

One of the main benefits of using an API Gateway is that it can abstract away the underlying complexities of your back-end services. This can make it easier for developers to build and consume APIs, since they don't need to worry about the specifics of each service.

API Gateways also provide a number of other benefits, including:

Load balancing: An API Gateway can distribute incoming requests across multiple back-end servers, helping to improve the scalability and reliability of your API.
Caching: An API Gateway can cache the responses from your back-end services, reducing the load on those services and improving the performance of your API.
Security: An API Gateway can enforce security measures such as authentication and rate limiting, helping to protect your back-end services from malicious attacks.
Monitoring: An API Gateway can provide detailed logs and metrics on the traffic flowing through it, making it easier to monitor the health and performance of your API.

Vendors & products

There are many API Gateway products and vendors to choose from, each with their own unique set of features and pricing plans. Here are a few popular options:

AWS API Gateway: This is a fully managed service from Amazon Web Services that makes it easy to create, publish, maintain, and secure APIs.
Kong: This is an open-source API Gateway built on top of NGINX, with a number of plugins available for extending its functionality.
Apigee: This is a cloud-based API Gateway from Google that provides a range of features for designing, securing, and scaling APIs.
Tyk: This is another open-source API Gateway that offers a number of features for managing and monitoring APIs, including support for microservices architectures.

Conclusion

Whether you're building a new API or looking to improve the performance of an existing one, an API Gateway can be a valuable tool in your toolkit. So why not give one a try today and see how it can benefit your API!
