A Simplified Explanation of an API Gateway

An API Gateway is a service that sits in front of an organization’s API infrastructure and manages all API traffic. It can act as a single entry point for all API calls, providing a unified platform for managing API access, security, rate-limiting, and performance. API Gateways can also optimize API traffic, routing API calls to the appropriate backend services and caching responses to improve performance.

Your gateway manages security, authentication, and API orchestration.

API Gateways provide a simplified explanation of an API, manage security and authentication, and API orchestration. An API Gateway is a critical element of cloud-based architectures and microservices-based deployments, providing a unified interface to multiple services.

How does an API Gateway work?

API Gateway is a web service that sits in front of an organization’s back-end systems and provides a unified interface to those systems. In addition, API Gateway provides a simplified interface for clients accessing back-end systems and enforces security and throttling policies for back-end systems. API Gateway also handles load balancing for back-end systems.

It acts as a single entry point for all external API calls

An API Gateway is a single access point for all external API calls. A reverse proxy sits in front of your back-end services and routes requests to the appropriate services. It also caches responses from the back-end services, which improves performance and data modernization and reduces the back-end services’ load.

Create a gateway function.

API Gateway is a web service that sits in front of your web or mobile app and acts as a single point of entry for all your app’s API calls. API Gateway accepts requests from client apps, authenticates and authorizes them, then routes them to the appropriate back-end service. It also handles caching, load balancing, and security.

Use a gateway to throttle requests, handle authentication and authorization, and cache responses.

An API gateway is a system that sits in front of an API and handles all the requests for that API. It can throttle requests, manage authentication and authorization, and cache responses. This allows the API to be much simpler since it doesn’t have to worry about all the different types of requests that can be made. It can also streamline data analytics over time.

The API gateway can also modify the requests and responses before they are sent to and from the API. This can be used to add security and performance enhancements or alter the data somehow.

Create a resource.

API Gateway provides a simplified interface to web services that clients can invoke. API Gateway allows you to create, manage, and monitor resources that represent web services. You can create and manage resources using the API Gateway console or the API Gateway REST API. Resources can be defined in various formats, including Swagger definitions, RAML definitions, and WSDL documents. An API Gateway definition often provides a built-in proxy for invoking web services.

Why do you need an API Gateway?

API gateways provide a way to manage the APIs used by an organization. They act as a central point of control, helping to ensure that all APIs used by an organization are reliable and secure. API gateways also provide a way to monitor and manage API usage. This can help ensure that APIs are used in a way that does not overload the system or impact the performance of other systems. Additionally, API gateways can help improve APIs’ performance by caching responses and managing traffic.
