Cons and Pros of API Gateways
Thread ๐Ÿงต๐Ÿ‘‡๐Ÿป
An API gateway is a software layer that sits between an application and a backend service.
It acts as a proxy, routing requests from clients to services.
It can also perform other tasks such as authentication, rate-limiting, and monitoring.
1๏ธโƒฃ PROS
They provide developers with access to the functionality of a subset of architecture in many different ways without ever exposing the endpoints publicly.
Security
API gateway provides a security barrier between your front-end applications and microservices, ensuring that sensitive API endpoints are not exposed.
API is also protected from malicious attacks such as DoS attacks, SQL injections, and other similar attacks that exploit its vulnerabilities.
An API gateway can also handle rate limiting, user access control, and token authorization.
The API gateway does all the heavy lifting regarding routing and formatting responses. It can even handle caching for you.
API gateways can come with monitoring or analytics tools to help developers debug and create scalable infrastructures.
2๏ธโƒฃ CONS
As API gateway is another layer in your app infrastructure, it will act as a single point of failure.
It will also require more configuration from developers because it makes your infrastructure more complex.
It may also affect your API's speed and response time.
It may degrade the performance of the entire API.
