Quick Answer: Does API Gateway Do Load Balancing?

Does API need gateway?

An API gateway provides a single, unified API entry point across one or more internal APIs.

They typically layer rate limiting and security as well.

Is Load Balancer a gateway?

Gateway Load Balancer – How It Works Gateway Load Balancer combines a transparent network gateway (that is, a single entry and exit point for all traffic) and a load balancer that distributes traffic and scales your virtual appliances with the demand.

Is AWS API gateway highly available?

Amazon API Gateway provides a highly scalable solution to create and publish RESTful and WebSocket APIs.

What is Load Balancer in AWS?

What is a balance loader?

Load balancing refers to efficiently distributing incoming network traffic across a group of backend servers, also known as a server farm or server pool. … In this manner, a load balancer performs the following functions: Distributes client requests or network load efficiently across multiple servers.

Does AWS API gateway do load balancing?

API Gateway can manage and balance out network traffic just as a Load Balancer, just in a different way. Instead of distributing requests evenly to a set of backend resources (e.g. a cluster of servers), an API Gateway can be configured to direct requests to specific resources based on the endpoints being requested.

What if API gateway is down?

Performance and Availability both. In an enterprise microservice setting, each service has their own SLAs. But, with API Gateway in between, your SLA is now multiplied with that of the API Gateway. … If the gateway goes down, so is your service.

Is API gateway A Microservice?

An API Gateway is a server that is the single entry point into the system. … The API Gateway will often handle a request by invoking multiple microservices and aggregating the results. It can translate between web protocols such as HTTP and WebSocket and web‑unfriendly protocols that are used internally.
