One of the imperative architectural concerns is to protect APIs and service endpoints from harmful effects, such as denial of service, cascading failure. or overuse of resources. Rate limiting is a technique to control the rate by which an API or a service is consumed. In a distributed system, no better option exists than to centralize configuring and managing the rate at which consumers can interact with APIs. Only those requests within a defined rate would make it to the API. Any more would raise an HTTP “Many requests” error.
