Polly is classed as a resilience framework. A resilience framework is a set of libraries that help an application to recover from transient or more extended failures in services or infrastructure upon which it depends. When recovery is not possible, the resilience framework will facilitate graceful degradation of your application.
Polly has been around for many years and has been tried and tested in many applications
Throttling and rate-limiting allow you to prevent abuse of your API and ensure that your API withstands large numbers of calls (including DoS and accidental loops).

JSON Web Tokens is an emerging standard. They are very close to their standardisation.

Then we have a look at the structure of a JSON Web Token, and then we’ll show you how easy it is to create and consume them using the Microsoft DotNet Core development framework.
