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). With Throttling, you can set a delay on calls after an SLA tier has been exceeded, slowing down the number of requests an API client is making.

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.

NET Microservices Architecture for Containerised NET Applications
I came across this guide as it is an introduction to developing microservices-based applications and managing them using containers. It discusses architectural design and implementation approaches using .NET Core and Docker containers. To make it easier to get started with containers and microservices, the guide focuses on a reference containerized and microservice-based application that you can explore. The sample application is available at the eShopOnContainers GitHub repo.
