What is Amazon EventBridge?

Amazon EventBridge is a serverless event bus service that enables real-time response to state changes in your applications. Using an event bus, it collects data from multiple sources, processes and routes them between other AWS services or external SaaS providers. This simplifies the building of scalable and loosely coupled systems in event-driven architectures.

SignalR

What is SignalR?

SignalR is an open-source library that simplifies adding real-time web functionality to apps. It is integrated into the ASP.NET Core web development stack and provides a mechanism for two-way remote procedure calls between client and server.
