Azure SignalR Service

Azure SignalR Service simplifies the process of adding real-time web functionality to applications over HTTP. This real-time functionality allows the service to push content updates to connected clients, such as a single page web or mobile application. As a result, clients are updated without the need to poll the server, or submit new HTTP requests for updates.

What is Azure SignalR Service used for?

Azure SignalR Service has been used in a wide variety of industries, for any application type that requires real-time content updates. Here are some examples where you can use Azure SignalR Service:

• High frequency data updates: gaming, voting, polling, and auctions.
• Dashboards and monitoring: company dashboards, financial market data, instant sales updates, multi-player game leader boards, and IoT monitoring.
• Chat: live chat rooms, chat bots, on-line customer support, real-time shopping assistants, messengers, and in-game chats.
• Real-time location on map: logistic tracking, delivery status tracking, transportation status updates, and GPS apps.
• Real time targeted ads: personalized real time push ads and offers, and interactive ads.
• Collaborative apps: coauthoring, whiteboard apps and team meeting software.
• Push notifications: social networks, email, games, and travel alert.
• Real-time broadcasting: live audio/video broadcasting, live captioning, translating, and events and news broadcasting.
• IoT and connected devices: real-time IoT metrics, remote control, real-time status, and location tracking.
• Automation: real-time triggers from upstream events.

What are the benefits using Azure SignalR Service?

Standard based:

SignalR provides an abstraction over many techniques used for building real-time web applications. WebSockets is the optimal transport, but other techniques like Server-Sent Events (SSE) and Long Polling are used when other options aren’t available. SignalR automatically detects and initializes the appropriate transport based on the features supported on the server and client.

Native ASP.NET Core support:

SignalR Service provides native programming experience with ASP.NET Core and ASP.NET. Developing new SignalR applications with SignalR Service, or migrating from existing SignalR based applications to SignalR Service requires minimal effort. SignalR Service also supports ASP.NET Core’s new feature, Server-side Blazor.

Broad client support:

SignalR Service works with a broad range of clients, such as:

• web and mobile browsers
• desktop apps
• mobile apps
• IoT devices
• game consoles
