 # What is Azure Web PubSub service?
 
 Azure Web PubSub Service makes it easy to build web applications where server and clients need to exchange data in real-time. Real-time data exchange is the bedrock of certain time-sensitive apps developers build and maintain. Developers have used the service in a variety of applications and industries, for example, in chat apps, real-time dashboards, multi-player games, online auctions, multi-user collaborative apps, location tracking, notifications, and more.

 # Use LiveTry to explore Azure Web PubSub capabilities
 
-**LiveTry** is a browser-based tool that helps you explore Azure Web PubSub’s real-time messaging features — no code or local setup required. With just a few clicks, you can simulate clients, join groups, and send messages using both client-side and server-side APIs.

 This guide walks you through two common messaging scenarios in LiveTry, while helping you understand important concepts like **connections**, **groups**, and **messages**.

 Before getting started, here’s a quick refresher on core Azure Web PubSub concepts that you’ll interact with in LiveTry:
 
-- **Hub**: A logical unit used to isolate and organize messaging logic. In LiveTry, all simulated clients connect to the hub you define on the **Server** tab. Because LiveTry uses your production resource, we recommend specifying a test hub name that doesn’t overlap with your production traffic.

 - **Connection**: A persistent WebSocket connection between a client and the Azure Web PubSub service.
 - **Group**: A server-managed subset of connections. Messages sent to a group are delivered only to the connections within that group.
 - **Messages**: The payloads exchanged between clients and the service. Messages can be broadcast to all, targeted to groups, or directed to individual connections.

 4. Assign each client to a group (for example, `group1`).  
 5. Under the **Server** tab in the "Publish messages" section, select **Send to group**.  
 6. Enter the group name (`group1`), a sample message, and invoke the `sendToGroup` API.  
 7. Switch to the **Client** tab and observe the message appear in each client's message log.
 
 ### What you’re learning
-You’re simulating a backend sending messages to a group of clients using RESTful APIs. LiveTry demonstrates how server-to-group communication works without needing to deploy a backend. Azure Web PubSub also provides server SDKs for C#, JavaScript, Java, and Python.

 Try repeating the steps with multiple clients to visualize message broadcasting in action. LiveTry supports up to 5 concurrent simulated clients.
