  • Focus on your core business instead of managing infrastructure

    You don't have to provision and maintain servers just because you need real-time features in your solution. SignalR Service is fully managed which makes it easy to add real-time communication functionality to your application. No more worrying about hosting, scalability, or load balancing – it's all handled automatically.

  • Take advantage of the full spectrum of Azure services

    Benefit from everything Azure has to offer! Easily integrate with services such as Azure Functions, Azure App Service, Microsoft Entra ID (formerly Azure Active Directory), Azure Storage, Azure Analytics, Power BI, IoT, AI Services, Machine Learning, and more.

  • Offer Enterprise-grade functionality

    Use the SignalR Service Premium Tier to leverage enterprise capabilities such as auto-scaling, higher SLA, Azure Availability Zone support, and rate limiting. Send advanced metrics to Azure Monitor or integrate with other monitoring solutions.
