SignalR makes it easy to add real-time functionality to .NET web applications—things like live chat, instant notifications, or interactive dashboards. But what happens when your app starts to grow? A single server can only take you so far. At some point, you’ll need to scale out. In this post, we’ll walk through what it takes to scale a SignalR app to run across multiple servers. We’ll start with the basics, then show you how to use Redis as a backplane and enable sticky sessions to keep WebSocket connections stable. And we’ll deploy it all to Heroku. If you’re curious about…

Heroku’s commitment to developer productivity shines through in its powerful buildpack system. They handle the heavy lifting of building your app, letting you focus on what matters most: writing code. A prime example is the Heroku Java buildpack, a versatile tool that simplifies deploying Java applications, especially those built with popular frameworks like Spring Boot, Quarkus, and Micronaut. One of the core strengths of Heroku buildpacks is their automatic nature. They intelligently detect your application’s language and framework, fetching the necessary build tools and configuring the Heroku platform to run your app seamlessly.

Update November 7th, 2022: These plans are now generally available. Take a look at our launch announcement post for more information on migration. When we announced Heroku’s Next Chapter last month, we received a lot of feedback from our customers. One of the things that stood out was interest in a middle ground between our retired Heroku free plan and our current Hobby dyno and data plans, a lower-cost option. We’ve also fielded requests to keep a dyno that “sleeps” when not receiving requests, which is an integral feature for non-production apps. Eco Dynos: Free While Sleeping With that in…
