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…

Many of the most exciting experiences we’re beginning to rely on every day are powered by AI; whether it’s conversational assistants, personalized recommendations or code generation, these experiences are powered by inference systems and intelligent agents. Behind the scenes, developers offload complex decisions, automate tasks, and compose intelligent applications using large language models and tool execution flows. Together, these AI-powered primitives are becoming a key complement to traditional application development, enabling a new wave of developer capabilities. At Salesforce, we are helping our customers bring their agentic strategy to life with Heroku, Agentforce, and Data Cloud. These powerful products allow…

Agents hold immense power, but their true potential shines when they connect to the real world, fetching data, triggering actions, or leveraging external tools. The Model Context Protocol (MCP) offers a standardized way for AI agents to do this. MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools. – official MCP website Heroku Managed Inference…

Logging is the unsung hero of enterprise operations—quietly saving the day, one log line at a time. Imagine trying to maintain successful applications without knowing what’s happening inside them. This would be like flying a plane blindfolded at night, in a storm, with no instruments. Spoiler alert: Neither scenario would end well! Today’s distributed systems are massively complex. To develop and maintain them properly, your ability to capture, analyze, and act on log data becomes essential. You need good logging for the critical insights to help you: Diagnose and troubleshoot issues Rightsize cloud resources Ensure security In this post, we’ll…

Generative AI has been one incredible tool to improve my productivity not only for work but for personal projects too. I use it every day, from generating stories and images for my online role playing games to solving code and engineering problems and building awesome demos. Lately I’ve leaned into Cursor as my go‑to AI coding companion. Its inline suggestions and quick edits keep me moving without context‑switching. Connecting Cursor to my apps through the Heroku MCP Server lets me perform actions like deploying or scaling, without leaving my code editor, making AI a first class citizen in the Heroku…
