Heroku recently made the next generation platform – Fir – generally available. Fir builds on the strengths of the Cedar generation while introducing a new modern era of developer experience. Fir leverages modern cloud-native technologies to provide a seamless and performant platform.
One of the goals we set out to achieve with Fir is to modernize our platform’s observability architecture. Applications being written today are becoming increasingly more distributed and complex in nature. With this increase in complexity, the need for good observability becomes critical. With solid observability practices in place, it becomes possible to gain deep insights into the internal…

The speed and efficiency of the Go programming language make it popular for backend development. Combine Go with the Gin framework —which offers a fast and minimalistic approach to building web applications—and developers can easily create high-performance APIs and web services. Whether you’re working on a personal project or building a production-ready application, Go and Gin make for an attractive stack perfectly suited for lightweight, scalable web development.
Creating a Go/Gin application might seem straightforward: You write a few routes, connect a database, and spin up a local server. But when it comes to deploying your app, things can get tricky.…

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 what…

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…

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.

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 explore the…
