Eliminate LLM Cold starts: Load models up to 6x Faster with Azure Blob Storage and Run:AI Model Streamer
Stop paying for idle GPUs while model weights copy to disk. Stream them straight into GPU memory instead with Run:AI Streamer from Azure Blob Storage. The Problem: Every Cold Start Costs You More Than Money GPU compute is among the most expensive cloud infrastructure, and every second a GPU is allocated but unavailable for serving is real money lost. The cost also goes beyond your Azure bill: slow cold starts can delay responses, stress SLAs, and degrade user experience during traffic spikes, when users need capacity most. In many conventional inference deployments, a cold start triggered by auto-scalin...
Exponential backoff and circuit breaker for Service Bus-triggered Azure Functions
Use exponential backoff and circuit breaker patterns in Azure Functions with Service Bus SDK bindings. Control retry storms, protect dependencies, and degrade gracefully under transient failures.

Least privilege AI agents: A new azd template from Curity and Microsoft
If you ever built an AI agent demo, you probably had this moment. Everything works: the agent interprets natural language, calls the right tools, and returns the right data. Then you start designing for the real users of the app. You think about data boundaries: what if someone tries to get data they're not supposed to see? For example, imagine a customer support app where users can say "give me a markdown report on the last three months of stock transactions and the value of my portfolio." Then an agent does the work. First, you need to design for security so the agent doesn't commingle data from separate cus...

The problem: All-or-nothing batch processing in Azure Service Bus
Azure Functions lets you settle each Service Bus message on its own within a batch. Complete, abandon, dead-letter, or defer messages one by one to avoid duplicate processing and handle errors with precision.
