Azure Container Apps manages automatic horizontal scaling through declarative scaling rules. We can scale out our container apps based on a variety of different scalers. I recorded a video over the weekend covering how scaling works in Azure Container Apps, what KEDA is and how to set scaling rules within Azure Container Apps, using HTTP and Azure Queue storage scale rules as an example. If you prefer reading rather than watching, continue reading this post. I’ll only be covering the storage queue scaler in this post, so if you want to see how the HTTP scaler works, please watch the video. ...

Azure SQL triggers for Azure Functions came into public preview for C# Functions last month. When you enable Change Tracking on a table in Azure SQL Database, Managed Instance or SQL Server (yes, on-prem SQL Server), you can create a function that will be triggered every time a row is created, updated or deleted. In this article, we’ll dive into the details of SQL Trigger Functions, how Change Tracking works and how we can configure our Functions to listen to SQL Change Tracking. We’ll finish off by discussing how we can monitor how our functions scale as more changes are being processed using the scale controller logs. ...

In my job, I build a lot of samples that I share with customers to show them how things work. A lot of my customers are interested in Azure Container Apps, so I want to be able to provide them with samples with pre-built container images, without having to share the entire application source code as well (especially if I’ve got a bunch of basic microservices, that don’t really need to be included in the sample). ...

I had a bit of time last week to do some Dapr learning, so I started to read the Dapr for .NET Developers e-book that’s available on our documentation (completely free by the way!). In one of the early chapters, the book outlines a tutorial that you can run locally to use service invocation to communicate between to two applications. Running locally is fairly straightforward, so I wanted to deploy the two applications as Container Apps, since it has support for Dapr in the platform. ...

Microsoft Defender for DevOps is a new capability in Defender for Cloud that provides visibility across multiple DevOps environments that you can use to centrally manage DevOps security, strengthen your infrastructure as code and help you prioritize critical issues in code across your pipeline and multiple cloud environments. This feature is currently in preview, and supports GitHub and AzureDevOps (with support for more platforms coming soon). As part of my job at Microsoft, I spend a lot of time helping engineers to use infrastructure as code to provision their resources to Azure, and help them to build pipelines that automates their deployments. In previous roles, I’ve used static code analysis within build pipelines to scan for vulnerabilities in my application code, so naturally I was keen to give this feature a try and apply it to my Bicep code. ...
