Web Application Routing on AKS

2022-11-16 5 min read Azure Kubernetes NGINX Ingress
Exposing your web applications on Azure Kubernetes Service (AKS) has gotten a little bit easier. In this post, I will cover the new Web Application Routing feature for AKS and discuss reasons why you may want to implement it within your cluster. Exposing your app You have a lot of options when it comes to exposing your application Pods to the world. If you’re using a managed-Kubernetes service in the cloud, you could deploy a Service and set the type to LoadBalancer and your cloud provider will provision one with a public IP. Continue reading

Deploying ARM64 workloads to AKS

2022-11-02 6 min read Azure Kubernetes ARM64 Docker
You might have heard by now that Azure has partnered with Ampere to bring ARM-based processors for virtual machines on Azure. This is super exciting as it gives you an opportunity to deploy workloads on highly performant and power efficient virtual machines and these characteristics ultimately result in excellent price-performance (lower costs 🥳) So… are you ready to deploy your workloads to ARM64 node pools on AKS? I sure wasn’t when attempting to deploy the azure-voting-app-redis application to my cluster. Continue reading

Sharing Bicep Modules with Azure Container Registry

2022-10-11 14 min read Azure Bicep
One of the things I do as a Cloud Native Advocate at Microsoft is build end-to-end lab scenarios in the https://aka.ms/oss-labs repo. Most of the demo scenarios we aim to cover is in and around the container space and a majority of the labs uses Azure Bicep to declaratively provision Azure infrastructure. As more labs get spun up, there is a potential for redundant Bicep code. You might have already guessed, there’s a need for re-usable code to spin up AKS clusters. Continue reading

Autoscaling Azure Container Apps

2022-09-11 6 min read Azure Containers Scalability
So, what makes Azure Container Apps “serverless”? Today we are going to focus on what makes Azure Container Apps (ACA) a “serverless” offering. But what does the term “serverless” really mean? As much as we’d like to think there aren’t any servers involved, that is certainly not the case. In general, “serverless” means that most (if not all) server maintenance has been abstracted away from you. With serverless, you don’t spend any time managing and patching servers. Continue reading

Microservices Communications with Azure Container Apps

2022-09-10 7 min read Azure Containers Microservices
Introduction In yesterday’s #ServerlessSeptember post, we learned what the Azure Container Apps (ACA) service is and the problems it aims to solve. It is considered to be a Container-as-a-Service platform since much of the complex implementation details of running a Kubernetes cluster is managed for you. Some of the use cases for ACA include event-driven processing jobs and background tasks, but this article will focus on hosting microservices, and how they can communicate with each other within the ACA service. Continue reading

Monitoring Azure Container Apps With Azure Managed Grafana

The Azure Monitor team has announced the general availability of the Azure Managed Grafana (AMG) service. As part of the announcement, they also announced the availability of curated Grafana dashboards for various Azure services including Azure Container Apps 🎉 Grafana is very popular within the Cloud Native community and it seems natural to use it for Azure Container Apps (ACA) observability. In this post, I will walk you through provisioning the ACA and AMG resources using the Terraform AzAPI provider and show you how easy it is to import the ACA dashboards into your AMG instance.

Securely connect to your Azure Linux Virtual Machine with Tailscale SSH

2022-08-12 13 min read Azure Virtual Machines Linux
Being on the Cloud Advocate team at Microsoft, we’re always looking to empower every developer to achieve more on Azure. One way of doing this is by bringing you hands-on content to deliver end-to-end scenarios using cloud-native and open source technologies. My colleague on the Cloud Native team, Aaron Wislang has been cooking up a bunch of labs in our Azure Open Source Labs repo and one area we’ve been collaborating on is within the Azure Linux VM space.
