Modern application infrastructure is being transformed by containers. The question is: How do you get started? Understanding what problems containers, Docker, and Kubernetes solve is essential if you want to build modern cloud-native apps or if you want to modernize your existing legacy applications. In this post, we’ll go through what they are and how Read more
With the release of Terraform 0.12, we can improve the configuration of our infrastructure resources that are using the Azure Terraform Resource Provider. In this post, we will discuss how we can use Terraform 0.12 to organize, configure, and deploy resources to Azure. What is Terraform 0.12? Terraform is an open source tool that uses Read more
Today, we rely on our everyday services to be delivered digitally and expect the experience to be instant. In order for customer-facing applications to respond to users in 100ms, you need a high-performance database capable of handling a variety of application scenarios at the lowest complexity and cost, with uncompromising performance. Redis is the world’s Read more
In our last post, Daniel Semedo and I provided an overview of how to add automated performance quality gates using a performance specification file, as defined in the open source project Keptn Pitometer. In this post, I’ll explain the steps required to add a performance quality gate to your Azure DevOps pipelines for both DevOps “Multi-Stage” and “Classic” pipelines using Keptn Pitometer. Step 1: Read more
I’m a developer and I’ll admit it, I’m learning Kubernetes. I’ve been developing web applications now for more than 20 years; however, the past two years I’ve moved to working with microservices applications. Originally the microservices were web sites on multiple virtual machines. Last year we started moving towards containers to achieve a higher density Read more
This blog dives into monitoring-as-code ad adding automated performance quality gates into your software delivery pipelines. We’ll walk through examples using a web microservice app and an Azure function app that we developed as open source services that help you qualify the overall performance and quality of applications. Both services utilize the Keptn Pitometer open Read more
Honeycomb is a tool for introspecting and interrogating your production systems. It’s a new type of tool, designed to infuse observability across platforms, microservices, serverless apps, and increasingly complex systems, as well as all the way down to individual customers. I had a chance to catch up with Emily Nakashima, our Director of Engineering at Read more
What is a secret In this blog, we will show you how HashiCorp Vault can help you manage and eliminate secrets sprawl in Azure and your broader organization in general. Before we dive into defining what secret sprawl is, however, it’s good to understand what we define as a secret. A secret is usually one Read more
Prior to March 2019 we, the JUnit team, used various continuous integration (CI) services to perform CI checks, from a self-managed Jenkins instance on CloudBees to a Travis CI and AppVeyor setup. Managing three different setups was not ideal, so the team reduced the CI services used to two: Travis for Linux and Mac builds Read more
In recent years, many developers have discovered the power of distributed tracing for debugging regressions and performance issues in their backend systems, especially for those of us with complex microservices architectures. But in many organizations, our most complex code may not be server-side code — it’s just as likely to be running client-side in a Read more
The service mesh may sound complex, but at its heart, it’s a very simple idea: a set of network proxies that transparently run alongside microservices, implementing reliability, observability, and security features by measuring and manipulating inter-service (“east-west”) traffic. Led by open source projects such as Linkerd, the service mesh model is increasingly popular because it Read more
Python is a great language for building web apps, and Django is one of the most popular frameworks. It lets developers create web apps fast, including modern RESTful APIs, with security and scalability in mind. I’ve been using Visual Studio Code and Azure for a while and was invited to share my experiences at Microsoft’s Read more
