We are excited to announce the official release of DocumentDB—an open-source document database platform and the engine powering the vCore-based Azure Cosmos DB for MongoDB, built on PostgreSQL. NoSQL databases have historically provided cloud-specific solutions without a common standard for interoperability. This has led to a growing demand for an interoperable, portable, and fully supported produ

Ten years ago, Microsoft released the source for MS-DOS 1.25 and 2.0 to the Computer History Museum, and then later republished them for reference purposes. This code holds an important place in history and is a fascinating read of an operating system that was written entirely in 8086 assembly code nearly 45 years ago. Today, in partnership with IBM and in the spirit of open innovation, we’re rele

A new Microsoft video series for developers learning how to script. According to Stack Overflow 2022 Developer Survey, Bash is one of the top 10 most popular technologies. This shouldn’t come as a surprise, given the popularity of using Linux systems with the Bash shell readily installed, across many tech stacks and the cloud. On Azure, more than 50 percent of virtual machine (VM) cores run on Lin

eBPF is a well-known but revolutionary technology—providing programmability, extensibility, and agility. eBPF has been applied to use cases such as denial-of-service protection and observability. Over time, a significant ecosystem of tools, products, and experience has been built up around eBPF. Although support for eBPF was first implemented in the Linux kernel, there has been increasing interest

Following the release of our Developer Preview in June, today we’re announcing an exciting next step as we make the source code of TensorFlow-DirectML, an extension of TensorFlow on Windows, available to the public as an open-source project on GitHub. TensorFlow-DirectML broadens the reach of TensorFlow beyond its traditional Graphics Processing Unit (GPU) support, by enabling high-performance tra

Yesterday, Helm became a graduated project in the Cloud Native Computing Foundation (CNCF), joining a select group of projects that the CNCF recognizes for achieving majority adoption by the cloud-native community. I want to extend congratulations and thanks both to the creators of Helm, as well as to the broader Helm community that has supported, extended, and enabled Helm to reach this significa

Linux container technology has changed the face of computing, but especially distributed computing in publicly rentable servers commonly said to be “the public cloud” (like Microsoft Azure). With containers came tooling – like Docker – and systems that orchestrate potentially millions of them – with Kubernetes becoming the most widely used. Together, they have enabled millions of developers and or

Announcing Distributed Application Runtime (Dapr), an open source project to make it easier for every developer to build microservice applications It is remarkable to see the transformation over the last few years as more and more developers build scalable, cloud native applications, taking advantage of managed services to deploy and run them. With this transformation, microservice architectures h

Announcing the Open Application Model (OAM), an open standard for developing and operating applications on Kubernetes and other platforms Kubernetes has become the leading container orchestration environment. Its success has driven the remarkable growth of Kubernetes services on every public cloud. However, the core resources in Kubernetes like Services and Deployments represent disparate pieces o

Microsoft ♥ Linux – we say that a lot, and we mean it! Today we’re pleased to announce that Microsoft is supporting the addition of Microsoft’s exFAT technology to the Linux kernel. exFAT is the Microsoft-developed file system that’s used in Windows and in many types of storage devices like SD Cards and USB flash drives. It’s why hundreds of millions of storage devices that are formatted using exF

Introducing pg_auto_failover: Open source extension for automated failover and high-availability in PostgreSQL When you’re building a new app, there is a lot you need to focus on. Behind the scenes, there is data stored somewhere, often in a Postgres database. Data is essential, and it needs to be accessible and available. Most of us don’t want to become a database expert early on, and instead foc

Event-driven architectures are a natural evolution of microservices, enabling a flexible and decoupled design, and are increasingly being adopted by enterprise customers. Fully managed serverless offerings like Azure Functions are event–driven by design, but we have been hearing from customers about gaps in these capabilities for solutions based on Kubernetes. Scaling in Kubernetes is reactive, ba
