Using Java at MSFT

500k JVMs at MSFT as of 2021. Many of these are from Linked, Yammer, Minecraft, and other assets.
Another 500k JVMs for other, non-customer projects.
MSFT is a Java Shop!
Azure Services and internal systems are JVMs.
Android App (over 50 of them) are Java-based and in the GooglePlay store.
BigData Services like Bing and MSN utilize JVMs for infrastructure.

Community engagement through:

Eclipse Foundation
OpenJDK
Adoptium
Spring
GitHub
VSCode

OpenJDK Build

Utilize JDK 11 and 17 LTS.

Platforms includ: Linux, Alpine, macOS, and Windows, all 64 bit.

ContainerImages built on OpenJDK.

Installers developed in OpenJDKs:

MSI, PKG, DEB, and RPM
TAR.GZ and ZIP
Homebrew, WinGet, and SDKMan

MSFT has it's own Build of OpenJDK based on OpenJDK and Adoptium.

Shipped MSFT Build of OpenJDK Java 17.
Minecraft Java Edition is built on this.

Modern Java

Internal partnerts and developers aligned using modern Java (17 LTS).

Azure Platform Services roll-out to Java 17 LTS:

AppService
Functions
Spring Cloud

MSFT has published migration guides on Java 8 -> 11 and 17.

By moving to modern Java (17 LTS):

Cleaner code.
Smaller packages.
Container awareness (kubernetes et al).
Deduped Strings (shrinks XML, JSON apps size).
Improved startup speed.
Memory management improvements e.g. Garbage Collectors for large and small workloads.

MSFT Tools for Java

Playwright: End to end testing for modern web apps.

GitHub Copilot: Coding suggestions provider.

Windows Subsystem for Linux.

VS Code: see aka.ms/java-vscode.

GitHub Actions: Automate workflows.

Maven and Gradle (and Ant): MSFT provides documentation for these.

Building

IntelliJ, Eclipse, and VS Code: All include Azure Integration.

Maven and Gradle support.

GitHub, Jenkins, and Terraform automation for development workflows support.

Build or Migrate Java Apps?

Common Azure tools for building and migrating Java apps (Java SE):

IaaS: Virtual Machines and VMWare Tanzu.
Containers: Azure Kubernetes Service and RedHat OpenShift.
Platform as a Service (PaaS): JBoss EAP, Tomcat, Java SE, and Azure Spring Cloud.

Note: Some support for the above listed services is not there for Java EE flavors.
