App Center Cloud Build Machines

Each build runs on a separate, clean virtual machine (VM), and no other user has access to the VM. Once the build completes, App Center discards the virtual machine, and all files removed. The artifacts resulting from the build (log files, application files, symbol files) are stored on App Center servers.

Image Changes

App Center now uses the Java Azul OpenJDK

The following Java versions are available on the VM image: 7, 8, 11, 12. Java versions 9 and 10 were deprecated.

Previously, Microsoft hosted Mac machines ran with pre-installed JDKs overloaded with complex licensing, end-user restrictions, and lack of long-term support. With recent image changes, App Center replaced the JDKs with tested, certified, LTS builds of OpenJDK from Azul Systems.

Java developers can now build and run production Java applications using Azul Systems Zulu Enterprise builds of OpenJDK without incurring additional support costs. This new offering is designed to make Microsoft hosted Java builds and deployments worry-free by incorporating quarterly security updates and bug fixes as well as critical out-of-band updates and patches as needed.

Operating System

Builds for iOS and Android apps (including Xamarin and React Native platforms) are run on macOS VMs running the following configuration:

  • OS X 10.14.6 (18G84) Mojave for builds running Xcode 9.4.1 and higher and also for non-Xcode builds
  • OS X 10.13.6 (17G7024) High Sierra for builds running Xcode 9.4 and lower

Builds for UWP apps are run on Hosted Windows Agents.
