With EngFlow Remote Execution, Brave’s Android, Linux, macOS, and Windows Chromium builds are now distributed across a large number of machines – instead of running everything on a single, local machine with sometimes as few as four cores. The EngFlow remote execution cluster executes builds for all platforms on a Linux-based backend consisting of hundreds of cores, cross-compiling when targeting different operating systems or architectures. This simplifies the infrastructure greatly while also saving thousands of dollars. Additionally, using remote execution allows sharing compiled objects between all developers, reducing unnecessary, repetitive building. Builds are also hermetic and reproducible.
