Faster Builds With Remote Execution and Caching
summary
Describes Google Cloud Remote Build Execution (RBE), an alpha, hosted implementation of the open Remote Execution API that uses Docker image hashes and toolchain descriptions to run Bazel builds and tests at cloud scale. Claims include 80% average build time reduction for TensorFlow (≈50 min → ≈5 min), Android Studio increasing presubmit coverage more than 4x, Angular CI dropping ~1h → 15m, and Absil C++ going 88s → 51s with remote cache and 23s with exec+cache. Advises CI-first onboarding, cache silo key and Docker image hash for hermeticity and permissions.
