Bazel C++ Monorepo and CI/CD Training in Colombo, Sri Lanka

This instructor-led training is designed to enable C++ development, build, and platform engineering teams to effectively use Bazel for large-scale monorepo environments and integrate it into modern automated CI/CD workflows.

The program begins with Bazel fundamentals and progresses toward build optimization, remote caching strategies, enterprise best practices, and CI/CD pipeline integration patterns aligned with real-world C++ development environments.

Important Note on Tooling:
This training is delivered using open-source and free tool editions. Enterprise-scale capabilities such as distributed execution, high-availability caching, and production-grade artifact management are covered through architectural discussions and demonstration setups without requiring paid licenses.

The course emphasizes practical exercises, real-world C++ examples, and flexible implementation scenarios to ensure immediate applicability.
