| Googler | 5fba619 | 2015-03-17 22:12:05 +0000 | [diff] [blame] | 5 | Bazel is a build tool that builds code quickly and reliably. It is used to build |
| 6 | the majority of Google's software, and thus it has been designed to handle |
| Googler | f346901 | 2015-03-18 15:33:20 +0000 | [diff] [blame] | 7 | build problems present in Google's development environment, including: |
| Han-Wen Nienhuys | d08b27f | 2015-02-25 16:45:20 +0100 | [diff] [blame] | 8 | |
| Googler | 5fba619 | 2015-03-17 22:12:05 +0000 | [diff] [blame] | 9 | * **A massive, shared code repository, in which all software is built from |
| 10 | source.** Bazel has been built for speed, using both caching and parallelism |
| Googler | f346901 | 2015-03-18 15:33:20 +0000 | [diff] [blame] | 11 | to achieve this. Bazel is critical to Google's ability to continue |
| Googler | 5fba619 | 2015-03-17 22:12:05 +0000 | [diff] [blame] | 12 | to scale its software development practices as the company grows. |

| Googler | c9a9f4c | 2015-03-24 15:55:18 +0000 | [diff] [blame] | 14 | * **An emphasis on automated testing and releases.** Bazel has |
| Googler | 5fba619 | 2015-03-17 22:12:05 +0000 | [diff] [blame] | 15 | been built for correctness and reproducibility, meaning that a build performed |
| 16 | on a continuous build machine or in a release pipeline will generate |
| Googler | f346901 | 2015-03-18 15:33:20 +0000 | [diff] [blame] | 17 | bitwise-identical outputs to those generated on a developer's machine. |
| Googler | 5fba619 | 2015-03-17 22:12:05 +0000 | [diff] [blame] | 18 | |
| Googler | f346901 | 2015-03-18 15:33:20 +0000 | [diff] [blame] | 19 | * **Language and platform diversity.** Bazel's architecture is general enough to |
| Googler | 5fba619 | 2015-03-17 22:12:05 +0000 | [diff] [blame] | 20 | support many different programming languages within Google, and can be |
| 21 | used to build both client and server software targeting multiple |
| 22 | architectures from the same underlying codebase. |
