Piper (source Control System)
Piper is a centralized version control system used by Google for its internal software development. Originally designed for Linux, it supports Microsoft Windows and macOS since October 2012. Scale Since its founding years Google used a central codebase shared by the developers. For over 10 years Google relied on a single Perforce instance, using proprietary caching for scalability. This mode of operation was kept as Google grew, the need for further scaling led to the development of Piper. Currently, Google's version control "is an extreme case": as of 2016, the repository was storing 86 terabytes of data comprising two billion lines of code in nine million files (two orders of magnitude more than in the Linux kernel repository). 25 thousand developers contributed 16 thousand changes daily, with additional 24 thousand commit operations by bots. Read requests each day are measured in billions. Architecture Piper uses regular Google Cloud storage solutions, originally Bigtabl ...

Centralized Version Control
In software development, distributed version control (also known as distributed revision control) is a form of version control in which the complete codebase, including its full history, is mirrored on every developer's computer. Compared to centralized version control, this enables automatic management Branching (version control), branching and Merge (version control), merging, speeds up most operations (except pushing and fetching), improves the ability to work offline, and does not rely on a single location for backups. Git (software), Git, the world's most popular version control system, is a distributed version control system. In 2010, software development author Joel Spolsky described distributed version control systems as "possibly the biggest advance in software development technology in the [past] ten years". Distributed vs. centralized Distributed version control systems (DVCS) use a peer-to-peer approach to version control, as opposed to the client–server model, clien ...
