Google File System (GFS or GoogleFS, not to be confused with the GFS Linux file system) is a proprietary distributed file system developed by Google to provide efficient, reliable access to data using large clusters of commodity hardware. Google file system was replaced by Colossus in 2010.
Bigtable development began in 2004. [1] It is now used by a number of Google applications, such as Google Analytics, [2] web indexing, [3] MapReduce, which is often used for generating and modifying data stored in Bigtable, [4] Google Maps, [5] Google Books search, "My Search History", Google Earth, Blogger.com, Google Code hosting, YouTube, [6] and Gmail.

CloudStore supports incremental scalability, replication, checksumming for data integrity, client side fail-over and access from C++, Java and Python. There is a FUSE module so that the file system can be mounted on Linux. In September 2007, Kosmix published Kosmosfs as open source. [1] The last commit activity was in 2010.
Google I/O is Google's largest developer event, which is usually held in May at the Shoreline Amphitheatre, Mountain View. Google Summer of Code is a mentoring program to find students for open source projects. In 2016, the program received nearly 18,980 applications. Google Code Jam is an international programming competition.
Developers have read-only access to the file system on App Engine. Applications can use only virtual file systems. App Engine can only execute code called from an HTTP request (scheduled background tasks allow for self-calling HTTP requests). Users may upload arbitrary Python modules, but only if they are pure Python.
Bazel is extensible with the Starlark programming language. [13] Starlark is an embedded language whose syntax is a subset of the Python syntax. However, it doesn't implement many of Python's language features, such as the ability to access the file I/O, in order to avoid extensions that could create side-effects or create build outputs not known to the build system itself.
JAX is a machine learning framework for transforming numerical functions developed by Google with some contributions from Nvidia. [2] [3] [4] It is described as bringing together a modified version of autograd (automatic obtaining of the gradient function through differentiation of a function) and OpenXLA's XLA (Accelerated Linear Algebra).
code.google.com /archive /p /szl / Sawzall is a procedural domain-specific programming language , used by Google to process large numbers of individual log records. Sawzall was first described in 2003, [ 1 ] and the szl runtime was open-sourced in August 2010. [ 2 ]
