What is Git?

One of the most popular source control systems available, Git has been around for a very long time. Git is a completely mature and actively maintained open-source project originally developed by Linus Torvalds in 2005. Who is Linus Torvalds? Only the world-famous creator of the Linux operating system kernel. A simply monumental amount of software projects rely on Git for version control. The beauty of Git is it’s a decentralized approach to version control. Having a distributed architecture, it’s an example of a distributed version control system or DVCS. Instead of only having one place for the full version history of the software as is popularly prescribed with once-popular version control systems like CVS or Subversion, or SVN, in Git, every developer’s working copy of the code is also a repository that can contain the full history of all the submitted changes.

The Three Pillars of GitOps: Pipelines, Observability, & Source Control

Weaveworks Cloud & Flux - Git Version Control for Automated Kubernetes Web Server Configuration

According to Alexis Richardson, co-founder/CEO of Weaveworks, and William Denniss, project manager at Google Cloud Platform, GitOps are "modern best practices for high velocity app development using cloud native tools." With GitOps, web server configuration is regarded as code and subject to version control, where Git operates "as a single source of truth for the whole system." GitOps depends on completely automated software delivery pipelines, with 24/7 monitoring and observability "baked into the beginning," where data security is of "critical importance. Everything has to be version controlled and stored in a single source of truth from which you can recover." In Agile development teams, Terraform, Spinnaker, Puppet, & Ansible are currently popular for web server script automation using Git for disk image prints with Docker & Kubernetes on public cloud hosts for CI/CD requirements in project management. Weaveworks has developed a number of cloud platforms that address the software development & web server hosting pipeline holistically such as Weave Cloud, Weave Flux, and integrated AWS container management products. GitOps allows developers to make hundreds of small changes per day to running websites & mobile applications in live production rather than rolling out monolithic upgrades. YAML is used to build declarative infrastructure statements that can be repeated and implemented as standards for cloud network automation. In GitOps, diff alerts & pull requests are managed through decentralized networks of programmers in Agile teams from any office location using Git, increasing management flexibility in hiring and worker productivity times. GitOps has now become standard in web/mobile app development for enterprise corporations, start-up companies, non-profits, government agencies, & SMEs worldwide.
