of infrastructure as code and DevOps practices which uses Git as the single source of truth for provisioning infrastructure declaratively. The term GitOps was confined by Weaveworks in 2017 and was primarily ## Benefits of GitOps approach GitOps enables organizations to streamline their infrastructure provisioning and application deployment strategies. This leads to an extensive range of benefits/ ## Ease are validated, and the state is always maintained. When coupled with the declarative approach to provisioning infrastructure, it can drastically reduce errors in the application infrastructure. On top of
