Depending on the DevOps model that an organization holds for delivering code into the production environment, considering velocity, complexity, money on the license that multiple tools may require, and block on development teams, it might be interesting to change the strategy to achieve the delivery goals most efficiently. GitOps came to automate and agile the DevOps processes.
By manual infrastructure management, it's meant that when it comes to setting up a new environment for an application, it is necessary to understand all the tools used, which can be, for example, WebSphere, ServiceNow, or UrbanCode.
Most of the time, rollback incidents on software using these tools are complex due to the need for rollback into many different places. The process can be exhausting as it can take a lot of time and also because it's not that simple to version the infrastructure, to set the environment as in previous states.
GitOps is a good solution for versioning infrastructure. It also comes with a new way of implementing infrastructure, which is: using code for it, CI/CD, implementing DevOps best practices, keeping collaboration, etc. For startups and small companies who just want to focus on developers or don't want to hire any more DevOps engineers, that's a way to take advantage of coding skills to embrace the operational side and level up the infrastructure.
Infrastructure as Code tools such as GitOps + Terraform is the perfect combination to use well-known programming languages to build infrastructure and maintain it easily with versioning on Git. Rollbacks are easy to perform and can be made, for example, from a merge.
Some other concepts are still involved with Infrastructure as Code, like the difference between GitOps and ChatOps. I'll leave the link for CTO.ai's blog here in case you want to learn about the difference.
Some examples of what you can do with GitOps:
Use events such as pull requests and merges to trigger pipelines and initiate build or deployment processes.
Versioning infrastructure as code so that you can switch
between different configurations in multiple environments.Enable multiple applications to work with since the configuration will be all in one place.
Overall, there are several benefits in adopting GitOps for teams which the majority is composed of developers who are more familiar with Git and/or YAML. Teams will be able to deliver faster and more efficiently compared to manual processes or multi-tooling processes.
