We have separate DevOps processes for different teams. We're implementing agile processes, so we have cells for each product, and each cell has its own DevOps process. This means we have a DevOps process in GitHub, GitLab, and another tool. We have lots of costs and can't share experience between teams.
The idea was to unify everything in one product to ensure that we standardize DevOps practices on the same tool to have better knowledge and expertise and focus on a specific tool.
