Maintaining control over configurations in intricate IT systems is a significant challenge. Server environments constantly change, with ongoing code releases, infrastructure modifications, and security updates. Many developers prefer managing system configurations instead of relying on IT infrastructure management services and specialized DevOps tools.
While this self-reliant approach is commendable on paper, it can lead to problems as infrastructure becomes more complex. Manually managing various settings across multiple environments becomes hard and time-consuming. This leads to inconsistency between different environments, called “configuration drift.”
Elements such as development and production servers should always be identical. However, they become out of sync, leading to numerous issues. Here, the role of DevOps configuration management tools comes in, which aims to restore alignment across these systems.
