The key principles of immutable infrastructure are centered around the idea that infrastructure should be treated as code. This means that any changes to the infrastructure should be made by modifying the code and then redeploying it, rather than making direct changes to the running infrastructure. This ensures that the infrastructure remains consistent and predictable, leading to more reliable deployments.
Immutable infrastructure offers several benefits for deployment consistency. One of the primary advantages is that it eliminates configuration drift, which occurs when the actual configuration of a system deviates from its intended state. With immutable infrastructure, the configuration is defined in code and remains unchanged, thus reducing the risk of configuration drift.
Additionally, immutable infrastructure improves deployment reliability by ensuring that the environment in which the application runs is consistent across all stages of the deployment pipeline. This consistency reduces the likelihood of issues arising due to differences in the underlying infrastructure.
Source code management, also known as version control or revision control, is the practice of tracking and managing changes to source code. It allows multiple developers to work on the same codebase simultaneously, without interfering with each other's work.
