2. Easy validation of changes <\/strong><\/p>\n\n\n\nCodes are easy to be tested in virtualized environment ( I use \nEVE-NG for the same), you can perform a code review, run a series of \nautomated tests, to ensure that the code does not break the production \nenvironment.<\/p>\n\n\n\n
3. Promotes documentation <\/strong><\/p>\n\n\n\nOld infrastructure has lot of dependency on the administrator for \nthey have the knowledge of dependencies and challenges associated with \nthe infra they manage but sadly in most of the organizations it is not \ndocumented, when the administrator leaves the organization along goes \nthe knowledge with him. The fundamental benefit or IaaC is \ndocumentation, everything is in the source file.<\/p>\n\n\n\n
4. Re-usability <\/strong><\/p>\n\n\n\nThe validated test codes can be deployed in different environments \nwithout major effort involved in re-coding the parameters from zero.<\/p>\n\n\n\n
5. Self-Service Capability<\/strong><\/p>\n\n\n\nAfter the codes are tested thoroughly and hit maturity phase, they \ncan be passed on to the developers to self-provision ( and delete) infra\n as and when needed.<\/p>\n\n\n\n
6. Version Control<\/strong><\/p>\n\n\n\nThis is my personal favorite; version control using Git ( or any \nother similar tool for that matter) brings a lot of agility and \nreliability. All changes in your code is tracked actively in the commit \nlogs and whenever you hit upon a configuration induced issue it can be \ntracked and rolled-back efficiently.<\/p>\n\n\n\n
