To understand the importance of Infrastructure as code approach lets first understand what is Infrastructure as code or IaC

Rise of IaC:

Traditionally the virtual datacenters (Virtualization) say on VMware was provisioned using a management portal where an administrator logs in to the system and from the GUI provision all the required components (VM’s, Network, Storage, etc.) which could consume ranging from few days to months depending upon the Infrastructure size. As we are making the transition towards Cloud where the majority of the things are API driven and mostly infrastructure can be provisioned within a few hours compared to the traditional approach explained above.
