Infrastructure as code 

The widely quoted benefit of infrastructure as code (IaC) is repeatability and reproducibility. There are a number of components (server, network, security, storage, and so on) in a data center that need to be configured to deploy applications. In cloud environments, there are thousands of such components to be configured. If all is being done manually, the time taken is very huge and error-prone. There are possibilities for the creeping in of configuration differences and drifts. Humans aren't great at undertaking repetitive and manual tasks with 100% accuracy. But machines are very good at doing repetitive, redundant, and routine tasks in scale and speed. If we produce a template and input it into a machine, the machine can execute the template thousand times without any errors. The template-centric approach for infrastructure provisioning, configuration and application deployment gains wider attraction and attention these days. Infrastructure optimization and management...
