Infrastructure as Code Explained: Infrastructure as Code, or IaC, is a method of writing and deploying machine-readable definition files that generate service components, usually in an automated fashion, that supports the delivery of business systems and IT-enabled processes. Infrastructure as Code helps IT operations teams manage and provision IT infrastructure automatically through code without relying on manual processes. Therefore, IaC is often described as programmable or automatized infrastructure. Infrastructure as Code can be applied to the entire IT landscape but it is especially critical for cloud computing, Infrastructure as a Services (IaaS), and DevOps. DevOps requires agile work processes and automated workflows which can only be achieved through the assurance of readily available IT Infrastructure – which is needed to run and test the developed code. This can only happen within an automated workflow.
