Infrastructure automation is the process of reducing human interaction with IT systems by creating scripts or functions that are repeatable and can be used either by other software or on command.

IT infrastructure automation tools can control IT elements including servers, storage, network elements, and operating systems (OS), with the goal of improving efficiency of IT operations and staff, with the goal of hands-off operation in most environments including both cloud and on-premises elements of hybrid IT environments.

Cloud infrastructure automation tools greatly improve efficiency and speed of workload deployments and can help reduce costs by terminating unused virtual machines (VMs) and reclaim unneeded storage.

Automation is a key component of IT orchestration, of driving IT efficiency, and of enabling an organization’s digital transformation. As IT organizations grow in complexity and size there are a limited number of resources to focus on infrastructure administration. Updates, OS patches, and the ordering, provisioning, configurating, and deploying of systems can present an unmanageable burden for IT were it not for a solid infrastructure automation framework.

Every organization wants efficient, scalable, and reliable IT infrastructure. Automation tools increase agility, enhance employee productivity, and reduce security attack surfaces by eliminating manual errors though standardization of process and governance policies.

Infrastructure automation mostly benefits those tasks that are self-contained, well documented, and tedious to perform manually, for example:

• Provisioning. Infrastructure automation can reduce provisioning time for new VMs, storage, and networking from weeks or months to minutes or hours. This is especially valuable in today’s multi-cloud hybrid IT environments where automation and orchestration work hand in hand to ensure smooth deployment and operation regardless of a workload’s placement.
  
• Cost Reduction. Server and VM sprawl can obfuscate the real costs of a given IT environment. Automation can highlight all cost components of virtual and physical IT infrastructure, enabling department chargebacks and pinpointing anomalies that could mean runaway or forgotten workloads. Without adequate cost containment, management and line of business users often view IT as a liability or cost center, rather than asset or profit center.
• Capacity Planning. Both under-and over-provisioning impact performance organization-wide. Waste can occur due to a lack of standards in deployment or workloads. Infrastructure automation eliminates inconsistencies, thus reducing complexity and increasing standardization across the organization. This can help identify those areas where incorrect provisioning is impacting resource allocation and workload deployment, such as systems with more memory or CPU power than needed for a given workload or workloads.
• VM Sprawl. The simplicity of spinning up new workloads or storage, whether in public or private clouds often leads to VM sprawl, the virtual cousin of server sprawl of years past. Cloud infrastructure automation tools help prevent VM sprawl by identifying workloads that are no longer used, automatically decommissioning those workloads and storage resources. This can help prevent public cloud sticker shock and improve on-premises IT utilization to save significant amounts of money in both capital and operating expenses.

An infrastructure automation framework delivers predictability and repeatability to those processes used for managing IT workload configuration across the organization. This in turn helps IT meet their service level agreements (SLAs) by reducing complexity and freeing up valuable IT resources to focus on business value rather than low level infrastructure management. These factors contribute to increased uptime and consistency while accelerating the deployment of new and changed workloads.

As organizations and infrastructure grow, automation helps teams that are struggling to manage often explosive growth to manage a complex environment with existing staff. Infrastructure automation streamlines ongoing operations such as network management, install/move/add/change (IMAC) of workloads, user access management, storage and data administration, deploying application workloads, troubleshooting, and debugging.

Infrastructure automation offers self-service, multi-cloud provisioning with consistency across clouds. By centralizing policies through templates, automation delivers infrastructure as code (IaC) enabling developers to create VMware templates using JSON/YAML and Git repositories.
