Which automation method is described as beneficial for creating repeated deployments?

The method recognized for creating repeated deployments is Chef deployment. Chef is a configuration management tool that automates the process of managing infrastructure, allowing for efficient and consistent deployment of software and services across multiple environments. This automation is particularly beneficial for organizations that require standardized environments, as it accelerates deployment processes and reduces the potential for human error by ensuring configurations are applied consistently.

With Chef, you can define your infrastructure as code, allowing you to recreate environments quickly and reliably. This is especially useful in a deployment scenario where the same configuration needs to be applied multiple times, ensuring that each deployment adheres to the predefined specifications.

In contrast, other options like ArcGIS Enterprise Builder focus more on streamlining the setup process initially but do not provide the same level of ongoing automation for repeated deployments across various environments. Machine images can help with rapid provisioning but do not inherently manage application configurations or ensure consistent deployment specifications. Manual setup, while sometimes necessary, is the least efficient method for repeatable deployments due to the potential for inconsistencies and the extensive time involved.
