Which command should a cloud architect use to deploy an IaaS platform after making changes to templates?

The command that a cloud architect should use to deploy an Infrastructure as a Service (IaaS) platform after making changes to templates is "git push." This command is used to upload local repository changes to a remote repository. In the context of deploying an IaaS platform, once the architect has made changes to the configuration templates, these changes need to be shared with the remote repository (which could trigger deployment processes, such as those managed by CI/CD pipelines).

By using "git push," the architect ensures that the updated templates are available in the central repository, allowing the environment management tools (like Terraform or Ansible) to pull the latest configurations and deploy them accordingly. This process integrates code management with deployment, emphasizing the importance of version control in cloud infrastructure management.

In contrast, other options like "git clone" and "git fetch" serve different purposes—cloning is for creating a copy of an entire repository, while fetching updates the local copy with changes from the remote repository without merging them. "git pull" is combination of fetch and merge, but does not involve sending changes back to the remote, which is exactly what is needed in this scenario after modifying the templates. Thus, "git push" is the correct operation to execute
