Automation is really important, and you should be provisioning using Infrastructure as Code tools and automating as much as possible. Automation also makes cloud governance easier. This is because you can track and allocate spend to the right cost centres in your organisation.
If you are using only 1 Public Cloud, we would implement Cloud native tools, as they will be easier to automate than third party tools, as the tooling and API’s are more seamless and integrated. For Multi-Cloud designs we use tools like Azure ARM templates as they work across different clouds and on-premises platforms.
