Infra-Provisioning
-
Creating Infrastructure for the application.
-
Sample Application Architecture
-
To realize architecture like the one above, a difficult manual work has to be performed.
-
If there is a tool which can help in creating architectures like above, it would be better. To this tool you need to describe your architecture.
-
The other challenge is where to create this architecture. Because each virtualization env has different tools
- AWS => Cloud Formation
- AZURE => ARM Templates
- Google => Template (Deployment Manager)
- VMWare => VMWare SDK
-
Advantage of Packer/Terraform is they work on almost all the virtualization platforms
