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
