Infrastructure as Code (IaC) is changing the way that we’re doing things. Some people think that it’s the motorway that we have to follow and be aligned with business, as a resume they want us to be agile.

The arrival of tools such as Ansible, Puppet, SaltStack, and Chef, have enabled sysadmins to maintain modular, automatable infrastructure. This time I would like to introduce the Terraform tool.

Terraform is a provisioning declarative tool that is based on the Infrastructure as Code paradigm. Terraform is a multipurpose composition tool: it composes multiple tiers (SaaS/PaaS/IaaS).

Terraform is not a cloud agnostic tool, but in combination with OpenNebula, it can be amazing. By taking advantage of the template concept it will allow us to deploy vm’s agnostically in different cloud providers, such as AWS, Azure or on premise cloud infrastructure.
