Terraform

8 because it's currently best-in-class and is completely essential to use in contrast to not expressing your infrastructure as code. That said, new contenders are nipping at its heels, and I expect stronger tools to emerge in the coming years. Hopefully the Terraform team is able to keep pace.

IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control

Pros

Terraform

  • Terraform is cloud agnostic. Just select the suitable provider for the cloud and it will do the job.
  • Templating is possible to make the Terraform templates reusable.
  • Variables can be created to make the templates generic so that it can be reused for different environments or resources.

IBM Rational ClearCase

  • Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
  • Rational ClearCase handles parallel development of many dependent applications really well.
  • The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.

Cons

Terraform

  • The errors generated by the plan and preview commands are pretty cryptic, it can be hard for newcomers to the scripting language to understand how to address problems.
  • Access controls around workspaces is limited which makes it harder to secure reduce the scope of teams ability.
  • Analytics around user usage, applies and plans would be helpful for managemenet.

  • Extremely buggy.
  • Sometimes the repository gets locked for no reason.
  • Slow.

Usability

Terraform

Terraform 8.0
Based on 1 answer
I love Terraform and I think it has done some great things for people that are working to automate their provisioning processes and also for those that are in the process of moving to the cloud or managing cloud resources. There are some quirks to HCL that take a little bit of getting used to and give picking up Terraform a little bit of a learning curve, thus the rating

Performance

Terraform

Terraform 9.4
Based on 6 answers
Terraform's performance is quite amazing when it comes to deployment of resources in AWS. Of course, the deployment times depend on various parameters like the number of resources to deploy and different regions to deploy. Terraform cannot control that. The only minor drawback probably shows up when a terraform job is terminated mid way. Then in many cases, time-consuming manual cleanup is required.

Support Rating

Terraform

Terraform 7.0
Based on 9 answers
I have yet to have an opportunity to reach out directly to HashiCorp for support on Terraform. However, I have spent a great deal of time considering their documentation as I use the tool. This opinion is based solely on that.I find the Terraform documentation to have great breadth but lacking in depth in many areas. I appreciate that all of the tool's resources have an entry in the docs but often the examples are lacking. Often, the examples provided are very basic and prompt additional exploration. Also, the links in the documentation often link back to the same page where one might expect to be linked to a different source with additional information.

Alternatives Considered

Terraform

Terraform is a tool that is particularly well suited to managing infrastructure specifically. It brings "Infrastructure-as-code" to a level that hasn't been achieved with either Puppet or CloudFormation. The former is more accurately aimed at managing the deployment of code on an instance, managing dependencies and configuration files. The latter can manage infrastructure, but is AWS specific, and does not handle company wide infrastructure well nor does it provide a simple way to maintain a history or implement a code review process (ala pull requests). Terraform can start managing individual pieces of infrastructure, and gradually grow to encompass your entire infrastructure stack as needs require. It can refer to existing infrastructure without exerting control over that infrastructure, and being a text based tool, is amenable diffs, source control, and code reviews. It plays particularly well with Kubernetes, as you can use Terraform to stand up the infrastructure that Kubernetes runs on, and manage the permissions that Kubernetes apps require

If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.

Return on Investment

Terraform

  • Our deployments are more reliable. This way we avoid having unexpected outages due to misconfiguration performed manually.
  • Agility. While doing this using our previous way, we used to spend hours to deploy a new environment. With Terraform it is just a few minutes.
  • Better control! We can track every single change in our environment by our control versioning system.

IBM Rational ClearCase

  • Managed code versioning for many years.
  • Only one person can edit code at a time - slows processing down.
  • IBM is an expensive product to support.
