AWS CloudFormation vs. HashiCorp Terraform

AWS CloudFormation is well suited for scenarios where all of your resources need to be provisioned on AWS but it is not suited for hybrid cloud deployments. It's very easy for someone new to learn. The level of customization offered as part of the template specifically for AWS services is great. There is also a UI tool where we can drag and drop the services we want and it generates an yaml file which is very easy to use. The visibility of stacks and its resources and one place where we can track and identify the issues in deployment is great.

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.

• 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.

• Error Description upon Failure Needs to be Improved.
• Slow to create, delete or update.
• Need to delete resources manually. It can ask before starting deletion whether to skip those resources or delete them.

• 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.

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

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.

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.

We didn't look into anything else as Cloudformation was "built-in" for AWS, it just kind of made sense to go with that. Terraform was something that we briefly looked into Terraform but decides to stick with Cloudformation because our task was relatively "simple". Apparently if it's a bit more complex, Terraform might be the way to go.

Terraform is the solid leader in the space. It allows you to do more then just provisioning within a pre-existing servers. It is more extensible and has more providers available than it competitors. It is also open source and more adopted by the community then some of the other solutions that are available in the market place.

• It has a positive ROI
• Less time inverted in bugs
• More stable source code

• we are able to deploy our infrastructure in a couple of ours in an automated and repeatable way, before this could take weeks if the work was done manually and was a lot of error prone.
• having the state file, you can see a diff of what things have changed manually out side of Terraform which is a huge plus
• if state file gets corrupted, it is very hard to debug or restore it without an impact or spending hours ..
• writing big scale code can be very challenging and hard to be efficient so it's usable by the whole team
