AWS CodeDeploy vs Terraform: What are the differences?
AWS CodeDeploy: Coordinate application deployments to Amazon EC2 instances. AWS CodeDeploy is a service that automates code deployments to Amazon EC2 instances. AWS CodeDeploy makes it easier for you to rapidly release new features, helps you avoid downtime during deployment, and handles the complexity of updating your applications; Terraform: Describe your complete infrastructure as code and build resources across providers. With Terraform, you describe your complete infrastructure as code, even as it spans multiple service providers. Your servers may come from AWS, your DNS may come from CloudFlare, and your database may come from Heroku. Terraform will build all these resources across all these providers in parallel.
AWS CodeDeploy and Terraform are primarily classified as "Deployment as a Service" and "Infrastructure Build" tools respectively.
Some of the features offered by AWS CodeDeploy are:
- AWS CodeDeploy fully automates your code deployments, allowing you to deploy reliably and rapidly
- AWS CodeDeploy helps maximize your application availability by performing rolling updates across your Amazon EC2 instances and tracking application health according to configurable rules
- AWS CodeDeploy allows you to easily launch and track the status of your deployments through the AWS Management Console or the AWS CLI
On the other hand, Terraform provides the following key features:
- Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.
- Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.
- Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.
"Automates code deployments" is the primary reason why developers consider AWS CodeDeploy over the competitors, whereas "Infrastructure as code" was stated as the key factor in picking Terraform.
Terraform is an open source tool with 17.4K GitHub stars and 4.77K GitHub forks. Here's a link to Terraform's open source repository on GitHub.
Instacart, Slack, and Twitch are some of the popular companies that use Terraform, whereas AWS CodeDeploy is used by Adsia, Algorithmia, and indico. Terraform has a broader approval, being mentioned in 490 company stacks & 298 developers stacks; compared to AWS CodeDeploy, which is listed in 57 company stacks and 14 developer stacks.
