When you create your AWS CDK and deploy your stack - AWS CDK ultimately converts your code as CloudFormation stacks. But that is outside the scope of this article. There are few other tools available in market outside of AWS - Terraform, Pulumi etc. Note: Please note that we've restricted our discussion to IaC tools available natively within AWS. AWS CDK will fill-in sensible defaults so that you don't need to worry about all nitty gritty details. It is easier to create your infrastructure with lesser lines of code.

The problems that we encountered in CloudFormation is resolved in AWS CDK. You can define your cloud resources using your favourite programming language. As you know, this might be error-prone as one may forget to update the value of a particular parameter.

Not repeatable: If you want to create similar set of resources with different parameters - you might have to do lot of "copy-paste" in your YAML file and change the parameter values.

Sometimes, it is better to have some sensible defaults

Explicitness: You might have to give all parameters explicitly to create AWS resource.

For example, for creating a serverless web application - you might have to write hundreds of lines of YAML.

Lengthy: Even though CloudFormation is easy to understand, the file that we have to create will be lengthy.

There are few problems with CloudFormation: It is well supported and is easy to understand. You can express your code in YAML or JSON format.

Not repeatable: For example, if you want to create similar set of resources for 5 to 10 times in different regions - you might have to repeat the same task again and again.ĬloudFormation is one of IaC tools available in AWS ecosystem.

Lack of review: As your infrastructure is not expressed as code - it is difficult for your peer to review.

It is highly possible for someone to make mistake over a period of time.

Error prone : Creating resources by hand is error-prone.

If you're creating resources manually, below are some of the problems that you might face Infrastructure as Code(IaC) is nothing but having desired state of your infrastructure in the form of code. But, it is highly recommended to use any Infrastructure as Code(IaC) as solution. Yes, you can use AWS console to create AWS resources. Manually creating resources using AWS console: There are few options to provision AWS cloud resources. If you prefer Python, you can refer to CDK with python tutorial here. In this tutorial, we're going to use Typescript. At the time of this writing, AWS CDK supports Typescript, Javascript, Python, C# and Java.
