In November 2020, AWS released CloudFormation Modules. These are a consistent, accessible, and repeatable way to package resource configurations for inclusion through stack templates. CloudFormation Modules are modular, customizable building blocks that you can use in your stack models to encapsulate common service configurations and best practices. When it comes to securing AWS deployments, a CloudForm

ation template is a groundbreaking technology that has given users more control. AWS CloudFormation Modules are building blocks that teams may use (and reuse) in their CloudFormation models.

Benefits of cloud formation modules

CloudFormation and other AWS-compatible tools have several advantages that speed up and simplify cloud service deployment and management.

1.    Effortless deployment

When you use CloudFormation models to handle how AWS resources are configured and deployed, you can use only one template to deploy several instances of the same resource almost instantly.

2.    Scaling

CloudFormation models are useful for scaling up AWS resources because they mean that you can scale up your environment quickly when the time comes. You’ll be able to add more virtual machine instances or storage space if you keep CloudFormation models on hand.

3.    Continuity

You can add the same configuration over and over again when you use CloudFormation templates to identify and deploy AWS tools. No matter how many instances you make, CloudFormation ensures that your applications and services are consistent and similar.

4.    Shift management and auditing

With CloudFormation’s change monitoring, you’ll be able to see how your AWS services and resources have changed over time without having to sift through logs to piece together the history of changes.

How to create the first cloud formation module?

1. Only a few commands are required to create a new module, beginning with:`cfn init`
2. When asked if you want to build a Resource or a Module, type this followed by m.
3. After that, you’ll be asked to select a module type, which will take the form: ::::::MODULE
4. This will result in:
5. The CloudFormation code is stored in a ‘fragments’ folder, which is initialized with some sample code.
6. A.rpdk-config file that contains module configuration, as the name implies.
7. The rpdk.log file stores the logs provided by CloudFormation commands.

• You just have to describe a CloudFormation prototype from here, including Resources, Parameters, and Outputs as usual.
• It has two parameters: ‘TableArn‘, which specifies which DynamoDB table the policy would enable scan access to, and ‘NamePrefix,’ which gives each policy a distinct name so that it can be distinguished if the module is used several times in the same account.
• Once you’re satisfied with the template, simply run: ‘cfn submit’.

This command verifies the resource scheme before uploading it to CloudFormation. Log in to the AWS Management Console, go to the CloudFormation service, pick Registry from the left menu, and then the Modules tab to verify this.

Ways to increase security via cloud formation modules

Since human error accounts for the majority of security flaws, and repetitive tasks performed by a large number of people can lead to errors, writing code is a safer option than clicking buttons.

1)   Cloud security

AWS is in charge of safeguarding the infrastructure that operates AWS services in the AWS Cloud. As part of the AWS Compliance Programs, third-party auditors assess and check the efficacy of our protection.

2)   Cloud-based security

The AWS service that you use determines your duty. Other considerations, such as the sensitivity of your data, your company’s requirements, and relevant laws and regulations, are also your responsibility.

Conclusion

Manually configuring and deploying AWS tools is a waste of time for your team. Your team will speed up the AWS deployment process by using a platform like CloudFormation. You can create resource configurations once and then deploy them as many times as required. AWS CloudFormation is a cornerstone service that allows businesses to use AWS services to achieve their goals.
