Amazon Web Services (AWS) provides a robust platform for managing virtual services and resources. However, as you scale up, you may find yourself dealing with multiple AWS accounts across different regions. This is where CloudFormation StackSets come into play. AWS CloudFormation provides a common language for you to manage and provision AWS resources. It allows you to use infrastructure as code and automate your resource deployments. The CloudFormation StackSets extend this functionality to multiple accounts and areas. In this article, you will learn how you can use AWS CloudFormation StackSets to manage multiple AWS accounts effectively.
Understanding AWS CloudFormation StackSets
Before delving into how you can use AWS CloudFormation StackSets to manage your accounts, it is crucial to understand what they are and how they function. AWS CloudFormation StackSets is a feature of CloudFormation that enables you to create, update, or delete stacks across multiple accounts and regions with a single operation. This feature allows you to manage resources across your organization in a centralized manner.

A StackSet is essentially a container for stacks. It lets you deploy the same stack of resources across different accounts and regions. For example, you may need to deploy a set of EC2 instances across multiple regions and accounts. With StackSets, you can do this in one go, rather than going to each account and region and deploying the stack manually.
AWS CloudFormation StackSets can be a significant time-saver, especially when managing multiple accounts and regions. With these, you have more control over your deployments and can ensure that your resources are uniformly deployed across all your AWS accounts.

Setting Up AWS CloudFormation StackSets
Setting up AWS CloudFormation StackSets involves several steps. These include setting up AWS Organizations, configuring IAM roles, and creating a StackSet template.
First, you need to enable AWS Organizations if you haven’t already. AWS Organizations allows you to centrally manage and enforce policies across your accounts. With AWS Organizations, you can create accounts, invite and manage invitations, and apply policies to your accounts.
Next, you need to set up IAM roles for StackSets. IAM stands for Identity and Access Management, which is a web service that helps you securely control access to AWS services and resources. These IAM roles are necessary for StackSets to perform actions on your behalf.
Finally, you need to create a StackSet template. This is a JSON or YAML-formatted text file that describes both the resources you need and the properties for those resources. This template will be used when you create your StackSet.
Deploying StackSets across Multiple AWS Accounts
Once your setup is complete, it’s time to deploy your StackSets. Deploying StackSets across multiple AWS accounts allows you to manage your resources in a streamlined way.
To deploy a StackSet, you use the AWS Management Console, AWS CLI, or SDKs. You specify the StackSet template, the accounts and regions you want to deploy to, and any parameters that the template requires. Then, AWS CloudFormation takes care of the deployment for you.
When you create a StackSet, AWS CloudFormation uses the information in the StackSet template to create a stack in each specified account and region. It then continually manages those stacks for you, ensuring that they match the StackSet template.
Managing StackSets in AWS
Once you’ve deployed your StackSets, you need to manage them effectively. This involves updating your StackSets when necessary and tracking the deployment status of your StackSets.
When you update a StackSet, AWS CloudFormation updates the stacks in the accounts and regions that you specify. It will update the stacks in the same order that you specified when you created the StackSet.
To track the status of your StackSet deployments, you can use the AWS Management Console, AWS CLI, or SDKs. You can see which stacks were successfully created or updated and which ones failed. This allows you to monitor your deployments and ensure that your resources are deployed consistently across your AWS accounts and regions.
AWS CloudFormation StackSets are a powerful feature for managing resources across multiple AWS accounts and regions. By understanding these, setting them up, deploying, and managing them effectively, you can streamline your resource management and ensure that your deployments are consistent across your organization.
Effectively Automating Deployments using CloudFormation StackSets
Automating deployments with AWS CloudFormation StackSets affords you more time to focus on other essential aspects of your business. It is a strategy that simplifies the management of your resources across multiple AWS accounts and regions.
The automation process involves creating a StackSet, which allows you to create, update or delete stack instances. A stack instance refers to a stack in a specific account and region. You can create a stack instance by defining where (AWS account) and in which region you want your AWS resources to be created or configured.
When creating a StackSet, you start by choosing a name for it, specifying the AWS CloudFormation template that defines your stack, and inputting any necessary parameters. You then define deployment options, including the AWS accounts and regions where you want the stack instances to be created.
AWS CloudFormation StackSets offers two types of permissions models: service managed and self-managed permissions. With service managed permissions, AWS CloudFormation takes care of the necessary permissions for you. This is an excellent option for those who prefer a hands-off approach. On the other hand, with self-managed permissions, you manually create and manage the AWS IAM roles needed in your member accounts.
After setting up the deployment options, you can then set deployment preferences. These options let you specify how AWS CloudFormation handles failure during stack creation and whether to roll back on failure. You can also set the maximum number of accounts where AWS CloudFormation can operate concurrently.
Effectively managing multiple AWS accounts across different regions can be a challenging task. But with AWS CloudFormation StackSets, you can simplify and enhance your resource management process. By creating a StackSet, you can ensure that your resources are uniformly deployed across all your AWS accounts and regions.
The setup process for AWS CloudFormation StackSets, which includes enabling AWS Organizations, configuring AWS IAM roles, and creating a StackSet template, may seem daunting at first. However, once completed, the benefits are substantial. You get to have a centralized system that ensures uniform deployments across your organization.
Furthermore, you can automate deployments across different accounts and regions, which significantly saves time and reduces the likelihood of human error. The ability to perform updates and track deployment status also enables you to ensure that your resources are consistently deployed across your AWS accounts.
Indeed, AWS CloudFormation StackSets is an incredibly powerful tool for managing resources across multiple AWS accounts and regions. As your business grows, leveraging such a tool can prove to be a game-changer, leading to more efficient resource management and smoother operations. So, explore and make the most out of AWS CloudFormation StackSets today.
