Integrating cloudtamer.io and AWS Control Tower

I'm excited to announce our new integration with AWS Control Tower. We worked with the AWS Control Tower team to support the automatic enrollment of AWS accounts created by cloudtamer.io. This means you can take advantage of AWS Control Tower and cloudtamer.io, without duplicating efforts.

AWS Control Tower 101

AWS Control Tower was first announced at AWS re:Invent in December 2018 to help new customers better set up and manage multi-account AWS environments. Since then, AWS has augmented this free service to allow organizations to bring in existing AWS accounts. The service now includes 40 out-of-the-box mandatory, strongly recommended, and elective guardrails. AWS Control Tower also helps customers configure a Landing Zone architecture and best practices to setup networking, security, and basic authentication across their AWS cloud environment.

How the Integration Works

The process to integrate cloudtamer.io and AWS Control Tower is very simple. First, enable the AWS Control Tower service. Then, deploy our CloudFormation template (available from our Support Center) in your AWS Master Payer account. The template sets up a Lambda function that performs the enrollment. It also sets up a CloudWatch Event Rule that triggers the Lambda function when a new AWS account is created.

The Integration Value

By integrating cloudtamer.io with AWS Control Tower, you can take advantage of consistent VPC configuration, centralized audit and logging via CloudTrail, and Service Control Policies (SCPs) to prevent users from violating key AWS best practices every time a new AWS account is created.

AWS Control Tower also ensures that Config and CloudTrail are enabled by default in every region to allow customers the ability to detect if configuration drift occurs. cloudtamer.io helps extend these AWS Control Tower benefits through our robust API and Cloud Rules library. This gives enterprises complete end-to-end automation of their account creation workflows along with additional policy and account configurations based on industry compliance and organizational standards.

The Integration in Practice

Here's a look at how this integration can be used in the real world.

Let’s say I’m leading the cloud operations team for a small Australian healthcare company. To comply with the Privacy Act of 1988, the company is required to audit all actions that users perform within every AWS account. The company must also ensure that healthcare data is only stored or processed inside of data centers residing within the country.

Once I enable AWS Control Tower, it automatically configures CloudTrail to record all user actions performed within every AWS account to the Log Archive account within the Landing Zone. Since there is currently only one AWS region in Australia (ap-southeast-2 in Sydney), I also need to ensure that S3 cross-region data replication is not allowed to avoid copies of data being stored outside the country. If every AWS account within the company stores healthcare data, the AWS Control Tower “Disallow Cross-Region Replication for Amazon S3 Buckets” Elective Guardrail can be enabled. However, if there are only specific AWS accounts that store healthcare data, I can use cloudtamer.io Cloud Rules to apply a similar policy across the relevant departments and accounts that store healthcare data. This approach gives more flexibility. Plus, I can provide exemptions for just specific roles (i.e., Administrators) to permit modifying the S3 bucket cross-region replication setting.

In addition, I can use cloudtamer.io Cloud Rules to apply IAM policies to the same departments and accounts to enforce the use of the Sydney region for the other AWS services beyond S3 that should be used to process healthcare data.

Going Beyond the Integration

cloudtamer.io offers many ways that customers can expand AWS Control Tower capabilities to further accelerate automation and make their lives easier in the cloud.

For enterprises with a cloud presence that spans multiple AWS payer accounts and regions like GovCloud, C2S, SC2S, or for enterprises using multiple cloud service providers, cloudtamer.io provides a single pane of glass to view, manage, and automate those environments where AWS Control Tower is not yet available.

Additionally, our unified support across the three pillars of cloud governance offers customers a complete solution to meet the requirements of the AWS Governance at Scale framework. Some examples:

  • Account management capabilities allow you to connect one or more of your Active Directory, OpenLDAP, or SAML 2 identity providers to cloudtamer.io to easily access all of your cloud accounts and subscriptions.
  • Budget enforcement capabilities provide proactive ways to visualize and control cloud costs across the variety of workloads running in your cloud.
  • Continuous compliance features provide full 360-degree controls to prevent, detect, report, and remediate cloud security findings.
