The Advantages of AWS Control Tower

The challenge a growing number of companies face is how to manage cloud governance across an economic ecosystem comprised of hundreds of teams, each with hundreds of different workloads.

The goal of AWS Control Tower is to provide IT admins with a service control console that lets them manage security compliance easily while simultaneously ensuring that best practices are followed by developers and other employees.

Companies need to ensure that applications and teams are secure from day one of their cloud migration. Control Tower helps them reach this goal by automating security compliance and enforcement of best practices from the outset of the migration process.

What AWS Control Tower offers:

  1. Get teams migrated to the cloud right away.
  2. Give them self-service provisioning access on demand (no two-week wait as a request goes through a workflow ticketing system to gain required approvals).
  3. Make sure you have the correct operational capabilities in place to support continuous monitoring/continuous compliance.

When all the pieces are working together the result is self-service governance at scale. Control Tower automates the provisioning process so that teams can work faster yet in a managed environment that enforces compliance automatically. The key is to automate the enforcement of best practices.

Advantages of AWS Control Tower for Cloud Governance

It isn’t unusual for a company to spend weeks or months setting up its landing zone for a multi-account AWS environment, but with Control Tower the process is automated using best practice blueprints customized to the needs of your organization. Now a landing zone can be configured in a matter of minutes or hours.

Control Tower also automates changes to access controls as employees join and leave the company. All required backend changes are made automatically to admin and security settings, enabling single sign-ons based on database best practices without the usual heavy lifting. The configurations are continuously monitored and account policy compliance is displayed on a dashboard so development teams aren’t slowed down by waiting for approvals from a central security team.

Control Tower also lets you apply guardrails, which are best-practice policies that can be applied right out of the box for all accounts. Some guardrails are mandatory and enabled by default, while others are optional. Preventive guardrails are usually service control policies that prevent resources from being deployed that don’t comply with policies, while detective guardrails continuously monitor deployed resources to spot noncompliance. Guardrails are translated automatically by Control Tower into granular AWS policies.

Another important Control Tower feature is the concept of a database account factory that automates provisioning of new accounts. All new accounts generated using account factory have specific roles to bootstrap and create them, which allows auditors to access them to prevent abuse and manage the environment footprint.

Control Tower’s dashboard allows the health of the AWS environment to be determined at a glance using visual indicators in conjunction with notifications when automated remediation actions occur. With a single sign-on, you get access to the log archive and audit accounts, which allows the entire cloud trail and all config logs to be sent to a centralized account. Every new account gains all these features the moment it is deployed.

How Control Tower Brings Self-Service to Resource Provisioning

While there are many different approaches that development teams can adopt, they tend to standardize on a handful of languages and stacks, using them for 80 percent of their work. With Control Tower, every new database account that is created gets bootstrapped with the most commonly requested database infrastructure as a self-service service catalog product. This ensures that all the appropriate security ports are disabled and the correct access controls are in place.

One of the greatest advantages Control Tower offers AWS customers is that they pay only for the AWS services they set up using Control Tower. This includes the AWS Service Catalog and other services that are created by default, as well as those supporting custom implementations, such as AWS Config rules for enabling detective guardrails. You pay only for the services you use, when you use them, with no upfront commitments.

How Mission Can Help

The self-service consumption model that AWS makes possible has fundamentally changed the way IT consumes resources. This creates a great deal of agility for companies, but it also presents many challenges, perhaps the greatest of which is cloud sprawl. Companies tend to create a lot of resources and new accounts without being clear about what they’re for and how they fit into the big picture. Companies are squeezed between applying best practices and keeping within their cloud budgets.

By working with Mission, an AWS Premier Consulting Partner, companies are able to realize the many benefits AWS Control Tower as they strive to strike the perfect balance between agility and innovation versus governance and control. Mission is able to leverage Control Tower to implement cloud governance and security guardrails transparently and efficiently.

Perhaps the greatest benefit delivered by AWS Control Tower is the ability to standardize across account provisioning, centralized policy enforcement, and other governance and security requirements. Mission has the skills and knowledge to guide businesses of all sizes through the process of leveraging AWS Control Tower to assure they are able to achieve their cloud-management goals in the most effective and affordable manner possible.

  1. How does the AWS Control Tower handle integration with existing AWS accounts or workloads that were not initially set up under its management?

Integrating existing AWS accounts with AWS Control Tower involves enrolling these accounts under Control Tower's governance. This integration allows previously established accounts to benefit from centralized policy management and security compliance, enhancing overall governance without starting from scratch.

  1. What are the limitations or challenges when using AWS Control Tower for complex, hybrid cloud environments?

When deploying AWS Control Tower in complex, hybrid environments, the primary challenge lies in extending its governance capabilities beyond AWS to manage on-premises resources effectively. This might require leveraging additional AWS services or third-party solutions to achieve a unified governance framework.

  1. Can AWS Control Tower's automated compliance features directly support specific industry standards or regulations, such as GDPR or HIPAA?

AWS Control Tower's automated compliance features are designed to align with AWS best practices, which can aid in meeting specific industry standards or regulations. However, organizations are responsible for configuring these to ensure compliance with standards such as GDPR or HIPAA.
