AWS EKS Security: Best Practices and Tips

What is AWS Elastic Kubernetes Service (EKS) ?

ūüĆü The Amazon Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes service on AWS.ūüĒí

AWS EKS is a managed service that allows you to run Kubernetes clusters on AWS without having to install, operate, or maintain your own Kubernetes control plane. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes enables you to run your applications across multiple nodes, pods, and containers, using a declarative configuration to ensure the desired state of your system. AWS EKS makes it easy to launch and manage Kubernetes clusters on AWS, with features such as automatic scaling, load balancing, networking, security, logging, and monitoring.

AWS EKS is important for cloud-native applications because it provides a consistent and compatible platform for deploying and running your applications on AWS. Cloud-native applications are designed to take advantage of the scalability, reliability, and performance of cloud computing, using microservices, containers, and DevOps practices. AWS EKS enables you to leverage the benefits of Kubernetes, such as portability, flexibility, and resilience, while also integrating with the AWS services and tools that you already use, such as Amazon EC2, Amazon S3, Amazon VPC, AWS IAM, AWS CloudFormation, AWS CloudTrail, and AWS CloudWatch. AWS EKS also supports the Kubernetes ecosystem and community, allowing you to use the same tools and plugins that you use with any other Kubernetes environment.

Data Security & Flexibility

To ensure the safety of sensitive information, you can deploy the solution in an AWS Region that aligns with your data classification requirements. Amazon Macie can be used to quickly identify any sensitive data that may be present in your Amazon S3 buckets.

Automation by leveraging AWS expertise

With the help of next-generation framework using the Cloud Development Kit (CDK) based, Landing Zone Accelerator engine, you can effortlessly create a secure cloud environment perfect for hosting your workloads. This solution will help you consistently maintain

Customer resources focus on learning to ‘operate’ in the cloud

Organizations can save valuable resources and time by using the Landing Zone Accelerator to establish a complaint and improve security posture. This way, they can avoid building and maintaining complex infrastructure and code. With the Landing Zone Accelerator Solution handling governance complexities, customers can focus on what they do best – driving innovation and growth.


It is widely known in highly regulated industries that building a solid foundational environment can take three to 18 months or even longer. This is due to the complexities of obtaining ATOs (Authority to Operate), which involves proving compliance with the security controls. However, this process can be accomplished in days or even minutes with the Landing Zone Accelerator solution. Here are some success stories from satisfied customers who have benefited from this solution.

Innovate through open source model

The AWS Landing Zone Accelerator (LZA) solution is designed to help you integrate security and compliance into your workloads as you grow. It uses CodeBuild to orchestrate each action after the Source stage, running a CDK application that deploys CloudFormation stacks across AWS accounts and Regions.  This approach saves time and effort, ensures consistency, and reduces the risk of errors and misconfigurations.

Foundation for compliance

Over time, the LZA solution may undergo changes or updates while your business requirements and environments evolve. You may also need more controls and capabilities to enhance governance and security posture. The solution (code engine and configuration separation) is designed so that even after a few years, you can use the exact repeatable mechanisms to perform all the required tasks without re-engineering an entirely new system.

Nothing come for free (How Much Will Solution Really Cost?)

Customers are responsible for the cost of the AWS services used while running this solution. As of this revision, the cost for running this solution using the Landing Zone Accelerator on AWS best practices configuration with AWS Control Tower in the US East (N. Virginia) Region within a non-critical sandbox environment with no activity or workloads is approximately $430.22 (USD) each month.

AWS recommends creating a budget through AWS Cost Explorer to help manage costs. Prices are subject to change. For full details, refer to the pricing webpage for each AWS service used in this solution.

The Landing Zone Accelerator on AWS solution may entail a certain cost, but the benefits that come along with it are invaluable. By adopting this solution, you can ensure that your workloads comply with industry standards, which can significantly reduce the time and resources needed to obtain ATO (Authority to Operate) certifications. Additionally, this solution eliminates spending valuable time and effort building a cloud foundation from scratch. This frees up your time to focus on what you do best while the solution takes care of the governance at scale.

Wrap Up!

In conclusion, the Landing Zone Accelerator on AWS offers an invaluable advantage by enabling fast provisioning of new environments tailored to specific governance requirements, all while saving precious time and resources. Its thoughtful design, distinguished by separating code and configuration, ensures long-lasting efficiency. Even in the years to come, you can count on the exact, reliable, repeatable mechanisms to execute essential tasks without needing a complete system revamp. This solution represents a strategic and cost-effective investment, promising substantial savings in time, resources, and finances while empowering you to focus on what truly matters.
