Terraform and Amazon Web Services (AWS) Elastic Kubernetes Service (EKS) offers a powerful solution for managing modern cloud infrastructure. While EKS provides a managed Kubernetes environment, setting up load balancing can be complex. In this article, we’ll explore how to leverage Terraform to streamline the process of creating an AWS EKS cluster and integrating it with an Application Load Balancer (ALB), ensuring a scalable and resilient infrastructure for cloud native applications.

Why Terraform?

Terraform enables developers and operators to define infrastructure configurations in a declarative manner. Here’s why Terraform is the perfect fit for provisioning and managing AWS EKS clusters. Other alternatives would be Cloudformation or AWS CDK but Terraform provides a much cleaner and moduler way to declaratively define infrastructure.

Automation: Terraform automates the provisioning and configuration of resources, reducing manual effort and minimizing the risk of human error.

Consistency: Infrastructure configurations are codified, ensuring consistency across deployments and environments.

Scalability: Terraform’s modular design allows for scalable infrastructure management, supporting growth and evolution over time.

Version Control: Infrastructure code can be versioned and managed using version control systems, promoting collaboration and reproducibility.
