In this blog post, the authors illustrate how to enhance the automation of cloud provisioning and configuration for Elastic Cloud Enterprise (ECE) using Terraform, building on a previous post that utilized Ansible for deployment. Previously, the provisioning of AWS EC2 instances and security group configuration was done manually, but Terraform now automates these processes by employing infrastructure as code, allowing for version control and programmatic management. The post provides a step-by-step guide on setting up Terraform, defining infrastructure configurations, and running the automation, specifically tailored for AWS but adaptable to other cloud providers. It highlights the simplicity and efficiency of using Terraform to manage cloud infrastructure, reducing the complexity of previous manual steps, and encourages users to experiment with provisioning and managing ECE environments. The setup is designed for a small proof-of-concept or development environment, with pointers for adapting it to full production deployments.
