In the blog post by Mike Barretta, the process of automating the installation of Elastic Cloud Enterprise (ECE) on AWS using Ansible is detailed. Barretta, a newcomer to Ansible, outlines the steps for setting up a small ECE environment, suitable for a proof of concept, testing, or a small production cluster. The process involves creating a security group, launching three EC2 instances across different availability zones, and installing Ansible on the user's machine. The post guides readers through downloading the ECE Ansible role, setting up an Ansible project, creating an inventory, and writing a playbook to deploy and configure ECE. Barretta emphasizes the ease of using Ansible for this purpose, despite his initial unfamiliarity, and concludes by celebrating the successful setup of a three-node, three-zone ECE environment. Readers are encouraged to explore their new setup and potentially deploy Elasticsearch clusters using ECE.
