LY Corporation, the Japanese tech giant formed by the merger of Yahoo! Japan and LINE, is overhauling its cloud infrastructure. To resolve difficulties caused by heavy customizations, the company is consolidating its sprawling network of over 160 OpenStack clusters into a single, streamlined cloud called "Flava." This new architecture will prioritize staying aligned with upstream OpenStack versions to ensure easier upgrades and improved security. The strategy focuses on three pillars: pursuing statelessness, implementing application-driven availability, and enabling faster recovery through Infrastructure as Code. By minimizing custom patches and embracing automation, LY Corp aims to manage its massive user base of 300 million people more efficiently while addressing previous security and privacy concerns.

This blog post compares Ansible and Terraform, two popular tools in the DevOps world, and discusses how they can be used together for a more efficient and comprehensive approach to infrastructure management. It also includes a video walk-through and requirements for a demo example where Terraform and Ansible are combined to create an AWS EC2 instance and deploy a Docker engine on it with Ansible, followed by launching a Jenkins container.
