realestate.com.au (REA) has partnered with AWS for over 12 years and is privileged to have 60% of the Australian population visiting realestate.com.au every month. They have identified that adopting new services and keeping thousands of stacks healthy is hard work, requiring ingenuity and out-of-the-box thinking to succeed. This session explores how REA leverages infrastructure-as-code at scale using an internal tool called CoPilot. REA-CoPilot reduces costs and enables SysOps Admins to focus on higher-order problems. REA made applying changes across hundreds of multi-generation AWS accounts a breeze. In this session, watch how REA-CoPilot combines Kubernetes Operators and advanced AWS Identity and Access Management (IAM) concepts to take automation to the next level.
