From starting in a garage 22 years ago, realestate.com.au has now grown to an ASX 200 company homed in 8 different countries. Join us in the journey of how we created a culture of ownership in this fast-paced digital environment. Ownership has been a key enabler that today allows 60+ engineering teams to build and operate more than 1000 systems in 6 different AWS regions. We’ll share how we’ve evolved from a siloed operations team to multiple on-call cross-functional teams and then how we expanded ownership beyond IT. This story will not only include the cultural changes but also the technology and tools that have helped us along the way: alerting as code, map-style visualization for our software architecture, chatops , etc. Talk presented at the 2019 Sydney AWS Summit.
