Leans on everything-as-code to stay slim.
Qantas is using infrastructure-as-code and operations-as-code to run at scale in the cloud with a core platform team of just 12.
The airline used the recent AWS Summit in Sydney to reveal some of the practices it has put in place over the five years it has been running cloud-based workloads, and the results that has helped it to reach.
“At any one time at Qantas, we’re running about 4000 instances and that’s a mixture of multiple instance types and multiple operating system types,” Qantas cloud services lead Steven Tyson said.
“To date, we’ve launched about 2.7 million instances and we’ve got a significant spend across hundreds of accounts.”
Tyson said Qantas used a blue-green architectural approach to get code changes into production.
Under a blue-green model, the production environment is cloned. Live traffic runs through one environment while changes are introduced to the other, and then traffic is cut back across.
