You’re ready to send some canary traffic to a newly refactored application in a new cloud provider while the former application resides in your current datacenter or cloud. However, you encounter a problem: you haven’t aggregated application metrics from both environments, and you’ll have to manually review a dashboard to determine whether or not to increase the percentage of canary traffic. Is there an automated way to do this? In this talk, Rosemary combines canary analysis with the powers of service mesh observability and traffic management to supercharge migrations in multiple environments with progressive delivery. She’ll demonstrate that setting up tools such as HashiCorp Consul, Prometheus, and Spinnaker can help scale the migration and support of refactored applications across multiple clouds or platforms while reducing their production risk.
