SkyWay, the largest WebRTC platform in Japan, is deployed all over the world with AWS. This is realized by HashiCorp tools like Terraform, Vagrant, Consul, and Serf. To develop infrastructure effectively, we have not only built infrastructure with HashiCorp tools, but also tested with other tools such as Serverspec and drone.io. As a result, similar to application development which often includes "development and test" loop, our infrastructure is developed and managed by the loop.
