Scaling Fly for All

Dj Walker-Morgan introduces the scaling controls feature on Fly, which allows users to control the number of instances of their applications running in different regions around the world. The update also includes changes to the scaling system and commands for simplicity. Users can now use flyctl scale regions command to view or set the regions where their app is running and minimum instance counts. Additionally, they can scale the size of their application's virtual machines using the flyctl scale vm <sizename> command. The Fly platform offers various VM sizes with different memory and vCPU core configurations, and users can choose the one that suits them best.
