Android emulators are at the backbone of mobile app testing—but once your team grows, local emulators won’t keep up. In this talk, we’ll explore the real-world trade-offs between cloud providers, self-hosted VMs, and baremetal machines for running emulators on cloud. Drawing from Maestro’s journey of scaling to 5,000–10,000 UI tests daily across Android and iOS, we’ll discuss insights on different criteria of selection. Expect having a clear framework for choosing the right emulator infrastructure—whether you’re a startup running nightly tests or an enterprise supporting thousands of runs per day.
