Duolingo's Kubernetes Leap. Non l'ho visto, ma qui Duolingo spiega la migrazione da AWS ECS a EKS.
To give you an idea of the scale that we're looking at, Duolingo currently has over 128 million monthly active users, and we have over 250 courses that you can learn on the app. [...] On the engineering side, we have over 400 engineers and more than 500 backend services, just to give you an idea of the scale of this migration that we're going to be looking at today.
Previously, the 500-plus backend services that I mentioned at the beginning are running on AWS ECS. We have some workloads that are running on different infrastructure, but for the mass majority, they're on ECS. That's what I'm going to be focusing on. We're going to be moving from ECS to EKS. ECS is AWS's container orchestration solution. It's a managed solution. It's very simple and straightforward to use. We've been actually super happy with ECS over the past year, and it served our needs very well. Now as we've grown to a much bigger scale, as I mentioned, Kubernetes just offers a much more feature-rich ecosystem and open-source platform, as well as specific features that ECS does not give us.
