-description: "We loved the simplified syntax, strong standard library, great external community, and well-built and maintained libraries. We loved the fast compile times and incredibly small images we could build when deploying containers. As we continue to grow and scale our technical solutions to our guests, we find the concurrency primitives in Go particularly useful."
