# gvisor vs microservices-demo

gvisor and microservices-demo share 4 technologies: Redis, Google, cloud.google.com/go/compute/metadata, and github.com/sirupsen/logrus. Both are written in Go.

- [google/gvisor](https://seerepo.com/r/google/gvisor): Application Kernel for Containers
- [GoogleCloudPlatform/microservices-demo](https://seerepo.com/r/GoogleCloudPlatform/microservices-demo): Sample cloud-first application with 10 microservices showcasing Kubernetes, Istio, and gRPC.
