Given the popularity of Docker, Google launched Kubernetes management docker cluster, and many people are expected to try. Kubernetes is supported by a large number of companies, and the Kubernetes Cluster deployment Tool integrates the IaaS platform such as Gce,coreos,aws, which is also very convenient to deploy. Given that many of the online materials are based on a number of older versions, this article provides a brief description of the latest ku

The GRPC-LB uses client-side in-process load balancing, supports random, polling, consistent hash three load balancing policies, and supports server-side weighting. You can use ETCD or consul as a registry.

When an external request occurs, the Proxy will distribute the request to the correct backend container for Processing Based on Load Balancer. Therefore, the Proxy not only solves the conflict between the same Service
