 *sidekick* is a high-performance sidecar load-balancer. By attaching a tiny load balancer as a sidecar to each of the client application processes, you can eliminate the centralized loadbalancer bottleneck and DNS failover management. *sidekick* automatically avoids sending traffic to the failed servers by checking their health via the readiness API and HTTP error returns.
