Cluster
A cluster handles final routing of each request to its intended target. Each cluster can have 0 or more instances defined, which are simply the host:port pairs of the targets. Instances within a cluster can be statically configured when the object is created, or dynamically loaded through the service discovery mechanisms.
Features
- Static or dynamic instances
- Circuit breakers
- Health Checks
- Outlier Detection
- Outgoing SSL configuration
- Directly via SSL certs on disk
- Through SPIFFE/SPIRE and Envoy SDS
