Multi Cluster and Multi Mesh Patterns

Explore multi-cluster and multi-mesh patterns in this 32-minute conference talk by Christian Posta from Solo.io. Dive into the challenges and solutions for adopting service meshes across multiple clusters and meshes, including federating identity, unified observability, and policy development. Learn about different patterns such as flat network across pods, controlled gateways, and separate networks. Discover how Envoy serves as the backbone for multi-cluster communication federation, offering features like request hedging, retry budgets, and zone-aware routing. Examine various configurations including shared control planes with flat or separate networks, and separate control planes with separate networks. Gain insights applicable to Istio, Linkerd, and App Mesh implementations.

Intro
CHRISTIAN POSTA
Cluster federation
Pattern: flat network across pods
Pattern: Different network, expose all services
Pattern: Different network, controlled gateway
Forces to balance
Envoy is the magic behind service mesh
Envoy to do application networking heavy lifting
Envoy as backbone for multi-cluster communication federation
Other key Envoy proxying features .. Request hedging Retry Budgets
Zone aware routing (Envoy decides)
Locality aware (Control plane decides)
Aggregate Cluster (for routing to gateways)
Shared control plane, flat network
Shared control plane, separate networks
Separate control planes, separate networks
