Workshop - Service Mesh Hub

Managing a service mesh deployment that is consistent and secure across multiple clusters is tedious, error prone at best, and raises questions like:

* How should I deploy and manage multiple clusters of service mesh?
* What if my service meshes span across on-prem and cloud?
* What traffic control or security policies do I need to consider across multiple clusters?

Service Mesh Hub is a Kubernetes-native control plane to unify and simplify the operation of multi-cluster service mesh including concerns like service discovery, identity and trust domains, access control, cross cluster traffic, failover and more.

In this hands-on workshop we will explore different service mesh deployment patterns, multi-cluster topologies, and how Service Mesh Hub can address the configuration and operations needs for these environments.

Covered in this workshop:
* Deploy Istio onto two clusters
* Discover and unify the clusters to form a virtual mesh
* Configure cross cluster microservices communication
* Create access control policies
* Simulate traffic failover scenarios

23. 23 | Copyright © 2020 Service to Service Authentication • By default the TLS protocol only proves the identity of the server to the client using X.509 certificate and the authentication of the client to the server is left to the application layer. • Mutual TLS authentication refers to two parties authenticating each other at the same time. • In Istio, Mutual TLS work as follow: − Istio re-routes the outbound traffic from a client to the client’s local sidecar Envoy. − The client side Envoy starts a mutual TLS handshake with the server side Envoy. During the handshake, the client side Envoy also does a secure naming check to verify that the service account presented in the server certificate is authorized to run the target service. − The client side Envoy and the server side Envoy establish a mutual TLS connection, and Istio forwards the traffic from the client side Envoy to the server side Envoy. − After authorization, the server side Envoy forwards the traffic to the server service through local TCP connections.
24. 24 | Copyright © 2020 SPIFFE ID • SPIFFE, the Secure Production Identity Framework for Everyone, is a set of open- source standards for securely identifying software systems in dynamic and heterogeneous environments. Systems that adopt SPIFFE can easily and reliably mutually authenticate wherever they are running. • A SPIFFE ID is a string that uniquely and specifically identifies a workload. SPIFFE IDs are a Uniform Resource Identifier (URI) which takes the following format: spiffe://trust domain/workload identifier
25. 25 | Copyright © 2020 SPIFFE ID in Istio • The SPIFFE ID of a workload looks like spiffe://<trust domain>/ns/<namespace>/sa/<service account> • The default trust domain is cluster.local, so a the SPIFFE ID corresponding to a Pod started with the service account pod-sa in the default namespace would be spiffe://cluster.local/ns/default/sa/pod-sa. • In a multi-cluster deployment, using the cluster.local trust domain is a problem because there would be no way to differentiate a workload of a cluster from one of another cluster if they use the same service account and namespace names. • Istio allows you to use a different trust domain using the trustDomain parameter of the MeshConfig option.
