During the linkerd … Linkerd, Consul Connect, and Istio are top service meshes, but Kuma, Traefik Mesh, and AWS App Mesh are considerable contenders as well. One of the challenges for the Linkerd project is that Google, the creator of Kubernetes, sponsors an alternative service mesh called Istio, although the company's governance decisions have caused some disquiet in the open-source community. It relies on the load balancer to route secondary protocols to the same UAG appliance as was selected for the primary Horizon protocol.

Configure Ambassador Edge Stack to add it to the Linkerd 2 service mesh. Session affinity or persistence settings on the Ingress Citrix ADC allows you to direct client requests to the same selected server regardless of which virtual server in the group receives the client request. When the configured time for persistence expires, any virtual server in the group is selected for the incoming client requests. Certainly, you have heard the term service mesh in the context of Kubernetes. . The hostname of the backend. The Problem. Linkerd injects a side car proxy to add the deployment to it’s data plane. In this blog post, we will take a look at installing Linkerd, verify if traffic between YugabyteDB pods is secured with mTLS. The load balancer will distribute the first transaction to one server (based on a chosen algorithm). Session affinity Session affinity overrides the load-balancing algorithm by directing all requests in a session to a specific application server.
