Applications can switch from being robust to resilient through the use of Linkerd's sidecar proxy, which provides adaptive load balancing, easy to understand debugging capabilities, timeouts, and retries. We explored each of these capabilities in this chapter.
With the help of a service profile through Kubernetes' custom resource definition, you can define routes to report aggregated metrics on unique requests based on defined patterns. The service profile name is a fully qualified name that can match with HTTP/2 :authority or HTTP1.X hosts.

You can implement retry budgets to prevent retry storms from overwhelming backends.
The Linkerd dashboard or the Linkerd CLI can be used to observe the live traffic arriving in...
