Want to observe a service mesh that extends to virtual machines? A new analyzer in Apache SkyWalking the application monitoring (APM) system designed especially for microservices, cloud native and container-based architectures leverages Envoy’s metadata exchange mechanism to work in Kubernetes, VM or hybrid environments.
In a previous article, we talked about observability of service mesh in a Kubernetes environment and applied it to the bookinfo application in practice. But in that scenario, in order to map IP addresses to services, SkyWalking would need access to service metadata from a Kubernetes cluster which is not available for services deployed in VMs. In this tutorial, we’ll demonstrate how SkyWalking’s new analyzer can give you better observability of a mesh that includes virtual machines.

Istio has a big service mesh lead, but only among a segment of early adopters. Among those already using a service mesh in production, 63% have adopted Istio, which is more than twice as many as Linkerd according to our analysis of the Cloud Native Computing Foundation’s (CNCF) survey earlier this year. Besides HashiCorp’s Consul, no other option broke double digits.
Istio isn’t as intimidating if you strip away the fact that it is commonly deployed along with Envoy, which has undeniably done well recently. Production use of the Envoy project among the CNCF community rose from 17% in 2019 to 24% in 2020. Those evaluating the project dropped from 35% to 21%, which may mean that many organizations considered and rejected Envoy, which can have implications for future service mesh adoption. Not everyone associates Envoy with service proxy or ingress control. When the survey screened for the adoption of this functionality, only 18% used Envoy in a production or evaluation situation
