What is a service mesh?
For all the hype, the service mesh is architecturally pretty straightforward. It’s nothing more than a bunch of userspace proxies, stuck “next” to your services (we’ll talk about what “next” means in a bit), plus a set of management processes. The proxies are referred to as the service mesh’s data plane, and the management processes as its control plane. The data plane intercepts calls between services and “does stuff” with these calls; the control plane coordinates the behavior of the proxies, and provides an API for you, the operator, to manipulate and measure the mesh as a whole.

What about Istio?
Istio makes it easy to create a network of deployed services with load balancing, service-to-service authentication, monitoring, and more, with few or no code changes in service code. You add Istio support to services by deploying a special sidecar proxy throughout your environment that intercepts all network communication between microservices, then configure and manage Istio using its control plane functionality…

Istio’s traffic routing rules let you easily control the flow of traffic and API calls between services. Istio simplifies configuration of service-level properties like circuit breakers, timeouts, and retries, and makes it easy to set up important tasks like A/B testing, canary rollouts, and staged rollouts with percentage-based traffic splits. It also provides out-of-box failure recovery features that help make your application more robust against failures of dependent services or the network.

Just as tech is revised and upgraded, so too should a tool comparison be. Service meshes act as the substrate to connect microservices, find the one for you.
For teams to monitor, support, and to maintain these services is becoming a challenge so most enterprises have invested in some kind of microservices management tool.
