It's easy to install and wield during daily use, and while you can get very granular, quick configuration changes are possible.

Like service discovery, routing, load balancing, and so on.

Accelerates delivery by managing microservices, but can present security challenges. Service mesh enables the decoupling of service communications from the application logic of that service via a sidecar proxy -- an extended version of the Envoy proxy -- that picks up responsibility for managing traffic and communication between services. At the core, Envoy is a network proxy operating at the L3 and L4 layers of the OSI model.
