The team installed a service mesh to manage their cloud applications.
By implementing a service mesh, the developers were able to monitor traffic between microservices without changing any of the underlying application logic.
As the architecture scaled to hundreds of individual containers, the service mesh became essential for maintaining mutual TLS encryption and providing granular observability across the entire distributed system.
A compound of service and mesh. The term emerged from the infrastructure engineering sector to describe the interconnected network of microservices, following the established architectural metaphor of a network topology as a woven fabric.
