# Service mesh configuration

Google Cloud’s fully managed service mesh lets you manage complex microservices architectures so that you can get all the benefits of microservices without the overheads. It allows you to configure, control, secure and monitor your services in one place, taking a significant burden off your operations and development teams. More information on Anthos Service Mesh is available at https://cloud.google.com/anthos/service-mesh.
