AWS App Mesh has increased the default limits for a set of App Mesh resources - virtual nodes, backends, routers, and routes. These limit increases make it easier for you to manage larger applications with App Mesh. The number of virtual nodes per mesh, which map to your services, tasksets, or deployments that can be connected to the mesh, increased from 20 to 200. The number of backends per node; the number of dependent services that a specific service can connect with, increased from 25 to 50. The number of virtual routers per mesh increased from 20 to 200, to enable routing on all mesh connected services. The number of routes per virtual router increased from 20 to 50, to enable matching on multiple parameters for routing decisions.  

The new limits apply in all regions where App Mesh is available. The higher limits are reflected in your accounts automatically, and there is no further action required on your end. If you have approved limits that are higher than the new limits, then you continue to have the higher limits. To learn more about AWS App Mesh limits, visit our documentation.
