For more information about\nVPC Service Controls, see [Overview of VPC Service Controls](/vpc-service-controls/docs/overview).\n\nOnce the Memorystore for Memcached API is protected by your service perimeter,\nMemorystore for Memcached API requests coming from clients outside of the perimeter\nmust have the proper access level rules.\n\nProtecting your Memcached instances using VPC Service Controls\n--------------------------------------------------------------\n\n1. [Create a service perimeter](/vpc-service-controls/docs/create-service-perimeters).\n\n2. Add the Memorystore for Memcached API to your service perimeter. For\n instructions on adding a service to your service perimeter, see\n [Updating a service perimeter](/vpc-service-controls/docs/manage-service-perimeters#update).\n\nConfiguration requirements\n--------------------------\n\nIf you use both Shared VPC and VPC Service Controls, you must have the host\nproject that provides the network and the service project that contains the\nMemcached instance inside the same perimeter in order for Memcached requests to\nsucceed. Otherwise, requests between the service project instance and the host\nproject network are be blocked by the VPC Service Controls service perimeter.\n\nAt any time, separating the host project and service project with a perimeter\ncan cause a Memcached instance failure, in addition to blocked requests.\n\nLimitations of VPC Service Controls for Memcached instances\n-----------------------------------------------------------\n\nFor a list of VPC Service Controls limitations for\nMemorystore, see [Supported products and limitations](/vpc-service-controls/docs/supported-products#table_memstore-memcache)\n\nWhat's next\n-----------\n\n- Learn more about Auto Discovery with the [Auto Discovery service overview](/memorystore/docs/memcached/auto-discovery-overview).\n- View the available [Memcached configurations](/memorystore/docs/memcached/memcached-configs)."]]
