Patent attributes
Techniques are described for allocating computing resources to customers of a multi-tenant web services platform. Computing capacity capable of running a computing instance is allocated to a customer. The computing capacity includes storage capacity that is disassociated from the allocated computing capacity when the allocated computing capacity is de-allocated from the customer. An indication that a virtual storage resource should be associated with the allocated computing capacity is received. The virtual storage resource is persisted independent of the allocation of the computing capacity to the customer. The storage capacity and the virtual storage resource are configured to synchronize data stored thereon while maintaining the storage capacity as an attached storage volume for the computing instance.
