Abstract: A system, method, and computer readable medium is disclosed for accessing an object that is encrypted within at least a tertiary-level encryption key scheme. This includes receiving a request to access blocks making up an object by content management system and using a top-level encryption key from a key management service, a namespace encryption key from a namespace encryption key database, and a respective block encryption keys protecting the blocks making up the object. Using these keys, the system can decrypt the block encryption keys using the namespace encryption key and decrypt the blocks using the block encryption keys, thereby providing access to the object.

Abstract: A service management system manages scaling and migration of a plurality of services in a content management system. The service management system may maintain a plurality of services that are distributed across a plurality of clusters, each service serving a functionality in the content management system. Responsive to receiving a request to scale a service, the service management system may access dependency data describing dependencies among the plurality of services. Based on the dependency data, the service management system may determine a set of services to scale and determine a scaling sequence in which the set of services are to be scaled. The service management system may further determine other parameters for the scaling process such as scaling ratios, allocation ratios and scaling factors associated with the services and the scaling is further based on the parameters.
