Abstract: A workload of a database may be evaluated to provide a database migration recommendation. A request for a recommendation to migrate a database to a new host may be received. An evaluation of the workload of a client application of the database at a current host may be performed. The migration recommendation may be returned based on the evaluation of the workload of the client application of the database. In some embodiments, the migration recommendation may trigger an automated migration of the database to the new host.

Abstract: Method and apparatus for preventing communications with potentially compromised computing instances are described. An example method generally includes receiving, from a requesting device, a request to interact with the resource instance in the computing environment. A system examines current ownership information associated with the resource instance in the computing environment and determines that the resource instance is potentially compromised based, at least in part, on a determination that the ownership information associated with the resource instance has changed from the owner identified in a historical record to a second owner. Responsive to the determination that the resource instance is potentially compromised, the system takes action to manage communications with the resource instance so as to prevent the requesting device from sharing information with the resource instance.

Abstract: Distributed extraction of data for migration may be implemented for migrating data sets from a first data store to a second data store. Assignments may be determined for different migration agents to obtain and store the data set in the second data store along with a format for storing the assigned data set portions. The migration agents may then be caused to obtain the assigned portions and store the assigned portions in the second data store according to the identified format. Further operations to request or direct the ingestion of the data set from the second data store may be performed by migration agents with respect to a third data store that performs data ingestion.
