Scaling a virtual machine instance

Abstract

Techniques are described for scaling of computing resources. A scaling service is utilized that allocates additional computing resources (e.g., processors, memory, etc.) to a virtual machine instance (or other compute instance) and/or de-allocates computing resources from a virtual machine instance according requests and/or thresholds. In addition to the foregoing, other aspects are described in the description, figures, and claims.
