Automated scheduling of virtual machines across hosting servers
View Patent ↗Some embodiments provide a method and system for automatedly scheduling virtual machines across several hosting servers of a hosting service provider. Some embodiments perform the automated scheduling by receiving a server configuration that includes constraint data. In some embodiments, the constraint data includes a specified amount of hosting resources needed to implement the server configuration. Based on the constraint data, a scheduling module in the hosting environment determines an optimal distribution of the server configuration across a set of hosting resources that implement the server configuration based on the constraint data. To determine the optimal distribution, some embodiments compute a set of scores for quantifying the specified set of hosting resources required for hosting the server configuration. From the optimal distribution, some embodiments perform a mapping of the server configuration to a particular set of hosting resources of several hosting resources using the computed set of scores.
