Abstract: A distributed system may implement network locality-based throttling for automatic resource migration. Utilization of a distributed system that includes multiple resources at multiple resource hosts may be monitored. New migration operations to migrate a resource in the distributed system may be evaluated with respect a migration operation limit for one or more network localities of the distributed system. If the migration operation limit for the one or more network localities is exceeded, then the new migration operations may be throttled. Different network localities may have different migration operation limits.

Abstract: A distributed system may implement opportunistic resource migration to optimize resource placement. Resources may be placed amongst different resource hosts of a distributed system. An evaluation of the current placement may be performed according placement criteria that improve placement of the resources at the distributed system. Based on the evaluation, the prospective migration of resources that exceed an improvement threshold may be identified as candidate resources to migrate. Migration for the candidate resources may be opportunistically performed. In some embodiments, a priority may be assigned to the candidate resources according to which the candidate resources are selected for performing migration.

Abstract: Described embodiments provide systems and methods for remapping connections to tunnels selected based on a security level of the communications. A first network device may be in communication with a second network device via a plurality of communication tunnels. The plurality of communication tunnels may include an encrypted communication tunnel and an unencrypted communication tunnel.

The first network device may determine whether the received packet is encrypted to meet a threshold level of security. The first network device may, responsive to determining that the packet is to meet the threshold level of security, communicate an identifier of the payload and the header information to the second network device via the encrypted communication tunnel, and communicate the payload to the second network device via the unencrypted communication tunnel.

Abstract: A customer of a computing resource service provider submits a request to a virtual computer system service to instantiate a virtual computer system. In response to the request, the service obtains physical network information in order to identify any hardware groupings that may be used, at a later time, to provision one or more data storage volumes that may be associated with the virtual computer system. The service assigns a score to each of these hardware groupings based at least in part on the available capacity for provisioning of these data storage volumes. Based at least in part on these assigned scores, the virtual computer system service selects a hardware grouping and instantiates the virtual computer system within the selected hardware grouping.

Abstract: A distributed system may implement prioritizing resource hosts for resource placement. A placement request for a resource to be placed in a distributed system at a resource host may be received. Available resource hosts may be filtered out according to placement constraints. The resource hosts may be assigned to different priority sets according to a priority scheme for placing resources at resource hosts. Evaluations of resource hosts from the different priority sets may be performed to select candidate resource hosts to provide as possible placement locations.

Abstract: A distributed system may implement analyzing bit vectors for resource placement. Bit vectors may be maintained or generated for currently hosted resources in a distributed system according to placement criteria so that individual bit values of a bit vector indicate whether a corresponding one of the placement criteria is satisfied for the current placement of the resource. A resource may be identified for migration and a possible placement determined for the resource. A bit vector may be generated for the possible placement and compared with the bit vector for the current placement of the resource to determine whether the possible placement improves the placement of the resource with respect to the placement criteria.

Abstract: The allocation of resources, such as for data storage, can be performed based at least in part upon predicted values for utilization and growth, among other such values. Various features can be used to predict the initial utilization and growth rate for a data volume, and these predicted values can be used to determine where to place the volumes. The features can include, for example, customer usage history, volume type, volume purpose, type of attached virtual machine, and the like. The ability to predict actual usage can enable capacity to be allocated based on an as-needed basis instead of providing large blocks of allocated capacity that would go largely unused. Similar predictions can be used to determine whether and where to migrate data volumes so as to maintain sufficient capacity across a group of resources.

Abstract: A distributed system may implement optimizing for infrastructure diversity in resource placement. A placement request for a resource to be placed at one of multiple resource hosts respectively implemented at infrastructure units may be received. An evaluation of utilization data for the multiple resource hosts may be performed with regard to an infrastructure diversity constraint for placing resources at the infrastructure units. A selection of a resource host may be made based on the evaluation of the utilization data according to the infrastructure diversity constraint. In some embodiments to select the resource host, the effect of placing the resource on candidate resource hosts on an infrastructure-diverse capacity metric may be determined to score the candidate resource hosts. The resource may be placed at the selected resource host.
