At a managed control plane service, constituent services and operational requirements of an application are identified. In response to an end-user request directed to the application, contents of an inter-service request are generated at a resource selected by the managed control plane service for a first constituent service, and a response to the message is generated at another resource selected for a second constituent service. Tasks to be performed for the operational requirements are initiated by the managed control plane service.

Managed integration of constituent services of multi-service applications

A virtual computer system service receives a request from a customer to provision a dedicated server for the exclusive use of the customer. The dedicated server may be used to launch one or more virtual machine instances. The virtual computer system service subsequently selects, from a pool of available servers, a server that can be dedicated to the customer and that does not have capacity allocated to any other customer. The virtual computer system service may update a database to specify, in an entry corresponding to the selected server, that the server has been dedicated for the exclusive use of the customer. Once the database has been updated, the virtual computer system service will enable the customer to launch a virtual machine instance using the dedicated server.

Dedicated virtual computing system servers

Techniques are described for enabling users of a cloud provider network to define and use custom 'virtual regions' comprised of selected sets of cloud provider network infrastructure locations. A cloud provider network enables users to obtain information about available infrastructure locations and to identify locations that satisfy a set of performance characteristics and other parameters. Once a set of desirable infrastructure locations have been identified, users can request the creation of a virtual region to be associated with their user account, where the request specifies a set of infrastructure locations to comprise the virtual region. Once a virtual region is created, users can cause computing resources to be launched into or otherwise associated with the virtual region in a manner similar to the use of existing regions and availability zones.

User-defined virtual regions in a cloud provider network

A component of a computing service obtains respective indications of placement policies that contain host selection rules for application execution environments such as guest virtual machines. With respect to a request for a particular application execution environment, a group of applicable placement policies is identified. A candidate pool of hosts is selected using the group of placement policies, and members of the pool are ranked to identify a particular host on which the requested application execution environment is instantiated.

Custom placement policies for virtual machines

A control-plane component of a network-accessible service receives an indication that a resource request has been submitted by a client. The component determines, based at least in part on metadata associated with the client, that a first parameter selection policy (PSP) of one or more PSPs created for the service is applicable. The first PSP includes a condition set to determine applicability, and a value set indicating parameter values to be used to fulfill resource requests to which the PSP applies. Using the value set, an effective parameter value list for one or more operations to be performed to allocate the requested resource is generated, and the allocation operations are initiated.

Policy-based allocation of provider network resources

A service workflow agent associated with a particular service of a provider network identifies a repository in which workflow descriptors indicative of tasks to be performed by the service are stored. In response to determining that a modification has been applied at one such repository, the agent examines a particular workflow descriptor stored in the repository. The agent initiates an attempt to implement a first task indicated in the descriptor. Subsequently, the agent updates the descriptor in accordance with an optimistic concurrency control technique to indicate a status of the first task.

Decentralized management of multi-service workflows

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.

Hardware grouping based computing resource allocation

Techniques for optimistic locking of virtual machine instances during a migration are described herein. Application programming interface requests are classified by type. When a request such as an application programming interface request is received during the migration of a virtual machine instance from a source location to a target location, the request is classified according to the type and according to the state of the migration. Based on that classification, it is determined whether to block the request, allow the request, or cancel the migration.

Optimistic locking in virtual machine instance migration

A technology is described for determining a placement of a computing instance within a virtualized computing service. An example method may include receiving a computing group state for a server that provides a virtualized computing service. The server may include a computing slot which may be used to execute a computing instance. Weighting values for placement factors may be identified for the computing group state. A placement score may be calculated for the computing slot based at least in part on the weighting value for the placement factor.
