Abstract: A network-based data store maintaining storage volumes for file systems at storage clients may implement dynamic storage volume scaling. A scaling event may be detected according to a specified scaling policy for a storage volume maintained at a network-based data store that is mounted at a storage client and configured for a file system. In a least some embodiments, the scaling policy for the storage volume may be received from the storage client. In response to detecting the storage event, storage maintaining the storage volume may be modified according to the scaling policy to scale the storage volume. An indication of the scaling event may be sent to the storage client in order to update the file system at the storage client so that the file system may utilize the scaled storage volume.

Abstract: Methods and apparatus for client-directed placement of remotely configured service instances are described. One or more placement target options are selected for a client of a network-accessible service based on criteria such as service characteristics of the placement targets. The selected options, including a particular placement target that includes instance hosts configurable from remote control servers, are indicated programmatically to the client. A determination is made that a service instance is to be configured at the particular placement target on behalf of the client. A remote control server is configured to issue administrative commands to an instance host at the particular placement target to configure the service instance.

Abstract: Techniques described and suggested herein include systems and methods for updating, adding, deleting, managing, and otherwise manipulating instance data across multiple virtual instances in an addressable fashion. For example, a customer may control or otherwise be associated with a fleet of virtual instances running on one or more hosts of a computing resource service provider. The described techniques enable customers, or other entities, to update instance data related to arbitrarily defined groups of the fleet using, e.g., tags or other common identifiers, so as to, e.g., alter operational characteristics of some or all of a given fleet of virtual instances without necessitating individual alteration of each instance.

Abstract: Method and apparatus for activating a computing instance are disclosed. In the method and apparatus, a computing instance is activated if received traffic addressed to the computing instance is determined to satisfy one or more conditions for computing instance activation. Following activation, the data may be sent to the computing instance for processing.

Abstract: Systems and methods for providing on-demand diagnostics in a virtual environment are disclosed. In one embodiment, a method comprises storing a list of approved diagnostic tests. A diagnostic service can be running in the multi-tenant environment. The diagnostic service can receive a request to run a selected diagnostic test from the list of approved diagnostic tests on one or more hardware resources in the virtual environment. In response to the request, the selected diagnostic test can be transmitted to the one or more hardware resources.

Abstract: A customer submits a set of preferences including hardware specifications for instantiating a virtual machine instance. The virtual machine instance may be instantiated in a physical host computer system that does not conform to the set of preferences. The virtual computer system service may be configured to evaluate the specifications of the available physical host computer systems to determine whether any of the available physical host computer systems conform to the set of preferences. Accordingly, the virtual computer system service may further evaluate the available physical host computer systems to determine whether available physical host computer systems comprise available slots for instantiating the existing virtual machine instance. If the one or more available physical host computer systems have available slots, the virtual computer system service may migrate the existing virtual machine instance to an available physical host computer system in order to fulfill the customer request.

Abstract: Attacks, such as MITM and DoS attacks, on a distributed computing system may be detected by sending a work assignment to an execution device through a first communication channel. A report may then be received through a second communication channel of the work assignment received by the execution device. Information regarding the received work assignment may then be in view of information regarding the sent work assignment to determine whether an error, such as an MITM or DoS attack, has occurred. If the analysis indicates that the report does not include the sent work assignment, then a DoS attack may have occurred. If the analysis indicates that the work assignment received by the recipient does not correspond to the sent work assignment, then a MITM attack may have occurred. If an error has occurred, an indication might be recorded and/or other types of actions might also be taken.

Abstract: An example method of launching a virtual machine in a multi-tenant environment using dynamic configuration may include receiving a customer request to launch a virtual machine in the multi-tenant environment. The multi-tenant environment may include a plurality of host server computers. In response to the customer request, configuration parameters stored in association with an account of the customer may be retrieved in the multi-tenant environment. One or more parameters of a hardware and/or a software resource in the multi-tenant environment may be dynamically configured in accordance with the retrieved configuration parameters. The virtual machine may be launched on one of the plurality of host server computers, using the configured hardware and/or software resource. The configuration parameters may be associated with at least one desired performance characteristic of the virtual machine to be launched.
