At a recovery manager associated with a cluster, a determination is made as to whether a replacement for a first node of the cluster can be elected by the other nodes of the cluster using a first election protocol. The recovery manager selects a second node of the cluster as a replacement for the first node, based on data item replication progress made at the node, and transmits an indication that the second node has been selected to one or more nodes of the cluster.

Hybrid cluster recovery techniques

A network metering service obtains from a data store raw metering data specifying network bandwidth utilization for a plurality of customers. The network metering service aggregates this data in order to identify bandwidth usage for each service of a computing resource service provider and for each customer. Based on this data, the network metering service determines a peak-to-average score and a correlation coefficient for each customer, which may be used to determine a unit cost burden. The network metering service may utilize the unit cost burden for each customer to determine whether the customer should be provided with a discounted rate for network bandwidth usage or should incur a price increase.

Bandwidth cost assignment for multi-tenant networks

Approaches are described for enabling a host computing device to store credentials and other security information useful for recovering the state of the host computing device in a secure store, such as a trusted platform module (TPM) on the host computing device. When recovering the host computing device in the event of a failure (e.g., power outage, network failure, etc.), the host computing device can obtain the necessary credentials from the secure store and use those credentials to boot various services, restore the state of the host and perform various other functions. In addition, the secure store (e.g., TPM) may provide boot firmware measurement and remote attestation of the host computing devices to other devices on a network, such as when the recovering host needs to communicate with the other devices on the network.

Remote attestation of host devices

A dynamic configuration system can manage and configure switches or other network devices that come online in a network. When the dynamic configuration system determines that a network device has come online, the dynamic configuration system can identify the network device (e.g., based on its network location, neighbors, fingerprint, identifier, address or the like), select the appropriate configuration data for the network based on the desired network topology, and transmit the configuration data to the network device. The network device can then load the configuration data and function as a component of the desired network topology.

Dynamic network device configuration

The following description is directed to configuring network devices. In one example, at a network device deployment pipeline, a request can be received from a non-integrated configuration tool to configure a network device of a network. The configuration of the network device can be scheduled so that both an integrated configuration tool of the network device deployment pipeline and the non-integrated configuration tool can configure the network.

Network device configuration deployment pipeline

The following description is directed to topologically aware network device configuration. In one example, components to be configured within a network can be mapped to one or more redundancy groups within a network topology of the network. The components to be configured can be selectively configured within the network so that network traffic continues during the configuration. Selectively configuring the components can include choosing an order to configure the components based on configuration rules and the mapping of the components to the one or more redundancy groups.

Topologically aware network device configuration

Approaches are described for managing configuration information updates, or other information in a data center, shared resource environment, or other such electronic environment. A management component is provided that can manage distribution of configuration information, operating system (OS) images, authentication data, or other such information for host machines, servers, or other such devices in a network environment. The management component can further perform a number of actions when deploying configuration information updates, such as performing one or more checks to verify the health of a target switch, deactivating the target switch, shifting traffic to and from the target switch, updating a current configuration of the target switch, verifying the target switch's health after the configuration changes, bringing the target switch back in service, among others.

Managing configuration updates

Host recovery using a secure store

The following description is directed to configuring network devices. In one example, a deployed configuration for a network device can be collected. The deployed configuration can be representative of a state of the network device at the time of collection. A difference can be detected between the deployed configuration and an authoritative configuration for the network device. In response to detecting the difference, an update of the network device according to the authoritative configuration for the network device can be scheduled.
