A migration management service can partition a service and migrate resource data without requiring the resource to be taken offline. The migration management service can receive a request to partition a service into multiple partitioned services that are independent of one another. The request can identify one or more resources associated with each partition. For example, a single service receiving data for resources throughout the world can be divided into multiple regional services, where each regional service is independent of the others. The migration management service can track the status of data while migrating. As new messages are received from resources, the migration management service can determine the migration status of the resources. If the data for a resource is not migrated, the original data store can be used. However, if the data is migrated, the message can be forwarded to the appropriate partition for further processing.

Migrating data between partitioned databases

Technologies are provided for running multiple firmware instances in a board management controller (BMC). The BMC can comprise a virtualization controller configured to manage multiple virtualized firmware instances in separate virtual machines or virtualization containers. One of the firmware instances can be an instance of an older BMC firmware, and another of the firmware instances can be an instance of a newer BMC firmware configured to delegate control of hardware components it does not support to the instance of the older firmware. As the newer firmware is updated to support additional hardware components, the instance of the older firmware's control of those components can be disabled. BMC commands can be received and routed to the multiple firmware instances that support them for processing.

Board management controller firmware virtualization

Technologies are provided for running multiple firmware instances in a board management controller (BMC). A BMC can be configured to execute a first BMC firmware natively and to execute a virtualized second BMC firmware in an emulator. The virtualized second BMC firmware can be an instance of an older BMC firmware, and the first BMC firmware can be an instance of a newer BMC firmware configured to use the emulator to delegate control of hardware components it does not support to the instance of the older firmware. As the newer firmware is updated to support additional hardware components, the instance of the older firmware's control of those components can be disabled. BMC commands can be received and routed to the multiple firmware instances that support them for processing.

Techniques for interruption-free partitioning

A custom host errors definition service is provided. The custom host errors definition service can create separate endpoints through which different customers can define custom host errors for one or more host computing systems, which might operate in a distributed execution environment. A custom host error definition can specify one or more host computing systems, one or more system components of the one or more host computing systems, one or more attributes, one or more error conditions for the one or more attributes, and one or more actions to perform as a result of the error conditions being satisfied. The error conditions can be, but are not limited to, threshold conditions, component failure conditions, missing hardware conditions, degraded hardware conditions, system firmware failures, incorrect firmware conditions, and the like.

Each server in a server group of a data center can run a data collection agent. The agent can collect data from a respective server in the server group. The data can include a performance characteristic (i.e., performance data) associated with the respective server. If the performance characteristic falls outside an allowable range, the agent can broadcast this information to other agents at other servers in the server group. If the other agents at the other servers in the server group detect a similar performance characteristic outside the allowable range, they can broadcast as well. If there is a sufficiently high quantity of broadcasts, then that can indicate a high likelihood that there is a potential problem with respect to servers in the server group. The problem can be reported to the central controller, which can then handle the problem appropriately (e.g., issue an alarm, contact support technician, etc.).
