    Abstract: Techniques are described for providing a multi-service storage layer in a cloud provider network for applications and workloads that are highly sensitive to outages affecting “mission critical” data or other resources. A multi-service storage layer is designed to provide additional resiliency against various types of correlated failures among existing geographic regions by enabling the storage of data using a plurality of separate storage services and storage resource types and across a plurality of regions of the cloud-provider network. A multi-service storage layer provides an application programming interface (API) with actions for storing, retrieving, and querying data stored in a highly available storage resource across a selection of underlying storage services. The ability to store critical data and other resources using a multi-service storage layer provides additional resiliency while also providing a single interface that applications can use to interact with the data stored across any number of underlying storage services.

    Abstract: Techniques are described for enabling users to create reservations for compute capacity at a service provider network intended for use in disaster recovery scenarios. A service provider can use separate geographic areas (sometimes referred to as “regions” or “availability zones”) defined by the service provider network to enable users to share reservations of compute capacity intended for use in disaster recovery scenarios. A disaster recovery launch reservation (DRLR) is a reservation of a given unit of compute capacity that is unique to a source geographic area (that is, a defined area of the service provider network containing computing resource(s) for which a user desires to obtain backup compute capacity) and a destination area (that is, a defined area of the service provider network at which the reserved compute capacity is located), where other users can reserve the compute capacity relative to other source geographic area-to-destination geographic area mappings.

    Abstract: Techniques for private network mirroring are described. Users can select one or more existing private networks to be mirrored in the same or different network area. Any network configuration changes made in the selected private network (e.g., “master” private network) can be propagated automatically to the mirror private network. This enables users to utilize resources in another network area for disaster recovery, ensuring that the network configuration of the mirror private network is consistent with the master private network through real-time updates. Additionally, users managing infrastructure that includes multiple private networks can select one master private network and propagate configuration changes to other private networks, reducing management overhead incurred by these multi-private network installations.

    Abstract: Various systems, processes, and techniques may be used to allocate computer resources. In particular implementations, systems and processes for allocation of computer resources may include the ability to determine whether a request for allocation of computer resources has been received and determine a set of server computers able to fulfill requirements of the request. The systems and processes may also include the ability to identify one or more server computers in the set likely to successfully provide the computer resources and allocate the requested computer resources on an identified server computer.

    REAL-TIME DATA VALIDATION USING LAGGING REPLICA DATABASES

    Abstract: A real-time data validation system prevents problematic updates from being replicated from a primary database to a replica database. The data validation system may inject a time delay into the replication process, so that when an update in a replication stream fails a specified data validation, the data validation system will prevent the update from being applied to the replica. The replication process may be halted to take snapshot of the replica database during the halt, and resumed after the snapshot. Accordingly, if the problematic update is later confirmed to be invalid, the replica database can be rolled back to a point before the problematic update. Advantageously, the disclosed system can be used to implement a variety of data validations on top of a database replication process to protect the replica database from receiving undesired updates.
