Abstract: Methods, systems, and apparatus, including medium-encoded computer program products for recovery procedures on a multiple availability zone cloud platform include: executing requests from a red button agent to a red button service to obtain red flag statuses that are relevant for outages of components defined for a cloud platform, wherein the red button agent is installed at a first cloud component instance running at a first zone of the cloud platform including multiple availability zones; in response to receiving a red flag status from the red button service for the first cloud component instance, determining that the first cloud component instance is associated with an outage; and executing a recovery procedure for the first cloud component instance.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products for recovery procedures on a multiple availability zone cloud platform include: identifying a selection of a flag from a set of flags defined at a cloud platform including multiple availability zones, wherein the flag is selected to identify an outage at a first zone of the cloud platform, and wherein each flag of the set of flags is mapped to an entity from a plurality of entities defined for the cloud platform; determining one or more entities from the plurality of entities defined for the cloud platform associated with recovering the outage based on identifying an entity corresponding to the selected flag; and in response to determining the one or more entities associated with recovering the outage, initiating a recovery procedure to reconfigure communication flows at the cloud platform associated with the determined one or more entities.

Abstract: Account data comprising metadata for primary application instances running at a primary active cloud environment instance (ACEI) is stored. Application data associated with the primary application instances is stored at primary databases (DBs). The account and application data are transferred to secondary DBs at a secondary ACEI. The secondary ACEI may be a backup instance to substitute services provided by the primary ACEI in case of unavailability. For example, the location where the primary ACEI is hosted may be affected by a disaster. To failover a primary data center hosting the primary ACEI, a database takeover to the secondary DBs is performed. The secondary ACEI is configured correspondingly to the primary ACEI based on the transferred account data. Secondary application instances corresponding to the primary application instances are started at the secondary ACEI. Requests directed to the primary application instances are redirected to the secondary application instances.
