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.

Multilevel disaster recovery

In one embodiment the present invention includes a system for transaction recovery in a distributed computing environment. The system includes a transaction log server, application servers, and resource servers. The transaction log server stores a shared transaction log. The application servers implement a distributed transaction application and accesses the shared transaction log when performing a transaction using the distributed transaction application. The resource servers store data and that operate with the application servers to access the data according to the transaction. If one of the application servers fails, another application server assumes responsibility for a portion of the shared transaction log that was previously accessed by the failed application server.

Distributed transactional recovery system and method

Example systems and methods of application construction for execution on diverse computing infrastructures are presented. In one example, an application descriptor comprising information regarding an application is received. Available computing machine resources for execution of the application are selected based on the information in the application descriptor. Software resources comprising the application are installed on the selected computing machine resources based on the information in the application descriptor. At least one of the selected computing machine resources and the installed software resources are configured for execution of the application based on the information in the application descriptor.
