1. A computer-implemented method comprising:
providing a primary data center, the primary data center comprising a primary source database system and a primary target database system, wherein a function is activated in the primary data center causing the primary target database system to:
comprise a copy of data of the primary source database system;
receive analysis queries from the primary source database system; and
execute the analysis queries on the data; and

in response to detecting a failure in the primary source database system:
offloading queries intended for the primary source database system to a secondary source database system, the secondary source database system of a secondary data center further comprising a secondary target database system, the secondary source database system comprising a copy of the data, wherein the function is deactivated in the secondary data center;
responsive to the primary target database system being available:
receiving, by the primary target database system, analysis queries, processed by the secondary source database system, of the offloaded queries; and
copying, by the primary target database system, the data to the secondary target database system; and

causing the function to be activated in the secondary data center.
