Abstract

A data center, DC includes applications that are controllable by one or more computing entities external to the DC. However, when the DC becomes unavailable to the computing entities, the applications are no longer controllable by the computing entities, which is undesirable. Disclosed techniques include the DC determining, based on an indication that the apps are no longer controllable by the computing entities, that the applications are to operate in a disaster recovery mode. Disclosed techniques include causing an indication that the applications at the DC are to operate in the disaster recovery mode to be communicated to applications that are already executing at the DC when the determination is made and to applications that start to execute at the DC after the determination is made. Disclosed techniques also include a further DC providing a failover for the DC.

Dependent claims

A method of controlling applications at a data center, DC, the applications being controllable by one or more computing entities external to the DC, the method including:

at a computing system of the DC:
obtaining an indication that the applications at the DC are no longer controllable by the one or more computing entities external to the DC;
determining, based on the indication, that the applications at the DC are to operate in a disaster recovery mode;
and
in response to the determination:
causing an indication that the applications at the DC are to operate in the disaster recovery mode to be communicated to one or more of the applications at the DC that are already executing at the DC when the determination is made;
and
causing the indication that the applications at the DC are to operate in the disaster recovery mode to be communicated to one or more of the applications at the DC that start to execute at the DC after the determination is made.

A method of controlling applications at a data centre, DC, the applications being controllable by one or more computing entities external to the DC, the DC including a computing system that determines, on the basis of an indication that the applications at the DC are no longer controllable by the one or more entities external to the DC, that the applications at the DC are to operate in a disaster recovery mode, the method including:

at each of one or more of the applications at the DC that are already executing at the DC when the determination is made:
obtaining an indication, caused to be communicated by the computing system of the DC, that the applications at the DC are to operate in a disaster recovery mode;
and
in response to obtaining the indication, operating the application in a disaster recovery mode;
and
at each of one or more of the applications at the DC that start to execute at the DC after the determination is made:
obtaining the indication, caused to be communicated by the computing system of the DC, that the applications at the DC are to operate in the disaster recovery mode;
and
in response to obtaining the indication, operating the application in a disaster recovery mode.
