Method and devices for dynamic management of a server application on a server platform

A management center, comprising a processing unit for executing a computer program, for managing a server platform, the server platform having a maximum processing capacity available of which fractions are reservable for processing a plurality of server applications running on the server platform, wherein a first capacity fraction of the maximum processing capacity is assigned to a first server application and a second capacity fraction of the maximum processing capacity is assigned to a second server application, the management center operative to:

• receive an indication for a service on the server platform;
• obtain that the service is not covered by the first server application and the second server application, but instead covered by a third server application;
• determine a processing capacity required to process the third server application on the server platform;
• determine that the first capacity fraction or the second capacity fraction needs to be reduced, in order to accommodate the processing capacity required for the third server application;
• check, in a look-up table, priorities associated with the first server application and the second server application, wherein the priorities are associated with Quality of Service (QoS) assigned to respective server applications;
• in response to checking the priorities, determine that the first server application can tolerate a reduction in QoS;
• reduce the first capacity fraction as a consequence of determining that the first server application can tolerate the reduction in QoS;
• assign a third capacity fraction of the maximum processing capacity to the third server application for installing the third server application on the server platform;
• generate a first management command to assign the reduced first capacity fraction to the first server application on the server platform;
• generate a second management command to assign the third capacity fraction to the third server application;
• generate a third management command to install the third server application on the server platform;
• and
• send the first, second and third management commands to the server platform to reduce the first capacity fraction, assign the third capacity fraction to the third server application and install the third server application on the server platform.

A non-transitory computer readable storage medium storing executable instructions, which when executed by a processor of a management center managing a server platform, the server platform having a maximum processing capacity available of which fractions are reservable for processing a plurality of server applications running on the server platform, wherein a first capacity fraction of the maximum processing capacity is assigned to a first server application and a second capacity fraction of the maximum processing capacity is assigned to a second server application, cause the management center to perform operations comprising:

• receiving an indication for a service on the server platform;
• obtaining that the service is not covered by the first server application and the second server application, but instead covered by a third server application;
• determining a processing capacity required for processing the third server application on the server platform;
• determining that the first capacity fraction or the second capacity fraction needs to be reduced, in order to accommodate the processing capacity required for the third server application;
• checking, in a look-up table, priorities associated with the first server application and the second server application, wherein the priorities are associated with Quality of Service (QoS) assigned to respective server applications;
• in response to checking the priorities, determining that the first server application can tolerate a reduction in QoS;
• reducing the first capacity fraction as a consequence of determining that the first server application can tolerate the reduction in QoS;
• assigning a third capacity fraction of the maximum processing capacity to the third server application for installing the third server application on the server platform;
• generating a first management command to assign the reduced first capacity fraction to the first server application on the server platform;
• generating a second management command to assign the third capacity fraction to the third server application;
• generating a third management command to install the third server application on the server platform;
• and
• sending the first, second and third management commands to the server platform for reducing the first capacity fraction, assigning the third capacity fraction to the third server application and installing the third server application on the server platform.
