Upgrading software on a cluster of computerized devices










Image Number 8 for United States Patent #8151021.

A technique for upgrading software running on a cluster of computerized nodes. The technique involves running a first version of the software on each node of the cluster. The technique further involves installing a second version of the software on each node in place of the first version of the software during an installation period and after running the first version of the software on each node. The second version of the software installed on each node includes a first version side and a second version side. At least one node of the cluster runs (i) the first version of the software or (ii) the first version side of the second version of the software at all times during the installation period. The technique further involves running the second version side of the second version of the software on each node of the cluster after the installation period.
