Much like the previous application methods, Eucalyptus installation may differ Using the reason and complexity of the desired IaaS System (deployment simplicity, overall performance or substantial availability). All Eucalyptus factors have to be put in on sixty four-bit architecture Bodily equipment (not virtual devices) with synchronized clocks. It is achievable to setup the Cloud Controller, Walrus, Cluster Controller and Storage Controller on one particular equipment and a Node Controller on one or more equipment. Alternatively, one can set up Each individual component on an impartial Bodily server which supplies Every part maximal area useful resource utilization.
