Increasing resource utilization in cloud computing clusters

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, wherein the program instructions are executable by a processor to cause the processor to conduct a method comprising:

• receiving a request to create a cloud computing cluster, the cloud computing cluster comprising a clustered filesystem and a requested number of processing nodes and attached storage devices associated with the cloud computing cluster;
• initiating an initialization process for a single processing node and a corresponding attached storage device responsive to receiving the request to create the cloud computing cluster;
• previous to completion of the initialization process, requesting and receiving an IP address for the single processing node to produce a received IP address and a device ID for the corresponding attached storage device from one or more cloud infrastructure controllers to produce a received device IP;
• previous to completion of the initialization process, configuring the clustered filesystem and a corresponding WAN cache using the received IP address and the received device ID;
• and
• conducting a computing cluster termination process responsive to receiving a request to terminate the cloud computing cluster, wherein the computing cluster termination process comprises:
• determining changes to data captured in the WAN cache;
• committing the changes to local storage or a remote site;
• identifying processing nodes and corresponding attached storage devices associated with the cloud computing cluster;
• and
• releasing the processing nodes and corresponding attached storage devices.
