The SDDC and the Cloud are going to require a new SDDC Management Stack that will need to be based upon a multi-vendor big data datastore. There will likely be on-premise and cloud hosted version of these datastores. Splunk, VMware, New Relic, The Pivotal Initiative, CloudPhysics, AppNeta, and Boundary are all excellent hypothetical suppliers of such a datastore.
If you are running business critical or performance critical applications in shared (virtualized or in a public cloud) environment then you might need big data operations management. If your environment is large enough to make monitoring into a big data problem, then choosing a product from a vendor like CloudPhysics, Reflex Systems, Splunk or Xangati might be a good choice..
