Generally, cloud integration with CloudStreams provides you comprehensive connectivity options to Salesforce. You get easy outbound integration with partner SOAP apis and REST bulk apis. For inbound integration, you get streaming notifications capability. You also get connectors enabling Salesforce chatter and wave connectivity. You can also set policies and actions on inbound webservice invocations along with SaaS goverance capability. These are some general pointers on CloudStreams usecases. PM, Sales and marketing team can advise you more on these points.
Thanks
