Rather than trying to find a workable middleware to bring it together, companies like Virtual Global have cloud solutions that make this process simpler.
Older middleware (the point between big computers and applications) is increasingly part of the cloud infrastructure, and end points like phones and laptops now choose, manage and load applications, with or without approval from corporate IT departments.
In hybrid form, a private cloud can include data stored on premise or off, with a private Platform-as-a-Service middleware layer managing application data and enforcing data security.
