Delta offers customized solutions in all shapes and sizes, delivered via the cloud, on premise, or some combination of the two.
Premise-based solutions are traditional, customer-owned and managed, with all hardware, software and management tools physically located at a customer facility. The solutions are typically favored by enterprises with their own IT staff, a need or desire for more direct control of the IT environment, and prefer capital expenses over ongoing, operational expenses. A common example is K12 environments where funding typically comes from bond issues and uncertainty between the next round of funding is unpredictable. Thus, the need to own the equipment for 7-10 years is the norm.
Cloud and Managed Services offerings are often desirable for those lacking their own IT staff, with distributed locations and seek a predictable operational cost instead of a larger capital outlay. In these cases, solutions can be constructed and managed in private or public clouds, with support for the infrastructure provided by the service provider.
Hybrid solutions are simply a combination of the above. Examples include enterprises with a physical headquarters but many remote branch offices, or those that which to keep some aspect of their enterprise on premise (e.g., network switches), but wish to have their voice system or some applications delivered as a service.
