Many companies rely upon Return on Investment (ROI) when making technology strategy decisions, but few take the time to actually determine how much that strategy will cost over time. That's unfortunate, because without estimating the Total Cost of Ownership (TCO), ROI is meaningless. There's no way of knowing how large an investment is actually being made.
That's particularly true when companies decide whether to use an IT hosting provider or take the do-it-yourself route; Buy v. Build. Because managed hosting is presenting a complete solution, all costs are on the table from the start. By contrast, in-house hosting often involves hidden costs that aren't surfaced until the do-it-yourself project is well underway.
Hidden cost when trying to ‘build’ an infrastructure will be buried in three phases; Capital Expenditures (CAPEX), Hardware Deprecation and overall infrastructure maintenance.
With the introduction of Public Cloud and Private Cloud infrastructures, it truly allows for a more SaaS based SharePoint deployment with better utilization of resources and Global deployments.
