Here at Mythics, we talk a lot about “Information Technology as a Service”, but what does that mean? It’s a new (and we think valuable) way of approaching how you consume IT services. Three key elements of ITaaS are:

-Business Focus: Defining what functionality is required, along with how fast it must be and what reliability (up time, data backup and recovery requirements) and security requirements are necessary. IT personnel are used to doing this by conducting sizing exercises, and then specifying a certain number of processors, memory, storage appliances, network bandwidth, etc. Cloud services have greatly multiplied the options for providing these functions, so IT or contracting officers have an increasingly difficult time specifying the most effective components. By sticking to the business requirements the system must meet (provided by the business users) they can let the market provide the best solutions.

-Paying as Service is Delivered:  Often this is a discussion of Capital Expenses versus Operational Expenses, but it can also simply be a cash-flow issue.  By spreading costs out over time, it becomes easier to budget for organizational IT requirements. It also makes the Total Cost of Ownership easier to compute and compare for various options in order to find the most appropriate services.

-Provider Handles the Details: I often find customers wanting to get involved in the actual service delivery.  Usually with security more than the core applications, but in either case they are substituting the theoretically more efficient cloud provider personnel and processes with their own. This can erode the benefit of contracting for ITaaS in ways that are often difficult for customers to measure, so avoid the temptation to meddle with the “how.”

Some people have categorized ITaaS as a “SaaS” way of thinking—find the right complete solution and purchase that—but it can also work at lower levels of the stack. For instance, you may only require a database or middleware service, but just defining what functionality to deliver will result in a more complete set of options (at likely better prices) than trying to specify one specific method of delivery. Mythics can help you analyze your business requirements and provide comparative analyses to demonstrate how this can help you.  Just call and ask for a Cloud Assessment today!
