Infrastructure-related TCO Savings
Reductions in Infrastructure costs account for approximately 60% of the TCO savings and include
reductions in software licensing fees, device maintenance and support fees, and server and storage
costs. The majority of the infrastructure cost reductions is provided by the elimination of the mobile
device maintenance and support fee, as shown in Figure 2.

Previous Wipro research found that RIM solutions that provide mobile access to Microsoft Exchange Server places additional burden on the underlying Microsoft SQL
database that requires an additional SQL server for every 3,400 blackberry devices supported.
The RIM solution has a licensing model that assesses annual maintenance fees on servers and on each
mobile device under management. The RIM TCO included maintenance and support costs based on
RIMs T-Support level 4, which was discounted based on RIM’s published volume price discounts. MDM
does not have a comparable per device maintenance or support fee and the resulting savings accounts
for 28% of the 1 year TCO savings and 40% of the 3 year TCO savings.
The RIM server conguration assumed a Blackberry Enterprise Server would be required for every 1,300
mobile devices. The RIM server conguration also included additional Microsoft SQL Servers
3
and
storage; although technically required, the solution did not include the additional Exchange Back End
Servers unique to this particular application. The server-related costs included the cost of the hardware,
storage, hardware maintenance, and facilities.
The MDM solution supported up to 15,000 users and was based on a three server conguration that
consisted of a gateway server, enrollment server and DM server. At 10,000 users, the number of gateway
servers was increased from three to seven.
Server-related cost savings represented 14% to the 1 year TCO and 8% to the three year TCO.
The remaining infrastructure savings reects MDM’s lower software licensing fees relative to RIM.
Software license fee savings accounted for 19% of the one year TCO reduction and 9% of the three year
TCO reduction.
