for light workloads, 64 for
medium workloads and 27 for
heavy workloads); x86 cloud
configuration needed a total of
11 x86 systems each with 24
3.0 GHz cores, 512 GB memory
and 7x400 GB SSDs; z13 cloud
configuration needed total of
32 IFLs, 3806 GB memory and
Storwize* V7000 with 47x400
GB SSDs. 
Based on the system
configurations determined, the
three-year TCO was calculated
for z13 cloud, x86 cloud and
public cloud. A comprehensive
TCO model was built, taking
more than 30 cost variables into
consideration. For each platform,
the cost variables are placed
in the following categories:
infrastructure, middleware, and
labor, power and space (see
Figure 2, page 12).

costs for labor, electricity and
floor space work out to be lower
than with an x86-based cloud.

An Optimal Platform
The z13 system is designed
to deliver an optimal, secure

cloud platform to host a
variety of demanding enterprise
workloads at a very competitive
TCO. It offers numerous
key features that are difficult
to find in competing cloud
solutions.

bidirectional data replication

Results
The three-year TCO for the z13
cloud is 32 percent less costly
than an x86-based private cloud
and 66 percent less costly than a
typical public cloud deployment
(see Figure 3, page 13).
On z13, the workloads can be
virtualized on a smaller footprint,
which results in much lower
overall middleware costs when
compared to other alternatives.
Middleware costs become a
dominating factor of the total cost
of x86 cloud and public cloud.
For a z13 cloud, middleware costs
for this case are 77 percent lower
than middleware costs on an x86
cloud and 90 percent lower than
middleware costs on a public
cloud (see Figure 4, page 14).
This is because on an x86 cloud,
middleware is priced per physical
core and on public cloud the
middleware is priced per virtual
CPU (vCPU) where each vCPU is
assumed to be a hyperthread of
a physical core. Further, with the
z13 cloud's smaller footprint,
