Cloud computing represents an opportunity for enterprise and service provider
datacenters to become more agile and flexible by using self-service infrastructure
provisioning; automated, dynamic resource pooling and scaling; and consumption-
based metering to improve accelerate cloud infrastructure configuration, provisioning,
and life-cycle management. IDC
estimates that combined enterprise
and service provider spending on IT
infrastructure hardware and software
for cloud datacenters will total more
than $42 billion worldwide by 2017.
Integrated systems, such as the IBM
PureFlex System, pre-integrate and
optimize software stacks with
compute, storage, network, and
management software resources to
enable optimal performance of
mission-critical applications and
workloads. Many IT organizations are
using integrated systems as core platforms to enable private clouds and public cloud
service delivery environments.
IDC interviews with several IBM customers and partners show that organizations
using IBM PureFlex System, as well as Flex System infrastructure building blocks, as
the infrastructure platform for cloud realized over $640,000 in benefits related to
improved infrastructure deployment, performance, and operational economics.
Specifically:
 Faster system deployment: Pre-integrated systems optimized for either
general-purpose or specialized workloads were able to improve system ordering,
purchasing, and deployment by 33%.
 Faster service delivery: Service providers that had already deployed integrated
systems into their service delivery environments were able to activate new
customer services in minutes or hours rather than having to wait six weeks or
more to purchase, integrate, and deploy new service-enabling infrastructure.

 Enhanced system performance: Customers in the study realized close to
100% system availability as a result of reduced unplanned downtime, fewer
human errors, and faster resource provisioning and migration.
 Lower cost of operations: Improved IT staff productivity, lower facilities costs,
and reduced IT hardware spending the lowered cost of operations by 37%.

Increasing numbers of enterprise IT and service provider datacenter managers are
implementing dynamic self-service cloud architectures to improve IT infrastructure
performance, increase resource utilization, and enhance IT operations staff productivity.
IDC's research indicates that over 60% of datacenter server life-cycle costs are
associated with the cost of IT administrative staff. Integrated systems help reduce the
complexity of initial system ordering and sizing as well as simplify day-to-day operations,
particularly with regard to system firmware and software upgrades and patching because
updates can be applied as a single, pre-tested and pre-certified unit.
Built-in self-service provisioning automation and infrastructure configuration and
deployment patterns can further streamline day-to-day datacenter operations and
allow IT generalists to take on greater levels of operational responsibility. For many
enterprise IT organizations, integrated systems provide a rapid on-ramp to private
clouds, while service providers see integrated systems as a way to quickly launch
public cloud service delivery environments. A recent IDC survey found that 40% of
organizations that are using or considering integrated systems expect to implement
cloud self-service provisioning capabilities as part of the solution.

Integrated systems are specifically designed to provide more efficient and flexible
IT resources and management environments than can be enabled by traditional
datacenter architectures. This paper discusses how several IBM PureFlex and
Flex System customers and partners are using expert integrated platforms to reduce
the cost and improve the performance of cloud-enabled datacenters and services.

Capgemini was the first SAP Certified Global Cloud Partner. The company
implemented its first multi-tenant hosted SAP cloud service using the IBM PureFlex
System Enterprise Edition to support a highly integrated, scalable, and automated
infrastructure as a cloud service delivery environment.
As a service provider, Capgemini is very focused on the speed of service delivery and
the cost of IT infrastructure equipment and staff. In comparing traditional,
non-integrated alternatives with the integrated IBM PureFlex System, configured for
multi-tenant SAP support, Capgemini identified cost savings of as much as 30%.
At the same time, the company identified a 10–15% improvement in performance and
availability due to the customized Flex System system engineering and integrations.
Part of that performance improvement is attributable to the fact that the company
used the IBM PureFlex System purchase as an opportunity to upgrade to a new
generation of processors that provided better performance at a lower price. Cost
savings also resulted from the higher density of the IBM PureFlex System and related
reductions in datacenter floor space and power and cooling requirements.
Equally important, Capgemini found that the IBM PureFlex System could be deployed
and provisioned more quickly than traditional server and storage solutions that
required more extensive onsite integration and testing. The company was able to fully
activate the system, complete data and workload migrations, and go live
with customers in 8 weeks, rather than the 12 weeks it would have expected to need
using traditional solutions (a 33% time savings). Beyond the physical hardware
integrations, Capgemini benefited from creating SAP patterns and virtual appliance
templates to standardize and speed application deployments using built-in automated
provisioning tools.
In terms of day-to-day operations and customer support, Capgemini estimates that
faster application provisioning, improved compliance with configuration standards,
and reduced need for scheduled downtime and patching have collectively reduced
the IT staff time needed to support the SAP hosting environment by 15–30%.
Capgemini's SAP cloud hosting service has also benefited from the ability of the
IBM PureFlex System to monitor resource utilization and feed data to consumption-
based chargeback systems. This in turn allows Capgemini to reach new sets of
customers that want to pay for only the resources they actually use or that have
highly variable requirements over the course of a year. Over time, Capgemini may

incorporate IBM FlexSystem Manager self-service provisioning capabilities into
services offered to end users to provide a new self-service option. For now, however,
access to the self-service automation functionality is limited to Capgemini's staff.

Redcentric is a United Kingdom–based managed, hosted, and Internet service
provider. Recently demerged from Redstone, Redcentric delivers ISP and cloud
services to a wide range of U.K. organizations using multiple U.K. and international
datacenters. Redcentric implemented IBM Flex System as the core platform to enable
its infrastructure-as-a-service (IaaS) solution. Flex System helped reduce
Redcentric's datacenter footprint by moving the company away from heavy
dependence on dedicated physical servers. Savings came in many forms, including
energy cost reductions of up to 40% and reduced software licensing costs of as much
as 70% because fewer cores were required.
By freeing up datacenter facilities space and creating an environment where
workloads can be deployed more quickly and resources can be more easily shared,
Redcentric now has the ability to more quickly expand its business and bring on new
customers without having to build out new datacenters to support its cloud services.
The IBM Flex System investment was seen as highly transformative for Redcentric. It
allows the company to meet customer requests for hosting a wide variety of operating
systems and applications on a shared common cloud platform, in addition to being able
to offer an IaaS option to self-service customers. Using the IBM Flex System, Redcentric
is able to rapidly spin up new resources as customers demand them. Rather than having
to wait six weeks or more for availability of workloads on physical servers, Redcentric's
cloud service customers can self-provision virtual resources on the IBM Flex System in
minutes. The built-in IBM Flex System Manager capabilities have helped reduce
administration costs by up to 50% and cut system setup costs by as much as 66%.
Even more importantly, however, the flexibility of the system, along with built-in
automation, has allowed Redcentric to expand its service portfolio and take on a
broader range of business critical applications and services. Customers that might
have been nervous about a shared service environment are more confident given the
extent of validated integration, patterns of expertise, and hardware reliability that are
provided by use of the IBM Flex System.

Agilisys is a large United Kingdom–based IT, consulting, and business services provider
with a diverse customer base spanning the private and public sectors. The company
develops, hosts, and supports a variety of applications for its clients, including support
for central and local governments that are using Agresso ERP systems.
Agilisys offers several of its solutions as hosted services and currently relies on the IBM
PureFlex System to support two of its most important new hosted financial service
applications. Agilisys wanted a scalable, secure, and automated IaaS platform to support

these applications and selected IBM PureFlex System. The fact that IBM PureFlex
System could be ordered and shipped as a single integrated unit was particularly
important given the company's need to get these new capabilities to market quickly.
When evaluating options for supporting these financial service applications, Agilisys
considered using legacy equipment that was already available on the datacenter
floor. The company opted instead to invest in the IBM PureFlex System in part
because the older systems would have required time-consuming repurposing and
might not have fully satisfied several important security requirements.
Because the IBM PureFlex System was pre-validated and sized with compute,
storage, firewall, and networking technology that met the company's performance and
security specifications, Agilisys found the IBM PureFlex System to be very
economical to implement and manage on a day-to-day basis. The company was able
to avoid time-consuming and complex integration and testing activities and was able
to rely on existing staff to implement the system. Agilisys continues to operate the
IBM PureFlex System without needing to hire additional IT staff in part because the
firmware and software upgrades for all components are integrated and tested by IBM
before being applied. The IBM FlexSystem Manager and associated patterns of
expertise allow Agilisys staff to eliminate human error when deploying new VMs,
expanding the system, or adding new subscriber resources. Agilisys credits the IBM
FlexSystem Manager with improving IT staff productivity and helping ensure
consistent SLAs.

Based on analysis of several IBM PureFlex System and Flex System customers that
are currently implementing cloud solutions, IDC expects that future customers can
achieve the following benefits:
 Faster system deployments and upgrades due to improved automation, use of
pre-defined patterns of expertise, and access to self-service provision capabilities
 Faster service delivery because service providers are able to activate new
customer services more quickly
 Higher levels of performance and increased availability due to reduced unplanned
downtime, fewer human errors, and faster resource provisioning and migration
 Lower cost of operations due to improved IT staff productivity, lower facilities
costs, and reduced IT hardware spending
F a s t e r S y s t e m D e p l o y m e n t
Because integrated systems are configured and integrated prior to being shipped to
customers, onsite IT staff members are not required to invest time and effort in
completing onsite integration and testing. IBM PureFlex System customers reported
savings on the order of 33% in terms of the time needed for initial system
deployment. In one example, the time required shrank from 12 weeks to 8 weeks.

As organizations become more reliant on IT resources to run their business, the
potential financial damage caused by unplanned outages and performance
slowdowns becomes an unacceptable risk. Many companies profiled in this paper are
service providers and as such had very low downtime — less than one hour per year
— prior to implementing IBM PureFlex System or Flex System. With IBM PureFlex
System or Flex System, they were able to eliminate that hour of downtime.
L o w e r C o s t o f O p e r a t i o n s
Organizations in the study reported that IBM PureFlex System and Flex System
delivered a 30% higher price performance than the other solutions they evaluated.
The organizations were able to reduce their cost of operations by 37% by leveraging
IBM PureFlex System and Flex System to deliver higher levels of performance with
the inherent resource utilization, management, space, and power cost advantages of
an integrated solution (see Figure 1).

The ability to fully exploit the benefits of integrated systems for cloud infrastructure
depends on the IT organization being willing and able to embrace a standardized
services-centric view toward setting SLAs and providing resources. IT teams must be
able to work with business stakeholders to agree on standard configurations and
SLAs and then render those as templates or patterns that can be delivered on a
consistent, repeatable self-service basis. IBM PureFlex System and Flex System
provide customers with powerful management and automation tools, but not all
organizations are fully ready to exploit their potential. If IBM can help its customers
and partners realize the full value of their IBM PureFlex System and Flex System
investments, the company will be able to help many organizations transform their
datacenters and improve operational efficiency in cloud environments.
C O N C L U S I O N
Expert integrated systems are an important option for enterprises and service
providers that want to quickly and cost effectively implement cloud infrastructure
environments that make extensive use of automation, self-service provisioning, and
consumption-based chargeback or metering. The experiences of IBM's customers
and partners indicate the benefits can be significant if organizations recognize and
embrace the transformational nature of the IBM PureFlex System and Flex System
integrated, unified architectures.

IDC utilized its standard ROI methodology for this project. This methodology is based
on using in-depth interviews to gather data from 10 companies about their use of IBM
PureSystems and then creating a financial model.
The financial model quantifies the following elements of the companies' operations
and measures the financial impact of technology on those elements:
 IT infrastructure: Costs for hardware, software, facilities, power, and related
services
 IT staff productivity: The value of IT staff in support of the business (Increasing
IT staff productivity means reducing the time spent by IT staff in manual support
tasks or repair and replacement and freeing up staff time to contribute to
business activities.)
 End-user productivity: The value of end users of business applications
(Increasing end-user productivity is measured in two ways — increasing end-user
work output and reducing end-user time lost to unplanned downtime, help desk
issues, or other performance issues related to technology.)
 Business productivity: The value of business operations impacted by
technology (Measurement includes increasing revenue and/or reducing cost of
operations as a result of becoming faster to market or reducing unplanned
downtime or other negative impacts on operations.)

IDC uses a set of assumptions to calculate the benefits discussed previously:
 Time values are multiplied by burdened salary (salary + 28% for benefits and
overhead) to quantify efficiency and manager productivity savings.
 Downtime values are a product of the number of hours of downtime multiplied by
the number of users affected.
 The impact of unplanned downtime is quantified in terms of impaired end-user
productivity and lost revenue.
 Lost productivity is a product of downtime multiplied by burdened salary.
 Lost revenue is a product of downtime multiplied by the average revenue
generated per hour.
Because every hour of downtime does not equate to a lost hour of productivity or
revenue generation, IDC attributes only a fraction of the result to savings. As part of
our assessment, we asked each company what fraction of downtime hours to use in
calculating productivity savings and the reduction in lost revenue. IDC then taxes the
revenue at that rate.
Further, because IT solutions require a deployment period, the full benefits of the
solution are not available during deployment. To capture this reality, IDC prorates the
benefits on a monthly basis and then subtracts the deployment time from the first-
year savings.
