3. EXECUTIVE SUMMARY
By any measure, the hype around Cloud computing has reached nearly deafening levels. However, behind the wall of hype lies
a fundamentally straightforward concept — one that’s been percolating for many years in the IT world. Cloud computing is an
architecture that enables IT organizations to parcel out portions of a shared pool of hardware and so ware resources to users
through an automated, self-service request system.
This model for IT, internally managed and externally hosted, offers tremendous benefits in the areas of cost-savings, IT
responsiveness, and improved flexibility. However, its successful implementation typically requires organizations to overcome some
significant organizational and technological hurdles.
BMC So ware delivers solutions and expertise to clear these barriers, from the planning stages to the optimization and governance
of a working Cloud. The payoff, in the end, is a transformed infrastructure that is flexible, highly responsive to business needs, cost
effective, and unified.
DREAMING OF CLOUDS: THE SKY HIGH GOAL
Cloud computing is driving a great deal of IT investment. IT groups are seeking to give greater access to resources to their
stakeholders, respond with agility to the needs and demands of the business, and at the same time, curtail costs. Clouds come in a
variety of flavors, including:
» So ware-as-a-Service (SaaS): Targeted at end users seeking to purchase applications, SaaS hosts those applications for the
user and charges a subscription fee.
» Platform-as-a-Service (PaaS): Designed for developers, PaaS hosts all the building blocks of a development environment,
speeding up the development process and encouraging support for a platform.
» Infrastructure-as-a-Service (IaaS): Comprised of the foundations of any IT environment, IaaS is the most fundamental type of
Cloud, delivering operating systems and application stacks to internal or external customers.
Fundamentally, a few core elements are required of an IaaS Cloud:
» A self-service portal, enabling users to request and receive configured resources rapidly
» An automated provisioning model, facilitating the creation of flexible, multi-tiered VMs to meet the specific needs of the user
» A service-model, extending the traditional model of Business Service Management to the Cloud, and bringing with it the best
practices that ensure service quality
» A dynamic management environment that can actively monitor and respond to this ever-changing set of workloads in a way that
optimizes service quality and cost
This definition applies equally to private Clouds and public Clouds. Public Clouds are designed to sell capacity to companies with
limited internal resources. Private Clouds mimic the same structure, but exist within the company’s datacenters, delivering flexibility
and some cost-savings without leaving the walls of the organization. Hybrid Clouds are an amalgam of both, in which companies
reach out to public Clouds to extend their own infrastructures, but manage them seamlessly. Finally, the concept of a community
Cloud has been developed to describe coalitions of organizations, typically governmental or of the same type, who build a shared,
secure external Cloud together.
The ultimate goals of all these environments are:
» More efficient use of resources, whether financial, physical, or human
» Improved agility and flexibility, removing the IT barrier from business efficiency
» Expanded service orientation, aligning IT and business goals more directly

While the concept of Cloud computing is reasonably straightforward, the execution does Concur Technologies embraced BSM

and approvals, and finally, provisioning the resources presents a complex orchestration
challenge far beyond “copy and paste.” Specifically, organizations usually desire that (source: www.cio.com/article/506114/Inside_
One_Firm_s_Private_Cloud_Journey)
the available service offerings be driven by user roles and constrained by security,
organizational, or financial policies.
» Second is the dynamic management challenge. Once commissioned, Cloud resources
have tremendous flexibility to grow, shrink, move, change configurations, and ultimately,
be decommissioned. This process mirrors that of a traditional physical datacenter, infused
with a host of additional degrees of freedom (and thus, complexity). As such, it requires
much of the same management best practices — augmented with Cloud awareness.
Absent that, conditions will occur for which appropriate responses and controls are
not well established, and the organization will experience increased costs, decreased
availability, and reduced flexibility. In fact, organizations need to view Cloud as a catalyst
for improving their IT maturity.
» Third is the challenge of scope. Born of the virtualization world, Cloud computing is o en
perceived as being uniformly based on x86 Microso Windows and Linux platforms;
while, in fact, this is not at all reflective of the reality of the modern datacenter. Companies
continue to be broadly multi-platform in their datacenters, running everything from blade
servers to mainframes and leveraging a host of virtualization technologies, including
hypervisors, Solaris™ zones and containers, and even LPARs. To limit the Cloud to a
subset of the company’s systems is to hamper its strength and curtail its eventual growth.
» Finally, a diverse group of public Clouds are being built by telecommunications firms and
service providers the world over. Enterprises are increasingly seeking opportunities to
leverage these external Clouds both for cost-savings and increased flexibility. However,
the provisioning and management of those resources o en represent a separate
IT challenge —one that, realistically, should be a seamless extension of the private
Cloud, managed with consistent processes, policies, people, and tools. Thoughtful
organizations, while embracing the benefits of public Cloud usage, are not willing to do so
at the price of introducing new management silos.
To implement and be successful developing a Cloud computing infrastructure, organizations
should consider every stage of the environment — from planning and provisioning to
operations and decommissioning. By adopting a layered approach, the fundamentals
of management can be implemented, and then improved upon, generating increasing
efficiencies and flexibility for the business.

CLOUD GOVERNANCE
Cloud governance enables IT organizations to operate their Cloud environment like a
business. Organizations need the ability not only to calculate the costs associated with
delivering services, but also to optimize resource utilization in the environment and
ensure that compliance requirements are consistently and efficiently met. By linking an
understanding of service costing with Cloud service level definitions, utilization, capacity
investment, and public Cloud pricing, decisions can all be driven by — and aligned to —
the priorities of the business. The Cloud environment, private or hybrid, must create the
flexibility to address the needs of the business, while at the same time, optimize its own
operations to ensure costs and investments support business goals.
» IT service costing marries detailed information about the workloads in the Cloud with
costs associated with hardware, network, so ware, and other relevant resources. By
