ROLES AND SECRETS OF IAAS (INFRASTRUCTURE AS A SERVICE)
FOR CLOUD COMPUTING

ABSTACTION - We need to drill into specific
characteristics, to define Infrastructure as a Service
(IaaS). A cloud platform[1] provider must provide
infrastructure as a Service. This has been no easy task as
nearly every cloud platform provider has recently services
designed and promoted features to address the IaaS and
cloud computing market. A definition of cloud computing
fortunately, as the technology has evolved has emerged
from the National Institute of Standards and Technology
that is composed [2] of five essential characteristics, three
service models, and four deployment models.
Key Words: IaaS, deployment, platform etc…
1. IAAS (INFRASTRUCTURE AS A SERVICE):
Infrastructure as a Service (IaaS) abstracts hardware
(storage, server, and network infrastructure) into a pool of
storage, computing, and connectivity[3] capabilities that are
delivered as services for a usage-based (metered) cost.
usually said as IaaS. The consumer takes responsibility for
operations and configuration of the guest Operating System
(OS), software, and Database (DB). Compute capabilities
(such as bandwidth, performance, and storage access) are
also standardized. Service levels cover the availability and
performance[3] of the virtualized infrastructure. The
consumer takes on the operational risk that exists above the
infrastructure by investing in more capital equipment,
traditionally by which companies meet their growing IT
needs. Today, competitive pressures continue to demand
improvements, despite growing numbers of users and
applications in quality of service.
1.2 Essential Characteristics IAAS:

IaaS goal is to provide a storage, flexible, and virtualized
operating environment that can become a foundation for
SaaS and PaaS. to provide a standardized virtual server,

On-demand self-service - A consumer can
independently and unilaterally provision computing
capabilities, such as network connectivity, compute
time and storage, as needed automatically without
requiring human interaction with each service’s
provider.
Broad network access - Capabilities are available
over the network and accessed through standard
mechanisms that promote use by heterogeneous thick
or thin client platforms.
Resource pooling -The provider’s computing
resources are pooled to serve multiple consumers using
a multi-tenant[4] model, with different virtual and
physical resources dynamically assigned and
reassigned according to consumer demand.
Rapid elasticity -Capabilities can be elastically and
rapidly provisioned in some cases to quickly and
automatically scale out and rapidly released to quickly
scale in.
Scale Units: The Private Cloud Reference
Architecture defines the private cloud pattern of a Scale
Unit. However, there is no specific predefined selection
or set of values that comprise a scale unit. The
determination is part of the private cloud planning and
design[5] process. A Scale Unit is a pool of storage,
computing and network resources that can be deployed

as a single unit or in bundles that allow both
extensibility and reuse or reallocate without physical
reconfiguration.
Examples of these resources are:
Compute – Blade servers, deployed by one or
more racks at a time.
Storage – Enterprise SAN, with disk capacity to
match compute capability.
Network – New access and distribution designs
to meet storage and compute requirements.
The architect should consider future availability as changes
in hardware architectures will influence Management Fabric
implementations over time, when selecting elements of a
scale unit. A scale unit should be sized to accommodate[3]
future growth over a period that is meaningful to the
business. Some businesses will plan on a quarterly basis
while others may forecast by fiscal year or more.

upgraded[6] and maintained without downtime to the
workloads running in the resource pool.
Putting It All Together: Private Cloud Infrastructure as a
Service is an evolution in the IT industry and it forms the
foundation of cloud computing for all cloud enabled
workloads. Designing for Infrastructure as a Service raises
the Maturity[2] level and IT Capability to realize cloud
capabilities in allowing the business to focus on objectives,
respond with agility and realize economies of scale.

3. CONCLUSION

2. RESOURCE POOLS
A resource pool is comprised of network, server and storage
scale units that share a common hardware and configuration
baseline[1] but does not share a single point of failure[5]
with any other resource pool other than the facility itself. A
resource pool could be subdivided further into Fault
Domains..
Fault Domains: The Physical Fault Domains pattern is
defined in the Private Cloud Reference Architecture. A fault
domain is a set of physical infrastructure with a common
configuration within a resource pool that does not share a
single point of failure with any other fault domain, in an
Infrastructure as a Service design.
Upgrade Domains: An upgrade domain is infrastructure
within a resource pool that can be taken offline, or

The promise of cloud computing has long been a new height
of convenience, rapidly and easily provisioned pay-per-use
computing resources which can automatically scale and
instantly to meet changing demands. Emerging at the
convergence of major computing trends such as serviceoriented architectures, virtualization[6] and standardization
of the Internet, IaaS comes closer than ever before to fulfill
that vision. IaaS is being deployed by world-class
organizations as well as aggressive SMBs. Companies that
effectively leverage the benefits of an IaaS environment may
be able to gain an edge in a rapidly evolving economy.
