Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. There are three main service models of cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). There are also four deployment models of cloud computing: private cloud, community cloud, public cloud, and hybrid cloud. Building a cloud requires key components like network infrastructure, servers, operating systems, hypervisors, cloud management platforms, data center design, and generators for high availability.

3. Cloud Computing Definition - Continued

4. • Cloud computing is a new way of delivering computing resources, not a
new technology.
• Cloud computing is a pay-per-use model for enabling available,
convenient, on-demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage, applications,
services) that can be rapidly provisioned and released with minimal
management effort or service provider interaction- NIST
Cloud Computing Definition

5. In General:
•Cloud computing is a technology that uses the
Internet, central remote virtual servers to maintain
data and applications.
•Cloud computing allows consumers to use
applications without installation and access their
personal files at any computer with Internet access
anytime anywhere

• “Delivering hosted services over the Internet.”
• “The Infrastructure of the future.”

IaaS: Infrastructure as a Service
Consumer can provision computing resources within provider's infrastructure
upon which they can deploy and run arbitrary software, including OS and
applications.
PaaS: Platform as Service
Consumer can create custom applications using programming tools supported by
the provider and deploy them onto the provider's cloud infrastructure
SaaS: Software as Service
Consumer uses provider’s applications running on
provider's cloud infrastructure

11. Deployment Models
• Private Cloud : The cloud managed by a specific organization.
• Community Cloud : The cloud infrastructure is shared among a number of
organizations with similar interests and requirements, such as science
laboratories, universities, etc.
• Public Cloud : The cloud infrastructure is available to the public on a
commercial basis by a cloud service provider.

12. Deployment Models - Continued
• Hybrid Cloud — The cloud infrastructure consists of a number of clouds of
any type, but the clouds have the ability through their interfaces to allow
data and/or applications to be moved from one cloud to another.

14. • Cutting cost: Pay as you go model
• Saving time: Machines can be deployed and configured
within Few minutes.
• Scalability: Increase or decrease the machine
capabilities depending on the need.
• Availability: Access the service anytime anywhere.
• Reliability : Intangible downtime.
Cloud Benefits

15. Technology Roadmap To Cloud
• Service oriented architecture
infrastructure
• Rapid provisioning of IT
resources, massive scaling
• Dynamic service mgmt
• Energy saving via auto
workload distribution
• Consolidate IT assets &
datacenters
• Standardize and centralize
management
• Energy saving - Phase out
inefficient HW
• IT assets & datacenters
kept growing
• Desperate system tools
• Inconsistent processes
• Soaring IT and power costs
• Virtualized infrastructure -
increased system utilization
• Unify virtual & physical mgmt
• Promote resource sharing across
organization
• Energy saving – maximize effective
use
