In a dynamic economic environment, a company’s survival may depend
on its ability to focus on core business and adapt quickly.
As the business adapts to changing government and industry
regulations, and anticipates competitive threats, IT needs to help the
business find new ways to respond.
Cloud computing is a business and economic model. For
business agility and economic reasons, the cloud is becoming an
increasingly important option for companies.
What is Cloud Computing?
The CLOUD in cloud computing provides the
means through which everything —
from computing power to computing
infrastructure, applications, business processes
to personal collaboration
— can be delivered to you as a service
wherever and whenever you need.
Characteristics of Cloud
Multitenancy (Shared Resources): Multiple users use the same
Massive scalability: Ability to scale to thousands of systems.
Elasticity: Users can rapidly increase and decrease their computing
resources as needed, as well as release resources for other uses when they
are no longer required.
Pay as You Go: Users pay for only the resources they actually use and
for only the time they require them.
Self-provisioning of Resources: Users self-provision resources, such
as additional systems (processing capability, software,storage) and network
Components of Cloud
The cloud itself is a set of hardware, networks, storage,
services, and interfaces that enable the delivery of computing as a
The world of the cloud has lots of participants:
The end user doesn’t really have to know anything about the
Business management needs to take responsibility for overall
governance of data or services living in a cloud.
The cloud service provider is responsible for IT assets and
Types of Clouds
The services and infrastructure are provided off-site over the
These clouds offer the greatest level of efficiency in shared
A public cloud is the obvious choice when:
Applications are used by lots of people.
Need to test and develop application code.
Need incremental capacity (the ability to add computer capacity
for peak times).
For collaboration projects.
2. Private Cloud
- The services and infrastructure are maintained on a private
- These clouds offer the greatest level of security and control.
- A private cloud is the obvious choice when:
1. Your business is your data and your applications.
2. Your business is part of an industry that must conform
to strict security and data privacy issues.
3. Your company is large enough to run a next generation
cloud data center efficiently and effectively on its own.
3. Hybrid Cloud
- Includes a variety of public and private options with multiple
- By spreading things out over a hybrid cloud, you keep each aspect
at your business in the most efficient environment possible.
- Have to keep track of multiple different security platforms.
- You can use a public cloud to interact with the clients but keep
their data secured within a private cloud.
