Cloud Computing Definition and Solutions.
What is cloud computing?
What are the different types of cloud computing?
• Infrastructure as a Service
• Platform as a Service
• Software as a Service

How does Cloud Computing affect Business Processes?
Platform as a Service (PaaS)
Provides virtualized servers on which users can run existing applications or develop new ones without having to worry about maintaining the operating systems, server hardware, load balancing or computing capacity.

With PaaS, features can be changed and upgraded frequently.

Geographically distributed development teams can work together on software development projects.

Services can be obtained from diverse sources that cross international boundaries.

Initial and ongoing costs can be reduced by the use of infrastructure services from a single vendor rather than maintaining multiple hardware facilities.

Overall expenses can also be minimized by unification of programming development efforts.
Infrastructure as a Service (IaaS)
A provision model in which an organization outsources the equipment used to support their operations and is designed to augment or replace the functions of an entire data center.

This includes storage, hardware, servers and networking components.

The service provider owns the equipment and is responsible for housing, running and maintaining it.

The client typically pays on a per-use basis.

Done through desktop virtualization and requires internet connectivity.
How does Cloud Computing affect the collection, storage, and use of data?

What are the Cost and benefits of this technology?

Quick Deployment
Almost instantaneous
Metered Cost
Pay-as-you-go approach means a more efficient approach to IT
Little or no capital investment
No depreciation expense in future years
Little or no maintenance cost
Maintenance, if any, is done remotely through a workstation or configuration screen
Lower costs
Vendors provide lower costs by buying in bulk and amortizing costs over more customers
Lower per-unit cost savings are handed down

What are the risks of this technology?

Data mobility
Data is not easily transferred to other software

Although stated in the contract, it is still unknown if your data is actually private

Service Levels
Cloud computing is yet not designed to be tailored exactly to your business

Applications within the cloud are not usually compatible with those running within the organization’s firewall

Software as a Service (SaaS)
SaaS is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.
The most widely known and widely used form of cloud computing.
Who can give me an example of this? (Hint we all use it)
SaaS provides all the functions of a sophisticated traditional application, but through a Web browser, not a locally-installed application.
SaaS eliminates worries about app servers, storage, application development and related, common concerns of IT.
There are two slightly different delivery models for SaaS.
The hosted application management (hosted AM) model is similar to ASP (Application service Provider): a provider hosts commercially available software for customers and delivers it over the Web.
In the software on demand model, the provider gives customers network-based access to a single copy of an application created specifically for SaaS distribution.

Logical Areas of Responsibility for Implementing Security Controls
How does Cloud Computing affect the collection, storage, and use of data?
Data Collection
Reduces redundancy of data
Data Storage
-You don't need to carry around a Physical Storage Device
-You don't need to use the same computer to save and retrieve information
Alternative to back-up data
Data Use
Allow you to share your data with others

A. What is Cloud Computing?
B. Different Types of Cloud Computing
C. Cloud Computing and Business Processes
D.Collection, Storage, and Use of Data
E. Benefits and Risks

Little or no capital investment
No tax savings from depreciation expense in future years
Underdeveloped monitoring and maintenance equipment
Recent announcements to provide better control over data
Immature standards
Although standards are currently a work in progress, it is still years away
Interoperable management, data migration, security, etc
If you're unsure about what Cloud Computing is, you are probably among the 95% of people that are already using cloud services.

Real life examples of Cloud Computing:
>online banking
>social networks

Cloud Computing is the use of hardware and software to deliver a service over a network (typically the Internet).

With cloud computing, users can access files and use applications from any device that can access the Internet.

Storage and Collection of Data
Steps to Modify an Organization's Information Systems
• Determining what type of cloud computing the organization needs
• Application modification or complete re-architecting
• Data Concerns
• Assessing the Level of Customer Service Offered
• Developing an Exit Strategy
