Cloud computing involves linking many computers together over the internet to form a large virtual computer. It provides access to computer resources and services via the internet rather than hardware and software locally installed. There are three main categories of cloud computing: Infrastructure as a Service (IaaS) provides virtual servers and storage; Platform as a Service (PaaS) provides development environments; and Software as a Service (SaaS) provides access to apps already in the cloud. While cloud computing offers benefits like flexibility and cost savings, it also presents disadvantages such as security risks and lack of control.

1. CLOUD COMPUTING

2. Linking many computers together to form
one very big computer used to perform
all your tasks on the Internet.

3. What is Cloud Computing?
• Using web apps or server services
you pay to access instead of software
or hardware you buy and install.
• Computer services delivered via the
Internet covering more than apps &
data storage.

5. Cloud Computing Categories
• Infrastructure (IaaS)
• Platform (PaaS)
• Software (SaaS)

6. 1) Infrastructure as a Service
Provides users with virtual
infrastructure like servers and data
storage space. This is where
virtualization fits into the cloud.

7. Virtualization
Good News: Allows expansion of IT
resources without incurring costs of
physically expanding infrastructure.
Bad News: Be patient. Stay tuned!

8. 2) Platform as a Service
Provides users with development
environment services where they
create and run home-grown apps.

9. 3) Software as a Service
Provides users with access to apps
already operating in the cloud.

10. Cloud Computing Adds Up…
…when SaaS (Software as a Service) is
combined with PaaS (hardware Platform).
SaaS & PaaS describe the business model
of users logging into a centralized hub to
access their software products.

11. No current regulations for data
security risks that would punish
companies gambling with massive
amounts of sensitive data.

12. Cloud Computing Disadvantages
• Security
• Downtime
• Cost
• Inflexibility
• Lack of support
