Demystifying Cloud Computing
10. History of HD applications
To understand the evolution of cloud
computing services and applications in the
Help Desk industry, let’s look back a few
decades…
Demystifying Cloud Computing
11. History of HD applications
1990s:
Largely proprietary, client/server-based
applications, with customer-owned servers
and infrastructure. Large capital investment,
many support resources required. Significant
configuration and implementation, as well as
ongoing database maintenance.

13. History of HD applications
2000s:
Still mostly proprietary, client/server-based
applications, but several hosted solutions
emerged. Less costly customer infrastructure.
Investment focused on expenses for Internet
access, licenses, support. Reliance on hosting
provider for configuration, maintenance.

15. History of HD applications
2010s:
Increasingly cloud-based Software as a
Service (SaaS). Premise-based for
organizations needing increased security. Only
customer infrastructure costs are Internet
access and PCs or Macs. Investment focused
on expenses for licenses, support.

18. What is Cloud Computing?
Cloud Computing (consumer): storing
and accessing data and programs over the
Internet instead of a hard drive
• Consumer examples: Apple iCloud,
Microsoft OneDrive, GoogleDocs,
Amazon CloudDrive

19. What is Cloud Computing?
Consumer cloud services and
applications:
• Apple iCloud: Mail, Contacts, Calendar
• Microsoft OneDrive: Office Online
• Google Drive: Google Docs
• Amazon CloudDrive: Music, images,
Kindle content

20. What is Cloud Computing?
Cloud-based Operating System (OS):
• Chrome OS
• ChromeBoxes
• ChromeBooks
• ChromeBases
• And now: ChromeBits

21. What is Cloud Computing?
Cloud Computing (business): On-demand
network access to a shared pool of computing
resources that can be rapidly provisioned and
released with minimal management effort
• Business examples: Software as a
Service (SaaS), Platform as a Service (PaaS)
and Infrastructure as a Service (IaaS)
Demystifying Cloud Computing
22. What is Cloud Computing?
Infrastructure as a Service (IaaS): The
organization procures processing, storage,
networks, and other computing resources as a
service, rather than housing on site.
The organization may have some control over
the operating systems, storage and deployed
applications.
Much like our highway infrastructure…
Demystifying Cloud Computing
23. What is Cloud Computing?
Platform as a Service (PaaS): The
organization procures customer-created or
acquired applications created using tools
provided by the provider.
The organization has control over the
deployed applications.
Much like the vehicles that run on our
highways…
Demystifying Cloud Computing
24. What is Cloud Computing?
Software as a Service (SaaS): The
organization procures the ability to run the
provider’s applications on a cloud .
The organization does not manage or control
the underlying infrastructure or the
applications.
Much like the people and goods that
travel in the vehicles on the highways…

25. What is Cloud Computing?
Public Cloud: Provisioned for use by the
general public (off premise)
Public Cloud: Provisioned for exclusive use
by a single organization (on or off premise)

26. Federal Government considerations
FedRAMP:
The Federal Risk and Authorization Management
Program, or FedRAMP, is a government-wide program
that provides a standardized approach to security
assessment, authorization, and continuous monitoring
for cloud products and services.

27. Cloud Computing Benefits
• On-demand self service: consumers can provision
capabilities
• Broad network access: available on multiple
platforms/devices
• Resource pooling: resources (services) are pooled to
support multiple customers
• Rapid elasticity: capabilities can be provisioned and
released to meet demand
• Measured service: control and optimize resource use
Demystifying Cloud Computing
28. Cloud Computing Disadvantages
• Possible downtime: dependent on Internet
connection
• Security issues: must be comfortable with your data
on the Internet
• Cost: must look closely at pricing plans and details
• Inflexibility: be careful of proprietary applications or
formats
• Lack of support: lower cost might mean less support
or increased reliance on forums
