1. Cloud Computing
Cloud computing is an emerging
computing technology that uses the
Internet and central remote servers to
maintain data and Applications´

2. Benefit

3. Benefits
• Increase IT responsiveness and efficiency.
• Reduce capital expenditures and operational
overhead.
• Provide greater business flexibility through an
on-demand, pay-as-you-go model that scales
with your business.
• Get more choice in providers — use in-house
or third-party vendors.
• Free up IT resources for innovation

4. What is Cloud Computing
A style of computing where massively scalable
(and elastic) IT-related capabilities are provided
“as a service” to external customers using
Internet technologies.

5. DISA’s Components to Cloud
Computing
Platform-As-A-Service (PaaS)
Infrastructure-As-A-Service (IaaS)
Software-As-A-Service (SaaS)

6. Platform-As-A-Service (PaaS)
It is a software development and hosting
environment made up of development tools,
databases, middleware and infrastructure
software.

7. Infrastructure-As-A-Service (IaaS)
It enables your system administrators and
developers to self-provision the compute,
storage and network resources they need to
deploy and run applications and operating
systems

8. Software-As-A-Service (SaaS
It gives your users web access to applications
hosted on a service provider's infrastructure. A
wide range of applications can be
delivered through a SaaS model, such as
customer relationship management,
collaboration, email and enterprise resource
management.

9. Cloud Structures
• Private clouds, whether operated and hosted by your
enterprise IT department or by an external provider, are for
the exclusive use of your organization.
• Public clouds are open to any number of organizations and
individual users on a shared basis. Using a public cloud
minimizes your initial capital investment and combines
agility and efficiency with massive scalability.
• Hybrid clouds link private and public clouds, providing
access to extra resources when the private cloud hits
maximum utilization. Or, a hybrid cloud might split
computing by tier between private and public clouds. For
example, the database may reside in the private cloud
while the application server is located in the public cloud.
