 Cloud computing is the use
of computing resources (hardware and software)
that are delivered as a service over a network.
 The name comes from the use of a cloud-shaped
symbol as an representation for the complex
infrastructure it contains in system diagrams.
 Cloud computing entrusts remote services with a
user's data, software and computation

4. TYPES OF CLOUD COMPUTING
 Infrastructure as a service (IaaS)
 Platform as a service (PaaS)
 Software as a service (SaaS)
 Network as a service (NaaS)
 Storage as a service (STaaS)
 Security as a service (SECaaS)
 Data as a service (DaaS)
 Desktop as a service (DaaS )
 Database as a service (DBaaS)
 Test environment as a service (TEaaS)
 API as a service (APIaaS)

5. ADVANTAGES OF CLOUD COMPUTING
 Improves the speed of your work
 Cost effective
 Device and location independence
 Reliable
 Scalability and elasticity
 Security
 Easy mantainance

6. TYPES OF CLOUDS
 Public cloud
 Community cloud
 Hybrid cloud
 Private cloud

7. COMPARISON BETWEEN PRIVATE AND PUBLIC
CLOUDS
Public cloud Private cloud
Initial cost Typically zero Typically high
Running cost Predictiable Unpredictable
Customization Impossible Possible
No (Host has access
Privacy Yes
to the data)
Single sign-on Impossible Possible
Easy while within
Scaling up Laborious but no limits
defined limits

8. DISADVANTAGES
 Privacy ( in public clouds)
 Legal problems
 Sustainability
 Abuse
