The document discusses cloud computing, including that it allows multiple users to access data through a single server without separate licenses. It describes cloud infrastructure models like full virtualization and para-virtualization. The pros of cloud computing are applications can be accessed without installation, unlimited data storage, and access from anywhere, while cons include internet outages, site access issues, and lack of secrecy. Cloud service models like SaaS, PaaS, and IaaS are also outlined.

1. Computing
Cloud

2. • Large group of remote servers
• Provide high storage space
• Multiple user can access data through single server
without purchasing licenses for different apps
• New IT focus

4. Cloud Infrastructure
Full
virtualization
Para
virtualization
• Installation actually in servers
but shown in clients
• For running unique apps
• One way to access cloud
• Multiple OS on one device at
same time
• Better scaling; requires less
processor utilization
• Used for:
a) disaster recovery
b) capacity management

5. Components :
Clients
Server
Distributed service

7. Pros:
1. Applications access without installing
2. Approx. unlimited data storage
3. Access data from anywhere
Cons:
1.Internet outage
2.Site access
3.No secrecy

10. PAAS ( Platform As A Service)
No need to install software
cloud providers deliver a computing platform.
Benefits: Application development, design &
testing.
Pros:
• Improved performance
• Lower cost
• Flexibility
Cons:
• Complexity
• Security
• Labor costs

11. Infrastructure As A Service
 IAAS offer computers – physical or virtual machines.
 Infrastructure as a Service is sometimes referred to
as Hardware as a Service.
 The service provider owns the equipment and is
responsible for housing, running and maintaining it.
 IAAS are costly.
 Used by corporates.
