4. Characteristics On demand service Use it as you needed
2. Network Access
Uses internet as a medium
3. Share resources
Resources are pooled together – Used by multiple clients

5. Cloud Computing Overview

6. Cloud Computing Overview
Power generator – When things work, it is great, when it doesn’t nothing get done
1900 Chicago – Edison power company developed a turbine power station – generate and distribute large scale power to business : Cheaper, more reliable and cleaner compare to any factory based generator.

7. Cloud Computing Overview
By 1920 most of the business switched to Edison, in house power generator no longer make sense since virtually unlimited power is granted.
1920 – Most businesses have made a switch. Business now access power simply by plug into the wall. In house power generator no longer make sense. Today, we take virtually unlimited power for granted. We can’t imagine it any other ways

8. IT Revolution IT has a similar revolution today.
Business No longer has to buy build and manager costly computer facilities on site
- More secure, more reliable and more scalable

9. Competitive Advantage
High Speed & Low Cost
24/7 secure access on more business apps
Traditional data facilities are struggling to keep up

10. Advantages Universal Access:
Cloud computing services are platform independent; they are accessible across all devices with internet connection. This increases mobility and ensures that you can access all your information from any place. By this, cloud computing also increase productivity as it allows staff to collaborate on projects.
More Storage Capacity:
Cloud computing offers an unlimited storage as long as you can afford it. You don't have to worry about running out of storage and having to buy SSD hard disks for backups.

11. Advantages Cost Effective:
As an on demand service, cloud computing is cheap. You only pay for what you use, and you don't incur the initial capital of acquiring the infrastructure. You don't also incur other costs such as maintenance, security, and storage costs. Some providers may offer cloud computing for free to their clients.

12. Advantages Easy and Quick Set-Up:
Unlike On-Premise infrastructure, when using cloud, you don't need to install anything or worry about the underlying hardware. All you need is to connect to a network/Internet, register with a cloud provider and adjust some simple configurations and that's it.
Automatic Updates:
Cloud providers are responsible for their underlying infrastructure. You will not worry about acquiring an update, a new software, their licenses or upgrading some hardware. With cloud computing, all this solely done by the provider. Maybe you only need to download a client software update. 

13. Risks
Security Risks
As with all other technologies, cloud computing is susceptible to security vulnerabilities. Cloud providers's servers can be attacked given the fact that millions of people are accessing them hourly. Since cloud uses the Internet, Internet related risks such as malware, man in the middle attacks and eavesdropping can be experienced.
Privacy Issues
The CIA triad - confidentiality, integrity, and availability of information can be breached when using cloud computing. Your data can be accessed by unauthorized entities or even modified.

14. Risks
Loss of Control
Using some services of cloud computing means that you lose control over some entities. The entities dictate on how they'll be used since cloud uses the on-demand service model. And at times if the servers are down, you will have no option but to wait.
Cloud Provider Reliability
Since you don't have control over the cloud computing entities, you have to rely fully on the cloud provider. If anything happens to your cloud provider, you will also be affected.

15. Risks
Internet Reliance: If you don't have access to the Internet, well, you also lose access to the cloud. And yes there are places where Long Term Evolution and even the 3rd generation networks are not available.

16. Delivery models of Cloud Computing
1. SAAS – Software as a service
2. PAAS – Platform as a service
3. IAAS – Infrastructure as a service

17. Common use of cloud

18. SAAS – Software as a service
On-Demand Service
Pay per use of application software to users
Independent platform
Don’t need to install the software on your PC.
Runs a single instance of the software
Available for multiple end users.
Accessible via a web browser or lightweight client applications
Computing resources managed by vendor

19. Who uses SAAS?
End consumer (End user)

20. SAAS PROS/CONS Pros Cons Universally accessible from any platform
No need to commute, you can work from anywhere
Excellent for collaborative working
Vendor provides modest software tools
Allows for multi-tenancy
Cons
Portability & Browser issues
Internet performance may dictate overall performance
Compliance restrictions

21. PAAS – Platform as a service
A platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure
This model allows you to manager data & the application resources
Open PaaS
Standalone PaaS
Addon PaaS
Application delivery PaaS
: All other resources are managed by the vendor

22. Who uses PAAS?
Developer

23. PAAS PROS/CONS Pros Cons Cost effective rapid development (scalable).
Faster market for developers.
Easy deployment of web applications.
Private or public deployment is possible.
Cons
Developers are limited to the providers' languages and tools.
Migration issues – such as the risk of vendor lock-in.

24. IAAS – Infrastructure as a service
Offers the computing architecture and infrastructure
Offers all computing resources but in a virtual environment.
Multiple user can access them.
Most vendors are responsible for managing four resources:
Virtualization
Servers
Networking
Data Storage.
If you will use this service, you will be responsible for handling other resources such as applications, data, runtime, and middleware.

25. Who uses IAAS?
Mainly for System Administrator

26. IAAS PROS/CONS Pros Cons The Cloud provides the infrastructure.
Enhanced scalability – dynamic workloads are supported.
IaaS is flexible.
Cons
Security issues.
Network and service delays.
