CLOUD COMPUTING

I decided to break down the major aspects of cloud computing into 6 major categories since there's six of us in the group. 
The contents are as follows: 

- Intro/History (good for an introduction)
- Characteristics/Advantages
- Layers & Architecture (i.e. how it works)
- Types of Clouding
- Companies adopting the technology (i.e. MS, Intel, IBM, etc also with a focus on Canada)
- Implications for the Future/Conclusion

What is Cloud Computing?
According to wikipedia, cloud computing is a model for IT services based on the Internet that typically involves 
the provision of dynamically scalable  and often virtualized resources as a service over the Internet. 

What does that mean? Well, in a cloud computing system, there's a significant workload shift. Local  computers no longer 
have to do all the heavy lifting when it comes to  running applications. The network of computers that make up the cloud
handles them instead. Hardware and software demands on the user's side  decrease. The only thing the user's computer needs
to be able to run is  the cloud computing system's interface software, which  can be as simple as a Web browser, and the
cloud's network takes care of  the rest.

Characteristics of Cloud  Computing

1) Agility - improves with users' ability to  rapidly and inexpensively re-provision  technological infrastructure resources
2) Cost - is  claimed to be greatly reduced and capital expenditure is converted to operational  expenditure.
3) Device - enable  users to access systems using a web browser regardless of their  location or what device they are using.
4) Multi-tenancy - enables  sharing of resources and costs across a large pool of users.
5) Reliability - improves  through the use of multiple redundant sites, which makes cloud  computing suitable 
for business continuity and disaster recovery.
6) Scalability - via  dynamic ("on-demand") provisioning  of resources on a fine-grained, self-service basis near real-time.
7) Security - could  improve due to centralization of data[38],  increased security-focused resources.
8) Sustainability - comes  about through improved resource utilization, more efficient  systems, and carbon neutrality.
9) Maintenenace - cloud  computing applications are easier to maintain, since they don't  have to be installed 
on each user's computer.
