Cloud computing is not using your laptop in an airplane at 50,000 feet. Cloud is the metaphor of Internet. Cloud computing delivers computing services to users via a Network. It relieves users from managing or even knowing the infrastructure. Sometimes, Cloud Computing can be linked to utility computing, computing on demand, etc.

When it comes to Cloud Computing, three S’s come to one’s mind – Security, Speed, and Standard. Security make our mind at ease. After all someone else is managing our systems and data. Are they doing a good job? Is our privacy at risk? Speed makes everything enjoyable. Delivering computation over the Network, which could be Internet or private network, adds additional latency. Poor performance will turn users off. Standard insures user’s ability to avoid vendor lock in.

What does Cloud Computing mean to business and government? What is the economy impact to us?

It relieves business and government from operating private data centers on their own. As a result, the capital expenditure is reduced. Ongoing energy consumption is contained. As private data centers are often engineered for peak activities, the shared multitenacy Cloud Computing reduced unused capacity and resources.
