What is cloud computing?

CLOUD COMPUTING AS EMERGING TECHNOLOGIES

cloud computing is used for storage and access data which needs at any time. the fundamental change it brings in how we view and think about computing. To better understand the massive revolution cloud computing will bring and is bringing to the field of computing, let's first go back in time and view a similar revolution with electricity.

Before the height of the industrial revolution, electricity had to be generated in house, this had many downsides: every worker lost to generating electricity was one less to make the factory more productive and scalability was a major issue, at times when production of the factory went up, there wouldn't be enough generated electricity, causing power outages and a loss of production. Thus, often times more electricity that needed was generated which was quite costly.

Then in the 1880s, Thomas Edison, founded the Edison Illuminating Company, turning electricity into a utility. In other words, something that could be switched on and off whenever desired, delivering the exact amount of power needed at a cost per unit, in the case of electricity, watts. Electricity as utility allowed for mass productivity increases and sparked further exponential growth in the industrial revolution, referred to as the second industrial revolution,

This because electricity as utility lowered the barrier to starting and maintaining a business, thus leading to more innovation. Coming back to present day, this analogy has strong correlations to transformations seen in computing

It is divided into three parts 

1. Iaas (infrastructure as a service)

2. Paas (Platform as a service)

3. Saas (Software as a service)

We are building infrastructure that used by others companies or users and they pay per use.

The platform which is used by other companies and customers to use.

The software which is used by other companies and users.
