What is Cloud Computing?

What is Cloud Computing?

Cloud Computing can be known as “the cloud”, in basic terms this process deals in collect or acquiring your data and programs over the internet rather than your own hard drive.

Let us know the types of clouds now:

Public Cloud:Under this deployment mode, the services which are deployed are open for public use and generally public cloud services are free. Scientifically there may be no contrast between a public cloud and a private cloud, but the security points is very different, since the public cloud can be used by everyone and there is always a risk factor involved with the same.

Private Cloud: This cloud service is operated solely for a single organization; it can be done by the same organization or a third-party organization. Generally the prices are high when you are using your own cloud platform since the hardware would be updated periodically; security also has to be kept in mind since new threats come up every day.

Hybrid Cloud:
A hybrid cloud consist the functionalities of both private and public cloud.Lot of challenges are faced by cloud platform, let us discuss these factors one by one:

  1. Cloud is insecure

Whenever we discuss about cloud platform, there would be a lot of people saying, the data is more secure on their own infrastructure rather than say some AWS server with AWS security.
This is well said but the fact is that if the company would just focus on their private cloud’s security which generally is not the case. Generally if the company only looks after that, when will they focus on their own goals?
Let’s discuss about Cloud service Providers, like AWS, the largest of them all, don’t you think AWS’s sole purpose is to make your data the most secure? Yes, as that is what they are being paid for.

  1. There are more breaches in the cloud

Cyber-attacks in 2012-2013 were both targeted at private clouds and public clouds, but the private clouds were more susceptible to the attacks, because companies which use their own servers are not that fully equipped as compared to AWS or Azure or any other Cloud Provider for that matter.

  1. Single occupant systems are more secure than multi-tenant systems.

If you think reasonably, don’t you think that with multi-tenant systems you have an additional layer of security attached to it? Because your system will be logically isolated from the rest of the occupants or users on the system, which is not there if you are using single-occupant systems. However, in case a hacker wants to go through your system, he has to go through one additional layer of security.
