Q.1 What is cloud computing?

ans:the practice of using a network of remote servers hosted on the Internet to

 store, manage, and process data, rather than a local server or a personal computer.

Q.2 who invented the cloud computing?

ans:Cloud computing is believed to have been invented by Joseph Carl Robnett Licklider in the 1960s.

 with his work on ARPANET to connect people and data from anywhere at any time.

Q.3 what are the types of cloud computing?

ans:(a)Public

 (b)private

 (c) hybrid

Public clouds are made available to the general public by a service provider who hosts the cloud infrastructure. 

Generally, public cloud providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet. 

With this model, customers have no visibility or control over where the infrastructure is located.

 It is important to note that all customers on public clouds share the same infrastructure pool with limited configuration,

 security protections and availability variances.

(b)Private

Private cloud is cloud infrastructure dedicated to a particular organization. Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control, which is often lacking in a public cloud environment.  It is not shared with other organizations, whether managed internally or by a third-party, and it can be hosted internally or externally.

(c)Hybrid

Hybrid Clouds are a composition of two or more clouds (private, community or public) that remain unique entities but are bound together offering the advantages of multiple deployment models. In a hybrid cloud, you can leverage third party cloud providers in either a full or partial manner; increasing the flexibility of computing. Augmenting a traditional private cloud with the resources of a public cloud can be used to manage any unexpected surges in workload.

Q.4 what are the advantage of cloud computing?

ans:

1)Achieve economies of scale – increase volume output or productivity with fewer people. Your cost per unit, project or product plummets.

2)Reduce spending on technology infrastructure. Maintain easy access to your information with minimal upfront spending. Pay as you go (weekly, quarterly or yearly), based on demand.

3)Globalize your workforce on the cheap. People worldwide can access the cloud, provided they have an Internet connection.

4)Streamline processes. Get more work done in less time with less people.

5)Reduce capital costs. There’s no need to spend big money on hardware, software or licensing fees.

6)Improve accessibility. You have access anytime, anywhere, making your life so much easier!

7)Monitor projects more effectively. Stay within budget and ahead of completion cycle times.

8)Less personnel training is needed. It takes fewer people to do more work on a cloud, with a minimal learning curve on hardware and software issues.

9)Minimize licensing new software. Stretch and grow without the need to buy expensive software licenses or programs.

10)Improve flexibility. You can change direction without serious “people” or “financial” issues at stake.
