Cloud Computing
Answer
the following questions.
1. How
can cloud computing be simply defined?
A: - Though there is no official definition and straightforward way to explain what exactly cloud computing is, it can be expressed in general as follows:
Cloud computing is a type of computing environment where business owners outsource their computing needs including application software services to a third party and when they need to use the computing power or if the employees need to use application resources such as data base or emails, they access them via the internet.
2. What are the advantages of using cloud computing?
A: - We can clearly comprehend the advantage of cloud computing with examples: imagine that you have a small business, where you need a few small servers for database, emails, applications etc. Servers need high computing power and are very expensive. If you depend on cloud computing, you need not to purchase servers, and thus eliminate the need for an operation and maintenance team. The main advantage of using cloud computing facility is that customers do not have to pay for infrastructure installation and maintenance cost. Hence, it is cost effective as doesn't require huge number of servers, doesn't require software updates, installation, email servers, anti-viruses, backups, web servers and both physical and logical security of our data. So, cloud computing can help us focus better on our core business competencies.
3. How do the three kinds of cloud environments available differ from one another?
A: - A cloud environment can be broadly categorized into three types- public cloud, private cloud and hybrid cloud. While these three kinds differ from one another.
-->Public Cloud: - This is the most popular type of cloud system and is considered a mainstream one by cloud computing experts. In this type, a third party data centre provides both disk space and computing power for all the application software. Amazon Web and Google Apps are two of the most popular public cloud computing service providers.
-->Private Cloud: - Unlike public cloud, in this type you need to set up your own data centre and also bear all the installation and maintenance expenses. Hence it is more expensive than public cloud. While, it provides more security and privacy and you will have complete control of all your data which doesn't provide public cloud.
-->Hybrid Cloud: - This is a composition of at least one private cloud and one public cloud. A hybrid cloud is typically offered in one of two ways- a vendor has a private cloud and forms a partnership with a public cloud provider, or a public cloud provider forms a partnership with a vendor who provides private cloud platforms.

A hybrid cloud is typically offered in one of two ways- a vendor has a private cloud and forms a partnership with a public cloud provider, or a public cloud provider forms a partnership with a vendor who provides private cloud platforms.
4. What are the kinds of services offered by cloud service providers?
A: - A cloud service provider offers mainly three kinds of services.
-->Infrastructure as a service: -
The service provider bears all the costs of servers, networking equipment, storage and back-ups. The user just has to pay for the computing service. The users build their own application software. Amazon EC2 is a good example of this type of service.
-->Platform as a service:-
The service provider only provides the platform or a number of solutions for the users. It helps users save on investment on hardware and software. Google Gc engine and Force.com provide this type of service.
-->Software as a service:-
The service provider will give users the service of using their software, especially any type of applications software. Examples are Google, Salesforce.com and Net Suite.
5. What
are the main problems with cloud computing technology as it is today?
A: - There are two major problems with cloud computing. They are: technical developments and security and privacy.
In an era of outsourcing, all important data resides in a third party premises; there is, therefore, always a concern (or doubt) about the trustworthiness of the cloud service providers. Any security and privacy violation can be fatal. As a result, many business owners are still to be convinced about security and privacy in cloud computing systems. Data related to banking and government is particularly sensitive, confidential. Imagine what would happen if government documents were leaked or if information relating to credit cards fell into the hands of cyber criminals. Then it would be very problematic.
