When we hear the Cloud Computing word several things may come to our mind. So far we have several forms of distributed computing that we can mention Grid computing as an example. Cloud computing is the latest form of computing until now. Now, let’s take an example, imagine that there is no concept of technology as Cloud Computing. Moreover, in this situation, we have to store and recall our data from our personal devices that we have already saved them there. Additionally, imagine that our device has been crashed. So we can not access our information at all. So, Cloud Computing is here to help us. Apart from storage, we can access various utilities that Cloud Computing provides. These utilities include:

• Online File storage
• Photo editing software
• Digital video software
• Twitter-related applications
• Creating image-album
• Web application for antivirus
• Word processing application
• Spreadsheets
• Presentation software
• Finding a way on the map
• E-commerce software
• Miscellaneous applications

Cloud characteristics

On-demand Capabilities

Cloud Computing users can simply provision resources without human interactions. In addition, they can simply log in to their dedicated dashboard and then add or remove their desired services.

Broad Network Access

Cloud Computing users should easily access the data and service whether by their personal computers, laptop, or their smartphone. Moreover, in terms of network accessibility, one thing that can be so highlighted from the views of customers and businesses would be mobility.

Resource Pooling

Cloud service providers in cloud computing should simply provide access to their users’ access to existing resources. Also, cloud providers should assign and reassign cloud resources depending on the user’s needs.

Rapid Elasticity

Since users access the provisioned resources and can scale them up or down, in cloud computing elasticity plays an important role. Sometimes users according to their needs can scale up or down the resourced. For example, if users need more resources cloud provider assigns more resources, and when they don’t need extra resources, other resources can serve other users.

Measured Service

Some cloud service providers give you the opportunity of monitoring the amount of resource usage. If you have or used Amazon cloud infrastructure it offers you several services but you only pay for something that you are using them. In plain English, it is called pay per Use.

Requires appropriate internet speed

All these services are launched in cyberspace, and to use them, you will need high-speed Internet to be able to take full advantage of it.

Security

The issue of security is an important and big issue, which has brought various opinions from experts in this field

Cost reduction and environmentally friendly

In cloud computing, usually, users use an average of 10 to 20% of the capacity of a personal computer. At peak times, computers are sometimes left unused for hours. Resource management and driving users to use cloud computing stabilizes energy consumption and saves because it consumes as much as needed and is paid for.

Consumer preferences

The most successful businesses are those that reflect and satisfy consumer desires. The consumer seeks to run his business with a modern approach and as he pleases. Moreover, some experts believe that the use of cloud computing spreads information on the Internet, and this causes others to infiltrate and leak information. On the other hand, some researchers believe that it is highly secure, and cloud computing providers meet this expectation to a large extent. In addition, It is important to note that storing data locally over the cloud gives users less control as they delegate control of their files and confidential information to another person or company.

Application on social media

Today, social networking among entrepreneurs has become an important part of planning for the future. Companies these days use social networking sites to increase their productivity as well as business and marketing.
