In this section we mention the advantages of cloud computing.
Advantages of Cloud Computing
Reduced costs: Instead of buying multiple servers and their own components, licensing operating systems and applications, installing all these and following up on updates and troubleshooting, the Cloud works centrally, and updates its components centrally without disrupting any Cloud. On the other hand, the calculation of the cost of using the Cloud depends on the amount of resource consumption, such as how much data processing, memory capacity, storage and data transfer is calculated by hour or month. In general, the larger the company and the larger the number of employees, the greater the resulting savings.
Larger storage capacity-[Advantages of Cloud Computing]: You rarely find a server using even its maximum capacity, either in terms of processing or storage, so when you combine these unused energies together, on a large scale, you find a great abundance that can be exploited, the most prominent of which are giant storage capacities that can be accessed from more than one source. Studies and statistics indicate that businesses need to double their computing resources every year. At the top of the list comes the need for storage, as the volume of customer databases and users of any company increases.
Flexibility-[Advantages of Cloud Computing]: With one command, a replica of an existing server running can be made or restored and run when the original server stops for any reason. In the same way, server resources can be increased with a sudden increase in the number of users, and server resources used by a limited number of users can be reduced to reduce their cost. Companies that need to experiment with various hardware and applications to find out which solution will suit their needs can do so on the Cloud in less time and at less cost than buying servers and testing applications.
Easy access-[Advantages of Cloud Computing]: Whether you’re browsing the Internet from a mobile, tablet or a small home computer, or a TV that supports Internet browsing, you can access data stored in the Cloud whether you’re at home, on a plane, on a ship, or on a car. The Cloud makes you closer to your data and information, thus helping you to increase productivity and profitability.
Easier in management-[Advantages of Cloud Computing]: Instead of wasting time managing each component of a company’s server matrix, distributed over multiple locations, cities and countries, the Cloud provides a centralized control interface that controls each component of the Cloud, without having to travel or connect a screen to a server or otherwise. This interface can be accessed over the Internet. This centralized management makes servers much easier, less time and less tired, and one specialist can implement them, instead of providing a team of engineers and technicians going on each server and watching. Activating application updates and operating systems on the Cloud is easier and easier, because of this centralization.
More time-[Advantages of Cloud Computing]: Because of all of the above, system administrators will have more time at their disposal, enabling them to think about future strategic planning for the company and the organization. This may have helped to reduce the technical staff, which in turn reduces costs and expenses and thus increases profitability and productivity.
Greater security-[Advantages of Cloud Computing]: Because data is centrally stored in the Cloud, it reduces the need to store data of critical importance to the enterprise on mobile computers, thereby reducing the potential losses that may occur due to the loss of less critical data by an employee. This centralization also allows for greater ability to monitor data access, and to identify, increase and reduce authority when needed.
Friendly environment-[Advantages of Cloud Computing]: Because a large number of servers are clustered in one location, they can be powered by a green card, such as solar panels or wind towers. The use of dedicated servers in their high rectangular form makes them operate less, and consume less power than the traditional large conventional server. At the moment, the United States and Europe are very concerned about the environment, encouraging individuals and companies to reduce energy and electricity use, and some expect them to start preferring companies that pursue policies that reduce energy use and carbon emissions.
Characteristics of Cloud Computing
There are many characteristics of Cloud computing, but there are five basic characteristics agreed by researchers. These are:
On-demand self-service: With on-demand self-service, consumer can control the available services in the Cloud, such as adding or cancelling services without needing to refer to the service providers, usually by interacting “Dashboard”.
Resource pooling: Different resources are collected in one physical location or in different physical locations according to conditions such as (security and consumer demand) to serve consumers depending on user demand. These resources can comprise storage, memory, processing, and network bandwidth. For legal reasons, users need the information about the location of datacenters but generally, the Cloud service users have no information about how and where service provider’s datacenters could maintain these resources.
Elasticity: This feature is one of the most important characteristics of Cloud computing. It gives Cloud computing a special advantage, it can quickly and flexibly provide resources, and in some cases automatically, also the ability to increase or decrease Cloud services on demand, without resorting to the service provider. In order to take advantage of the elasticity of a Cloud infrastructure, the applications should have the ability to scale up (adding more resources) and scale down (removing resources that are no longer required).
Broad Network Access: The consumer can access through standard mechanisms and devices such as mobile phones, computers and operating systems. So, it is a flexible service – where laptops, computers and tablets can be available to the user as much or as little as he wants at any time and through any type of communication device.
Measured service: Providers and consumers have the ability to control, measure and report Cloud computing resources by using metering capability. The main purpose of the measured services is to economize based on the measurement as well as to pay according to what is consumed from the resources. This pricing model provides flexibility in the computation of resources and helps to provide efficient use and flexibility in traffic.
