Cloud Computing and Cloud Computing Applications

By John Wallace
Meta: Cloud computing has become a revolution in the Internet era of today. To utilize to its utmost benefits, to establish understandings about cloud computing and its applications is necessary.
Cloud computing concept is now available ubiquitously, from IT forum discussions, on technology company reports to its appeance on the box of a newly purchased phone. It is said that there are still a lot of people misunderstanding the concept of cloud computing, and that cloud computing is just something like DropboxOneDrive or Google Drive, which is where you sync photos or files.

Essentially, this is just a small part of the problem; there is so much more about cloud computing. We would like to invite you to take a closer look at cloud computing as well as its applications and impacts on on the world nowadays and in the future prospect.

What is cloud computing?

Cloud computing is an IT model which allows access from different geographical areas and devices to shared pools of resources and services provisioned over the Internet.
According to IBM, cloud computing is the provision of computing resources to the user according to the purpose of the use of the Internet. That resource can be anything related to computing, such as software, hardware, network infrastructure, to servers and large server networks.
Explained in the simplest way, cloud computing is a paradigm for storing and accessing data and programs via the Internet to replace the use of hard drive.

Cloud computing features and advantages

Cloud computing aims at allowing users to make use of its benefits from all of its technologiews. Cloud computing will assist users in their core business instead of being impeded by IT difficulties.
The technology that enables Cloud computing is virtualization. Software for virtualization divide computing device into one or more virtual devices for using and managing computing task performance.

Since cloud computing is based on operating system-level virtualization which brings scalablility for system, idle computing resources can be distributed and exploited more efficiently. Virtulization creates agility that is required to make IT operations more rapid and reduce cost by increasing infrastructure employment.

What Cloud computing should not be messed up with?

Cloud computing should not be misunderstood with something like a dedicated network attached storage hardware or servers at a certain location or in different places.

So in order to deploy an application (for example, a website), traditionally you have to buy / rent one or more servers; then place them in data centers. With cloud computing, it now allows you to reduce the buying / hiring process. You just need to state your requirements, the system will automatically pick up the idle resources to meet your requirements. Therefore, there are some basic benefits of cloud computing:

Cost savings

Back then many years ago, the costs of off-site service for providing hardware location and purchasing hardware were a challenge for people. Nowadays, with cloud computing’s advent, it has changed this fact. Cloud computing platforms provide various consumption plans for users to match any user’s needs. The use of services is charged based on the resources wanted. Only consumption on storage is priced and it is much more affordable compared to acquiring all hardware, software and physical space for setting up data center and other incurred costs.

Automated growth and scalablity

Cloud resources based on virtualization as its core are configured for specific requirements but not a physical piece of hardware. This means that it is very easy to launch more of any specific resource needed by the company. When the user goes through growing period with a lot more data, the cloud can easily increase the amount of resources available without intense installation or configuration.  This is also true in reverse. If a company needs to reduce cost, then turning off resources or using less of a resource does not require much effort.

Cloud computing is based on virtualization and its resources are configured to meet specific requirements of users. It does not need to adjust greatly on the hardware but it launches based on the needs of company automatically.

Scaling is also an easy piece with Cloud computing service. Cloud provider can scale resources from small amount to large amount with no further configuration or changes in hardware.

Applications of cloud computing

+ Using Dynamic Computing Resources: Resources are allocated to the business exactly what the business wants right away by mobilizing available free resources on the Internet.
+ Reducing costs: Enterprises will be able to cut costs to purchase, install and maintain resources. Instead they just need to determine their needs and then ask cloud service providers to proceed.
+ Reducing complexity in the structure of an enterprise: The outsourcing of the establishment and operation of the IT system will allow the enterprise to focus resources on company’s specializations hence make the business structure less complex.
+ Increasing the use of computing resources: Some of the main questions of resource investment (eg, server) is how long it will run out of depreciation, whether the investment is profitable, whether the technology will be out of date or not. When using cloud resources, you no longer have to worry about this.

The big names in cloud computing

Cloud computing has only appeared for several yeasrso far; however, cloud computing today has a big number of applications. There may be many applications, software of high tech devices (smart phones, tablets, laptops) you are using with programs that apply cloud computin. The applications of cloud computing that we most commonly encounter today are:

+ Apple Icloud: Iphone or iPad are two types of high-tech equipment that we usually use today. In these types of devices, Apple usually provides you with an account called iCloud. This account allows you to store all personal data for use on the device. Icloud is one of the products that comes out of the cloud platform we use most often.
+ Google Drive: Google Drive is the storage space that Google provides for its user accounts. The storage space we use on Google Drive for daily data storage is also one of the applications of the cloud platform.

In addition to these two common examples, cloud computing today is widely used for the development of information technology.

How cloud computing comes in handy?           

Imagine you are CEO of a big company. It is your responsibility to ensure that all company employees have the necessary hardware and software for their work. Buying a computer system is not enough, you also have to buy more software and software licenses legally. Whenever there is a new employee, you also have to buy new software or transfer the current software license to another user. All of these are a hassle, time-consuming and costly.

And that's when you need cloud computing. Instead of installing one set of software for each computer, you just need to install one application / program for that computer. This application / program will allow your employees to log into the system on the web platform, which contains all the programs they need for their work. A remote server operating system owned by another company can help your employees run everything from e-mail to word processing to sophisticated data analysis programs.

In the cloud computing system, workloads are significantly altered. Computers at your business no longer have to do all the hard work like running applications, heavy programs. Instead, the computer network that makes up the cloud takes care of processing them, saving you a lot of hardware and software costs. The only thing that a user's computer needs to be able to run software is the interface to be able to use the cloud computing system, which can simply be a Web browser; and the cloud network will take care of the rest.

Most of us are already using cloud computing but not everyone understands it. Web-based e-mail services such as Hotmail, Yahoo! Gmail and the similar types are the most popular cloud computing applications. Instead of running an e-mail program on your computer, you log into an e-mail account through the internet remotely. The software and hosting for your account does not exist on your computer - it's on the cloud computing service.

Limitations of cloud computing

Although there are many advantages, Cloud computing also has certain disadvantages such as difficult to manage, security, not able to handle all data types. Over the years, many storage service providers have often warned customers about the types of data that will be removed in the future to save storage resources.

The advent of Cloud computing has brought a breakthrough in technology industry and life. Cloud computing has become so prevailing as its applications to economy and society are remarkably paramount important.  It has changed the way we process, use, access, store data.
