Cloud computing is attaining a lot of awareness now days, both in print and in users, from individuals in the U.S. government. Nevertheless, it is not always clear defined however Cloud computing is a subscription-based service where you can obtain the network storage space and computing resources. The other way to imagine of cloud computing is to believe your understanding about email. Email application like Yahoo, Gmail, Hotmail, and so on, take care of all the hardware and software essentials to sustain your personal email account. When you want to access your email, you open your web browser, go to the email application, logged in and access your account. The most imperative part of the cloud computing is the access with internet. Emails are not be stored on your physical computer you access it with a support of an internet connection and you can use it anywhere in the world. For instance if you are on a trip, at work, or down the street to get coffee, you can check your e-mail as long as you can access the internet. The format of email address is different from the software installed on computer. The concept of email is same as cloud computing, anyone can use the cloud anywhere in the world while assessing through internet connection (Ojala & Tyrväinen, 2011).
Use of Cloud Computing:
The cloud makes it achievable for you to use your information from anywhere at any time. While a conventional computers entails you to be in the same location as your data storage device. Cloud eradicates the need of your physical presence at the location as your data is stored in the hardware. Cloud computing suppliers can possess the hardware and software availability to run home or business applications (Scale, 2009).
This is particularly constructive for businesses purposes; on the other hand homes users can not pay for the similar quantity of hardware storage space as a big organization do. Small companies can store their information in the cloud computing hardware and eliminates the huge cost of memory storage devices. In addition to that, it also requires buying storage spaces for the enterprise usage; you can also cut down the storage subscription as per your needs like when the business grows you can buy more space (Dhar, 2012).
The devices which can be a connectable to cloud are desktop, laptop, tablet, or phone. This can also help your business operate more smoothly because anyone who can connect to the internet and cloud computing can work on documents, and also access software data storage. Imagine picking up your smart phone and download a pdf document for review instead of having to stop by the office to print or upload it to your laptop. This is the freedom that the cloud can provide to you or your organization (Scale, 2009).
Types of clouds:
There are many different types of clouds that you can apply depending on your needs. As a home user or small business owner, you are likely to use public cloud services.
There are numerous kinds of cloud computing devices which you can use according to your need.
1. Public cloud – A public cloud can be accessed by any individual with an internet connection and access to the cloud computing space.
2. Cloud Private – A private cloud is established for a particular group or organization, and limited access to the group only.
3. Community Cloud – A community cloud is shared between two or more organizations require the same cloud.
4. Hybrid Cloud – A hybrid cloud is essentially a combination of at least two clouds, where the cloud consists of a mixture of public, private or community (Rader, 2012).
The information is located in the cloud is often considered valuable for individuals with malicious intent. A lot of personal information and data security potentials that people store on their computers, and this information will be transmit to the cloud. This makes it important for you to understand cloud provider security measures that you have established, and it is equally important to take preventive measures to protect personal data your data (Low & Wu, 2011).
The first thing you have to consider the security of your cloud service provider is in place. These vary from supplier to supplier, and between different types of clouds. They will have a backup of my data? They have a firewall set up? If you have a community cloud, what are the barriers in place to keep your information separate from other companies? Many cloud computing services providers have the standard terms and conditions can answer these questions, but consumers are likely to have less space to discuss in their cloud contracts. Small business users can be more than a few to discuss the terms of their contract with the supplier and will be able to ask questions during that period (Dhar, 2012).
No matter you are careful with your personal data, by subscribing to the cloud, you give up some control from an external source. The distance between you and your physical location of data is creating a barrier. It can also create more space for third parties to access your information. However, to exploit the benefits of cloud computing, you’ll have to try and provide direct control over your data. On the side, remember that most of the service providers cloud computing have a lot of information on how to keep your data secure. A service provider has the ability to have more resources and expertise than the average consumer to ensure their computers and networks (Berman, Townes, Marshall & Srivathsa, 2012).
To summarize, the cloud provides many options for everyday computer users as well as small and large businesses. It opens up the world of computers for a wider range of use and increases the ease of use by allowing access through any internet connection. However, with this increased ease also disadvantages. You have little control over who has access to your information and little or no knowledge of where it is stored. You must also be aware of the security risks of data stored on the cloud. The cloud is a big target for malicious individuals and may have disadvantages because it can be accessed through a secured internet connection.
