Cloud Computing simply define as variety of services that delivered over the internet. Most often benefit’s users of this technology are large companies, organizations, educational institutes and very limited number of ordinary internet users.
The National Institute of Standards and Technology (NIST) define the Cloud computing as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
There is no doubt this new technology- revolution in near future will change the course of dealing with Devices (e.g., laptops, Cellophanes, Desktops, PDAs and etc). Those devices will be just a transit station for accessing to the cloud computing server that contains your storage space, documents, and applications to deal with your data over the internet.
The Cloud Computing infrastructure depends on providing large storage space, data centers, and networks, its role to offering programs and applications as services for the users, and relies heavily on technology of Web 2.0.
1. Pros & Cons of Cloud Computing
Like anything else cloud computing has advantages and disadvantages which also has its limits. Below I will cover some of these points.
a. Pros
• Cost Saving: it reducing the purchase of equipment.
• Limitless computing and storage: There is no limit to the storage and processing on the cloud theoretically, but there are some obstacles in practice.
• Focus on core business instead of IT: Business owners need to focus on their core mission rather than trying to process and manage information technology.
• The provision of resources and a more dynamic: Users can provide the computing resources they need at any time and in a dynamic way.
• More effective: It does not matter whereabouts of your “machine” the most important is to operate it well and that service is available constantly.
• IT-friendly environment: the cloud computing and virtual environment in general will play very important role to be effective in the development of the "Green IT". These new techniques of the cloud computing will reduce the amount of energy emitted from the physical servers by hosting the applications on the virtual machine to perform the same tasks on physical server. In addition, it will reduce the amount of the energy that you need to cool or operate the data center content on those servers.
b. Cons
• Security: is very annoying word for cloud computing business .leaking out confidential information and data through the cloud computing system might cause huge loss and risks to the corporation. Therefore, security issues is one of major demerit of cloud computing.
• Requires continuous Internet access: if you lose your internet connection that means your OFF period is out of work.
• Lack of control: when the cloud goes down the IT managers will be helpless because there isn’t visible infrastructure.
2. Challenges impeding the cloud computing
Cloud computing puts many obstacles in the way of those who want to use;
• Can be trusted storage?
• If terrorists initiate cyber-attacks on some number of clouds computing what will happen to your business?
• Privacy still not clear term in cloud.
• Ownership of the data?
• How to guarantee that level of service is meeting the real business needs?
• Is it provides this service always? What about service level agreements?
• Network Connectivity?
• What about the Internet and connect to the network access servers and the various services on the cloud?
• Joint action and integration of services between the clouds.
• Is there a possibility to move from a vendor service to another without the need to change the text and the environment in which I work? Cannot prove or compliance review afterword.
3. Skills required for the change to the cloud
Cannot operate without a cloud computing technology; humans will need IT professionals to work more to provide basic business functions. Most companies will run into some technical elements of the cloud and others outside, which requires the cooperation and fruitful creative services for the management of difference between internal and external work. For example, some institutions will need to put some regulations on the Internet and combine some of the services and network engineers will also need to solve some problems, direction and management and to address various challenges. All of these elements work of IT will blend within the environment of the cloud.
Therefore, will be need for well-trained IT professionals in order to accommodate this kind of changes, also by learning new techniques of controlling infrastructure, observing the virtual machines, development platforms and the way in which application is published and made available to any provider of cloud.
