Recommended: Benefits of Using Virtualized Data Centers
Major power utilities today operate multiple redundant data centers with hundreds to thousands of utility grade computers to satisfy the computational needs of monitoring and control applications.
Some utilities have migrated their customer applications to hosting service providers, but the use of virtualization and cloud computing has found little room.
In contrast, the banking industry, which has been traditionally risk averse, is embracing cloud technology in an effort to meet customer demands quickly.
The authors wonder why the electric power industry is avoiding the use of cloud technology. Is it because it does not offer any significant benefit compared to dedicated computing infrastructures, or because with today's cloud technology the risks by far outweigh the benefits?
Could the risk be mitigated by choosing the right cloud deployment model, or could some of the risks be mitigated without explicit support of the cloud infrastructures?
What it will the cost in using cloud in the electric power industry?

VMs.
As conclusion, these potential solutions that can address individual security concerns, either in the form of cloud assurance or implemented at the application layer, there are no ready-made solutions.
Further research is needed to understand whether the individual solutions can be composed to provide necessary security properties at an adequate level.
We can improve the work that I already developed - Hadoop MR to tolerate arbitrary faults - and run it over a SDN.
This allows Hadoop run in a local and wide clusters, whilst OpenFlow adjust the network topology required by the application, and still tolerate arbitrary faults.
This network topology can form a cloud composed by several electrical substations. The Hadoop MR run in the clound and process the data sent by thousands of electric appliances.
DFS promises that its system can be extended by adding more nodes to accommodate data’s growing. Also it can remove those not frequently used data from overloaded nodes to those light nodes to reduce network traffic. Scalability is the capability of a system, network, or process to handle a growing amount of work, or its potential to be enlarged in order to accommodate that growth.

From businesses changing from water cooled equipment to air cooled equipment, to local governments using cloud computing within their regions. Due to the increase of water usage in water systems there needs to be a way to manage water supplies. “Energy use—such as use for cooling down power plants during hot summers—accounts for forty nine percent of U.S. water demand.” (Marshall, 1). I agree that businesses should use air cooling equipment, which could lower the reliability of water. The demand of water from power plants and other industries is increasing every year. The estimated increase is forty percent by 2030 if it isn’t changed. The cloud computing system is a great way to manage and store data electronically. The system helps city officials learn and figure out ways to save millions of gallons of water. The use of natural resources is another way to lower the scarcity of water. Natural resources will keep runoff and flooding
The healthcare industry has access to a patient’s personal health information, in electronic and paper form, and is responsible for protecting this information. The Health Insurance Portability and Accountability Act (HIPAA) establish requirements for the healthcare industry. The establishment and implementation of an effective information security plan is critical to meet these requirements and ensure this protection. There are however challenges and risks that must be addressed. Cloud computing can be defined as the use of computer resources without the expense of owing the hardware and software. Cloud computing is becoming more and more popular in major corporations as a way to gain use of specific programs, applications and even hardware by way of the Internet.
Even though cloud computing is still an emerging technology there are many benefits to our organization by adopting this technology. For instance, the reduction of operational cost, the ability to access data from any network and device, and the ability to upgrade and downgrade with ease whenever needed. Looking at the statistical data from companies that have adopted this technology, I think Partners in Heath should adopt Cloud computing. It think it is the perfect technology to solve our financial problems, as well as adding several benefits mentioned earlier.
Luke has been placed on a project to build an adult entertainment store on a piece of land that is located near his brother’s (Owen) home. It is certain that once the plans for the adult establishment are made public, property values in Owen’s neighborhood will “decrease significantly”. Luke is also aware of the fact that Owen is considering to sell his house. The house can be sold now for an “okay” price, however Owen thinks he may be able to get a better offer once the real estate market recovers.
In this paper, the authors define ground truth communities by selecting networks where the nodes define their relationship with the groups. After determining the ground truth communities, a comparison is performed between the network communities and the ground truth communities to find out difference of result in 13 chosen structural definitions of network communities. These 13 structural definitions gets partitioned into four classes and tested on the basis of three parameters: sensitivity, reliability and performance to determine the ground truth. Besides this, author also tries to find the network communities in case of a single node. To achieve the task author applies spectral clustering along with heuristic parameter-free algorithm to detect the communities of the node. The advantage of this algorithm is that it is extremely scalable and can be applied to networks with millions of nodes. We have studied clustering in our lecture; here the clusters might overlap as a node can have relationships with many communities, it is not confined to only one community, it means that the nodes are not exclusive. Also, these nodes in the network form densely linked clusters.
...Implementation of cloud systems can be implemented in stages with costs that coincide with usage. The ROI outweighs the issues or problems that could occur. Cloud computing gives a competitive advantage of being able to keep up with changes in technology without having the cost involved. Amazons cloud computing allowed companies like Ericsson to remain competitive and thrive.
There was a time when acronyms did not dominate everything known to identify television stations, radio stations or record labels. The American Broadcasting Company, (ABC), has been in existence since 1926, originally being founded by RCA, Radio Corporation of American and NBC, the National Broadcasting Company. By the year of 1948, ABC began to focus on television. This adaptation into full focus in the world of television was a struggle for ABC, yet the rest is history. ABC has launched a thousand ships in regards to great television programming and innovative marketing ideas.
The fourth characteristic of cloud computing is broad network access. The applications that are available through cloud services are accessible through a variety of devices and locations, allowing users to access applications through various types of storage not limited to the local hard drive. Furthermore, with cloud computing, users can access applicat...
Cloud computing facilitates sharing of computing and storage resources with the aim of reducing computing expenses in organizations. Moreover, cloud computing facilitates information sharing among individuals within a cloud. Despite being advantageous, data stored in a cloud is usually prone to hacking and other security issues. This paper addresses the various mitigation measures that organizations are using to ensure that data stored in the cloud is secure.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
For example services such as, Google Docs, Flickr, YouTube or Yahoo Mail, actually already using cloud computing. These allow you to store t...

Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
