Cloud Computing {2}

by Jamal A
The article I read talks about how working in a cloud environment is becoming the modern fashion for IT professionals.  There are some advantages of cloud browsing such as flexibility, efficiency, cost reduction and environment friendliness.  According to the article, there are some differences between traditional servers and cloud servers. Traditional servers and cloud servers are two diverse methods of storing data. The best way to explain is that traditional servers provide physical accessibility where you can control or restrict the direct connections. On the other hand, cloud browsers is all about virtualization meaning the server and its components are located somewhere else and the only way to contact or access data is by the screen in front of you.  Because of cloud computing, employees will be able to use any device to access, transact and manage their work. Companies are concerned about the data security more than ever that is the reason they are adapting cloud computing, because it is the safest way to access data.  Supporting that cloud computing, however, has Encryption of sensitive data used by cloud based virtual machines. Even though, cloud servers are available 24/7 the data is only accessible according to company policies. read more...

Cloud Computing Qualities {3}

by Kaushal S
Good bye hard drives and welcome endless space of storage the “Cloud Computing”. It has become the next best thing in the cyber world. Before there was a need of backing things in case of a crash or other catastrophes but now all that has been put to rest, thanks to cloud computing. It is basically virtual servers available over the internet for sites such email providers, online vendors (amazon, ebay, etc) or could be there to provide us with information (Wikipedia, eHow, etc). This article may sound a very introductory in ways to a lot of people but this provides important insights about cloud computing. It works as SaaS (Software as a Service) which is extremely easy and affordable for users to use and almost no work for providers to maintain it. It also talks about how it also helps in utility computing, how it helps run web services, mash up platforms. Cloud computing also works great with monitoring services such as antivirus programs.
Cloud computing helps run many different platforms in its function such as Service commerce platforms. It allows users do business such as purchasing and making transactions between consumers and vendors. It allows internet integration for various things to come together and makes our cyber experience more enriched every time we visit the cyber world. read more...

IT Evolution {1}

by CyberChic
IT is moving to the upper stratosphere where clouds reside. Bernard Golden (2012), who is the CIO of a cloud management software company states that many small and medium companies are giving up in-house information centers to obtain cost advantages by switching to mega-data centers or cloud computing. Being in the vortex of this disruptive technology, Golden (2012) also says that “IT is moving from supporting business processes to being the business’s processes, and that traditional application designs and infrastructures are inadequate to support today’s needs,” which is a very interesting change.
With our storage technology, we have been capturing data for decades. All stored in databases of every kind. It keeps growing and growing. At some point, it becomes cost effective to have someone else, a cloud, hold data or databases for us.
Who came up with the terminology? Cloud gives you no idea where the data is being stored except out there somewhere. Maybe someday with quark technology, it may really be in the clouds but for now it refers to mega-data centers. One company that operates cloud computing is Switch. Their data center is called SuperNAP and it is located near Las Vegas, Nevada. It is roughly 400,000 square feet now with plans of expanding it to two million square feet. Wow, that’s big. read more...

Cloud security {5}

by Daniel M
The article that i read was about how companies and IT professionals feel about the security of cloud computing. Cloud computing allows for flexibility in access to a companies data and allows the employees to have access to the data at home without physically taking the data out of the companies building on a storage device. The problem is how secure the data is on the cloud and what information do you trust to another company to store and back up for you. The article says that 46% of companies trust cloud services with a moderate amount of data and only 13% of the companies trusted it with a heavy amount of data. 54% of the companies that were polled said that cloud computing security is a top priority. The companies had a list of things that they would not trust to a cloud service and 58% said that they would not trust their financial data to a cloud service. The next highest was 56% said that they would not put credit card information on the cloud either. The article also talks about how 72% of all cloud users do not have the tools to audit the cloud environment. read more...

Technology of Cloud Computing {2}

by Rizwan A
Technology is an amazing things, it has change through time from the way we have carried our date, from the floppy disc drive to now the USB flash drive. But now the USB drive seems to be considered out dated technology.

According to Shaikh, F.B ; Haider, S the newest form of caring around our data is not a physical devices it is now being store to the World Wide Web by using cloud computing, which in turns mean that anyone can access it anywhere at any time around the World. So for example, if a business man forgets his flash drive back in the office, he won’t have to worry about his presentation because he can retrieve the data from cloud computing. This is a big shift for the way we can understand technology and cloud computing has made it more convenient for the everyday working man or women. read more...

Cloud Computing: Self-Service IT Management {Comments Off on Cloud Computing: Self-Service IT Management}

by Arlyn R
In Morrison’s (2011) article, “Power Unplugged to the People; How Cloud Management Will Transform It”, analogies between everyday life and utilization of cloud computing are skillfully connected to demonstrate how Cloud services will shape the future of Information Technology management. Salesforce.com, a trailblazer in Software as a Service hosting, is referenced in this article to display how their Customer Relation Management software bolstered its success with its customizable, scalable, and cost-effective cloud computing application. Morrison attributes Apple Incorporated’s success to seamless configuration of their products. Apple’s vertical integration that assimilates the OS, hardware, and software to a standard has proven that “…limiting choice isn’t really all that limiting; rather, limitation is the key to operational efficiency” (Morrison, 2011, p. 16). Cloud service also uses a uniform model to simplify operation, which allows end users to easily adapt to the standardizations of cloud computing without compromising the firm’s business goals. Morrison compares cloud computing to self-service gas station as both gas pumps and cloud computing use standardized configuration. Self-service gas pumps eliminated unwarranted labor costs and cloud computing transfers decision support power from IT to end user increasing competitiveness and efficiency. read more...

A Professional Look at Cloud Computing Security {1}

by Jennifer R
 

The authors start the article with a brief overview of the advantages of cloud computing, mentioning flexibility and scalability among other things. They acknowledge that cloud computing has potential, but comes with significant disadvantages that need to be addressed. One of the main issues is security. They conducted a survey to determine how businesses and information technology professionals felt about aspects of cloud computing security and what their top concerns were. They covered a range of topics, from what organizations would not want to put on the cloud to concerns of both users and information technology professionals. As is common with information stored on a network, a majority of the concerns involved regulating user access and protecting information from unexpected loss or attacks. read more...

Cloud Computing and CPA Firms {4}

by Jasmine C
The article I read about was how cloud computing was being used by many CPA firms.  Even though cloud computing has been out for a while, recently it has been gaining popularity all over the world.  Cloud computing works by using the Internet and central servers to remotely store and access  information.  A company by the name of CCH, who develops the accounting software ProSystem Suite, is using cloud computing to house many of their products and many other accounting programs, like Quickbooks and Peachtree, can use the cloud.  The article discusses the many problems associated with servers.  To state just a few, I read that servers are only have a lifespan of 3-4 years,  they are complicated and expensive, they reside in data centers which increases the risk of losing important information if something were to happen to the data center, and for many accounting firms, a lot of server space is left unused during the months in which the firm is not that busy.  This us not beneficial to the firm because they are using their resources for a system that only benefits them when they are in their busy season.  By using cloud computing, firms can improve their backups, they can bring ideas to the market faster, they will be cost efficient because they will not be wasting money on staff, products, or unused server space.  Security for cloud computing is continuously advancing and this is good for CPA firms because they need great security for their sensitive data. read more...

Green Cloud computing {1}

by Bernard T
Cloud computing has seen a rise in popularity since its inception and is becoming a popular alternative to traditional computing. As cloud computing becomes more widely used the question of how these computing resources are maintained are starting to be on the minds of the people using them. The article I read discuss the issues that relate to balancing energy consumption between those who offer cloud computing services and those who use them. It focused mainly on three cloud services; storage as a service, processing as a service and software as a service for both private and public clouds. The article examines each of these services closely and gives the reader an insight into what it takes to run computing services in the cloud, particularly the energy consumption that occurs during to transport of the data. They approached this question as a “classical supply chain logistic problem, which considers the energy consumption or cost of processing, storing, and transporting physical items” but in place of physical items they use bits of data. Each particular service went through intensive and elaborate testing each with its own customized formula that measured energy consumption from the user, transport medium and the cloud. For example, they measured the energy consumption of a “storage as a service” from a cloud by users at the rate one download an hour for a set amount of time and saw that energy consumption of transport dominated total power consumption. There were many such tests which showed energy usage between the cloud and user computers which makes you realize that there are other mitigating factors that should be considered when it comes to measuring total energy consumption (not just from the servers and users).
We are living in a time of global warming, over consumption and pollution, it is more important now than ever to be “green”. I believe that knowing about what goes into using these new technologies, like energy consumption from both the cloud, the end users and everything in between is very important especially during these times we live. Before this article I never considered the energy consumption of data transport and I am glad I am now aware of it. The author’s of the article did this study because they wanted to know the contribution to total  power consumption when performing cloud computing. They came to the conclusion that transport of data was a significant portion of total power consumption for cloud services at medium to high usage traffic. Overall, they concluded that using cloud storage services are more energy efficient than storing locally on hard disks drives when files are occasionally accessed by a few users. Consequently, as the number of users who access the cloud increase so does the power consumption of transport to the point where energy savings is minimal, which means that even though the users might be using less power at their end, cloud computing as a whole is not always the greenest option because of the total energy needed to transport data from the cloud to its users. read more...

Changing The IT Playing Field {1}

by Anthony T
Interestingly enough construction companies are seeing and contributing to the change in the field of IT. Data centers being built today, according to Mortensen Construction executives, are at a much larger scale than they once were. One particular data center worth mentioning is the Switch which boasts 400,000 square ft. It’s size allows many different cloud providers to run their operations inside this enormous data center. Software development companies, such as Smith Electrical Vehicles, which process large amounts of data are becoming aware of the computer capacity of the new age data centers. Traditional IT infrastructures can no longer handle the needs of companies like Smith Electrical Vehicles which is why data centers like the Switch are becoming more and more popular. This trend of large scale data centers is directly related to the growing needs of enterprises in terms of computing.
A common topic both in this article and in this weeks lecture was database schema. The article mentions that companies have had to design their schema by means of schema redesign and sharding to enhance application performance. The concept of sharding really grabbed my attention. Turns out this concept refers to process in which you can break your database down into small pieces and then send it to multiple servers.
Having read this article I now understand one of the major trends that is happening in the field of Information Technology. As an IT undergrad I feel that articles like this one are very useful in helping students like myself understand that in order to be successful in this field we must also be aware of how the industry is shifting away from traditional corporate environments. read more...
