Cloud computing is a service delivery model via internet which provides online computing and storage power to users. Being an internet based remote service; users can access the cloud services anytime, anywhere. Cloud computing allows and makes it easier to access technology-enabled services to the users who don’t have adequate technological know-how. These literatures are more focused on core cloud computing service model being deployed and deployment model followed by the cloud service providers. Additionally anticipated and achieved benefits, challenges and growing deployment trend are also analyzed.
This literature review surveyed existing literature available on the database using systematic approach. Each literature is taken from the CEO magazine, Australian computer society and UWS library catalogue and few literatures from Google scholar. For the timely updated information we limited our literature and taken only published journal article after 2005, because cloud computing is come into mainstream practice from that year. Briefly abstract and title of the papers was studied peer-reviewed journal articles are chosen.
Cloud computing model
All these literature categorize entire cloud computing in three major service models. * Software as a service, SaaS model
In this model, application and functional services are designed to be hosted online and delivered via typical web browser. Users don’t have to have a physical copy of the software installed on their machine, eg. Gmail docs, Gmail, Dropbox etc. * Platform as a service, PaaS model
Unlike the SaaS model, this model provides the software platform to its users instead of only standalone software. Different development tools for easier development and deployment are provided online. Users have application level access to the platform and they don’t have to worry about operating...

...Cloud Computing: A Taxonomy of Platform and Infrastructure-level Offerings David Hilley College of Computing Georgia Institute of Technology April 2009 Cloud Computing: A Taxonomy of Platform and Infrastructure-level Offerings David Hilley 1 Introduction Cloud computing is a buzzword and umbrella term applied to several nascent trends in the turbulent landscape of information technology. Computing in the “cloud” alludes to ubiquitous and inexhaustible on-demand IT resources accessible through the Internet. Practically every new Internet-based service from Gmail [1] to Amazon Web Services [2] to Microsoft Online Services [3] to even Facebook [4] have been labeled “cloud” offerings, either officially or externally. Although cloud computing has garnered significant interest, factors such as unclear terminology, non-existent product “paper launches”, and opportunistic marketing have led to a significant lack of clarity surrounding discussions of cloud computing technology and products. The need for clarity is well-recognized within the industry [5] and by industry observers [6]. Perhaps more importantly, due to the relative infancy of the industry, currently-available product offerings are not standardized. Neither providers nor potential consumers really know what a “good” cloud computing product offering should look like and what classes of products are appropriate. Consequently, products are not easily comparable. The scope of various product offerings differ and......

...1.With Google Glasses, the technology disappears from in front of you and you get data and applications in the context of what you’re doing or what you’re looking at. Want to know the weather right now? You won’t have to find the weather app and click on it to get a report. Weather apps for Google Glass will know when you’re looking up at the clouds and provide you with an instant weather report. If you’re unsure of what’s at a particular street address, look at the premises and Google Glass will tell you who’s inside, and possibly even show you the indoor plans along with a 360° panorama view if it’s a business. 2. Google Glass introduces absolutely new way of computing, with a simple, voice-driven user interface that makes a number of tasks much more intuitive. There are some examples of these: 3. To start using Google Glass, you tap the frame of the glasses and you’re taken to the home screen. You don’t see a bunch of icons like on smartphone home screen, just a simple real-life scene you’re looking at. To issue a command, you tap the frame and say “OK Glass”. 4. After you issue the order “OK Glass”, you can instruct the glasses to do something specific by saying something like “take a picture”. That’s it. There’s no fumbling around looking for the camera icon. 5. Same goes with video. With Google Glass, you can record what you see without moving a finger. 6. Now this is what calls serious sharing — actually sharing what you see with your friends . 7.......

One Night

...would go away. As I am in my window I start to feel my house lift from the ground swirling round and round. I ran to my parent’s bedroom to make sure they were alright; attempting to open up the door they seemed to be a strong force preventing me from getting in so I yelled mom/dad as loud as I could but there was no response. Next I sprinted down the stairs to my brother’s room and tried to open the door but his was locked. Feeling hopeless and afraid I ran back to my bedroom and got underneath my covers. I started to pray that this was all a bad dream that I would soon wake up from, the rain came to a halt and the winds began to settle. As I pulled the covers from off of my head, then got out of the bed to go the window I notice clouds of fog surrounding the house. What I thought was a bad dream was not so bad after all; there were stuffed animals and candy everywhere. I notice that when I walked it was as if I was floating on thin air like there was nothing beneath me. Everything was in slow motion, I thought to myself wow is this what every kid experiences the night before they turn 6 years old. As I am starting to feel a sigh of relief I was awaken by my entire family and friends singing happy birthday. They were carrying my birthday cake into my bedroom with big stuffed animals, toys and candy. I must say I’ve had a lot of crazy dreams, but this is one I will never...

...“Rain, rain go away, come again some other day.” On September 9, 2012 as I sat on the beach with my family for their annual so long to summer picnic, dark clouds rolled in and it started to rain lightly. We were at first amused at the situation, but then had to decide whether to pack up and leave or stay and make the most of the day. Some sheltered under the beach umbrellas, while others shredded their clothes and went out into the rain in their bathing suits. The situation was amusing but frustrating. We laughed and wondered how it was that they could be so wrong sometimes and then hit it on the head at other times. In a matter of one hour the dark clouds and rain moved northward and the sun was shining brilliantly. . While I watched the skies and ocean, and felt the windswept sand hit my body, it came to mind that the weather and how it affects us would be a great career choice. Since I was young, I had an interest in the weather. Every morning I would look at the weather predictions to determine how to dress, and what outdoor activities I would be able to do. I am a skateboarder, and in the summer I go to the beach frequently, so the weather does affect the planning of my day. The weather is interesting, dangerous, and can be life altering for some people. Used as an event planner for many day to day activities, for agriculture, flight planning, fishing excursions and even planning military maneuvers, the weather is an important factor in our lives.

...Sleet forms when there is a layer of above freezing temperatures below cloud base but the temperatures at the surface are below freezing. A snowflake falling out of the cloud will melt in the above freezing layer producing a rain drop. The below freezing surface layer must be thick and cold enough to refreeze the raindrop before reaching the ground. Hail is produced inside a cumulonimbus cloud by accretion of super-cooled liquid water onto a large frozen embryo caught in a strong updraft. Continuous cycles through areas of super-cooled liquid water will cause the hailstone to increase in size until it can overcome the upward vertical velocity and eventually fall to the earth’s surface. What is the difference between freezing rain and sleet? Freezing rain is liquid (super-cooled) that will freeze on contact with objects that are below freezing on the surface. The determining factor between sleet and freezing rain as a precipitation type, is the depth and coldness of the subfreezing layer near the surface. Sleet is usually a transparent or translucent ice ball around .2 inches or less in diameter. When it hits the ground it can bounce. The formation of sleet was discussed in the previous question. Describe how hail might form in a cumulonimbus cloud? Hail is formed when clouds, specifically cumulonimbus clouds, have both high altitudes and powerful updrafts within the condensation layer of the cloud. As rain droplets form, they are frozen and then carried aloft......

...can alter your results. For my weather diary I made sure I took the temperature at the same time every day as to get true, comparable results. To keep consistency in my results I also took the temperature using the same thermometer each time, and took the readings from the shade, rather than somewhere in direct sunlight, which could have given a fake result, as the temperature readings could have been higher as they were I the sun. this helped me complete my weather diary, as it allowed me to see the temperature of a number of weeks and use it as comparable data, in other areas of the weather diary, such as pressure and cloud cover. Cloud cover and cloud types were another fieldwork technique used to complete my weather diary. By looking up into the sky, in the same place and the same time every day I was able to roughly give a result in oktars of how much cloud cover there was on a particular day. As...

Clouds and the Apology

...traditions, although in a way that argues against it which is irritating to some. He claims that without him the state is likely to enter into a “deep sleep” meaning that it would be forgotten. In Aristophanes’ Clouds, he treats Socrates crudely because its purpose is for Just Arguments whereas Socrates used Unjust Arguments. In The Apology, Socrates gives a speech defend himself and his conduct. He says that since he has no experience with the law courts he is going to talk in the manner he is most used to: honestly and directness. He explains that his conduct was because of the Delphic oracle who said that he was the wisest of all men. Knowing that he doesn’t know much of world affairs, he concluded that he is only wiser than other people only in that he knows nothing. To spread his wisdom he goes around to question “wise” men to expose their ignorance. Although he earned the admiration of young Athenians, hatred ensued from the people he embarrassed which would be the reason he was on trial. He says that he is merely a gadfly stinging a lazy horse which is the Athenian state. Claiming that without him Greek traditions would be forgotten and that through his interactions, even if it is irritating to some, it can be used to become a productive and virtuous action. In The Clouds, Aristophanes writes about a how a father, Strepsiades, worries over the financial issues due to his son’s, Pheidippides, financial spending. In order to outdo the creditors through an “Unjust”......

A Tornado in the Night

...The long summer day had been filled with dark and gloomy clouds. The air was so thick I could hardly breathe. My pajama's clung to my body as if I had just been sprayed with the garden hose. I remember thinking that I wished that it would just hurry up and rain already. The next thing that I remember is running to my parent's car in the middle of the night. With the distinctive loud wail of a tornado siren, the wind howling, and lightening filling the dark sky, I have never been so afraid in my life. The loud tornado siren was not something new to me, even though it frightened me every time that it went off. Most times, though, it was just going off for a weekly test and was not in the middle of the night. That night it was no test. It was the real thing. We had to jump into the car for the short drive to my memaw's house, running over my dog Joe in the process. Even though my memaw only lived a mile away, the drive seemed to take forever. Would we ever reach her house and the safety of her cellar? I have never run so fast in my life as I ran that night, from the car to the ground cellar in the back yard. The wind was blowing so strongly that I felt as if I wasn't moving at all. The lightening filled the dark cloudy sky and, all I could see was the shadow of my silhouette on the ground in front of me. Loud thunder clapped in my ears and made me shudder, the ground shaking under my feet. Finally, I felt relief and fear at the same time as I reached the cellar door. I......

...A close brush with death It was raining cats and dogs. Fortunately we were in a car and my uncle, who was driving, had the situation under control. We passed slowly by an oil-palm estate. The driving rain made visibility poor. So my uncle drove very carefully. He had all the lights on. So did the other drivers. I could make out little blobs of light on the other cars through the white sheet of rain. Overhead, black clouds hovered ominously. It felt as though they were about to fall on us at any moment. Lightning streaked across the sky and onto the distant hills. The ensuing thunder rumbled unceasingly. Some flashes of lightning came uncomfortably close and the resulting thunderclap was deafening, even with all our windows up. All of a sudden a bright flash of light blinded us and a very loud crack made me lose my bearings. The next thing I knew was that my uncle had stopped the car and his face was pale with shock. I too was in shock. What had happened? For a long agonising moment I struggled to collect my scattered wits. Then my uncle pointed a trembling finger at something outside the car. I looked in the direction and saw an oil-palm some ten metres away literally split in half through the middle. It was scorched black and smoking. I then realised that it had just been struck by lightning. If the lightning had struck us instead, we would be scorched black and smoking too. Still trembling, my uncle quickly drove away from the danger zone. We had just......

...The Nature of Clouds Scott Tully Thomas Edison State College Abstract Clouds are formed when moist air is cooled sufficiently for its water vapor content to reach saturation, followed either by condensation to form water droplets, or by deposition to produce ice crystals. Usually the cooling occurs when relatively warm air from near the ground is carried up and expands into colder, lower pressure levels higher in the atmosphere. The formation of droplets or crystals normally require the presense of tiny airborne nuclei in the atmosphere, which serve as sites for condensation or deposition to occur. There are various mechanisms that drive this movement and each gives rise to a distinctive set of cloud types. The type and strength of the uplift can result in anything from benign cumulus or cirrus clouds to violent cumulonimbus storm clouds. With rare exceptions, clouds exist entirely within the troposphere, the lower layer of the atmosphere. I have put together this cloud chart to provide examplees of various cloud formations, and explanations of their creation. Low Level Clouds Low-level clouds are found below 6,500 feet and although they are mostly made up of water droplets. They can also be composed of ice particles and snow in very cold temperatures. Stratus clouds are among the low-lying clouds. They are gray clouds that cover the entire sky and can be the result of very thick fog lifting in the morning. Nimbostratus clouds are dark gray clouds that produce......
