Cloud computing involves computing over a network, where a program or application may run on many connected computers at the same time. It specifically refers to a computing hardware machine or group of computing hardware machines commonly referred as a server connected through a communication network such as the Internet, an intranet, a local area network (LAN) or wide area network (WAN). Any individual user who has permission to access the server can use the server's processing power to run an application, store data, or perform any other computing task. Therefore, instead of using a personal computer every-time to run the application, the individual can now run the application from anywhere in the world, as the server provides the processing power to the application and the server is also connected to a network via internet or other connection platforms to be accessed from anywhere [33]. All this has become possible due to increasing computer processing power available to humankind with decrease in cost as stated in Moore's law.

In common usage the term "the cloud" is essentially a metaphor for the Internet.[1] Marketers have further popularized the phrase "in the cloud" to refer to software, platforms and infrastructure that are sold "as a service", i.e. remotely through the Internet. Typically, the seller has actual energy-consuming servers which host products and services from a remote location, so end-users don't have to; they can simply log on to the network without installing anything. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network.[2] Google, Amazon, IBM, Oracle Cloud, Rackspace, Salesforce, Zoho and Microsoft Azure are some well-known cloud vendors.[3]

Network-based services, which appear to be provided by real server hardware and are in fact served up by virtual hardware simulated by software running on one or more real machines, are often called cloud computing. Such virtual servers do not physically exist and can therefore be moved around and scaled up or down on the fly without affecting the end user, somewhat like a cloud becoming larger or smaller without being a physical object.

...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. Lost...

First floor apartments were flooded and vehicles were swallowed by high waters after 5.91 inches fell in Louisville on Saturday alone, according to the Weather Channel. Flooding closed at least 45 roads. Authorities say more than 80 people were rescued or evacuated thanks to seven-inches of rainfall that fell in 36 hours. NBC's Kerry Sanders reports. "I was lying there sleeping, kids woke me up, looked out, I couldn't believe it," evacuee Vickie Dedrick told NBC affiliate WAVE in Louisville. "Just a little bit of water on the road, next thing you know it looks like a tidal wave come through; looks like all cars washed off," added evacuee Mark Elliott.

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...

...condenses it releases heat * Warm air is less dens than cold air, the added heat will make the rising air continue in an updraft * If updrafts push air high enough into the atmosphere, the water droplets freeze in the tops of cumulonimbus clouds( tall clouds that rise to high altitudes and spread to form wide, flat, anvil-shaped tops. * Cold air pushing under warm air is a common mechanism triggering system for these storms * Thunderstorms average 24 kil across but can travel as much as 1000 killometers * Lightning is a result of a charge separation from the top and bottom of the cumulonimbus clouds * Charge separation increases as particles are carried in updrafts toward the top of the clouds and collide with the downwards moving ice particles or hail * Enormous electrical separation or potential between different parts of the cloud and between the clouds and the ground. * Electrical resistance cannot keep the opposite charges apart and the positive and negative charges rejoin and with an electrical lightning stroke * Cloud to ground lightning is generated when charged ions in a thundercloud discharge to the best conducting location on the ground * Lightning strikes from cloud to cloud to equalize its charges * Lightning is visible because of the difference between the speed of light and the...

...“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. In addition...

Meteorology

...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 again...

The Reserach

...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” argument he...

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 climbed...

Hello

...Cirrus clouds are the most common of the high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of Cirrus clouds you can tell from which direction weather is approaching. When you see Cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours. Cirrostratus clouds are thin high clouds that often cover the entire sky. They are so thin that the sun and moon can be seen through them. Cirrostratus clouds usually come 12-24 hours before a rain or snowstorm. Cirrocumulus clouds appear as small, rounded, white puffs that appear in long rows. The small ripples in the Cirrocumulus clouds sometime resemble the scales of a fish. Cirrocumulus clouds are usually seen in the winter and indicate fair, but cold weather. In tropical regions, they may indicate an approaching hurricane. Altostratus clouds are gray or blue-gray middle level clouds composed of ice crystals and water droplets. These clouds usually cover the entire sky. In the thinner areas of the cloud, the sun may be dimly visible as a round disk. Altostratus clouds often form ahead of storms that will produce continuous precipitation. Altocumulus clouds are mid level clouds that are made of water droplets and appear as gray puffy masses. They usually form in groups. If you see Altocumulus clouds on a warm, sticky morning, be prepared to see...
