Pros and Cons of Cloud Computing Essay Example for Free

Pros and Cons of Cloud Computing Essay With the unprecedented growth and spread of information, there is no wonder why large Information Technology companies have been investing in the â€Å"cloud†. To expand, when referring to Cloud Computing, this means to access and store information not stored with in your computer whether it be public, private, or hybrid cloud computing. In technological terms, the server you are accessing is somewhere else and therefore, the information and tools you are using are â€Å"up in the clouds† but more so stored in another server space. However, whether you are paying for services through software, total usage, or free usage (hence the types of cloud services) Cloud Computing seems to be everywhere. Yet, it is important to recognize what is to gain by using cloud computing from big businesses to individual users and what are some risky moves when utilizing cloud storage over the Internet. Hence, the content of this paper will discuss the pros and cons of cloud computing and where cloud computing is headed in todays online society. Discussion: Moving forward, large companies use private cloud computing on the grounds that it is far more affordable to store and run programs in a server space designed for processing, saving and running information applications and so on. The biggest noticeable advantages in cloud computing have to be the ease of running programs with out installing any new applications (since the provider installs it for you in their cloud), and payment depends on membership, and which billing method you chose; for example, monitored payment or a flat rate (Mitchell). However, there are competing companies such as Google Apps Marketplace, Windows Azure, Amazon Web Services, Success Factors, and so on, that make cloud computing affordable on different user levels. These levels range from individual interest to larger company interests. For example, a company may need thousands of gigabytes worth of storage while I may need a few gigabytes of storage. So when paying for space I will be able to only buy what I need. Additionally, using the cloud allows a user greater mobility since an individual with an account can access the cloud from any computing device (laptop, desktop, tablet, or phone) that has available Internet access. More importantly, it’s easier for multiple users to access the same document and not overload the system and backs up data without someone having to worry about the location. Therefore, utilizing a third-party system server, Cloud Computing perks offer cheaper, reliable storage and retrieval of information. Figure [ 1 ] Although Cloud Computing sounds like a convenient service for businesses and users to take advantage of, there are downsides for paying or using cloud servers. Instances include, system shut downs for maintenance, access of data after canceling a membership, and more importantly privacy. Yet, a simple downside would be â€Å"What if someone uploads data into the cloud server and suddenly loses Internet connection?† The answer would be lost time and an incomplete data upload, not to mention the hassle of finding Internet connection again to access the cloud’s server only to attempt to upload the same work once more. On the other hand, looking back at the 2011 Google Docs incident, when an outage delayed user interaction for an hour starting in the UK and then reached the US (McCaney). Many organizations and people couldn’t access or exchange files via the cloud. So accidents happen, and although people lost out on time and information sharing, no files were reportedly lost. Even so, accidents including shutdown to outages, are rare natural occurrences, yet, inevitable for the current time. Not only are there outages to worry for also, according to Hamad Subani, he asserts that â€Å"Since most of the major Cloud Computing servers are operated by companies based in the United States, data you put on your Cloud is subject to American law.†   Which is also true since authorities only need to file a subpoena to get the information, yet, once information is shared warrants are needed and such (Subani). Hence, privacy is compromised, but to an extent. If someone is engaging in illegal file transfers on a cloud server, it already violates the consumer to provider contract; therefore a person is better off keeping their illegal activities to themselves. Other than that, cloud computing is relatively safe. | Cloud Computing Simplified| Pros| Cheap services, reliable, extra storage space, no worry about the server location| Cons| No privacy, and you must have internet access, maintenance. | After going through the pros and cons of cloud computing, it is necessary to analyze where such services are headed in the near to distant future. According to Brian Donaghy,   Ã¢â‚¬Å"Market Research Media says the cloud market will reach $270 billion in 2012 and Gartner predicts it will be over the $148 billion mark by 2014, much greater than Forrester’s forecast of over $118 billion for the same year.† Without a doubt, cloud computing will continue to rake in the profits since increasing needs for IT services are inflating the cloud’s development. In perspective, social networks (like YouTube or Skype) outsource their work to cloud services to help store user data. More so, it seems as if digital life is linked to the storage systems of cloud servers. Think about it, with out a back up storage in the cloud, there wouldn’t be a free YouTube, Tumbler, and blogging would essentially be news posts by big businesses. Cloud computing will continue to advance in ways that further accommodates all online users. About the only disadvantage of this are those with out Internet connection, the people left out of the Internet community. However, for the time being, cloud computing’s growth in the United States and American websites using cloud resources, prove to be helpful in the spreading of information from social to private perspectives of data usage. Conclusion: Hence, it is evident that cloud computing will be growing exponentially so long as the Information Technology sector continues to be in high demand. Therefore it is up to the consumers individual needs to decide if cloud computing would help them keep tabs with their data usage online or if using their own memory on their computer is a better decision. On the other end, companies should use Cloud Computing servers as a cheaper form of Information Technology management. Especially since investing in a mainframe computer would be far more costly than having some other company do all the work for you for a smaller fee. Therefore, cloud computing will definitely be a primary factor in the growth and facilitation of online data usage and continue to revolutionize modern technology.

â€Å"The sandy beach is a harsh, constantly changing environment,† explained by the UKMCS (2). This is the ocean is constantly moving because of the wind in the earth’s atmosphere (Crawford 4). Along the edge of most coastlines, a commonly found zone is an estuary (Marine Conservation Society (UK) SouthEast 1). This is where brackish waters, an area where freshwater is released and mixed with the ocean’s salt water, is created (1). However, even though there are small amounts of freshwater added, this does not change that the salinity of the ocean is remarkably high. Salt is carried into the ocean by rain, rivers, streams, and underwater volcanoes (Office of Naval Research 3). Because of the multiple sources of salt, the levels of salinity within the ocean shoot up rapidly. The Office of Naval Research states, â€Å"Salinity is expressed by the amount of salt found in 1,000 grams of water† (3). Marine ecologist created an expression for the amount of salt inside a given area. If there is one gram of salt within 1,000 grams of water, then it is represented as 1 pound per ton (3). The oceans salinity varies between about 32 and 37 ppt (3). Most humans would not be able to live in an ecosystem with salinity levels being this high, however some organisms have adapted to surviving is such an environment. Osmosis is an animal’s way of adapting to different types of salinities (Office of Naval Research 3). All marine mammals have special traits that they adapted to help them survive in or around marine habitats (Marietta College 1). As prompted by the Marietta College of Ohio â€Å"Many organisms in saltwater are osmoconformers.† (1). An osmoconformer is an organism that has the same concentration of salt within its body as the surrounding water (1).... ...terials into the water and can threaten organisms (1). Most NSP is located close to people’s homes. Most importantly is the hazard material that is used and not properly cleaned or disposed of. If people have a septic tank on their property, and it is not the correct size, they can leak and pollute surrounding ground water (1). Poisonous materials from cars and other vehicles such as oil, brake fluid, grease, and gasoline, can be washed off and channel into storm drains, giving them direct access to the ocean (1). If it is not being washed off, then another large problem is when it is spilled or dumped out (Hemminger 4). These products can be picked up by rain and pushed down into storm drains (Natural Resources Defense Council 1). The last most common NSP is when non-degradable products are flushed down the toilet, which can damage the sewage treatment process (1).

Research and Statistics

HYPOTHESIS A hypothesis is a formal tentative statement of the expected relationship between two or more variables under study. Definition: A hypothesis is an assumption statement about the relationship between two or more variables that suggest an answer to the research question. OR Good & Hatt define hypothesis as shrewd guess or inference that is formulated and provisionally adopted to explain observed facts or conditions and to guide in further investigation. Importance: ? Hypothesis enables the researcher to objectively investigate new areas of discovery. Hypothesis provides objectivity to the research activity. ? It also provides direction to conduct research such as defining the sources and relevance of data. ? Hypothesis provides clear and specific goals to the researchers. ? Hypothesis provide link between theories and actual practical research. ? It provides a bridge between theory and reality. ? A hypothesis suggests which type of research is likely to be most appropriate. ? As it is tentative statement of anticipated results. ? It stimulating the thinking process of researcher as the researcher forms the hypothesis by anticipating outcome. It also determines the most appropriate research designs and techniques of data analysis. ? Hypothesis provides understanding to the researchers about what to except from the results of the research study. ? It serves as a framework for drawing conclusions of a research study. ? Without hypothesis, research would be like aimless wandering. Characteristics of a good hypothesis: The main characteristics of a good hypothesis as follows: ? Conceptual clarity: Hypothesis should consist of clearly defined and understandable concepts. Hypothesis can be stated in declarative statement, in present tense. Empirical referents: A good hypothesis must have empirical basis from the area of enquiry. ? Objectivity: Hypothesis must be objective, which facilitate objectivity in data collection. ? Specificity: It should be specific, not general, and should explain the expected relation between variables. ? Relevant: The hypothesis should be relevant to the problem being studied as well as the objectives of the study. ? Testability: Hypothesis should be testable and should not be a moral judgement. ? Consistency: A hypothesis should be consistent with an existing body of theories, research findings, and other hypothesis. Simplicity: A hypothesis should be formulated in simple and understandable terms. ? Availability of techniques: The researcher must make sure that methods are available for testing their proposed hypothesis. ? Purposiveness: The researcher must formulate only purposeful hypothesis. ? Verifiability: A good hypothesis can be actually verified in practical terms. ? Profundity of effect: A good research should have profound effect upon a variety of research variables. ? Economical: The expenditure of money and the time can be controlled if the hypothesis underlying the research undertaken is good. Sources of hypothesisHypothesis in research study cannot developed merely with wild guesses or assumptions , but they are generated from variety if sources such as theoretical or conceptual Frameworks, previous research findings,real life experiences and academic literature. ? Theoretical or conceptual frameworks: the most important sources of hypothesis are theoretical or conceptual framework developed for the study. Through a deductive approach these hypothesis are drawn from theoretical and conceptual framework for testing them. ? Previous research: findings of the previous research studies may be used for framing the hypothesis for another study. real life experiences: real life experiences also contribute in the formulation of hypothesis for research studies. ? Academic literature : it is based on formal theories, empirical evidences, experiences, observation and conceptualization of academicians. TYPES OF HYPOTHESIS Simple an complex hypothesis: Simple: It is a statement which reflects the relationship between two variables Complex: It is a statement which reflects the relationship between more than two variables. Associative and causal hypothesis: Associative: It reflects the relationship between variables that occur or exists in natural settings without manipulation.Causal: it predicts the cause and effect relationship between two or more dependent and independent variables in experimental or interventional. Directional and non directional hypothesis: Directional hypothesis: It specifies not only the existence, but also the expected direction of the relationship between variables. Non directional hypothesis: It reflects the relationship between two or more variables, but it does not specify the anticipated direction and nature of relationship such as positive or negative.Null and research hypothesis: Null hypothesis (H0):It is also known as statistical hypothesis and is used for statistical testing and interpretations of statistical outcome. Research h ypothesis(H1): It states the existence of relationship between two or more variables. Conclusion: The formulation of hypothesis plays an important part in the growth of knowledge in every science. Hypothesis converts the question posed by the research problem into a declarative statement that predicts an expected outcome. Bibliography: [pic]
