CLOUD COMPUTING

Cloud computing is the term which use for delivering internet services. The word cloud is a actually is a symbol which used as a diagram or flowchart to understand the cycle and how it works. Cloud computing is based on three different pillars such as infrastructure, software and platform.

Cloud computing can also be understand with the help of the examples of Yahoo, Hotmail, Gmail or for that reason all most of the social networking sites a user dont need any software or highly equitably rooms all they need is internet connections with which they can connect with those sites and they can chat or email to one and another all the software or interface are in cloud.

Cloud computing works differently then usual or traditional way it has mainly three characters and all these three mirrors are favorable for the users.

1) it has a demand a supply balance will be supply as much of user need.

2) it supply on minute to minute or hourly bases again for the convenience of users timing.

3) it depends on consumer as much or as little they want be provides.

An era where consumer often struggle with the speed and data distribution problem at this time when consumer scared to spend on software this brainy innovation not only resolving the demand and supply problem not only meets the demand of users but also providing the economical users don't have to spend on software or any team to use these services.

Cloud computing this service is could be for any one from home user to professional, from public sector to private Amazon web services is the largest service provider to general users as of now for private user provider s stick to a particular group or company however who ever is providing to any consumer the aim is to provide the services which consumer demand.

CLOUD COMPUTING END-USER ANALYSIS- MEXICO

Most of the major factors driving adoption of the cloud computing concept by companies in Mexico are the same ones that boost more markets such as the USA and Western Europe.Fortunately for the Latin American and Caribbean region, countries such as Brazil,Colombia and Chile were not so effected by the economic crisis as some other economies, prompting initial Cloud computing investments already in 2009. The implicit cost reduction that the Cloud computing pricing model suggests is seen by both CIOs and CFOs as one of the strongest drivers in the Latin American and Caribbeans region.The decision to explore cloud computing was primarily driven by economics.

Cloud Computing is flexible and scalable shared and /or private environment in which third-party supplier or in house architectures use virtualization technologies to create and distribute computing resources on as needed basis, via the Internet browser.

SHALL WE TRUST IN CLOUD COMPUTING ?

      Cloud computing has opened a new frontier of challenges by introducing a different type of trust scenario.Today' the problem of trusting cloud computing is a paramount concern for most enterprises.It's not that the enterprises don't trust the cloud providers' intensions; rather, they question cloud computing's capabilities.The challenges of cloud computing doesn't lie entirely in the technology itself.The dearth of customer confidence also stems from a lack of control over data assets, and unclear securityassurances.The adoption of cloud computing came before the appropriate technologies appeared to tackle the accomplanying challenges of trust. This gap between adoption and  innovation is so wide that cloud computing consumers don't fully trust this new way of computing.To close this gap, we need to understand the trust issues associated with the cloud computing from both a technology and business perspective. then we'll be able to determine which emerging technologies could best address these issues.

    Broadly speaking, trust means act of faith; confidence and reliance on something that's expected to behave or deliver as promised.we trust a system less if it gives us insufficiant information about it's expertise.The claims such as "secure cloud' or "trust me" doesn't help much to boost the trust level of consumers unless sufficient information is presented with the services.New technology must gradually build it's reputation for good performance and security.

THE TECHNICAL PRINCIPLE OF CLOUD SECURITY

Cloud Security is a new noun evolved from cloud computing .Cloud Security plan reflects the latest information Security of network times. It includes parallel processing, grid computing, unknown viruses judgment and other new technologies and concepts. Through the detection of the software network behavior via the grid, it obtains the latest information of the Internet Trojan horses, malicious software and to do automatic analysis and processing by sending them to the server, and then distribute the solutions of the viruses and trojans to every client-side. Because the antivirus software in future will not be effective in treating with increasing numbers of malicious programs, the main threat from the Internet is still computer viruses, malicious software and trojan horses.In this case,the method of using the feature database to do identifying job is out of date abselutely. The applications, identification and killing the virus of Cloud security technology no longer just depends on the virus database of a local hard disk, but rather to do collection, analysis and processing in time with the help of the huge network service. In short, the Internet is a huge "antivirus software". The more the participants are,the safer each participant is , and the whole Internet will be much safer.

CLOUD PRIVACY AND KEY FACTORS IN PRIVACY PROTECTION

                The cloud will typically process and store the information about which privacy is a paramount concern.the main issue is identity, which serves as the basis of privacy or lack of it, and underlines the trust of individuals and organisations in other entities. The key consideration is the intefrity that organisations adopt when handling personal information. From an organisation's perspective, control over information should remain with the end user or the data's creator with adequate controls ove4r repurposing.From a personal perspective, the person should have the wherewithal to control his or her identity as well as the release of socially sensitive identity attributes. Who owns the data?Is the person about whom the data pertains?Is it the organisation that prototypically stores tha data? Or, is it the cloud provider that physically stores the data somewhere out in cyberspace? As an example, is your financial information (as personal data) your property or is it uour bank's business property?

One of the beneficial aspects of the present concern over the information privacy is that it places the person about whom data are recorded in proper perspective.Whereas such person may be the object in an information system and is regarded as the subject in privacy protection.and that subject is intended to imply that a person should in fact have some control over the storsge of personal information.

More specifically, the subject is the person ,natural or legal, about whom the data are stored. The beneficial user is the organisation or individual for whom the data is performed, and the agency is the computing system in which the processing is performed and the information is stored. For example, the agency may be the service conmpany and the subject is the creditor.

In general, the beneficial user obtains the value from the data processed and has some control over the manner and time span in which the processing is performed. The agency need to be aware of the end use of the information or how and when the processing is performed.

The heart issues is the privacy protection, which normally refers to the protection of rights and individuals. While the concept may also apply to individuals, the individual aspect of the issue is that which raisess questions of privacy and liberty.

ADVANTAGE OF CLOUD COMPUTING

The Benefits of Cloud Computing
some of the advantages to using cloud computing for different types of  companies as follows

• cloud computing provides lots of flexibility to the user.  meaning of clous computing is to allow the staff to access the files and data that they need even when they're working remotely and/or outside office hours.
• cloud computing is easily accessable if there is internet it can also used from smart phone such as Black Berry or iphone.
• Cloud computing helps to make everyone together even though physically ther are not Documents can simultaneously be viewed and edited from multiple locations.
• in compair to others downloading software through cloud computing in much easier , cheaper, and less labour intensive for companies.There is no need to buy and install expensive software because it's already installed online remotely and you run it from there, not to mention the fact that many cloud computing applications are offered free of charge. The need to pay for extensive disk space is also removed

With cloud computing, you subscribe to the software, rather than buying it outright. This means that you only need to pay for it when you need it, and it also offers flexibility, in that it can be quickly and easily scaled up and down according to demand. This can be particularly advantageous when there are temporary peaks in demand, such as at Christmas or in summer, for example.

"A major advantage of using cloud computing for many companies is that because it's online, it offers virtually unlimited storage compared to server and hard drive limits. Needing more storage space does not cause issues with server upgrades and equipment - usually all you need to do is increase your monthly fee slightly for more data storage."

FEATURES OF CLOUD COMPUTING

The features of cloud computing are talked about under:

1 .VLDB :

The clouds had a certain scale, Google cloud computing has made more than 100 ten thousand servers, Amazon IBM and Microsoft Yahoo clouds have  thousands of server .Enterprise private cloud generally have  thousands of server. Cloud can give users unprecedented computing power.

2.Virtualization :

Cloud computing support users in any position to use all kinds of terminal for application service. the requested resources from cloud, rather than a fixed tangible entity .In the cloud application running,  in fact, user need not know and  worry about the location of application.They oly need a laptop or a mobile phone to meet our need through network service everything, even including supercomputing such task.

3.Reliable:

Using the data cloud computing node copy more fault-tolerant isomorphism interchangeable measures to guarantee service of high reliability.It is more reliable to use cloud computing than using the local computer.

4.Security:

Security provided by cloud computing is sweet for the reason that information over right here is centralized. Te centralization of knowledge improves the safety on the centered resources. The safety provided by this computing service is means better than the safety provided by different conventional systems.

5.Extensibility:

The scale of the cloud can be dynamic expansion, and meet the user  growth needs.

These great features of cloud computing make it the primary choice of the users.
