What is cloud computing? Cloud computing is a technology that uses the internet andcentral remote servers to maintain data and applications. Cloud computing allows consumers and businesses to useapplications without installation and access their personal filesat any computer with internet access. This technology allows for much more efficient computing bycentralizing storage, memory, processing and bandwidth. Cloud computing is the delivery of computing as a servicerather than product where shared resources, software andinformation are provided to users as an utility(like power grid)over network. 6. A simple example of cloud computing is Yahooemail, Gmail, or Hotmail etc. You dont need a software or aserver to use them. All a consumer would need is just aninternet connection and you can start sending emails. The server and email management software is all on thecloud ( internet) and is totally managed by the cloud serviceprovider Yahoo , Google etc. The consumer gets to use thesoftware alone and enjoy the benefits. The analogy is , If you need milk , would you buy a cow ? .Just to get this benefit (milk) why should a consumer buy a(cow) software /hardware? 7. picture of cloud 8. Characteristics of cloud computing Maintenance:- maintenance is easier , because they do not need tobe installed on each users computer and can be accessed fromdifferent places. Virtualization:- virtualization technology allows servers and storagedevices to be shared and utilization be increased. Device and location independence:-enable users to access systemsusing a web browser regardless of their location or what device theyare using (e.g:- PC, mobile phone). Application programming interface:-(API) accessibility to softwarethat enables machines to interact with cloud in the same way theuser interface facilitates interaction between humansandcomputers. 9. cloud service models Infrastructure as a service( Iaas ). Platform as a service( Paas ). Software as a service( Saas ). 10. Infrastructure as a service:-A consumer can get servicethrough the Internet. This type of service is calledInfrastructure as a Service (IaaS). Internet-based services suchas storage and databases are part of the IaaS. Platform as a service:-PaaS offers full or partial applicationdevelopment that users can access typically includingoperating system, programming language executionenvironment, database, and web server. Software as a service:-In this model, cloud providers installand operate application software in the cloud and cloud usersaccess the software from cloud clients. This eliminates theneed to install and run applications on the users system. 11. Deployment models Private cloud:-The cloud infrastructure is operated solely for Anorganization.Eg:-Amazon virtual private cloud. community cloud:-The cloud infrastructure is shared by severalorganizations and supports a specific community that has sharedconcerns.Eg:-Google apps for government. public cloud:-The cloud infrastructure is made available to thegeneral public. Eg:-Microsoft windows azure. Hybrid cloud:-The cloud infrastructure is a composition of two ormore clouds (private, community, or public).Eg:-VMware vcloud. 12. Fear of cloud What are the security concerns that are preventingcompanies from taking advantage of cloud? These problemsmay only become apparent after more widespread adoptionof cloud computing as a technology. Cheap data and data analysis:- The rise of cloud computinghas created enormous data sets that can be monetized byapplications such as advertising. Google, for instance, leverages its cloud infrastructure tocollect and analyze consumer data for its advertising network.Collection and analysis of data is now possible cheaply. Because of the cloud, attackers potentially havemassive, centralized databases available for analysis. Forexample, Google is essentially doing cheap data mining whenit returns search results. How much more privacy did one havebefore one could be googled? 13. New directions The core issue is that with the advent of the cloud, the cloudprovider also has some control of the cloud users data.Information-centric security:- In order for enterprises to extend control to data in the cloud, Data needs to be self- describing and defending, regardless of its environment. Data needs to be encrypted and packaged with a usage policy. 14. Privacy-Enhanced Business Intelligence:-A different approachto retaining control of data is to require the encryption of allcloud data. The problem is that encryption limits data use. In particular searching and indexing the data becomesproblematic. For example, if data is stored in clear-text, one can efficientlysearch for a document by specifying a keyword. This isimpossible to do with encryption schemes. Cryptography may offer new tools to solve these problems.Cryptographers have recently invented versatile encryptionschemes that allow operation and computation on the ciphertext. 15. What does a shift towards cloudcomputing mean? A paradigm shift to cloud computing will affect many differentsub-categories in computer industry such as softwarecompanies, internet service providers (ISPs) and hardwaremanufacturers. 16. Who gains? Internet-based companies that could gain from a shifttowards cloud computing include:-Amazon.com.Google.Microsoft. 17. Who loses out? Traditional software producers that could have somecatching up to do if cloud computing ultimately wins outinclude:-Oracle.SAP(system applications and products in data processing). 18. Cloud computing scenario 19. Latest updates of cloud computing A Microsoft-commissioned study, conducted by IDC, predictsthat cloud computing will generate over two million jobs in Indiaand nearly 14 million new jobs worldwide by 2015. More than50 per cent of these jobs will be generated in the small andmedium businesses. Within two months, Hewlett-Packard will offer a large andpowerful cloud computing service similar to Amazon WebServices, but with more business-oriented features, accordingthe head of the project. Today, Intel IT operates a massive, worldwide computingenvironment that supports about 78,000 Intel employees andincludes approximately 100,000 servers. 20. Conclusion Cloud computing is still struggling in its infancy, with positiveand negative comments made on its possible implementationfor a large-sized enterprise. Cloud computing holds some strong promises.Highly available.Dynamically allocate resources.Pay only for resources that u use. But of course there are pitfalls. Cloud computing might not bethe best solution for you. It depends on the size of yourcompany, your line of business. 21. Thank you.. </p>
