  • 1.Cloud Computing An Introduction

2. Cloud Computing Cloud Computing in simple terms is anything that involves delivering hosted services over the Internet. It is essentially a computing technique that processes data online located on the cloud. Cloud Computing is a combination of a large number of attempts at large scale computing with seamless access to virtually limitless resources. The cloud is where you put all your data including files and software so you can access it from any device, anytime, anywhere. 3.

Why Move To The Cloud? 6. Reduction in Expenditure - With no requirement of servers, businesses using cloud have significantly cut down their cost expenditure. Communication and Collaboration - With cloud in place, work can be accessed from virtually anywhere on any device allowing you to collaborate easily. Leading companies collaborate across the organization and eco-system using the cloud. Enables Quick Expansion of Businesses - Cloud technology offers the opportunities which helps in diversification and expansion of a firm. It fosters business growth as trendsetters say that the cloud allows innovating products and services rapidly. Analytics is the Way Forward - Businesses are relying on analytics to get their decisions right and the cloud aids them in this. Of all the successful organizations , nearly half use big data to get the insights and further shares the information seamlessly over the cloud. One Stop Shop for Businesses - Cloud fulfills every business need ranging from messaging to storage, cloud has it all. With the help of cloud, companies are able to build a strong bond between technology and business outcomes. 7. Reasons For Moving To Cloud Insights By IBM 8. Where Is The Cloud Going? 9. Gartner predicts that the bulk of new IT spending by 2016 will be for cloud computing platforms and applications with nearly half of large enterprise having cloud deployments by the end of 2017. Worldwide spending on public IT cloud services will reach $47.4 billion in 2014 and is expected to be more than $107 billion in 2017, according to a new forecast from IDC. Over the 2013-2017 forecast period, public IT cloud services will have a compound annual growth rate(CAGR) of 23.5%, five times that of the IT industry as a whole. 10. What Are The Different Types Of Cloud? 11. Private Cloud It refers to the cloud dedicated to single organization or customer. Public Cloud It is one which is shared among multiple customers and organizations. Hybrid Cloud Hybrid cloud is the customized combination of public and private cloud. Community Cloud It refers to the cloud dedicated between several organizations from a specific community with common concerns. 12. What Are The Different Cloud Services? 13. SaaS (Software-as-a-Service) Software-as-a-Service lets you access application over the Internet without installing it on your device. Some examples of SaaS: Google Apps Microsoft Office 365 Yahoo! Apps 14. PaaS (Platform-as-a-Service) Platform-as-a-Service lets you develop new applications in the cloud without buying hardware or software that do not depend on a specific platform to run. Some examples of PaaS include: Google App Engine OpenShift Microsoft Windows Azure 15. IaaS (Infrastructure-as-a-Service) Infrastructure-as-a-Service lets you rent cloud infrastructure e.g. servers, storage on demand, to run your software services. Some examples of IaaS : Google Compute Engine OpSource Amazon EC2 16. Cloud Computing Benefits 17. Location and Device Independence On Demand Service Cost Effective Easy to Implement Pay as you Go Feature Secure and Reliable Flexible and Scalable Next Generation Architecture 18. What Are The Barriers? 19. Anything but secure - Ever since its inception, security has been clouds Achilles Heel. The companies have tried every trick in the book to ensure that the cloud is safe, but to no avail. Compliance - Most of the people are reluctant to make a move to the cloud because they fear that the provider would not comply with the written agreements making their data and position highly insecure. Internet Dependence - The cloud providers claim that with your files in the cloud, you can access them from anywhere using the internet. But would you get seamless internet in every part of the world? If the answer to the question is negative, you have a food for thought. Provider Lock In - It has been found that most providers have a lock in period, which user have to complete no matter what. In such a scenario, the cloud becomes a bane. Data Is Not Owned By You - Providing your critical data to a third party doesnt sound too clever. But that is exactly what you have to do if you are pondering over moving to the cloud. 20. What Else Is Moving To Cloud? Traditional Banking to Internet Banking Traditional Mail to Web Mail Traditional Filing to Cloud Storage Traditional Shopping to Online Shopping 21. Conclusion Cloud Computing is an important stage in the development of IT systems, comparable with the emergence of the mainframe, minicomputers, microprocessors, and the Internet that will lead your business to success. Cloud is not perfect yet, and lacks in terms of security. But at the end productivity always prevails. 22. Thank You!Your Feedback is Important! 23.
