Doç. Dr. Ecir Uğur KÜÇÜKSİLLE Bulut bilişim, kişisel bilgisayarlar üzerindeki işlem yükünü hafifleten; bilgiye istenilen zaman ve mekânda, talebe bağlı olarak erişime imkân sağlayan bir teknolojidir. Bulut bilişim, işlem olanaklarını genişleterek şahıslara, küçük ya da orta ölçekli şirketlere bir dizi güçlü servise internet üzerinden erişim imkanı sunar. Teknolojik altyapı olmaksızın bir eğitim ortamının oluşturulması mümkün değildir. Bu nedenle çoğu eğitim kurumu bir ya da birden fazla sunucudan oluşan veri merkezlerine sahiptir. Servis altyapısının zaman içerisindeki kullanımında tahmin edilebilir ya da ani artışlar meydana gelebilir. Bu durumda kurum içi esnek olmayan altyapılar yetersiz

    4 XII December 2016 www.ijraset.com Volume 4 Issue XII, December 2016 IC Value: 13.98 ISSN: 2321-9653 International Journal for Research in Applied Science & Engineering Technology (IJRASET) Cloud Computing in India: Challenges, Progress and Future Shraddha Kulkarni Computer Engineering – Third Year, LDRP-Institute of Research and Technology, KSV University, Gandhinagar, Gujarat Abstract— Cloud Computing is one of the emerging fields of Technologies in today's time. In the recent times, it has taken the usage of Internet to an all together different level. The concept of 'pay-for-what-you-use' makes it completely affordable and flexible. India, due to its huge and strong IT Industry has been one of the major markests for all the Cloud providers. This paper presents the current scenario of Cloud services in India, the steps taken for its advancement in the main working sector and where it stands compared to other countries. It also highlights the major points that hinder India from using this Technology which majorly includes the Privacy and Security issues. Citing the advantages, even the government has been taking steps to utilize the benefits of the Cloud in the country. Keywords— Gartner Report, Data privacy, Cybercrime, Internet connectivity, Meghraj, ERP. I. INTRODUCTION Cloud is an acronym of the phrase: Common, Location-independent, Online Utility that is available on Demand. Cloud Computing environment provides internet based platform which are used for computer Technology. Cloud computing collects all the computing resources and manages them automatically. With the advancement of Internet, the Concept of getting everything online arose. Realizing this need, the big companies like Amazon, Google and Microsoft came up with a model called “Cloud Computing”, which can be termed as a highly innovative concept of utilizing different Hardware and software services independent of any platform at reasonable rates without any kind of risk involved.

  • The Cloud Changing the Business Ecosystem
    The Cloud Changing the Business Ecosystem kpmg.com/in Foreword Technology has always played the role of a disruptive force that somehow connects discontinuities and changes business models, ecosystems, or even the world order. Paradoxically, it has sometimes created a level playing field, and at times 'unfair' advantages for some countries or enterprises. This is evident all through out history right from the stone-age, to the industrial revolution, to the silicon era, to the internet/dot com age and to the current age of convergence/mobility. Technology could transform the world into the virtual space, enabling endless cycle of innovation. Advanced economies like US, UK, Germany, and Japan have been at the forefront of combining innovation and technology. This has enabled them to become superpowers that have the economical, defensive and financial muscle. Same has been the case with enterprises like IBM, Microsoft, Google, Apple, Siemens, Sony, CISCO, Nokia, etc. At the same time, it has created a level playing field with the rise of telecommunications and the internet. This leveling has helped in creating emerging leaders like India and China who are leveraging favorable demographics with technology. Technology is often a savior during the downward economic cycles as it enables the creation of more efficient business models and ecosystems. Ironically, sometimes it also leads to economic downturns as the euphoria over technology powered business models cause unrealistic expectations in the capital markets, creating bubbles which inevitably burst for e.g. the dot com burst. The Cloud is another such phenomenon that has stirred up interests and investments in many parts of the world.
