Cloud Computing Challenges and Concerns Dazhi Zhang Abstract Cloud computing is an internet-based storage and management computer. It is a flexible, efficient, economic, environment friendly IT technology. For these advantages and the big business value of cloud computing, thousands of companies and institutions in different industries have begun to use cloud computing technology. For the widely use of cloud computing, now we are in the age of cloud computing. How to deal with its challenges has become a problem we are feeling obliged to face, especially the security issues. This research paper will first describe some characteristics and definitions of cloud computing. In section two, I will show two kinds of patterns of cloud computing, …show more content…
Secondly, the diversity of enabling technologies supporting cloud computing and ongoing development make cloud computing changing fast. Thirdly, cloud computing is not a common knowledge for everyone. Some people still do not know it. Fourthly, the high exposure to the public highlights its functions and features, which weakens its nature. Finally, cloud computing technology is still developed by or institutions. It is very likely that those entities combining their own vision and benefits with cloud computing. So it does make a phenomenon that same definition with different ways to say. Generally speaking, cloud computing is a new service pattern that are provided to customers over network on leased basis and able to scale up or down their service requirements. It is a new kind of IDC (Internet Data Center). Cloud computing is very similar with traditional IDC. For instance, they have the same operating pattern. They both provide basic resource and leasing them for profits. Also, they have same target customers group. However, the main differences between IDC and cloud is the scale of resources, the ability of providing services, and the transparency of service. According to the definition of cloud computing determined by NIST, cloud computing has following main characteristics. First, cloud computing is a
Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any
Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.
cloud computing is a sort of on-interest registering strategy that lets clients use IT assets, for example, system, server, stockpiling, administration, application, so on through Internet when requiring them instead of owning them. Distributed computing can be considered as a whole of SaaS
As we all likely already know, there 's a lot of hype associated with cloud computing. Cloud computing encompasses diverse models and technologies. It is not just a paradigm or a concept that is forced into the enterprise by their thought leaders.
Cloud computing can be viewed as one of the most rapidly growing and evolving paradigm.Webmail,online storage and online documents are most famous examples in which customers can access their data via web browsers on the internet. The original idea of the cloud computing was delivered by J.C.R Licklider in sixties (Mohamed 2009). Cloud computing has developed since then and started to server the publics after internet offered a significant bandwidth in the nineties (Mohamed 2009). Cloud computing has been through many different phases and is still rapidly evolving.
ABSTRACT: Cloud computing is nothing but an internet based connection to remote servers which allows to store data and access to all services. These services are provided by the third party who owns the infrastructure. Cloud computing is classified into public, private or hybrid. It is a kind of grid computing. It is flexible and easy to adapt. Apart from advantages organizations are very slow in processing the customer resources because it has some security issues and challenges associated with it. Security is the main issue which is becoming a big hurdle for the growth of cloud computing. The companies are worrying to handle some important data to other companies due to these security challenges. This paper is going to give brief
Cloud computing is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure.[1] Example: Google application engine, Software as a Service (SaaS) where company host their data in cloud and user can access through internet. Example: Gmail, Facebook. Infrastructure as a Service (IaaS) is providing basic services. Cloud computing has four models first is public cloud services are available over a network that is open for
Cloud computing can be defined as the large-scale, shared IT infrastructure which is available over the internet it helps is transforming the way corporate IT services are delivered and managed.
Cloud technology innovation is emerging as one of the most popular issue for most IT practitioners and cloud computing is thought of as the future trend of development of the IT industry. According to Stanoevska (2010), enterprises should have an IT infrastructure that can reform itself rapidly to new business priorities. Cloud computing technologies, such as Cloud mail, Cloud platform and Cloud software services, provide an efficient work platform for enterprises. At the same time, Carling (2011) puts forward potential problematic issues in terms of the security of cloud computing. The future of enterprise cloud computing becomes increasingly controversial. Nevertheless, enterprises should base their future framework for Information and
Cloud computing refers to the hardware, systems software, and applications delivered as services over the Internet (Antonopoulos & Gilliam 2010, p. 3). According to the United States’ National Institute of Standards and Technology (NIST), cloud computing is a model for enabling network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. However, even with all of these definitions, cloud computing is still somewhat a very broad term to describe. Oracle CEO, Larry Ellison (2008) once said:
First of all what is cloud computing? Cloud computing is the storing of data and applications on remote servers, and accessing them via the internet rather than saving or installing them on your personal or office computer. In order to understand cloud computing lets divide the cloud computing into two parts. The first part is computing whenever there is a computing there is one word that comes to our mind that is nothing but a computer. Computer computes something computed that computes something with the help of processor and memory so whenever there is a word computing then this consists of processor and memory. Then we move into the second part what is cloud? Cloud is a different name that has been used for internet. It is a different
Cloud Computing is an internet based service provide your business an updated model that deliver you a software, data access and storage remotely over the internet.
The term “cloud” was coined from the computer network diagrams which use it to hide the complexity of infrastructure involved. cloud computing provides software, platform and infrastructure as a service. its main features include resource pooling, rapid elasticity, measured service, on-demand self service and broad network access. so, a cloud is a collection of hardware and software that runs in a data centre and enables the cloud computing model. A cloud reduces capital investment, hardware cost and software licence cost.
The previous chapter demonstrated the key fundamentals of the research and an introduction to the concept of Cloud Computing. Even though a lot of research work has been done on the subject of cloud computing, the field is still a relatively new academic field. The National Institute of standards has established the standards related to Cloud computing and the research into the subject continues, especially with new tools and technology infrastructure that continues to evolve at a very fast pace.
Cloud computing allows a group of services and networks which work together to provide storage and information. Cloud computing means resource offered as a rental over the Internet instead of storing information on your own drive you can directly use it on the Internet without downloading it.
