Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access
Cloud computing is nothing but rate server and internet based model .A huge amount of data being retrieved from geographically distributed data sources and non localized data handling requirements. The industrial information technology towards a subscription based or pay-per-use service business model known as cloud computing. One of the advantage of cloud computing is cloud data storage, in which users do not have to store his own data on their own server...
According to the National Institute of Standards and Technology (NIST), cloud computing is referred to as a model for enabling convenient, on-demand network access to a shared pool of configuration computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. The following paper will discuss the meaning of cloud computing, the major providers, benefits of adoption, pitfalls of adoption, current trends in the business community, and current application within the business community.
Cloud computing is a buzzword which has cropped up recently in the last 3-4 years. The term refers to computing where lots of distributed computers exchange data and information over the internet. The term is used synonymously with internet now a day. Now cloud computing is being used in all types of business including small, large and medium businesses. Gartner is predicting that SAAS market will grow at a CAGR of 16% through 2013 in Small and Medium Business segment. A typical cloud technology has the following features:
Due to the rise in popularity of virtualization technology and faster transmission speeds with higher bandwidth, cloud computing has advanced to the forefront of today's cutting edge technology. Organizations are continuing to look for ways to provide efficient and reliable storage availability for organizational assets and agility to change requirements quickly in alignment with national and global business strategies. According to Gartner, “cloud computing revenue for cloud services will approach 152.1 billion...
Computer is a device that can be programmed to do some task desired by the programmer. Computer can do several tasks by doing some sets of arithmetic and logical operations. With those capabilities, computer can help human to solve many problems in their life. Nowadays, human life can not be separated from the role of computer. Almost of all human’s activities involving computers. From getting up in the morning until going to the bed in the night, human always keep in touch with computer. All the technology today is based on computer system. From the little thing such as watch until the big thing such as skyscapers, even NASA spaceships use computer system to run. Many computers today still use the ‘traditional’ form. The traditional form of computer means the computing resources, like hardware or software is reside on client side. It means you have to serve hardware like CPU,RAM, or hardisk and software such as operating system (windows, Mac os, or Linux) to run a computer. This traditional form computer still can we see in many places such as people’s house, schools, public spaces, or companies. This time, there is a newer computing system called cloud computing. Like its name, this cloud computing use the computing resources on the ‘cloud’. This cloud means the computing resources (hardware or software) is placed far away from the client side. This computing resource is connected with client/user over a network such as internet. The cloud computing offers several number of benefits than the traditional computing such as its cost efficiency, environmentally friendly, data back up and recovery, and the ease of access.
Once you login to your computer you are bound to use an application that is related to the cloud computing infrastructure. For example, when any service needs an internet connection it immediately uses what is known as a “cloud” network, which is a broad term for the use of a device or application that is not physically present. The computer user is then accessing a network in the cloud, which stores personal information and allows for multiple tasks to be completed in an efficient manner rather than just using a single personal computer. Computer Scientists do find an importance for expanding the cloud network since it not only helps them create projects using multiple computers linked on the cloud but it also helps deliver applications to any computer user. Unfortunately, there are some deficiencies that computer science majors should be aware of; the biggest default the risk of cloud security issues constantly. These issues include vulnerability to data loss and hackers overtaking the system; computer scientists should be aware of the structure’s defaults and be able to use cloud services efficiently. Cloud computing is a highly useful and quickly growing aspect of technology, and although the security issues are a risk, it is a useful service that should be used with the proper prior knowledge.
Cloud computing is something users do every day, which is using the browser to access resources from servers on a network. The cloud combines hardware, networks, storage, and even infrastructure to offer services available with just an internet connection. One key feature of cloud computing is the elasticity provided for a network. A network that is utilizing a cloud service will have the network monitored for usage and when a spike of resource use is indicated the necessary resources will be provided to the network, providing a smooth transition that would not be noticeable. This makes the network not suffer from more users or even adding new resources. Having this resource provisioning also reduces cost because the network is not using too much and not needing it or having to upgrade and add hardware to increase the resources.
In the 1950s Cloud computing started with mainframe computing, where multiple users were able to access a central computer by using a dumb terminal, which had only one function, and that was to provide access to the mainframe. In the 1970s, the concept of virtual machines was created, by using the virtual machine technology it was possible to used more than one operating system simultaneously in a secluded environment. In 1993 cloud computing reached its first milestone with e-mail, which is a method of exchanging information/ data or digital messages through a computer network of the internet. Emails were originally a text based form of communication only, these days’ files like multimedia, images or PDFs can be attached. Today, cloud computing is a part of our everyday lives, we still use it to email, and now we use a more perfected cloud system to store applications or files and can access them anywhere and anytime.
Cloud computing Application revolves around the services that have been used in an enterprise through internet. The user often have little knowledge about the services but still he or she is able uses it wisely. Customers now routinely utilize information escalated provisions determined by cloud engineering which were awhile ago occupied because of expense and sending multifaceted nature. In numerous organizations workers and organization offices are bringing a surge of shopper innovation into the working environment and this raises lawful agree ability and security attentiveness toward the enterprise.
