The industries use cloud computing for various purposes. Demand Set to Outpace Enterprise Application Software Market The article describes reference architecture and criteria for the classification of EAI systems, which are derived from different integration approaches. Cloud-based services have turned out to be pervasive to the point that, for some associations, it's hard to envision utilizing applications and innovation foundation components without the cloud. Private Cloud - A private cloud is established for a specific group or organization and limits access to just that group. This is because cloud computing is made for collaboration and … “Business Process Management” is one of the major themes within enterprise information systems and “Designing Enterprise Information Systems” discusses new approaches to the design of processes and system and also deals with how design can be taken as a specific perspective. •NIST Definition of Cloud Computing "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction." This paper begins with defining cloud computing, its key characteristics, deployment, service models, benefits and challenges. Research firm IDC thinks that cloud computing will reach $42 billion in 2012. Perhaps it must be the first priority to protect data depositories. 3. This is a good move as it offers IT-based solutions that are optimal for use and other crucial services essential in the operations of the IT industry. Many organizations have started offering cloud based solutions to their customers which has made security a major aim in their projects. I/O virtualization bottlenecks in cloud computing today FREE DOWNLOAD [PDF] J Shafer ,Proceedings of the 2nd conference on I/O , 2010 ,li46-224.members.linode.com ABSTRACT Cloud computing is gaining popularity as a way to virtualize the datacenter and increase flexibility in the use of computation resources. The optimization of resource utilization may be carried out either in discrete time or in continuous time.

Cloud users need not to take care about the hardware and software they use and also they don’t have to be worried about maintenance. We extend this approach further by using a two-phase heuristic that allows the decision making component to scale up to handle large scale grid systems. Cloud Computing is a versatile technology that can support a broad-spectrum of applications. Cloud computing services are a growing necessity for business organizations as well as for educational institutions. There is no doubt that it has taken the computer society by a storm in recent years. Private Cloud Computing. A public cloud is the type of cloud that you see big companies (like Microsoft) advertising on TV. Cloud computing does not exist in a vacuum. This paper is basically about data security techniques and challenges and how you can protect the cloud. Cloud computing in particular seems to be setting the agenda for future research in enterprise information systems. Experimental result illustrated that having a fuzzified firewall gives high point-to-point packet utilization decreasing the response time than a conventional firewall. More people are getting aware of the technology which is making it easier for them to break into different clouds and retrieve their desired information. Even though security is getting better day by day but still hackers are finding ways to exploit a particular cloud. The cloud is used by health care companies to develop personalized Health treatments. %%EOF In this paper, we consider several types of basic services and show how their orchestration may lead to the provisioning of more sophisticated services. This means the device accessing the cloud doesn't need to work as hard. Abstract—Cloud Computing provides functionality for managing information data in a distributed, ubiquitous and pervasive manner supporting several platforms, systems and applications. Section 2 and Section 3 is about the different deployment and service models in cloud computing. Cloud computing can also offer pre-built solutions and services, backed by the skills necessary to run and maintain them, potentially lowering risk and removing the need for the organization to retain a group of scarce highly-skilled staff. Section 4 is about the security risks to data in cloud. 4. This paper explores security challenges faced by cloud computing. It is growing really fast in the field of computer science. Basically, such business models consider the problem of computing, storage and network resources virtualization. Although there are still several risks and challenges are associated with cloud but its potential benefits outweigh the risks. While cloud computing is a foundation for digital business, Gartner estimates that less than one-third of enterprises have a documented cloud strategy. High speed Internet access and multi-core Virtual Machines (VMs) enable today the provisioning of diversified and enriched types of services in Cloud environment. The cloud service providers must insure the protection of contents from various malware and for that there are different policies and mechanisms of Cloud service providers. It is getting implemented in many organizations very fast. However, before you can decide on a cloud model, you need to determine what the ideal cloud service model is for your business. Architecting the Cloud is vendor neutral and guides you in making one of the most critical technology decisions that you will … Delegating all data to the edge is also not a wise decision. Cloud itself consists of physical machines in the data centers of cloud providers. In this paper, we describe efficient strategies for policy-based controlling of virtualization of the physical resources. Gartner RAS Core Research Note, 3 August 2007 Moxie Resolving the stress. Cloud deployed enterprise resource planning (ERP), supply chain management applications (SCM), customer relationship management (CRM) applications, medical applications and mobile applications have potential to reach millions of users. First, there is public cloud and private cloud. In “Concepts in Enterprise Information Systems” the authors present new concepts and ideas for the field. It uses the internet, remote central servers to maintain data & applications. from public cloud computing. Start by thinking about the different modes, or IT approaches, of your business. © 2008-2020 ResearchGate GmbH. Cloud Computing is gaining so much popularity an demand in the market. In conclusion, cloud computing is recently new technological development that has the potential to have a great impact on the world. In this way, consumers are billed for services according to how much they have actually used during the billing period. Leveraging our experiences on various clouds, we examine clouds from technical, and service aspects. You get purely what you need, when you need it. Instead, you can provision exactly the right type and size of computing resources you need to power your newest bright idea or operate your IT department. The low cost of cloud computing and its dynamic scaling renders it an innovation driver for small companies, particularly in the developing world. Internal users may or may not be billed for services through IT chargeback. Cloud computing gives Shared pool of assets (computers resources like networks, server and storage) on the demand of the user in ubiquitous and in simple word provides usability to the end customer maintaining minimum cost for their usage. 2. integrate these packaged software applications with each other as well as with existing or legacy business applications drives the need for standardized integration architecture to more flexibly implement new business processes across different organizations and applications. According to the Cloud Security Alliance, 79% companies receive regular requests from users to buy more cloud applications with file sharing and collaboration being one of the top-requested cloud services. “Cloud computing will become the dominant design style for new applications and for refactoring a large number of existing applications over the next 10-plus years,” said Donna Scott , vice president and distinguished analyst at Gartner. We can protect our data from unwanted access on a hybrid cloud through controlling the respective firewall of the network. Cloud computing is a technology that puts your entire computing infrastructure in both hardware and software applications online. After a particular has deployed his/her cloud based platform, the biggest fear is its security. Through virtualization, Cloud computing is able to address with the same physical infrastructure a large client base with different computational needs . Cloud computing is one of the highly flexible, confidential and easily accessible medium of platforms and provides powerful service for sharing information over the Internet.
