Cloud Computing

Cloud computing is a one of the most talked of topics in the field of Information Technology in recent times (Keyun, Joe, Taha, & Ibrahim, 2013). This subject area of cloud computing basically is a term used to describe computer resources available as a service accessible over a network (Darren & Kim-Kwang, 2013). The National Institute of Standards and Technology (NIST) define cloud computing as a model for enabling ubiquitous, convenient, on-demand network access on 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 (Peter & Timothy, 2011). Due to the attractive nature of the model there has been rise in the use of cloud computing. Gartner, an IT research and consulting firm, says that cloud computing is growing will become the bulk of IT spend by 2016 (Gartner, 2013).

To overcome the above issues, use a hybrid cloud infrastructure [2]. It combines public cloud, private cloud and dedicated servers (Figure 1), which works in one platform. It satisfies the purpose of different businesses.

Cloud computing has advanced as of late. The new universe of the hybrid cloud is a situation that utilizes both private and public cloud administrations. Organizations understand that they require a wide range of sorts of cloud benefits with a specific end goal to meet an assortment of client needs.

Furthermore, different deployment models exist, we are going to focus only on the two different poles, the private cloud and the public cloud. The former means that the cloud infrastructure is owned and operated by a single and usually the same organization, while the latter stands for a public infrastructure where basically everyone can use it under different conditions. And this is the “cloud” we will be referring to in this essay.

The advantages of cloud computing include cost savings, meeting computing needs, reliability, and centralized security functions. This will lead to overall lower costs, improved information handling, and greater convenience for end users. All of these advantages make cloud computing worth considering.

A hybrid Cloud Deployment model with a combination of Public, Private and Community models will be used. The Cloud Service Delivery model will be a combination of SaaS, PaaS and IaaS to satisfy the requirements of the multiple business units within the organization, customers, and suppliers resulting in a cost reduction through optimized and efficient computing

Disaster Readiness and avoidance: The hybrid cloud approach can provide the public cloud as a disaster recovery site to create and bring up workload in case of failure.

The difference between distributed computing with individualized computing is that the cloud technology gives an extensive variety of capacities. The usage of cloud built solutions depends on different elements, for example, the division in which the business works; the practicality of porting existing parts on cloud, size of the organization, and the area of customers and so on. It helps in reducing the time required as well as minimize the fixed cost of the company. Therefore, it is not logistic to make a single explanation of implementation of cloud computing technology. For example, a newly started company can adopt the cloud based solution easily but it is difficult for existing firms to shift their supply chain to cloud technology. Let consider a business has both ERP and CRM solutions, as concern from security view the business may move their CRM to cloud while store ERP in house server.

Hybrid clouds are combinations of public and private clouds that work together. In this model, IT typically outsources noncritical information and processing to the public cloud, while keeping business critical services and data in their control. The hybrid cloud environment works to seamlessly integrate external applications on other private and public clouds, with your in-house processes. The major drawback to the hybrid cloud is the difficulty in effectively creating and governing such a solution. Services from different sources must be obtained and provisioned as if they originated from a single location, and interactions between private and public components can make the implementation even more complicated. These

Cloud based computing can be considered as an upcoming computing paradigm or a business model allowing organizations and businesses to Incorporate IT capabilities without having to Invest heavily upfront to set up the IT infrastructure. It is incontrovertible that the capabilities and the advantages provided by cloud based services can greatly benefit businesses and organizations around the globe, but there remain some unresolved issues with respect to cloud based systems that can hinder

Hybrid cloud computing refers to policy-based and coordinated service provisioning, use and management (orchestration) across a mixture of private and public cloud services. Gartner has predicted that by 2019, more than 30 percent of the 100 largest vendors’ new software investments will have shifted from cloud-first to cloud-only. They have also predicted that 90% of organizations will adopt hybrid infrastructure management by 2020. Developing a solid hybrid cloud strategy can help address issues including:

Cloud BI is an integration of two technologies: Cloud Computing and Business Intelligence. The main aim of this integration is to provide cloud-computing features to Business Intelligence. Cloud BI has matured into an articulate resource and a well-defined structure. The Cloud BI systems are flexible, scalable, easier and faster to deploy than any other systems. As an issue, bigger and obscure information sets can be collected and also transformed into a jaw-dropping show of crude advanced inputs from about every interior and outside part of business. Everyone in your organization can have admittance to information they can get to business on, modify and share. Cloud BI is all the more about simplicity of sending, utilization and administration. While Cloud BI can be facilitated and oversaw by a merchant, it can likewise be conveyed on a private Cloud foundation like Amazon or Microsoft Azure. With the headway of cloud foundation innovations like Openstack, conveying and overseeing private cloud base is getting to be simpler for some ventures. As an issue, whether Cloud BI is sent on a multi/single-inhabitant environment on seller base, an outsider cloud framework like Amazon, Azure, and so forth or on inside private cloud, it gets to be to a greater degree a business choice instead of a specialized restriction.

Business applications have dependably been excessively extravagant. They oblige a datacenter which offers which offers space, power, cooling, bandwidth, networks, entangled programming stack and servers and storage and a team of experts to install, configure and run them. We need development, staging, testing, production and failure environments and when another adaptation comes up, we need to upgrade and then the entire framework is down.

Banks are facing increased pressure to streamline their current processes and trim operating costs, while also responding to more demanding, digitally connected customers (Adams, 2012). Many banks are even looking at new technologies and IT delivery models such as cloud computing to help address these issues. Banks have many reasons to like the cloud, such as cost efficiency, standardization and consistency (Dragon, 2013). Banks are embracing the cloud more and more because it allows them to be more quick and responsive to the ever changing customer demands and designing new revenue-generating opportunities.

The main trends within cloud computing are hybrid clouds, BYOD (Bring your own device), PaaS (Platform as a service), big data analytics, graphics as a server, identity management and protection and web powered apps. Hybrid clouds are an infrastructure that combines high levels of private security and cost-effectiveness with public cloud attributes. Customers can get better personalisation of their
