Cloud Computing Deployment Model For Cloud Services Essay

Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.

Cloud computing has set a trend in the information technology arena that has sparked the interest of all who utilize the internet on purpose and unsuspectingly. Initially, the primary purpose of cloud computing was to provide a centralized data bank that organizations could use for quick data access. Its use has been quickly adapted, however, beyond business use to become the first option for personal use. The advantages and disadvantages of implementing such a shift from business to personal are varied, yet, statistically, according to the CISCO Global Cloud Index: Forecast and Methodology, 2014-2019 White Paper, its public use is on the rise. The report notes that “by 2019, 56 percent of the cloud workloads will be in public cloud data centers, up from 30 percent in 2014 and by 2019, 44 percent of the cloud workloads will be in private cloud data centers, down from 70 percent in 2014”. Though disadvantages with regard to data security is prominent, users have deemed that its implementation will still promote greater benefits than loss.

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

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.

Kareo is a cloud based platform that includes electronic health records (EHR), patient management, and medical billing. This software would be ideal for smaller practices as it helps to easily stay connected with patients with an in app messenger system that allows therapists and patients to speak to one another. It also helps with appointment scheduling that sets alerts and reminders to avoid no show appointments and improve wait times. It can also check the eligibility of patients for insurance in real time through its electronic connections with a large number of insurance companies.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

Recent technological advancements have resulted in an increased number of Internet-enabled devices, such as tablets and smartphones that can connect to corporate systems.These systems may also be running anywhere, including a public software-as-a-service (SaaS) cloud, a

(3) Web Services in the Cloud - instead of delivering full applications, this service allows users to access APIs for added functionality.

Cloud computing is revolutionizing the use software globally at a very rapid pace as it is completely redefining the economics of how software is purchased and used. Web 2.0 technologies and their underlying design precepts are responsible for the current and future generations of social networks (Bernoff, Li, 2008). Both have immediate and significant impacts on the operations of businesses and the major contributions each makes are explained in this analysis.

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

Connecting to a public cloud can offer a conduit into your private environment. Any data transferred across a network is subject to third-party eavesdropping and interference, so it must be protected. Nevertheless, it’s not unusual for an organization to discover that a public cloud service has a more robust security strategy than what they have in-house. A hybrid solution requires a thorough review of all your current security precautions and a carefully planned strategy for moving into the hybrid cloud.

With the creation of cloud computing it has made private businesses able to implement fast adaptations and changes to the computing environment that they are using. However, in the larger public sector, issues of security tend to hold back these companies not allowing them to adopt

The surge in advancements in distributed systems and networking technology and the advantages that it has brought along with it, has many individuals and organizations move from local to remote cloud storage [1]. Cloud storage falls under Infrastructure as a Service (IaaS) in the series of cloud services where in, a user’s or organization’s data is stored in a nexus of remote servers. Cloud infrastructures can be broadly classified as either public or private. The remote servers provided by public cloud storage service, preserves the unhindered and efficient accessibility of a local storage server along with transparency while customers/users has access to their data. While there are benefits to using a public cloud infrastructure, it poses significant privacy and security risks [2]. The goal of this research is to obtain the degree of security that is indigenous to a private cloud environment in a public cloud environment with respect to data storage. To achieve such degree of security [1], a public cloud storage service should provide (at least):

The public cloud offers unlimited potential for scaling business. On-demand compute and storage are only a small portion of the benefits of a highly agile IT environment. Easy access to applications, services and development environments promises to redefine business agility. Naturally, more and more organizations are taking critical workloads to the public cloud. Still the migration to an environment that is provisioned and managed by a non-organizational stakeholder creates new security challenges.
