The Success Story Behind Ericsson's Reliable Cloud Platform

The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “a model for enabling ubiquitous, 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”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology

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 moving into the mainstream. Moving to the cloud might be a viable option for some consumers. However, there are many facets to consider before moving to the cloud. There are four types of clouds, public, private, community, and hybrid. All four cloud arrangements have pros and cons, and they need to be weighed before a decision is made. Two main challenges of clouds are security and privacy. These two main issues must be addressed prior to choosing a cloud service. As a consumer, you make the choice for how stringent your security and privacy are to your stakeholders.

Cloud Computing is a style of computing in a scalable and elastic IT-related capabilities are offered ‘as a service to customers using internet technologies’. This case study will clarify Ericsson benefited from Amazon Web Services in term of cost reduction, automated software updates, remote access, and on-demand availability. It will evaluate the scalability, dependability, manageability, and adaptability of Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Services (Amazon S3), and RightScale. It will observe the security concerns for cloud-based services and make suggestions to cope with these concerns. It will assess possible scalability, reliability, and cost issues associated with cloud computing, and make suggestions

Cloud computing is a novel tool that provides an opportunity for large or small business owners based on an entirely new business model. The term cloud computing itself is a familiar term, however, the specific meaning can be difficult to define. This paper discusses several facets of cloud computing topics to include cloud benefits, characteristics, as well as service models.

Cloud computing refers to the delivery of computing services over the internet. The computing services include: infrastructure, development platforms and software applications. Cloud services are privately owned for the purpose of remotely provisioning scalable and measured IT resources from data centers located around the world.

Cloud computing is internet-based computing in which large collections of isolated servers are interacted to allow the centralized data loading, and online access to computer services or resources. Clouds can be classified as public, private or hybrid (National Institute of Standards and Technology, 2011).

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 an evolving term that describes the event of the many existing technologies and approaches to computing into one thing totally different. Cloud separates application and therefore the resources with info from the underlying infrastructure, and therefore the mechanisms wont to deliver them. Cloud enhances collaboration, agility, scaling, and availableness that provides the potential for price reduction through reduced and economical computing. The word Cloud describes the employment of assortment of services, info, infrastructure comprised of pools of network, info, and storage resources. These elements are often quickly organized, provisioned, enforced and decommissioned, and

The term cloud computing encompasses allot of areas of technology. It also includes new ventures such as hardware service, a way to manage storage and server load on demand from Amazon and others. What all these cloud computing services do in common, though, is that they are all delivered over the Internet from massive data centers (Kroenke, 2013, King, 2008, Wardley, 2012, Hinchcliffe, 2014).

Cloud computing is the idea where application runs on a remote server that is provided as a commercial service by a company rather than an institution or individual’s local machine. Cloud computing has made possible to provided Software as a Service, Platform as a Service and Infrastructure as a Service (Beaty, 2013,p. 88-93)

Cloud computing programs, or the ideas of them, have been around since the 1960s, but it was not until the 1990s that the services were finally available due to advancements in technology. But to fully understand the importance of this innovation we must define what cloud computing is. Per the National Institute of Standards and Technology, an agency that creates standards and guidelines for providing information security for all agency operations and assets has defined cloud computing as a model that have easy access to a pool of shared network. Cloud computing programs must have the following five characteristics to be defined as such: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. Once the program satisfies these five elements in can meet one of three service models: Software as a Service, Platform as a service, and Infrastructure as a Service and one of four development models: private cloud, community cloud, public cloud, and hybrid cloud. For the sake of this paper we will focus on Software as a Service (Grance, 2011, 2-3).

Anything that involves delivering hosted services over the Internet is Cloud computing. Cloud computing is a type of Internet-based computing where different services -- such as servers, storage and applications – are delivered to an organization's computers and devices through the Internet. cloud computing structure allows access to information as long as an electronic device has access to the web. Cloud computing system allows employees to work remotely. Examples of cloud computing include social networking websites and facebook.

The use of cloud technology has become increasingly mainstream as individuals and businesses adapt to an environment in which having access to information and services 24/7, on a computer, phone or tablet is normal the new norm. Convenience, efficiency and data protection

Cloud computing is Internet based computing wherein the virtual shared servers provide infrastructure, platform and various resources including customer hosting as a service on pay-as you-use basis. Figure
