Project Analysis : Cloud Architectures

International Journal of Cloud Computing: Peer-reviewed open access journal, it publishes research crossing all aspects of Cloud Computing. Basically centered around center components, including Cloud applications, Cloud systems and the advances that will prompt the Clouds without bounds, the journal will likewise show review and survey papers that present new bits of knowledge and establish the frameworks for encouraging exploratory and experimental work. The journal disseminates research that imparts progressed hypothetical establishing and functional application of Clouds and related systems, as empowered by mixes of web-based programming, advancement stacks and database availability and virtualized equipment for storing, handling, analysis and visualizing data. A scope will look at Clouds nearby such different standards as Peer to Peer (P2P) figuring, Cluster processing and Grid registering. Scope reaches out to issues of administration, governance, trust and

Amazon Web Services (AWS) delivers reliable, scalable, and cost-effective computing resources on which to host applications. You can use the following AWS components alone or combined to host application(s) Amazon Elastic Compute Cloud (Amazon EC2). Amazon EC2 provides resizable compute capacity in the cloud. You define the virtual Amazon EC2 environment with the operating system, services, databases, and application platform stack required for Apparel Brands hosted application. Amazon EC2 provides a full management console and APIs to manage your computer resources.

The focus of cloud computing is providing with scalable and a cheap on-demand computing infrastructure with a good quality of service levels. The process of the cloud computing involves a set of network enabled services that can be accessed in a simple and general way. Cloud computing provides with a unique value proposition for any organization to outsource their information and communication technology infrastructure. Moreover, the concept itself provides with a value proposition for an organization as using the cloud saves on cost, resources, and staff, and business opportunities for the organization (Katzan). An extensive connectivity of

Amazon Web Services is a cloud computing platform which was to provide online services to websites (Rouse, 2014). Amazon is comprised of software development and customer service centers around the world (Rouse, 2014). At Amazon, workers are encouraged to tear apart one another’s ideas in meetings, toil long and late and held to unreasonably high standards (Kantor & Streitfeld, 2015).

Every application in Amazon has a number of dependencies. To ensure the application provides its complete functionality, the dependencies of the application must be executed within a smaller and stringent time. To ensure this, the client engages in a contract with services called as the Service Level Agreement (SLA). SLA can be defined as “a

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]:

Amazon business started in 1994 as an e-commerce merchant, and while expanding its abilities as the leading online retailer, Amazon recognized, orchestrated, and launched new dynamic capabilities in cloud computing by 2006. This paper will analyze the drivers behind Amazon’s vision and decision to complement its core business model to incorporate a novelty, which was outside the retail industry. In addition, discuss Amazon’s strategy to deliver web services that are reliable, scalable, simple to use, quick to start, and cost effective. Furthermore, besides technology,

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

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

Amazon Web Services (AWS),is an on-demandcomputing platform. .Amazon Web Services’ cloud philosophy, increasingly driven by a belief in building architecture that is cost-aware and designed to optimize economies of scale so it can do volume transactions at thin margins.It enable businesses and developers to use web services to build scalable, sophisticated applications.Amazon Web Services provides a highly reliable, scalable, low-cost infrastructure platform in the cloud.

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

Amazon’s core business of selling goods (ranging from books to fresh food and electronics to fashion cloths) through its e-commerce portal has seen exponential growth which necessitated a need for a massive storage and computing infrastructure that is always available and is resistant to failures. After building this, it is intuitive for Amazon to open up the infrastructure and sell it as a commodity. This helps Amazon not only to attract more customers to this new product but also to build new infrastructure thus benefiting its core business.

It is said that one-third of all Internet users visit a site or application powered by Amazon Web Service. As a developer leveraging the AWS, I had my fair share of questions. How secure is my critical data? Is the system fault-tolerant? How much control do I have over the infrastructure? How do the people in Amazon overcome the technical challenge of maintaining such a massive infrastructure? These questions kindled my curiosity in Cloud Computing. This curiosity has led me from hosting a static website in S3 for fun, to working on creating full-scale dynamic web applications that cater to thousands of scientists on a daily basis. I have a passion for developing software applications and using them as a tool to serve people. It is with
