The 4 Primary Cloud Deployment Models

- Recommended by the National Institute of Standards and Technology (NIST) * Cloud used for capital expenditure and control operating costs, and business cloud adoption * Can come from security risks and challenges and possibly costly for IT Management

The Private Cloud
- tremendous value in terms of security * hosting is built and maintained for a specific client * infrastructure required for hosting can be on-premises or at a third-party location * Security from using a secure-access VPN / physical location within the client’s firewall system * considering downtime, internet availability, quality and performance of mission-critical applications is necessary hence, hosting the application with an on-premises private cloud is the suggested approach * Interoperability: Data and applications that have to conform to various regulations/standards/countries * No cost benefit; comparable to buying, building and managing your own infrastructure.

The Public Cloud * true cloud hosting * services and infrastructure are provided to various clients * provided by a vendor free of charge or on the basis of a pay-per-user license policy * reduces capital expenditure * reduces operational IT costs * can manage load spikes * host SaaS applications * can utilize interim infrastructure for developing and testing applications * manages applications which are consumed by many users that would otherwise require large investment in infrastructure from businesses

The Hybrid Cloud * helps businesses to take advantage of secured applications and data hosting on a private cloud (Many PaaS deployments expose their APIs and need this structure) * cost benefits by keeping shared data and applications on the public cloud *

...OCM 1.6 - Deployment of an EC Site By Anusha Avutapalli Deployment may refer to: •Deployment flowchart, a process mapping tool used to articulate the steps and stakeholders of a given process . •System deployment, transforming a mechanical, electrical, or computer system from a packaged form to an operational state. •Software deployment, all of the activities that make a software system available for use. Deployment flowchart A deployment flowchart (sometimes referred to as a "cross functional flowchart") is a business process mapping tool used to articulate the steps and stakeholders of a given process. "Deployment flowcharts consist of a sequence of activity steps and also the interactions between individuals or groups." Each participant in the process is displayed on the map (which is constructed as a matrix) - tasks/activity are then articulated in sequence under the column corresponding to that stakeholder. As deployment flowcharts highlight the relationships between stakeholders in addition to the process flow they are especially useful in highlighting areas of inefficiency, duplication or unnecessary processing. Often utilized within Six sigma activity, completed flowcharts are commonly used to examine the interfaces between “participants” which are typically causes for delays and other associated issues. Deployment flowcharts are useful for determining who within an organization is required to implement a process and...

...Quality Function Deployment of Custom Orientation Stabilization Integrated Systems September 23, 2012 Scott Jaster ENM5100 Quality Engineering Florida Institute of Technology ABSTRACT The purpose of this paper is to present a description of the Quality Function Deployment (QFD) process with respect to the development of an alternative means of multi-axis orientation stabilization. The intention is to discuss the quality control process of choosing the "best" components for the system, and meeting customer requirements before, during, and after product delivery. There will be an exploration of the Quality Function Deployment (QFD) process that pertains to the systems integration design, manufacture, and delivery process, from the user’s ultimate perspective. The interactions of the various components must be defined by the desired specifications, modeled, and analyzed to produce the optimal setup that meets the respective performance requirements of the user, while following along with the QFD process strategy. The focus will be on the House Of Quality (HOQ), described within. A related discussion will be the determination of the viability and functionality of designing a system capable of efficiently counteracting axial orientation wobbling; but this is the byproduct of the properly employed functional Quality process. Ultimately, the discussed Quality process allows the user to efficiently and subjectively determine the best engineering trade-offs related...

House of Quality

...Service Operation Management Ashim Abhinav Ekka Assignment 14133 HOUSE OF QUALITY House of Quality is a diagram, resembling a house used for defining the relationship between customer desires and the firm/product capabilities. It is a part of the Quality Function Deployment (QFD) and it utilizes a planning matrix to relate what the customer wants to how a firm (that produces the products) is going to meet those wants. It looks like a House with a "correlation matrix" as its roof, customer wants versus product features as the main part, competitor evaluation as the porch etc. It is based on "the belief that products should be designed to reflect customers' desires and tastes”. It also is reported to increase cross functional integration within organizations using it, especially between marketing, engineering and manufacturing. QFD is a tool for translating customer requirements into company requirements and identifying features or capabilities required to become a best-in-class provider. Today, customers are demanding ever-more-challenging levels of quality. A customer lost due to poor quality may never return, and, even worse, may take several potential customers with it. For electronics manufacturing, in which M&As are routine and capital investment is increasing, a reasonable return on investment can be achieved only by being a superior supplier. One must understand the difference between value and price. With competition growing...

...parameters or characteristics, which vary from product to product. For example, for a mechanical or electronic product these are performance, reliability, safety and appearance. For pharmaceutical products, parameters such as physical and chemical characteristics, medicinal effect, toxicity, taste and shelf life may be important. For a food product they will include taste, nutritional properties, texture, and shelf life and so on. "Time was when a man could order a pair of shoes directly from the cobbler. By measuring the foot himself and personally handling all aspects of manufacturing, the cobbler could assure the customer would be satisfied," lamented Dr. Yoji Akao, one of the founders of QFD, in his private lectures. Quality Function Deployment (QFD) was developed to bring this personal interface to modern manufacturing and business. In today's industrial society, where the growing distance between producers and users is a concern, QFD links the needs of the customer (end user) with design, development, engineering, manufacturing, and service functions. QFD is: 1. Understanding Customer Requirements 2. Quality Systems Thinking + Psychology + Knowledge/Epistemology 3. Maximizing Positive Quality That Adds Value 4.

...Quality function deployment Quality function deployment (QFD) is a “method to transform user demands into design quality, to deploy the functions forming quality, and to deploy methods for achieving the design quality into subsystems and component parts, and ultimately to specific elements of the manufacturing process.”,as described by Dr. Yoji Akao, who originally developed QFD in Japan in 1966, when the author combined his work in quality assurance and quality control points with function deployment used in value engineering. QFD is designed to help planners focus on characteristics of a new or existing product or service from the viewpoints of market segments, company, or technology-development needs. The technique yields charts and matrices. QFD helps transform customer needs (the voice of the customer [VOC]) into engineering characteristics (and appropriate test methods) for a product or service, prioritizing each product or service characteristic while simultaneously setting development targets for product or service. Areas of application QFD is applied in a wide variety of services, consumer products, military needs , and emerging technology products. The technique is also used to identify and document competitive marketing strategies and tactics (see example QFD House of Quality for Enterprise Product Development, at right). QFD is considered a key practice of Design for Six Sigma (DFSS - as seen in the referenced roadmap). It is also included in the new ISO 9000:2000...
