LESSON 1 ARCHITECTURAL CONCEPTS- C838 |86 QUESTIONS WITH 100% CORRECT ANSWERS.

If a service or solution does not meet all of the specified key characteristics listed below, it is said to be not true cloud computing. Please select the valid cloud computing characteristics out of the terms identified below. Each correct answer represents a complete solution. Choose all that apply. resource pooling broad network access measured system selected self-service on-demand self-service measured service resource pooling broad network access on-demand self-service measured service Which of the following requirements consider performance aspects of a device, process, or employee that are necessary for the business task to be accomplished? non-functional requirements functional requirements organizational requirements connectivity requirements functional requirements In which of the following ways can organization use hosted cloud services to augment internal, private data center capabilities with managed services during times of increased demand? cloud monitoring cloud bursting cloud retrieving cloud hosting cloud bursting Which method is used to gather business requirements? interviewing project managers interviewing functional managers calculating personnel costs collecting computational cost interviewing functional managers Those performance aspects of a device, process, or employee that are necessary for the business task to be accomplished. Example: A salesperson in the field must be able to connect to the organization's network remotely. Functional requirements Those aspects of a device, process, or employee that are not necessary for accomplishing a business task but are desired or expected. Example: The salesperson's remote connection must be secure. Nonfunctional requirements Interviewing functional managers Interviewing users Interviewing senior management Surveying customers Collecting network traffic Inventorying assets Collecting financial records Collecting insurance records Marketing data collection Collecting regulatory mandates Possible methods for gathering business requirements an assessment of the priorities given to each asset and process within the organization. BIA things like routers and servers tangible assets patents, trademarks, copyrights, and business methodologies. intangible assets This is the flexibility of allocating resources as needed for immediate usage, instead of purchasing resources according to other variables. elasticity Usage and administration of cloud services ought to be transparent to cloud customers and users; from their perspective, a digital data service is paid for and can be used, with very little additional input other than what is necessary to perform their duties. Proper cloud implementations should not require constant or even frequent interaction between the cloud provider and cloud customer. Simplicity The organization's computing needs won't remain static: there will be new (and hopefully more) users, customers, and data as the organization continually matures. A cloud service can easily meet those needs, either temporarily or long-term, in a much more cost-efficient manner than a traditional environment, because new computing resources can be assigned and allocated without any significant additional capital investment on the part of the cloud provider, and at an incremental cost to the cloud customer. scalability anyone who is purchasing a cloud service (which could be an individual or a company) cloud customer is just someone using cloud services cloud user IaaS Infrastructure as a Service PaaS Platform as a Service SaaS Software as a Service consists of applications, CRM, hosted HR and email SaaS Includes everything listed in the previous Infrastructure as a service (IaaS) and Platform as a service (PaaS) models, with the addition of software programs SaaS consists of operating systems such as Windows, Linux, Unix, etc. PaaS consists of hardware, blades, connectivity, and utilities IaaS allows the customer to install all software, including operating systems (OSs) on hardware housed and connected by the cloud vendor. IaaS contains everything included in IaaS, with the addition of OSs. This model is especially useful for software development operations (DevOps). PaaS The resources (hardware, software, facilities, and staff) are owned and operated by a vendor and sold, leased, or rented to anyone public cloud Examples of vendors include Rackspace, Microsoft's Azure, and Amazon Web Services (AWS). public cloud owned and operated by independent organizations, for the exclusive use of their customers and users. private cloud features infrastructure and processing owned and operated by an affinity group; disparate pieces might be owned or controlled by individuals or distinct organizations, but they come together in some fashion to perform joint tasks and functions. community cloud contains elements of the other cloud models. hybrid The vendor offering cloud services. CSP The organization purchasing, leasing, or renting cloud services. cloud customer third-party entity offering independent identity and access management (IAM) services to CSPs and cloud customers, often as an intermediary. This can take the form of a variety of services, including single sign-on, certificate management, and cryptographic key escrow. CASB The entities that ensure organizations are in compliance with the regulatory framework for which they're responsible. regulators An open source cloud computing and IaaS platform developed to help make creating, deploying, and managing cloud services easier by providing a complete "stack" of features and components for cloud environments. Apache Cloud Stack An operational driver for decision making and input for risk management Business Requirement The phrase used to describe a software application accessed via the Internet; may include an agent or applet installed locally on the user's device. cloud app Subject matter expert for cloud computing infrastructure and deployment. Cloud Architect Backing up data to a remote, cloud-based server. As a form of cloud storage, cloud backup data is stored in an accessible form from multiple distributed resources that comprise a cloud. Cloud Backup A type of computing, compared to grid computing, that relies on ensuring computing resources rather than having local server or personal devices to handle applications. The goal of cloud computing is to apply traditional supercomputing or high-performance computing power, normally used by military and research facilities, to perform tens of trillions of computations per second and consumer-oriented applications such as financial portfolios, or even to deliver personalized information or power immersive computer games. Cloud Computing A company that purchases hosting services from a cloud server hosting or computing provider and then resells them to its own customers. Cloud Computing Reseller The process of transitioning all or part of a company's data, applications, and services from onsite premises to the cloud, where the information can be provided over the Internet on an on-demand basis. Cloud Migration A phrase frequently used in place of PaaS to denote an association to cloud computing. Cloud OS The ability to move applications and associated data between one cloud provider and another, or between legacy and cloud environments. Cloud Portability A service provider that offers customer storage or software solutions available via a public network, usually the Internet. The _________ dictates both the technology and operational procedures involved. Cloud Provider Typically a third-party entity or company that looks to extend or enhance value to multiple customers of cloud-based services through relationships with multiple cloud service providers. It acts as a liaison between cloud services customers and cloud service providers, selecting the best provider for each customer and monitoring the services CSB The storage of data online in the cloud, wherein a company's data is stored in an accessible form from multiple distributed and connected resources that comprise a cloud. cloud storage Load and performance testing conducted on the applications and services provided by a cloud provider, particularly the capability to access the services, in order to ensure optimal performance and scalability under a wide variety of conditions. cloud testing
