A private cloud refers to cloud computing resources used exclusively by a single business or organisation. Each model represents a different part of the cloud computing stack. A cloud computing platform can be assembled from a distributed set of machines in different locations, connected to a single network or hub service. Cloud Computing (CLOUD), 2014 IEEE 7th International Conference on. Linux containers run in isolated partitions of a single Linux kernel running directly on the physical hardware. , Cloud computing uses concepts from utility computing to provide metrics for the services used.  Under the dPaaS model, the PaaS provider, not the customer, manages the development and execution of programs by building data applications for the customer. The early code came from NASA's Nebula platform as well as from Rackspace's Cloud Files platform.

", In 2008, the U.S. National Science Foundation began the Cluster Exploratory program to fund academic research using Google-IBM cluster technology to analyze massive amounts of data,, In 2009, the government of France announced Project Andromède to create a "sovereign cloud" or national cloud computing, with the government to spend €285 million. A. Google 101 B. IBM Deep blue C. Microsoft Azure D. Amazon EC2 ANS:B. ), whether managed internally or by a third-party, and either hosted internally or externally. Von Laszewski, Gregor, et al. Microsoft Azure is an example of a public cloud. Many Terms of Service agreements are silent on the question of ownership. a) SQL Server is having enormous impact on cloud computing b) Amazon.com’s services represent the largest pure Infrastructure as a Service (IAAS) c) EC2 is a Platform as a Service (PaaS) market d) None of the mentioned View Answer  Some small businesses that don't have expertise in IT security could find that it's more secure for them to use a public cloud. Pools of hypervisors within the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements. Fewer options at a much cheaper price: it's a feature, not a bug."  This cloud offering is poised to be the first to provide users with access to an integrated set of IT solutions, including the Applications (SaaS), Platform (PaaS), and Infrastructure (IaaS) layers. On June 7, 2012, Oracle announced the Oracle Cloud. Cloud computing is a term used to describe the use of hardware and software delivered via network (usually the Internet). The cloud aims to cut costs and helps the users focus on their core business instead of being impeded by IT obstacles. Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning. Some examples of this include the Dropbox security breach, and iCloud 2014 leak. The benefits of cloud computing services include the ability to scale elastically.  In Wired's April 1994 feature "Bill and Andy's Excellent Adventure II", Andy Hertzfeld commented on Telescript, General Magic's distributed programming language: "The beauty of Telescript ... is that now, instead of just having a device to program, we now have the entire Cloud out there, where a single program can go and travel to many different sources of information and create a sort of a virtual service. Users can transparently deploy and scale applications without knowledge of the cloud's hardware diversity. Several studies aim at comparing these open source offerings based on a set of criteria. - Definition from WhatIs.com", "What is hybrid cloud computing?

Microsoft is a leading global provider of cloud computing services for businesses of all sizes. For instance, sworn translators working under the stipulations of an NDA, might face problems regarding sensitive data that are not encrypted.. , The NIST's definition of cloud computing describes IaaS as "where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The word cloud was used as a metaphor for the Internet and a standardized cloud-like shape was used to denote a network on telephony schematics. In addition, to use by General Magic itself, it was also used in promoting AT&T's associated PersonaLink Services. Google and Microsoft followed soon after. In cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, bandwidth—right when it is needed and from the right geographic location.  Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and "bursts" to a public cloud when the demand for computing capacity increases.  The initiative failed badly and Cloudwatt was shut down on 1 February 2020.

Function as a service (FaaS) is a service-hosted remote procedure call that leverages serverless computing to enable the deployment of individual functions in the cloud that run in response to events. No one had conceived that before. You access these services and manage your account using a web browser. This model offers the versatility and convenience of the cloud, while preserving the management, control and security common to local data centers.  The main enabling technology for cloud computing is virtualization.  Penguin Computing launched its HPC cloud in 2016 as alternative to Amazon's EC2 Elastic Compute Cloud, which uses virtualized computing nodes.. The cloud represents nearly 60% of Amazon’s total operating income of $12.4 billion in 2018, despite sales representing only 11% of the company’s total revenue. As described by Though service-oriented architecture advocates "Everything as a service" (with the acronyms EaaS or XaaS, or simply aas), cloud-computing providers offer their "services" according to different models, of which the three standard models per NIST are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls). There are three main cloud computing types, with additional ones evolving—software-as-a-service (SaaS) for web-based applications, infrastructure-as-a-service (IaaS) for Internet-based access to storage and computing power, and platform-as-a-service (PaaS) that gives … Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. In this model, the cloud user patches and maintains the operating systems and the application software. , HPC cloud refers to the use of cloud computing services and infrastructure to execute high-performance computing (HPC) applications. There is the risk that end users do not understand the issues involved when signing on to a cloud service (persons sometimes don't read the many pages of the terms of service agreement, and just click "Accept" without reading). Cloud computing is changing our lives in many ways. A. Wireless B. For example, an organization may store sensitive client data in house on a private cloud application, but interconnect that application to a business intelligence application provided on a public cloud as a software service. With some PaaS, the underlying computer and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually. Software as a service is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. , In April 2008, Google released the beta version of Google App Engine. This eliminates the need to install and run the application on the cloud user's own computers, which simplifies maintenance and support.  Users can encrypt data that is processed or stored within the cloud to prevent unauthorized access. Since then, cloud computing has been evolved from static clients to dynamic ones from software to services. The term is generally used to describe data centers available to many users over the Internet. iPaaS enables customers to develop, execute and govern integration flows. , Privacy and confidentiality are big concerns in some activities. Elastic provision implies intelligence in the use of tight or loose coupling as applied to mechanisms such as these and others. Also explore over 21 similar quizzes in this category. Andy Hertzfeld: "The beauty of Telescript," says Andy, "is that now, instead of just having a device to program, we now have the entire Cloud out there, where a single program can go and travel to many different sources of information and create a sort of a virtual service. Cloud computing is beneficial to many enterprises; it lowers costs and allows them to focus on competence instead of on matters of IT and infrastructure. To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. Broad network access. Often, these customer- and partner-facing systems will lead the way to the creation of new cloud-native applications, and the expertise gained can also be used for new internal custom …  As computers became more diffused, scientists and technologists explored ways to make large-scale computing power available to more users through time-sharing. Services include user management, push notifications, integration with social networking services and more.  Despite the name, it does not actually involve running code without servers. Get Azure innovation everywhere—bring the agility and innovation of cloud computing to your on-premises workloads. Hard drives C. People D. Internet ANS:D. 10. Many companies now prefer to rely on cloud based service providers for highly specialized computing … Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses.. , The NIST's definition of cloud computing defines Platform as a Service as:. a) The massive scale of cloud computing systems was enabled by the popularization of the Internet b) Soft computing represents a real paradigm shift in the way in which systems are deployed c) Cloud computing makes the long-held dream of utility computing possible with a pay-as-you-go, infinitely scalable, universally available system The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources like servers and storage over the Internet. Abstract Image Management and Universal Image Registration for Cloud and HPC Infrastructures ", IEEE 5th International Conference on Cloud Computing (CLOUD), 2012. Metzler, Jim; Taylor, Steve. During the 1960s, the initial concepts of time-sharing became popularized via RJE (Remote Job Entry); this terminology was mostly associated with large vendors such as IBM and DEC. Full-time-sharing solutions were available by the early 1970s on such platforms as Multics (on GE hardware), Cambridge CTSS, and the earliest UNIX ports (on DEC hardware).  This capability enables hybrid clouds to employ cloud bursting for scaling across clouds. Cloud users do not manage the cloud infrastructure and platform where the application runs. The provider typically develops toolkit and standards for development and channels for distribution and payment. Cloud computing is still a subject of research. It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service. As a result, there could be unauthorized access to the data. The term comes from the use of cloud shaped symbol that represents abstraction of rather complex infrastructure that enables the work of software, hardware, computation and remote services. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. Cloud providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed. Private cloud services are delivered from a business's data center to internal users. Use intelligent models to help engage customers and provide valuable insights from the data captured.

Reduce application development cost and time by using cloud infrastructures that can easily be scaled up or down. This process is transparent to the cloud user, who sees only a single access-point. Diaz, Javier et al. " Cloud computing extended this boundary to cover all servers as well as the network infrastructure. (Part 1) – Schneier on Security", "Disadvantages of Cloud Computing (Part 1) – Limited control and flexibility", "Cloud solutions for translation, yes or no? He also suggests that "the cloud provider might not meet your legal needs" and that businesses need to weigh the benefits of cloud computing against the risks. Varied use cases for hybrid cloud composition exist. The Penguin On Demand (POD) cloud was one of the first non-virtualized remote HPC services offered on a pay-as-you-go basis.  Among the various components of the Smarter Computing foundation, cloud computing is a critical part. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider.  A hybrid cloud service crosses isolation and provider boundaries so that it can't be simply put in one category of private, public, or community cloud service. "Formulating Cost-Effective Monitoring Strategies for Service-based Systems." ), peak-load capacity increases (users need not engineer and pay for the resources and equipment to meet their highest possible load-levels).  Major cloud technology companies invest billions of dollars per year in cloud Research and Development. Cloud Computing Market Share Breakdown – AWS vs. Azure vs. Google Cloud When we originally published this blog in 2018, we included a market share breakdown from analyst Canalys, which reported AWS in the lead owning about a third of the market, Microsoft in second with about 15 percent, and Google sitting around 5 percent.  Under the iPaaS integration model, customers drive the development and deployment of integrations without installing or managing any hardware or middleware. A cross-platform hybrid cloud is usually powered by different CPU architectures, for example, x86-64 and ARM, underneath. It could accidentally or deliberately alter or delete information. Not all clouds are the same and not one type of cloud computing is right for everyone. , Several factors like the functionality of the solutions, cost, integrational and organizational aspects as well as safety & security are influencing the decision of enterprises and organizations to choose a public cloud or on-premise solution. There are three different ways to deploy cloud services: on a public cloud, private cloud or hybrid cloud. If you aren’t familiar with this topic, cloud computing is when hardware (servers, storage, etc.) The advantages include enhanced runtime flexibility and adaptive memory processing unique to virtualized interface models. SaaS applications may be integrated with cloud storage or File hosting services, which is the case with Google Docs being integrated with Google Drive and Word Online being integrated with Onedrive. A restaurant with a limited menu is cheaper than a personal chef who can cook anything you want. "There are some real Achilles' heels in the cloud infrastructure that are making big holes for the bad guys to get into".  A driving factor in the evolution of cloud computing has been chief technology officers seeking to minimize risk of internal outages and mitigate the complexity of housing network and computing hardware in-house. The first cloud computing services are barely a decade old, but already a variety of organisations—from tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all sorts of reasons. To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time.  IaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles. Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over a loose coupling mechanism such as a messaging queue. Most public-cloud providers offer direct-connection services that allow customers to securely link their legacy data centers to their cloud-resident applications. Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources like servers and storage over the Internet.Microsoft Azure is an example of a public cloud. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand, providing the burst computing capability: high computing power at certain periods of peak demand. In the 1990s, telecommunications companies, who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network (VPN) services with comparable quality of service, but at a lower cost. , By mid-2008, Gartner saw an opportunity for cloud computing "to shape the relationship among consumers of IT services, those who use IT services and those who sell them" and observed that "organizations are switching from company-owned hardware and software assets to per-use service-based models" so that the "projected shift to computing ... will result in dramatic growth in IT products in some areas and significant reductions in other areas. ", "How Cloudbursting "Rightsizes" the Data Center", "Cross-Platform Hybrid Cloud with Docker", "Pivotal's head of products: We're moving to a multi-cloud world", "Polycloud: a better alternative to cloud agnosticism", "Is the Cloud Finally Ready for Big Data? , An alternative approach is to deploy a tool that processes in the cloud itself.  The specialized model of hybrid cloud, which is built atop heterogeneous hardware, is called "Cross-platform Hybrid Cloud". Here are seven common reasons organisations are turning to cloud computing services: Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, the IT experts for managing the infrastructure. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). It differs from Multi cloud in that it is not designed to increase flexibility or mitigate against failures but is rather used to allow an organization to achieve more that could be done with a single provider. PaaS is designed to make it easier for developers to quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network and databases needed for development. To accommodate a large number of cloud users, cloud applications can be multitenant, meaning that any machine may serve more than one cloud-user organization.  Many cloud providers can share information with third parties if necessary for purposes of law and order without a warrant. Industry experts believe that this trend will only continue to grow and develop even further in the coming few years. Learn more about public, private and hybrid clouds. Cloud computing operates on a similar principle as web-based email clients, allowing users to access all of the features and files of the system without having to keep the bulk of that system on their own computers.  They began to use the cloud symbol to denote the demarcation point between what the provider was responsible for and what users were responsible for. Cloud computing makes data backup, disaster recovery and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s network. Try this amazing Cloud Computing Knowledge Trivia! The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. Take advantage of cloud-native technologies and approaches, such as containers, Kubernetes, microservices architecture, API-driven communication and DevOps. private cloud. Cloud computing poses privacy concerns because the service provider can access the data that is in the cloud at any time.  However, many large enterprises maintain at least two internet providers, using different entry points into their workplaces, some even use 4G as a third fallback. In cloud computing, the control of the back end infrastructure is limited to the cloud vendor only. "Infrastructure as a service" (IaaS) refers to online services that provide high-level APIs used to abstract various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup, etc. Hybrid cloud is a composition of a public cloud and a private environment, such as a private cloud or on-premises resources, that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Access Visual Studio, Azure credits, Azure DevOps and many other resources for creating, deploying and managing applications. That is permitted in their privacy policies, which users must agree to before they start using cloud services.  In the SaaS model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients.  Serverless computing is so named because the business or person that owns the system does not have to purchase, rent or provision servers or virtual machines for the back-end code to run on. Cloud applications differ from other applications in their scalability—which can be achieved by cloning tasks onto multiple virtual machines at run-time to meet changing work demand. , The issue of carrying out investigations where the cloud storage devices cannot be physically accessed has generated a number of changes to the way that digital evidence is located and collected. ", "Your infrastructure's in the cloud and the Internet goes down. Autonomic computing automates the process through which the user can provision resources on-demand. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. One drawback of SaaS comes with storing the users' data on the cloud provider's server. Quiz quiz which has been attempted 13582 times by avid quiz takers. , On March 1, 2011, IBM announced the IBM SmartCloud framework to support Smarter Planet. utilisation and efficiency improvements for systems that are often only 10–20% utilised. Additionally, Eugene Schultz, chief technology officer at Emagined Security, said that hackers are spending substantial time and effort looking for ways to penetrate the cloud. Unify your data across teams, divisions and locations in the cloud. "Comparison of multiple cloud frameworks. Cloud engineering is the application of engineering disciplines to cloud computing. This enables the business to reallocate IT operations costs away from hardware/software spending and from personnel expenses, towards meeting other goals. Which of these should a company consider before implementing cloud computing …  Undertaking a private cloud project requires significant engagement to virtualize the business environment, and requires the organization to reevaluate decisions about existing resources. On-site datacenters typically require a lot of “racking and stacking”—hardware setup, software patching, and other time-consuming IT management chores. , Poly cloud refers to the use of multiple public clouds for the purpose of leveraging specific services that each provider offers. Cost reductions are claimed by cloud providers. Cloud providers often decide on the management policies, which moderates what the cloud users are able to do with their deployment. If the connection to the user is relatively close, it may be designated an edge server. Virtualization software separates a physical computing device into one or more "virtual" devices, each of which can be easily used and managed to perform computing tasks. It can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities. "What can OpenStack adopt from a Ganeti-based open-source IaaS?."
