The document discusses cloud computing, defining it as computing based on sharing resources over the internet rather than local servers. It provides a brief history of cloud computing emerging in the 1990s with virtual private networks and salesforce.com launching web applications in 1999. The document outlines how libraries use cloud computing services like YouTube, Facebook, and Gmail for communication and sharing resources with patrons.
Cloud computing involves sharing configurable computing resources like servers, storage, databases and software that are delivered as an Internet service in a pay-as-you-go model. It provides on-demand access to a shared pool of configurable computing resources like networks, servers, storage, applications and services. Cloud services can be broadly divided into infrastructure as a service, platform as a service and software as a service. Cloud computing offers advantages like lower costs, improved performance, universal access and increased collaboration. However, it also faces challenges like dependence on internet connectivity and potential security and data loss issues.
Mobile cloud computing combines cloud computing and mobile networks to provide benefits to mobile users, network providers, and cloud providers. It allows resource-intensive tasks to be processed in the cloud rather than on mobile devices, extending battery life and improving storage and processing capabilities. Key advantages include improving reliability and availability of data and services, enabling dynamic provisioning and scalability, and ease of integration. Several techniques for offloading computation and data to the cloud have been developed. Open issues include determining what tasks to offload, addressing low bandwidth constraints, and ensuring security and privacy when data and processing occur externally.
Cloud computing has the potential to be more energy efficient than traditional computing by enabling better utilization of computing resources and data centers. However, cloud computing is still developing and the full environmental benefits have not yet been realized. While some view cloud computing as a greener alternative, others are skeptical or think the green benefits are overhyped. As cloud computing continues to grow, making cloud infrastructure and services more energy efficient will be important for cloud computing to truly be considered green.
Cloud computing allows users to access computing resources like software, data storage, and processing power over the internet rather than maintaining and operating them locally. It provides resources on demand in a manner similar to a public utility. The document discusses the background of cloud computing including its origins in centralized mainframe systems. It outlines the key characteristics, economics, layers, types, advantages, and disadvantages of cloud computing and provides examples of cloud computing vendors and services.

Seminar on cloud computing by Prashant GuptaPrashant Gupta
Cloud computing relies on sharing computing resources over the internet rather than local servers. It provides software, platforms, and infrastructure as on-demand services with various advantages like lower costs, improved performance, and universal access, but also disadvantages like requiring constant internet and potential security and reliability issues. The document discusses concepts like cloud architecture, service models (SaaS, PaaS, IaaS), storage types (public, private, hybrid cloud), and advantages and disadvantages of cloud computing.
This document discusses cloud computing, including definitions of cloud computing, the different types of cloud computing services (SaaS, PaaS, IaaS), examples of cloud platforms like Google Cloud, and advantages like reduced costs, scalability, and environmental benefits compared to traditional computing. It also notes some disadvantages like reliance on internet connectivity and lack of access offline.
The document discusses cloud computing, providing an overview of its key features, history, service models, deployment models, advantages, and disadvantages. It notes that cloud computing allows for resource scalability, on-demand access, and pay-as-you-go pricing. Historically, the concept originated in the 1960s but failed due to network limitations, while current cloud computing grew out of grid computing and data center utilization in the 2000s. The main service models are infrastructure as a service, platform as a service, and software as a service, while the primary deployment models are public, private, community, and hybrid clouds. The advantages include ubiquitous access, no hardware ownership, and low costs, but disadvantages involve privacy, security,
This document presents an introduction to cloud computing. It defines cloud computing as using remote servers and the internet to maintain data and applications. It describes the characteristics of cloud computing including APIs, virtualization, reliability, and security. It discusses the different types of cloud including public, private, community, and hybrid cloud. It also defines the three main cloud stacks: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The benefits of cloud computing are reduced costs, improved accessibility and flexibility. Cloud security and uses of cloud computing are also briefly discussed.
Cloud computing involves delivering computing services over the Internet. Instead of running programs locally, users access software and storage that resides on remote servers in the "cloud." The concept originated in the 1950s but Amazon launched the first major public cloud in 2006. Cloud computing has three main components - clients that access the cloud, distributed servers that host applications and data, and data centers that house these servers. There are different types of clients, deployment models for clouds, service models, and cloud computing enables scalability, reliability, and efficiency for applications accessed over the Internet like email, social media, and search engines.

1.
2. cloud computing – это технология обработки данных, в которой компьютерные ресурсы и мощности предоставляется пользователю как Интернет-сервис.
3. Пользователь имеет доступ к собственным данным, но не может управлять и не должен заботиться об инфраструктуре, операционной системе и собственно программном обеспечении, с которым он работает.
4.
5. Например, Google Apps обеспечивает приложения для бизнеса в режиме онлайн, доступ к которым происходит с помощью Интернет-браузера, в то время как ПО и данные хранятся на серверах Google. Операционная система Google Chrome OS целиком основана на облачных вычислениях.
6. Согласно документу IEEE, опубликованному в 2008 году, «Облачная обработка данных — это парадигма, в рамках которой информация постоянно хранится на серверах в сети Интернет и временно кэшируется на клиентской стороне, например, на персональных компьютерах, игровых приставках, ноутбуках, смартфонах и т. д.»
7.
8. Виды: Публичные облака (общедоступные ) — абонентом предлагаемых сервисов может стать любая компания и индивидуальный пользователь. Предлагают хранение на базе «коммунальных» (multi-tenancy) инфраструктур, легкий и доступный по цене способ развертывания веб-сайтов или бизнес-систем, с большими возможностями масштабирования, которые в других решениях были бы недоступны. Примеры: онлайновые сервисы Amazon EC2 и Simple Storage Service (S3), Google Apps/Docs, Salesforce.com, Microsoft Office Web.
9. Частные облака — абонентами являются корпоративные офисы и подразделения, деловые партнеры, поставщики сырья, реселлеры, участники производственной цепочки и другие организации. Защищены файрволлом, не выходят за пределы замкнутой внутренней сети, обеспечивается гораздо более высокий уровень защиты .
10. Преимущества облачных вычислений очевидны и убедительны: широкие возможности виртуализации ресурсов при необходимости, высокая доступность, более легкое администрирование программных активов, «эластичное» масштабирование.
11.
12. Частное облако представляет собой безопасную ИТ-инфраструктуру, которая контролируется и эксплуатируется в интересах одной-единственной организации. Организация может управлять частным облаком самостоятельно или поручить эту задачу внешнему подрядчику.
