Cloud ComputingDefinition:Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurablecomputing resources: • NETWORKS • SERVERS • STORAGE • APPLICATIONS • SERVICESthat can be rapidly provisioned and released with minimalmanagement effort or service provider interaction.
Cloud ComputingDefinition:Product your own electricity vs. Paid per consumeFrom Water-Wheel to Utility Power
Cloud Computing Cloud Service Characteristics• On-demand self service Possibility for end users to sign up an receive the service without delays• Broad network access Service can be accessed via standards platforms• Resource pooling Resources are pooled across multiple customers• Rapid elasticity Capacity can scale to cope with demand peaks• Measured service Billing is metered and delivered as a utility service
Cloud ComputingEnablers:I. Virtualization – The ability to increase computing efficiencyII. Democratization of computing – Bringing enterprise scale infrastructure to small and medium businessesIII. Scalability and fast provisioning – Bringing web scale IT at a rapid paceIV. Commoditization of infrastructure – Enabling IT to focus on the strategic aspects of its role Cloud Computing: Need all Enablers working together
Cloud ComputingI. Virtualization: The ability to increase computing efficiencyEnabling pseudo-servers to be run on one physical device. The division of a single physical server into Multiple “virtual” servers containing multiple sets of segregated data. Cloud Computer Backbone
Cloud ComputingI. Virtualization: The ability to increase computing efficiency Increase • Flexibility • Resource allocation • Efficiency gains in terms of processing power Decrease • Electric power • Space • Cooling
Cloud ComputingII. Democratization of computing: Bringing enterprise scale infrastructure to small and medium businessesEasy business development, enabling saving in: • Hardware • Software Licenses Ability for small and medium companies to rapidly scale infrastructure to levels only achieved by largest organizations.
Cloud ComputingIII. Scalability and Fast Provisioning:Cloud Computing enables organizations to: 1. Maintain infrastructure at required levels at all times 2. Cost saving originated in the aggregated cost per unit. Paying only for what is required when is required Despite the cost per Unit from an Utility Service Provider, can be higher than an owned resource.
Cloud ComputingIII. Scalability and Fast Provisioning: For Organizations where workload has processing picks. There are two situations: 1. Over provision of servers: Creating unused capacity and higher cost per process. 2. Under provision of servers: Creating impacts in terms of quality of service levels.
Cloud ComputingIV. Commoditization of Infrastructure Enabling IT to focus on the strategic aspects of its roleCloud Computing offers:• The ability for IT departments to apply resources as, and where, they are needed.• To the organizations to focus in their core business. Business Agility is the main reason to migrate to Cloud Computing (over Cost savings)
Cloud ComputingCategories within Cloud Computing• SaaS: Software as a Service Applications are designed for end- users, delivered over the web.• PaaS: Platform as a Service Set of tools and services designed to make coding and deploying those applications quick and efficient.• IaaS: Infrastructure as a Service Hardware or Software that powers it all, includes: Servers, storage, networks and operating systems.
