اسلاید 8: The cloud - definitions and hypeIs the cloud:Infrastructure aaS?Grid / utility / on demand computingShared utility eg Amazon EC2Platform aaS?Ready-for-deployment scalable application platformGoogle apps, Force.com, Heroku, Bungee LabsMicrosoft! (Azure)Software aaS?Used to be called application service providers Multitenanted architectures: SalesForce.com,Xero ...many, many others (3000 worldwide at least)Wide area SOA?Universe of all (web) servicesWS-* and REST (and Etch?) standardsData as a service? (StrikeIron) *aaS?Universe of all economic servicesCan traditional services (law, accountancy, plumbing) be included in the logical Cloud?
اسلاید 9: IDC Definitions (Sept 2008)Cloud Services = Consumer and Business products, Services, and solutions that are delivered and consumed in real-time over the InternetCloud Computing = an emerging IT development, deployment and delivery model, enabling real-time delivery of products, services and solutions over the Internet (i.e., enabling cloud services) (From http://blogs.idc.com/ie/?p=190)
اسلاید 10: Key cloud services attributesOff-site, third-party provider Accessed via Internet Minimal/no IT skills needed to implement Provisioning:Self-service requesting Near-real-time deployment Dynamic and fine-grained scalingPricing model:Fine-grained Usage-based (at least available as an option)User interface: browsers and their successors System interface: Web services APIs Shared resources/common versions (customization around the shared resources) According to research firm IDC

اسلاید 36: When to use cloud services now?Non-sensitive binary object storage (docs, pdfs, images etc) use S3 or similar NOW!Moving server hosting to the Cloud: business case needs developingManagement tools not matureNot ready for Enterprise apps - but soonAzure will be a key player for PaaSGoogle, SalesForce(?) main competitorsLots of nichesSaaSWhen setting up a new business, use it now! Dont saddle your business with expensive, inflexible, rapidly depreciating assets you dont need!
