    • 1. An Introduction to SaaS and Cloud Computing Ross Cooney
    • 2. The challenge
      • Add new services for your users quickly and cost effectively
    • 3. Expand your Infrastructure! Buy new servers, increase your software costs, provision more datacenter capacity!!
    • 4. Look to the cloud! Pay for the bandwidth and server resources that you need. When your push is done then turn the whole thing off!
    • 5. What is the cloud ?
      • IT as a service
      • Cloud allows access to services without user technical knowledge or control of supporting infrastructure
      • Best described in terms of what happened to mechanical power over 100 yrs ago
      • Now computers are simple devices connected to the larger cloud
      • Data processing, storage and software applications that used to run locally are now being supplied by big central computing stations. They're becoming, in essence, computing utilities.
      What is Cloud Computing?
    • 6. The hype Cluster Computing Cloud Computing Grid Computing 
    • 7. IaaS Infrastructure as a Service PaaS Platform as a Service SaaS Software as a Service
    • 8. SaaS Software as a Service
    • 9.
      • Software delivery model
      • Increasingly popular with SMEs
      • No hardware or software to manage
      • Service delivered through a browser
      SaaS
    • 10.
      • Advantages
      • Pay per use
      • Instant Scalability

    • 12. PaaS Platform as a Service
    • 13.
      • Platform delivery model
      • Platforms are built upon Infrastructure, which is expensive
      • Estimating demand is not a science!
      • Platform management is not fun!

      IaaS PaaS SaaS
    • 25.
      • Examples of usage
    • 26.
      • Your current CRM package is not managing the load or you simply don’t want to host it in-house….use a SaaS provider such as Salesforce.com
      • Your email is hosted on an exchange server in your office and it is very slow…outsource this using Hosted Exchange.
      SaaS
    • 27.
      • You need to h ost a large file (5Mb) on your website and make it available for 35,000 users for only two months duration. Use Cloud Front from Amazon.
      • You want to start storage services on your network for a large number of files and you do not have the storage capacity…use Amazon S3.
      PaaS
    • 28.
      • You want to run a batch job but you don’t have the infrastructure necessary to run it in a timely manner. Use Amazon EC2.
      • You want to host a website, but only for a few days. Use Flexiscale.
