Pay for the bandwidth and server resources that you need. When your push is done then turn the whole thing off!

what is the cloud
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.

slide26

SaaS

  • 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.
slide27

You need to host 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

slide28

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.
