Five different ways we can compute
Tel. 01299 405719 Mob. 07792569451 Web. http://tdm.info
1. Local Device e.g. Desktop, Laptop, Netbook, PDA, Games Console, Watch(?), Fridge(?)
2. Local Server e.g. Dell or IBM running Windows or Linux
3. Single SaaS (Software as a Service) e.g. SalesForce.com
4. Open Cloud e.g. TDM, ULCC
5. Corporate Cloud e.g. Windows Azure, Google Apps, Amazon EC2
= Choice with Trade-offs
(1) Your own Local Device
Positives
• You can work on the train! (No Broadband Required)
• High Performance
• “Tailorability”
• Very private, locally stored data
• Mobile augmented reality
Negatives
• Poor for Community Interaction / Collaboration
• Disincentive for corporate interoperability
