Editor's Notes
- #4: The world is changing more and more fast You have to minimize NRE You must support unexpected demand You must provide top service (people now leaves cell operator after single incident, rather then 5, 10 years ago Firms a vulnerable – Citi worth 20Bill $ instead of 200 Bill a year ago Break and Mortar bookstores 15 years ago and Amazon…. Will it happen again to banks, insurance, real estate agencies… IS YOUR MARKET THE NEXT FOR PENETRATION – Finance? Real Estate? How to win a rival that is not existing yet? http://www.johnmwillis.com/ibm/cloud-computing-and-the-enterprise/ -
- #67: Start with nothing: storage, FW, LB, Server and grow… Can buy servers for more than hour
