What are 2 major dangers that can affect availability with Cloud deployments due to big economies of scale?
ANSWER: Amplication & Isolation. Amplication can incur issues when automated “fixes” and larger failures can make recovering more difficult (e.g. try rebooting all your iSCSI booted hosts at the same time). Isolation since a user/company can cause problems for other companies sharing the service (e.g. a DoS can effect thousands of companies).
