Some questions that still vex my mind thinking about the clouds ...
1. Will the search engine be charged if they want to index your public clouds?
2. What will be the change in the developer productivity matrix when cloud based platforms and services will be in place?
3. Can we have Search engines integrated to the Cloud based platforms.
4. How will Search Engines crawl data shared in public cloud, and secured in virtual private clouds? Do you have an API at least in place for this?
5. How will you handle concurrency in cloud based transactions?
6. Do we have a cloud based development lifecycle and delivery model in place?
9. Is Single-Sign-On ( SSO ) relevant only for federated applications?
