How good is security on the cloud? It's as good as your cloud provider. It's a lesson for Mike Bradshaw, director of Google's federal government group. He recently testified "The cloud enhances security by enabling data to be stored centrally with continuous and automated network analysis and protection." True, but what if Google makes those private documents on the cloud public? Microsoft was more realistic when discussing security in the cloud, stating the cloud "presents new security, privacy and reliability challenges, which raise questions about functional responsibility (who must maintain controls) and legal accountability (who is legally accountable if those controls fail)." Information Week has the full details.
I was surprised to hear that 75% of Twitter traffic comes from the REST API. Surprised because I thought the number would be even higher. Twitter has slashed API limits in half across the board (even for its own official apps). Currently the public API rate stands at a miniscule 75/hour. The Fail Whale problem has been Twitter's own doing: they clearly should not have been making significant network changes as the World Cup started. They have not recovered and it's been an embarrassing month. Take a look at (note: they aren't posting all the errors, the real picture is worse).
