Amazon's S3 Cloud Service Turns Into A Puff Of Smoke

摘要

Amazon.com's simple storage Service suffered an eight-hour failure on July 20, causing outages at companies that depend on S3 for file storage. It's the second major S3 outage this year-service was lost for two hours in February-and a reminder that the increasingly fashionable cloud computing model isn't always dependable. "Any downtime is unacceptable and we won't be satisfied until it is perfect," Amazon said in a statement that, in addition to explaining some of what went wrong, defended S3's overall reliability.
