Some are snarky, some are true, and all come from hard-won experience. These are #awsfacts, and for every ten (10) retweets this tweet gets, I will share one of them with you until I either run out or get bored.

S3 "Reduced Redundancy" storage is mostly deprecated; stop using it. In most regions it costs *more* than Standard storage and gets you absolutely nothing but a worse SLA. #awsfacts

It doesn't matter how fast the EBS volume is--you're throttled by some instance limits that vary per instance size and family, so faster volume types are just burning money. docs.aws.amazon.com/AWSEC2/latest/… has the details. #awsfacts

You all know the Rumplestiltskin story, but who the hell named a baby "Rumplestiltskin" in the first place? @awscloud. #awsfacts

S3 Infrequent Access and S3 Infrequent Access One Zone both have the same SLA--because "theoretical loss of an AZ" and other disasters don't factor into SLA calculations. HAPPY DR PLANNING SEASON! #awsfacts

Most emails from AWS employees ask for feedback at the bottom. As an AWS job applicant you will never receive feedback other than "hire," "no hire," or "they called the police to remove you from the building." #awsfacts

Christmas may come once a year, but the AWS bill comes once a month, usually around the third. Larger companies with enterprise contracts usually see them somewhere between the 8th and the 15th historically.

But they can be... later than that. #awsfacts

Move 1TB between two availability zones in the same region, and it will cost you $20.48 and show up on the bill as 2TB of data transfer. #awsfacts

Move 1TB between two different regions, and it will cost you $20.48 and show up on the bill as 1TB of data transfer. #awsfacts

Move 1TB between us-east-1 and us-east-2, and it will cost you $10.24 and show up on the bill as 1TB of data transfer. #awsfacts

"F*ck, Marry, Kill" isn't just a sophomoric schoolyard game; it's also the AWS partner strategy. #awsfacts

CloudFront distributions and Lambda Edge functions log to most / all of the public regions; you can't tell them to directly log everything to a central location. Now you know why there are so many log analytics companies. #awsfacts

Many aspects of how @awscloud services work behind the scenes are non-public. Sometimes it's because they don't want to lose a competitive advantage.

Other times it's because they are deeply and profoundly ashamed. #awsfacts

The business tier of @AWSSupport costs you at least $100 a month. Enterprise support costs you at least $15,000 a month--but the latter applies to every account you have whereas the former is per-account. With enough accounts it saves money. #awsfacts

The AWS product strategy is highly confidential, but I've attached it to this tweet anyway. #awsfacts
