for people blathering about “just put twitter in the cloud” we tried that. i was there. so just to put some numbers out there, let’s assume aws gave you a 60% discount. now you’re talking approximately 500,000 m6gd.12xlarge systems (new hw was bigger). that’s $300MM monthly and before you add in little things like bandwidth. probably $10MM a month in S3. it’s just absurd.

there is a reason after investing many thousands of staff+ hours twitter was careful about what it moved.
