If I were to upload a 50kb object to S3 (standard tier), about how many unique physical copies would exist?

- cyberax 3y agoAt least 3.
- bigiain 3y agoAt least 3, in at least 3 seperate datacenters. According to https://nuclearsecrecy.com/nukemap/ https://nuclearsecrecy.com/nukemap/ - it'd take at least a 1 megaton warhead to take out two of the ap-southeast-2 datacenters, and over 10MT to take out 3. I suspect you'd need a lot less than that though, the 1MT warhead would probably take out enough outside-the-datacenter infrastructure to take the entire AZ offline. I don't care too much though, if someone's dropped a warhead that close to home I have other things to worry about than whether all the cat pictures and audit logs survive.

- dmvdoug 3y agoI’m picturing you having a slideshow of audit logs that you make guests to your home sit down and watch with you, like the vacation pictures slideshow of old.
- tomcam 3y agoYes but my audit logs are special and everyone just loves them, although they playfully act bored
- konfusinomicon 3y agoscrolling through them like it's the matrix can't be all that boring!
- bigiain 3y agoAwwwww! Check out this cute little IAM audit log! Look at its funny little fizzy privilege escalation! I just want to scratch it's belly until it p0wns the whole prod deployment.
- tomcam 3y agoOh, like you don’t? We’re among friends here.
- tom910 3y agoI think lees. Why AWS need to store 3 times if they can use Reed-Solomon algorithms (or similar) and decrease this number to 2 or 1.5 and save a lot of storage space
- Kluggy 3y agoReed-Solomon would allow you to lose any one of the three and recover. Losing two would be catastrophic. AWS's guarantee is that you can lose two of the three copies and still have all the data. You can't do that without three complete copies.
- flybarrel 3y ago1MT will take out the infrastructure to make the data not Available. However the data is still in the 3rd datacenter, making it still accessible therefore no compromising on Durable but yes we don't need the cat pictures when that is close to home :)
- bigiain 3y agoI'm guessing that even though the 3rd datacenter is about 35km away from the other 2, and so the building isn't in the expected destruction zone of a 1MT warhead, the damage to the city's electricity/water/network infrastructure would take the 3rd datacenter offline as well - so while your cat pictures are probably still in existence on the no-longer-spinning-rust there, they'd be unaccessible for quite some time.
