I am trying to find updated information regarding aws best practices when it comes to multi-tenant data partitioning in S3.

From what I know and what I studied for when I did my AWS Solutions Architect Professional exam, The best way to handle scalability was with a prefix-per-tenant size buckets were restricted to only 100 buckets per account. However, now that you have a limit of 10,000 buckets per account with option to increase that limit to 1 million buckets I see no reason to use a bucket-per-tenant strategy.

Is it still best to use a prefix-per-tenant structure?

I've been doing some googling but struggling to find new information since most posts I find that suggest using prefix-per-tenant is from a few years ago or posted before the bucket quota increase.

I was hoping for at least one or two discussions around this but I am yet to find it. If anyone has some resources on this topic please share or if you have insight I would love to hear that too.

Thank you in advance :)
