This doesn't say what minio actually is. It also says the benchmark cost $1000 to run. Also since this is terabits it is about 120 gigabytes per second using 256 drives.
I looked up the pricing: Each i3en.24xlarge (96 vCPU, 768GB RAM, 8 x 7500 NVMe SSD) costs $10.848 per hour. For the test they rented 32, so around 350 USD/hour or around 250.000 USD/month.
At this cost, is AWS really worth it? Shouldn't colocation be much cheaper after only a few months of use?
Minio is an s3 interface compatible storage api.
whats the use case?
A self hosted alternative to s3, a scalable object store service.
Isn't that just called a file system?
S3 is block/object storage, not file or filesystem.
