I tend to agree :). If we get 1 req/s, even for a dataset of that size, this is not as cost efficient.

For that kind of use case, I'd probably start using minio.

Don't forget S3 includes replication. Also EBS throughput (even with SSD) is not good at all. Also our memory footprint is tiny. This is necessary to make it run on two servers.

Finally, cpu-wise, our search engine is almost 2x faster than lucene.

If you don't believe us, try to replicate our demo on an elastic search :D.

Chatnoir.eu is the only other common crawl cluster we know of. It consists of 120 nodes.
