comment When to chose hardware accelerated crypto for Big Data
@RichieFrame Do you have a cite for that? My understanding is that NSA got it between datacenters. I agree, from a trust boundary point of view, you need to be careful in that respect.

comment When to chose hardware accelerated crypto for Big Data
The problem I'm faced with is what ciphers customers should support from a client base when loading a cloud based hadoop cluster. Also, how should the hadoop cluster store data at rest. My feeling right now is that we should not have encryption for data in transit in the cloud based cluster itself. Thoughts?

@MaartenBodewes Thanks. I looked up HSM and I read that they were really just for things like accelerated RSA. My assumption is that server CPUs are usually good for AES256 acceleration.

Thanks @Demetri. Mostly I'm assuming that client and server both have modern hardware (loading Hadoop cluste). My assumption at this point is that modern Intel CPUs all have AES hardware acceleration. Is this the right assumption?

It's a fair point. I'll change the accepted answer. The standards were (are?) messed up.
