Nearly all the "second tier" clouds support IPv6: Digital Ocean, Vultr, Linode, SoftLayer, etc.

AWS's services are great but many people just need compute. I don't understand why people who just need compute use AWS, since for compute only Digital Ocean and Vultr destroy it in virtually every way: ease of use, performance, cost, IPv6, etc.

Digital Ocean now has block storage too, which plugs one hole. Of course they don't have things like RedShift or S3, but like I said not everyone needs that.
