At the OpenStack Summit today, Rackspace announced it's new Performance Cloud Servers. They are completely SSD and boast significant performance benchmarks. However, lots of developers are noting that although their pricing beats Amazon's in SSD cloud infrastructure, Linode and Digital Ocean have Rackspace beat on price.
I wonder whether this move from Rackspace was significantly influenced by Digital Ocean's meteoric rise with it's low-priced pure-SSD servers. I think the other vendors have to be taking notice of the scrappy startup by now.
The new Performance Cloud Servers do show the versatility of OpenStack, which they are based on.
