Intertwined with this announcement of an new instance type, is that it uses a non-Xen hypervisor.<p>Has anyone booted one yet? Is it KVM or something from scratch that AWS wrote?
No pricing info on c5 or whether c4 has changed in either the blog post or <a href="https://aws.amazon.com/ec2/pricing/on-demand" rel="nofollow">https://aws.amazon.com/ec2/pricing/on-demand</a>
Interesting that Amazon is charging less for Skylake than Broadwell while the list prices for Skylake are higher. I guess Intel really wants you to move to the cloud.
I'm a little bit surprised that Amazon are mapping vCPUs to HyperThreads, instead of to cores. It seems to me like, if this is targeted at compute-intensive workloads, that it may be overcommitting a bit. Or is there recent research saying that an HT thread is equivalent to a core for compute-intensive workloads?
> These instances designed for compute-heavy applications like [...], highly scalable multiplayer gaming<p>Is he referring to specific titles? It's been a while, but to me, the max lobby size for multiplayer games was stuck at ~70 concurrent players (sending all updates to everyone is n^2).
I'm tired of updating my CloudFormation templates with the new instance types every month.<p>Can AWS provide CFN template with all valid instance types, that I can import in a CFN?<p>Maybe some other programmatic way as an API or CLI, i.e.:<p><pre><code> aws ec2 describe-instance-types</code></pre>
