Re: EC2 Dedicated Hosts

Man, I'd really like to just see bare metal from them. To me that was part of the allure of containers -- so much more efficient than multiple VMs and yet you get a lot of similar benefits, as long as you don't mind some security tradeoffs. Running ECS is cool and all, and I know they do some container-specific VM optimizations, but I still know I'm running a kernel on a kernel, even if my VMs happen to share a host.…

I'm sure Amazon would love it too (think about how much money they could save / make) but there are a lot of security concerns that need to be addressed. Running code in a virtualized kernel is a lot more secure than running in the real kernel with permissions limited. Theoretically an exploit could allow someone to take over the machine, whereas if the machine is virtualized it's much harder to take over the host.

Doesn't matter if the machine is taken over if its properly contained at the network level. Dedicated server hosting companies have been doing this for years.

Can anyone give me the advantages of choosing an EC2 dedicated host over going with a true dedicated server?

It's called Amazon. Other cloud services and bare metal hosts are not called Amazon.

Thanks to the amazing innovation at Amazon, 2016 will be the year, we can finally have a real computer in a datacenter, where we can run all our JavaScript code on, instead of of having to use an anonymous cloud service.

This isn't even bare metal. This is just pinning or affinity. (Pinning, or affinity, depending on host failure mode - do they failover to a new host, and do they all get to be on the same host again?)

Sure, your jobs aren't fighting another customer's jobs for CPU; now you're fighting your own jobs for CPU.

Earlier quoted context omitted.

Their example dedicated host adds up to $2'226 per month - had a quick calc on the retail HW cost for a machine like this - should not be more than $6.5k with 2 * E5-2670 v3 12 cores. What I understand so far - it is physically bundling a fixed amount of virtual machines to a physical host - in the example "dedicated host" 22 * m4.large. Bundling your virtual machine to one or a series of physical hosts / on the same…

What if the license of the software you want to run is 100k per physical host? Then being able to run 2 or 4 instances on the same physical host makes the $2226 cost pretty insignificant.

If you have software that costs that much, you will want to run it on hardware optimized for that software. (Does it want lots of GPU cores? I/O? Raw computrons? Does it prefer more cores or more GHz/core?) Unless Amazon happens to have exactly what you want available, you'll be better off putting it in a lab or datacenter.

Maybe we could distribute the computing on these dedicated hosts, to have like, virtual dedicated hosts. And then run them from Minecraft... It's the future.

With VMs the customer can share a physical host with others and not have security concerns. This cohosting lets aws pack customers more efficiently and have much better margins for the same quality service.

With containers on bare metal, they could not cohost customers.

All the advantages of a dedicated server without the hassle of saving tons of money.

Many of our customers have asked for this feature so that they can run software that is licensed for a particular piece of actual hardware.

To think of it another way, smaller companies might save money by buying bare metal and renting colo space. But larger companies would spend more just managing the separate bill for the colo, not to mention the logistics of another datacenter.

Are there any good, dependable, modern alternatives if you don't want to deal with the hardware, and also don't need "scale on demand"? The only name I know is SoftLayer, which is certainly not cheap.

You can implement the HTTP parse logic in Minecraft using redstone. Deploy nginx or Apache Traffic Server in front of your Minecraft and you are good.
