[...] Amazon launches virtual private clouds « RightScale Blog"Something that initially puzzled me is what the benefits of a VPC are when all the marketing fluff dissipates. Here is what I’ve learned. First, instances in the VPC are separated from non-VPC instances at a deeper network level than instances in different security groups or belonging to different users. As is typical, Amazon doesn’t say anything of substance about the nature of this isolation. Let’s see how soon that will have to change to actually attract enterprises… Second, instances in the VPC can seamlessly integrate into a company’s internal network routing. This is significant because it means that tools used to inventory, secure, audit, manage, and access all servers in the IT infrastructure can now be brought to bear on instances in the cloud as well."

Daniel, good question. I haven’t heard anything in this respect and I would assume ‘no’, but I’m sure a forum post can resolve that.

Do you know if EC2 instances running as part of a VPC support multicast traffic?

Carson, due to NDA issues I can’t say more about the network isolation, but the truth is that I actually don’t have much more information. The isolation is better in that arbitrary regular instances can address each other and routes to each other exist and isolation is really governed by the security groups, which is a layer 3 firewall type of thing. Instances in different VPCs can’t address each other and there are no routes.
Your statement that this isn’t going to be enough is both true and false. You have to remember that it’s a spectrum. With the VPC a whole lot more become eligible to move to the cloud, so to speak. Will everything move to the cloud? No. Read Werner’s blog, he doesn’t expect 100% conversion either (well, I’m sure he’s targeting it down the road). One thing we don’t know is what he’s saying about the engineering and processes being applied to their infrastructure when he is talking to “a large financial services company in the Northeast”. In our public musings we may be underestimating the percentage of the workload that can be moved because we don’t have the full picture.

Can you say more about how or what you learned about the network separation? In technical terms is it something like them creating a VLAN for you? The phrase you use is a little confusing, I believe you are talking about separation at just the network level right?

I don’t think this is going to be enough to move people who currently have a true security concern into the cloud. Ultimately it may be impossible without physical machine separation. There will always be questions about leaking information between virtual machine instances through hypervisor bugs. It seems reasonable that for more cost this could be the next step for Amazon.

[...] Amazon launches virtual private clouds « RightScale Blog – This evening Amazon launched a new service called “VPC”, which stands for Virtual Private Cloud, read the details on the product page and the AWS blog, plus a nice backgrounder on Werner Vogel’s blog. The short story is that it allows anyone to spin up a private enclave within Amazon’s infrastructure. This allows VPC users to segregate their EC2 instances from “the masses” and get a VPN connection from their own data center to their VPC, which then looks like a part of their internal network. Exciting stuff and we’ll have support for VPCs in RightScale real soon. [...]
