I am using DHCP to assign primary IP addresses in a subnet within Amazon Web Services EC2

To avoid issues where the boxes are rebooted and the DHCP address changes, I have assigned a secondary IP to the NIC in the same subnet which is static and I reference those in the configuration files.

Although this has worked for months, this seems a little dirty - is there an SDL or community recommended way to configure the relevant Tridion components?

In my AWS options I have access to 4 "Elastic IPs" that I can assign to any of my instances. This - I guess - is an option we have in the contract with AWS, not sure how/why I have this :)

These are static, public IPs that I can use and re-allocate at any time to point to any of my machines, and didn't have trouble with this so far.

    this is fine for public instances, but not so good for securing (for example) a database or app server. You're really supposed to use a VPC/NAT for "internal" boxes with non-addressable subnets. It feels like a scriptable templated solution involving Chef and some sort of DNS would be a way forward but as usual with AWS there's 100 ways to skin the proverbial cat.

    Fair enough, didn't think of the "non-public" parts of it. You may want to try your luck on a more generic infra forum...

    @mpaton I think Nuno makes a valid point here, even though your question is in essense related to Tridion and tyou might get a valid answer from the community here, it can also be seen as a generic AWS issue: "how do I get my database and application server to keep communicating after reboots when they have a DHCP assigned IP". Posting it in serverfault.com will probabaly give you a much better response.
