This question is for anyone who has actually used Amazon EC2. I’m looking into what it would take to deploy a server there.
It looks like I can start in VirtualBox, setup my server and then export the image using the provided ec2-tools.
What gets tricky is if I actually want to make configuration changes to my running server, they will not be persistent.
I have some PHP code that I need to be able to deploy (and redeploy) to the system, so I was thinking that EBS would be a good choice there.
I have a massive amount of data that I need stored, but it just so happens that latency is not an issue, so I was thinking something like s3fs might work.
So my question is… What would you do? What does your configuration look like? What have been particular challenges that perhaps you didn’t see coming?
I recommend storing your PHP code in a repository such as SVN, and writing a script that checks the latest code out of the repository and redeploys it when you want to upgrade. You could also have this script run on instance startup so that you get the latest code whenever you spin up a new instance; saves on having to create a new AMI every time.
The main challenge that I didn’t see coming with EC2 is instance startup time – especially with Windows. Linux instances take 5 to 10 minutes to launch, but I’ve seen Windows instances take up to 40 minutes; this can be an issue if you want to do dynamic load balancing and start up new instances when your load increases.
