Hosting a subversion server on an Amazon EC2 instance

After I have my EC2 account set up, Launch Instance

I choose Windows 2008 R2 Server. 

I go to Add Storage because I know that 30 gigs is going to get used up quick (almost 20 of it starts out used by the OS, etcetera). This will cost some money, but so far I've paid less than a dollar a month.

I confirm and Launch.

I generate the Key Pair.

I right click on the instance once it's running and Get Windows Password.

THIS TIME, I'm saving my Key Pair and Password someplace safe. :P

I connect with Remote Desktop and find that I can't seem to download SVN or anything.

So I go to Server Manager->Server Summary->Security Information->Configure IE ESC and turn that shit off for Administrators, whatever it is.

Okay, I can download stuff now. This time I'm going to be better than last time, I'm going to use VisualSVN Server, which has more security! 

I manage to set up a test repo, (using https: and port 443) and I can connect to it from the Server, but not from anywhere else. Do I have the port wrong? The address? Firewall problems? Who knows!

Eventually I figure out to go to the EC2 Management Console->Security Groups->the group for my new instance, and add rules not only for TCP port 443 but also ICMP, so I can just Ping the darn thing and make sure I see it at all. (After I add the rule I have to remember to Apply Rule Changes.)

Now things seem to work from the client side. I can
svn ls https://my-public-ip-here:443/svn/happionlabs 
and see my test repo. (There was a moment of hilarity, because in trying to figure out what was wrong I turned off the https: security on the server side, which changed the port to 80 without me noticing, so I couldn't figure out why, now that I'd figured out how to open the freaking ports, things still didn't work. Haha. Ha.)
