Keep in mind that the memory usage you're seeing is most likely the total heap, and not the actual memory being used by Railo. Railo 3.3 has some nice visualizations built into the administrator that should show you the percentage of the heap actively being used. In terms of attacks, I'd suggest following general best practices and security precautions. I'd imagine you'd face the same sorts of attacks regardless of where you are hosting, although a single micro instance might be more vulnerable to DDOS attacks because of the way it throttles CPU. In any case, this probably isn't the best forum to discuss it. Memory can definitely be a limiting factor when using a micro instance.

I am currently using the micro instance as well and I am little worried about the 600 MB (not sure of the exact number) of memory. Did you face any memory issue. I don't expect a lot of traffic, but during testing when I did ps -aux and free -m I see almost 90% of the memory is used. I am very new to this, so if you have any experience please share. Also did you get any attacks (specifically W00T attacks)?. I just launched my site a week back and I am already getting hit, making my bandwidth go up and causing more money for the put and get request. Also if you have Any Railo specific security handling tips please share. Thanks, Raj Thank you for sharing this.

Installing Railo on EC2 with Amazon Linux
installing railo on ubuntu on amazon ec2 with ebs volumes

Something else to note: when I’ve created instances in the past, I usually install everything on a small instance then create an AMI and restart as a micro. I’ve had problems in the past installing on a micro as it gets throttled easily and has a tendency to hang.

It's a great option, especially because it removes the reliance on an external build tool. I recently started using cfStatic for a couple projects I’m working on.

I'm definately going to have to have a play with the free usage tier. Thanks.

Using a ftp client that supports sftp is probably the easiest way to get up and running if you're used to deploying via ftp. Amazon also offers their "AWS Elastic Beanstalk" product which is their PAAS product and sounds like it's similar to Jelastic, might be worth evaluating if you're headed down that path.

I'm interested in how you deploy to EC2; do you just create a WAR file with everything in it, or do you upload files via SSH? I've been looking at Jelastic recently as an great and easy way to deploy to cloud and sace horizonally on demand. Interesting post Mike – I’m currently reading up on using Amazon for hosting.

]]> Comment on Memory Leaks: Part II – variables scope leak by mike http://www.schierberl.com/blog/memory-leaks-part-ii-variables-scope-leak/#comment-795 mike Tue, 11 Oct 2011 17:33:34 +0000 #comment-795 It's been a few years since I've looked at this, but I do remember that the behavior described in the post was addressed and fixed with one of the ACF 8 updaters. However, the updater did not fix the problems that we had observed in our production environment at Planitax. I also recall that the problem was limited to ACF, and did not appear in BD or Railo, unfortunately at the time those platforms weren't options that we could have considered.
