Storytella[0] is running on AWS. Currently I'm trying to keep costs down so everything is running on micro instances which are free for 12 months for new sign ups. I have set up:
EC2 micro instance running a django application EC2 micro instance running CouchDB RDS micro instance running MySQL ElastiCache micro instance running Redis S3 storage for user images 1 Lambda function for resizing images
That set up is handling roughly 1200 sessions per month at the moment and costs me roughly $15 per month, which is mainly for the second EC2 instance. If I was paying for everything it would be more like:
EC2 instances x2: $15 RDS: $25 ElastiCache: $12
The S3 and Lambda services are a bit more tricky to work it and I'll worry about it when I need to. For everything else it's roughly 750 hours per month x hourly cost.
If you've got any follow up questions let me know.
