My Systems Architecture diagram as presented at the Tampa Java Users Group “Let’s Talk Stack!” night.
Every time I fire up a new EC2 instance, I inevitably forget to configure swap memory for it (why don’t they just come pre-configured?) only to realize it later when some application experiences sudden death at the hands of a (shriek!) OutOfMemoryError. I’ve gotten pretty quick at configuring this, and thought I’d share the recipe.
The following instructions are for an EC2 instance running Amazon Linux (which is basically CentOS). They will probably work for any RedHat-based distro.
Amazon Web Services has made SSD the default storage type for its EBS volumes and it’s actually pretty cheap. However, to take advantage of this, you’ll need to migrate your production storage volumes to SSD.
