Cheat sheet to create auto-scaling group behind ELB

  1. Create the appropriate VPC that your application is going to live in. Create subnets for each availability zone you want to use.

  2. Create VPC security group(s) for your auto-scaling instances. For example, if you're going to auto-scale web servers, create a "web" VPC security group.

  3. Go into AWS console and create an ELB. Easy wizard. Select HTTP and (if needed) HTTPS. Make sure it's associated with the VPC you created in step 1.

  4. Create an auto-scaling launch configuration from the CLI. The launch configuration has the AMI, size, and security group from step #2. The security group must be by ID not name ("sg-12345"):

       as-create-launch-config web --image-id ami-2e31bf1e --instance-type m1.medium \

-g sg-7619041a --key root

Nginx sample config for EC2

# Sample nginx.conf optimized for EC2 c1.medium to xlarge instances.
# Also look at the haproxy.conf file for how the backend is balanced.

S3 file hashing scheme for linear distribution
#!/bin/sh
# Get crazy throughput if you do this (>5000 puts/sec)
#
# What some customers have done is something like this: say this is the filename:
#
# mybucket/17476/26466/16.png
#
# Then to get the hash do something that seems silly but works great (pretty
# much any two characters from the hash will work):
