This tutorial walks through setting up AWS infrastructure for WordPress, starting at creating an AWS account. We'll manually provision a single EC2 instance (i.e an AWS virtual machine) to run WordPress using Nginx, PHP-FPM, and MySQL.
This tutorial assumes you're relatively comfortable on the command line and editing system configuration files. It is intended for folks who want a high-level of control and understanding of their infrastructure. It will take about half an hour if you don't Google away at some point.
If you experience any difficulties or have any feedback, leave a comment. 🐬
Coming soon: I'll write another tutorial on a high availability setup for WordPress on AWS, including load-balancing multiple application servers in an auto-scaling group and utilizing RDS.

This script performs efficient concatenation of files stored in S3. Given a | |
folder, output location, and optional suffix, all files with the given suffix | |
will be concatenated into one file stored in the output location. | |
Concatenation is performed within S3 when possible, falling back to local | |
operations when necessary. | |
Run `python combineS3Files.py -h` for more info. | |
