This document discusses scaling WordPress on AWS. It introduces AWS services like EC2, EFS, S3, RDS that can be used to deploy and scale a WordPress site. It explains different scaling approaches like vertical scaling by adding more resources, horizontal scaling by adding more machines, and global scaling across availability zones. An enhanced WordPress architecture using EC2 for the frontend and logic layers, RDS for the database, and S3 for file storage is proposed. Core and additional AWS services for development, operations, security and more that can help scale WordPress are also outlined.

AWS ?

5. Why scaling?
• varying number of posts/pages/products/…
• varying number of sites and users
• varying number of hits and visits
• availability in different global areas
• different compliance and data residency requirements

6. Examples
• slashdotting
• promotion campains
• seasonal business
• DDoS

7. • just extend the machine!
• more CPU
• more RAM
• more Bandwidth
• more Storage
