What this talk is NOT about…

• Continuous Integration and Continuous Deployment
• Automation techniques for Infrastructure, Deployment, and Operations
• Agile Development Practices

It’s an application architecture discussion

Architecture Design

Conventional App

• Monolithic
• Centralised state
• Tightly coupled
• Synchronous
• Single tenancy

Cloud-aware App

• Distributed,

Microservices

• Asynchronous
• Multi tenancy
• Failure-resilience
• Share-nothing
• Eventually consistent

Shift of Focus

Reliability = MTBF + MTTR + Availability

SHIFT

Traditional

Buy expensive hardware to increase MTBF Hardware-based redundancy

OpenStack Cloud

Maximise automation to reduce MTTR Software-based redundancy

12-Factor App

• Codebase: One codebase tracked in version control
• Dependencies: Explicitly declare and isolate dependencies
• Configuration: All configuration is stored in the environment
• Backing Services: Treat all backing services as attached services
• Build, Release, Run: Strictly separate build and run stages
• Processes: Execute the application as one or more stateless processes
• Port Binding: Export services via port binding
• Concurrency: Scale out via the process model
• Disposability: Maximize robustness with fast start-up and graceful shutdown
• Dev/Prod Parity: Keep development, staging, and production as similar as possible
• Logs: Treat logs as event streams
• Admin Processes: Run admin/management tasks as one-off processes

WordPress as a 12-Factor App

• Codebase: One codebase tracked in version control
• Dependencies: Composer and plug-ins listed in composer.json
• Configuration: Configuration needs consideration! What goes to the env and how?
• Backing Services: DBs, Queues, LB, SMTP, New Relic, API-services
• Build, Release, Run: Excellent stage to apply automation tools
• Processes: Stateless Processes means considering Sessions & Uploaded Files
• Port Binding: Port binding will require nginx+PHP-FPM, and some config work
• Concurrency: Consideration needed to avoid long-running PHP-FHM “daemon”
• Disposability: Mostly handled by PHP-FHM
• Dev/Prod Parity: Automate with VirtualBox/Vagrant & Puppet/Chef/Ansible
• Logs: Log files versus stdout … not quite
• Admin Processes: Even one-off processes are scripts and under version control
