### Operations

---
# Magento 2 operations
- No code generation of live server
    - Not running `magento setup:di:compile`
    - Committing `var/generation` and `var/di` to git?

---
# Magento 2 operations
- No code generation of live server
- No composer updates on live server
    - Committing `composer.lock` to git (?)
    - Use `prestissimo` for faster downloads
    - Use Satis or Toran Proxy for offloading
    - Optimize autoload file (`--optimize-autoloader`)

---
# Magento 2 operations
- No code generation of live server
- No composer updates on live server
- Interceptors instead of event observers
    - Interceptor count matters less due to code generation
    - Count of dispatched events does matter
    - But events are less confusing than interceptors
