Working Example
• What can we learn?
• The cron checks to see if it is already running
• We should monitor this going forward
• Look for any errors in table or logs
• If it is a heavy install could use Aoe_Scheduler

• More modern best practices
• Better methods to change system behaviour in a
more targeted way
• Code should be more decoupled which should
help reduce bugs during upgrades
• New architecture makes automated testing easier
