Winder is a simple state machine based on Quartz Scheduler.
It helps to write multiple steps tasks on Quartz Scheduler. Winder derived from a state machine which is widly used in eBay Cloud.

Winder can help you define the steps and let them work automatically.

####Case 3:

Plan

Refine the code to use femto-coin to manage its components

Production use cases

Production Use Cases: widely used in many distributed systems which eBay Cloud relies on.

Software Deployment/PaaS: As the key part of eBay Cloud, Platform As A Service(PaaS) is widely used in eBay. Developer uses it to roll out code. Winder takes the key role in PaaS.

Virtual machine maintenance: eBay has hundreds of thousands VMs. Keeping them healthy and available is very important. Winder makes this possible.

Provisioning container or VM: Provisioning requires lots of communications with other systems. It is also built on Winder.
