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. eBay Platform As A Service(PaaS) uses it to deploy software to hundreds of thousands virtual machines. The state machine is also using for maintaining hundreds of thousands VMs and keeping them healthy.
####Case 1: Your job has multiple tasks that can be finished in couple seconds, so that you have to let something take care of it. Winder can do it in background.
####Case 2: You have bunch of items, each item needs to be processed in a couple of steps. Some of the steps can be guaranteed finishing in couple seconds. Winder can help you define the steps and let them work automatically.
####Case 3: You have some batch tasks, they should be executed every day. Winder can get this done easily.

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.
