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.
