Code to facilitate creation of Vesta Service Gateway.
This package offers helper modules for exposing services working in a distributed Service architecture through a REST interface. The work being executed by these services might be an annotation process or a form of conversion process taking a significant amount of time thereby benefiting from a distributed processing system with a REST interface.
Messages are communicated through a Celery distributed processing queue system.
This package offers basic functionality yet is meant to be wrapped by a higher level package which will offer a full application package.
Known examples of applications which use this package are:
- Vesta Load Balancer (alias Service Gateway or SG)
- Multimedia Storage System
