VestaService 0.4.3

Code to facilitate creation of services and their integration to Vesta Service Gateway.

This package offers helper modules for Vesta services working in a distributed Service architecture. 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. Celery can be configured to run with various backends such as RabbitMQ or Reddis. It is mainly meant to work with the Vesta Service Gateway .

Requirements / installation

This package uses Python version 2.x.x but should be compatible with Py3K. Tox tests are run regurlarly through the TravisCI on github. See the tox.ini configuration file.
