Zoe - Container-based Analytics as a Service
============================================
Zoe provides a simple way to provision data analytics clusters and
workflows using container-based (Docker) virtualization. The guiding
principles are:
- ease of use: data scientists know about data and applications,
systems and resource constraints should be kept out of the way
- ease of administration: we have a strong background in systems and
network administration, so we put all effort possible to make Zoe
easy to install and maintain
- use well-known technologies: we try hard not to reinvent the wheel,
we use Python, ZeroMQ, Docker and DNS
- a clear roadmap: our short and long-term objectives should always be
clear and well defined
- openness: the source code is open: clone, modify, discuss, test and
contribute, you are welcome!
Zoe provides a simple way to provision data analytics applications using Docker Swarm.
This is the main repository, it contains the documentation and a number of scripts, useful to install and develop Zoe.
We are in the process of updating documentation and scripts. For now you can refer to the version tagged 0.8.92 in this repository,
when all components where still together.
Resources:
- Documentation: http://zoe-analytics.readthedocs.org/
- Docker images:
https://github.com/DistributedSystemsGroup/zoe-docker-images
- Main website: http://zoe-analytics.eu
- Documentation: http://docs.zoe-analytics.eu
- How to install: http://zoe-analytics.readthedocs.org/en/latest/install.html
Zoe is a distributed application and each component is developed in a separate Git repository.
- Zoe clients: https://github.com/DistributedSystemsGroup/zoe-client
- Zoe scheduler: https://github.com/DistributedSystemsGroup/zoe-scheduler
- Zoe object storage: https://github.com/DistributedSystemsGroup/zoe-object-storage
Zoe can use any Docker image, but we provide some for the preconfigured applications available in the web interface:
