Architecture
The Savanna architecture consists of several components:
- Cluster Configuration Manager - all the business logic resides here
- Auth component - responsible for client authentication & authorization
- DAL - Data Access Layer, persists internal models in DB
- VM Provisioning - component responsible for communication with Nova and Glance
- Deployment Engine - pluggable mechanism responsible for deploying Hadoop on provisioned VMs;
existing management solutions like Apache Ambari and Cloudera Management Console could be utilized for that matter
- REST API - exposes Savanna functionality via REST
- Python Savanna Client - similar to other OpenStack components Savanna has its own python client
- Savanna pages - GUI for the Savanna is located on Horizon
