The Sahara architecture consists of several components:
|
|
|
|
* Auth component - responsible for client authentication & authorization, communicates with Keystone
|
|
|
|
* DAL - Data Access Layer, persists internal models in DB
|
|
|
|
* Provisioning Engine - component responsible for communication with Nova, Heat, Cinder and Glance
|
|
|
|
* Vendor Plugins - pluggable mechanism responsible for configuring and launching Hadoop on provisioned VMs;
|
|
existing management solutions like Apache Ambari and Cloudera Management Console could be utilized for that matter
|
|
|
|
* EDP - :doc:`../userdoc/edp` responsible for scheduling and managing Hadoop jobs on clusters provisioned by Sahara
|
|
|
|
* REST API - exposes Sahara functionality via REST
|
|
|
|
* Python Sahara Client - similar to other OpenStack components Sahara has its own python client
|
|
|
|
* Sahara pages - GUI for the Sahara is located on Horizon
