Multi-tenant RuBAN on Openstack

Owned by Colin Ryan
Last updated: Jan 23, 2017

Openstack Prerequisites:

The following components of Openstack need to be available to install RuBAN:

  • Heat
  • Nova
  • Neutron
  • Cinder
  • Swift
  • Glance
  • Keystone

RuBAN uses these apis both via the Openstack client utilities and as REST Calls so the api url must be reachable from the internet and from the internal network the nova compute instances run on.

Cluster Sizing

On initial rollout RuBAN will create a heat stack with :

A dedicated network with a route to the internet, this consumes one Floating IP

1 Master Node: 2GB RAM and 2 Cores and one Floating IP

3 Minion Nodes: 16GB RAM and 8 Cores

Shared Components

Kafka - 50GB Cinder Volume. All data uploaded from IoT devices is first placed onto a kafka topic to be processed before storage and forwarded onto down-stream components.

Zookeeper - 50GB Cinder Volume. 

MongoDB - 50GB Cinder Volume

Postgresql DB - 50GB Cinder Volume

Cassandra - 200GB Cinder Volume

Loading

The above setup has been tested against 500 IoT devices, divided among tenants sending 1 data point per minute.
