OpenStack hardware architecture for running HDP

avatar
New Contributor

Hello all,

I'm planning to have my own private cloud using OpenStack. I've already seen some sample architectures to do so, like the following one: http://docs.openstack.org/openstack-ops/content/example_architecture.html

My ideas is to have a regular private cloud but also capable to run HDP efficiently.

My question then is the next one: Which architecture should I use in order to run a HDP in my OpenStack cloud? There is any architecture sample out there to achieve that?

My guess is about having 4 compute nodes (with enough RAM, CPU and local storage, Cinder, to run many VMs as Hadoop nodes), 1 controller node (API services, high availability services, Neutron) and 1 Swift node (for all storage but Hadoop nodes storage).

What do you think about this possible architecture? Does it make sense?

Thanks!

Do you think having just 1 controller node is enough? This node will run Neutron, OpenStack components API services, OS and some monitoring staff as well.

Yes 1 controller is enough. Because you don't have big environment. I am running with same configuration 4 compute node 1 controller and I don't see any issues to monitor openstack components.

For a size like this is fine - you can check these Ansible scripts in order to set up an OpenStack, than use Cloudbreak.
