Steps for a successful OpenStack PoC

St.Louis OpenStack Meetup October 2014 3

• Identify a team.

• Define the use case, scope & success criteria.

• Define Reference Architecture

• Define the criteria for comparing distributions

• Identity workloads.

• Define test cases.

• Execute PoC.

• Plan for moving from PoC to Production

Assemble a PoC Team

• Engineering/DevOps team with experience in

– Network

– Operating Systems

– Storage

– Python programming

• Project Co-ordination, Infrastructure sourcing

• Functional & Performance Testers

• Other Stakeholders

What is the use case?

Select backend solution

• Keystone – PAM, LDAP, SQL, KVS (Key Value Store)• Messaging – RabbitMQ, Qpid, 0MQ• Hypervisor – KVM, Hyper-V, ESXi, Xen• Network – ML2 (Modular Layer 2)

– Type Drivers (local, flat, VLAN, GRE, VXLAN)– Mechanism Drivers (Arista, Cisco, Hyper-V,

Linuxbridge, L2 Population, Open vSwitch)

• Cinder – JBOD(LVM), EMC, NetApp, Ceph, GlusterFS, Nexenta, HP, Hitachi, Fujitsu, SolidFire
