What is OpenStack?
•
OpenStack is an open source, Python based, cloud operating system. It is
designed to control large scale, multi tenant cloud deployments
•
OpenStack is built through a set of distributed services which control
compute, storage, network, identity management, orchestration, and much
more

Oracle Virtual Networking
High-speed, Converged Network Fabric for the Data Center
1)
Converged Infrastructure and I/O Consolidation
Solution
2)
Accelerates Applications and Optimizes Server to
Server Data Traffic
3)
“On-Demand” Network provisioning with Unified
Management enables a true “Cloud” Infrastructure
4)
Reduces Infrastructure Complexity by 70%

Oracle Virtual Networking
Oracle SDN: Software Defined Infrastructure
1)
Segregated L2 domains, called Private Virtual
Interconnects (PVI), across the 3-tiers
2)
Instantiate virtual network services “On-demand”
3)
Set Security and Policies between the 3-tiers
4)
“Policy Driven” and “Application Aware”
Templates using Unified Management

Accelerate and Scale your Openstack Deployments
•
Enable OpenStack to take advantage of Oracle SDN
–
Solve the VLAN exhaustion problem!!
–
True Multi tenancy with enhanced Security: Create Fully segregated L2 Networks
dynamically, not use VLANs for segregation.
–
High Speed: Created 40 Gbps NICs on demand in any of the servers!
–
Scalability: Create up to 16000 different L2 Networks on a single Fabric!
