Deploying Network Services in OpenStack
[Part 1: Challenges]

OpenStack Neutron provides multi-tenant aware configuration APIs for load balancer, firewall and VPN network services. The reference implementation renders these services on per tenant basis in router namespace on network node. A small subset of vendors have provided drivers to enable configuration of their devices using these common APIs. There are a number of challenges with deploying these services. As enterprises start deploying OpenStack in their production clouds, they find it very hard and frustrating to enable rich differentiated network services to their customers.

Network Service Configuration Simplified with GBP and NSD on ACI Fabric

Openstack Advanced Services in Neutron provides configuration APIs for Load Balancer, Firewall and VPN services. Configuration can also be automated using Heat templates. However, one of the challenges is the need to specify deployment variance such as network context to automate the provisioning of network services using templates. This becomes unmanageable and error prone in a large deployment. This blog explains how Openstack Group-Based Policy (GBP) Services framework addresses this challenge and how the One Convergence Network Services Delivery Platform (NSD) integrates with Cisco Application Centric Infrastructure to simplify lifecycle management of network services.
