Network Functionality Virtualization is gaining huge traction in telco industry as it offers faster service enablement and cost savings in deploying Virtual Network Functions (VNFs). Telco providers have to meet service availability at 99.999% (Carrier-grade). Most of the VNFs are packaged and run on virtual machines. However containers with Kubernetes as orchestration engine is becoming more popular because of increased agility, reduced footprint and auto-scaling capabilities.

Though containers has become a viable alternative to virtual machines, there are significant gaps to meet carrier grade requirements for network functions in containers. This talk presents how to operate Kubernetes on OpenStack and provide the following key capabilities:

Multi-tenancy with resource guarantees
Multiple network interfaces which is a basic need for functions such as firewall
Data acceleration to give high throughput and low latency
Enhanced Platform Awareness such as SR-IOV, huge pages
