First AstriCon - 2004
I
The future of communications runs
on the future of computing
infrastructure.
Key point #1:
Cloud is the future of both
public and private
computing infrastructure.

Virtualization - Consolidation
Cloud - Agility
Agile Infrastructure
●Self service
●On demand
●API driven infrastructure
Agility for your business
●More efficient teams
●Pay as you go
●Pay for consumption, not capacity
Who uses this stuff?
●This is old news for web companies.
●Moving into enterprise data centers globally and being used for
all types of workloads.
●Even telcos are moving to cloud infrastructure.
NFV - Network Function Virtualization
●Major shift in telco equipment industry over the last few years
●Goal: take expensive, inflexible hardware appliances and turn
them into VMs running on cloud infrastructure.
●Deliver new services in a matter of days, not months
NFV Timeline
●NFV white paper - October, 2012
●2014 -oOPNFV (Open Platform for NFV) launched by Linux Foundation to
develop an open reference platform
oTelcos and NEPs (Network Equipment Providers) doing POCs
●2015 oProduction deployments expected
NFV - Open Source Building Blocks
Key point #2:
Openness still matters.
How has openness impacted the
success of Asterisk and other
communications platforms?
Interoperability
Open Cloud
Mission: to produce the ubiquitous Open Source Cloud
Computing platform that will meet the needs of public and
private clouds regardless of size, by being simple to
implement and massively scalable.

Give OpenStack a try!
●RDO - community OpenStack distributionohttps://openstack.redhat.com/
●OpenStack based public cloudsohttp://www.openstack.org/marketplace/public-clouds/
Key point #3:
Make your apps cloud aware.
Scaling in Cloud
●Horizontal scaling
●Auto-scaling based on load (using Heat)
●Design for failure
CPU and Memory Performance
●Beware of overcommit.
●Requirements from NFV use casesoNUMA awareness
oDedicated CPUs
oDedicated memory (large pages)
Network Performance
●Data plane applications want network performance as close to
bare metal as possible
●Requirements from NFV use cases:oSupport for SR-IOV network devices
oIntel DPDK enablement
Consider your storage options
●Ephemeral local block storage
●Persistent block storage (Cinder)
●Relational database service (Trove)
●Object Storage (Swift)
Recap
The future of communications runs
on the future of computing
infrastructure.
Key Points
●Cloud is the future of both public and private computing
infrastructure.
●Openness still matters.
●Make your apps cloud aware.
