1. EVOLVING THE WAN FOR THE
CLOUD, USING SD-WAN & NFV
Carl Kotze
Senior Manager, EDP Product Specialist, Interoute

2. Key Topics
Evolving the WAN for the Cloud, using SD-WAN & NFV
What is SD-WAN &NFV
Benefits of NFV and SD-WAN for application centric networks
Real-world implementations
Virtualization and other trends

3. Traditional WAN

8. Cloud Adoption
WAN for the cloud age
As applications move to the cloud,
traffic can take an indirect route,
resulting in poor performance.
Traditional networks were designed to
deliver applications from a central data
centre, with low latency from each site.

Above a certain value, increasing
bandwidth has little impact on
improving application
performance.
Reducing latency has a significant
impact on improving application
performance.

Cloud Latency Challenges
Lower latency, faster applications
Typical latency
for cloud fabric
connections
80 ms
Typical latency for
local ISP
connections
160+ ms
Cloud fabric delivers lower latency
connections and higher throughput.
Vast majority of cloud applications delivered
from the USA, with high latency.
*Based on Interoute ISP network latency data and Mike Belshe. Google white
paper. “More bandwidth doesn’t matter (much)”
Cloud applications are 2x faster than many
ISP services*.

25. Key takeaways
The WAN is evolving from an infrastructure focus to an
application-centric design to take advantage of cloud
based services.
Reliable and manageable latency is essential for
reliable applications. Using “any internet connection”
comes with significant risks.
An SD-WAN strategy needs robust security at the
network edge and often benefits from WAN
optimisation. Together this is well suited to virtualised
x86 based CPE.
