DIA remains the most popular way of accessing the cloud, but there has been a shift in deployment methods, according to a recent WAN Summit panel
Dedicated internet access (DIA) remains the most popular way
of accessing cloud infrastructure as a service providers,
according to a poll taken at the recent WAN Summit in New York,
with 43% of respondents picking it as their most common form in
a live poll of attendees.
It beat out Ethernet and IP VPN, while broadband gained less
than 5% of the vote, according to exclusive figures from
Most of the enterprises said they use a typical bandwidth of
between 1,000Mbps and 5000Mbps to private connections to their
cloud providers, with 101-999Mbps as the next most popular
option. Interestingly, around 12% of respondents said they used
connections surpassing 10,000Mbps.
The polls were conducted at the WAN Summit event, which is
ran by Capacity and TeleGeography, and featured a fascinating
panel looking at cloud services, with speakers from Oracle,
Microsoft, PacketFabric and enterprise Gate Gourmet.
Lloyd Noronha, head of SD-WAN marketing at Cisco, told the
gathered audience that he had seen a shift in how people deploy
their software-defined wide area networks in order to solve
problems with cloud services.
"We’ve seen more than 30,000 deployments of
SD-WAN solutions," he said, "but 90% of them were not related
to cloud." This, he added, began to change over the last year.
"In the last 12 months we’ve seen a dramatic shift
as companies want to use SD-WAN to solve a cloud problem."
Enterprise use cases
Microsoft, one of the leading cloud providers along with
Amazon Web Services, was also in attendance. Ross Ortega,
partner program manager for Azure networking at Microsoft, sat
on the panel, saying though the IT giant may not have been
traditionally seen as a networking company, this aspect has
become increasingly important as more companies have begun
using its cloud services.
"The growth of connectivity has been very strong," he said.
"Microsoft may not have been traditionally associated with
networking but we need a global backbone for all our
"It is common for people to do geo-dispersed and then start
using Microsoft for backup. We’re seeing growth in
private connectivity in APAC where the internet is not good
enough for most business critical applications. Latency breaks
applications so we have a private connectivity team for
"We designed our system so you can get to the cloud. Then
you need to think about what is the security model. That is now
migrating into the cloud at scale. We live this at Microsoft as
a big international enterprise and we deal with this balance:
what can be run in the cloud and what needs to be in lockdown,
To meet the needs of its customers, Microsoft "strives for
agility" and works closely with PacketFabric. He explained: "It
is really easy to spin up VPNs but it is hard ot manage them.
We work closely with PacketFabric to make sure we connect with
the PacketFabric routers. The physical network is still very
hard and clunky and anyone who works with it closely knows
that, but we’re working hard to hide that from the
Representing the enterprise view on the panel was Barry
Bonson-Bruce from Gate Gourmet, a catering company that
produces food for airlines. It is the world’s
largest independent airline catering, hospitality, and
logistics company, with over 28,000 employees operating
worldwide, highlighting the need for robust and far-reaching

have the opportunity to use public access – once you
put in firewalls, there is an opportunity to put in public
"You just want control of your customer data – you
can do analytics but at the end of the day you own that data.
Another product we have with ExpressRoutes is Ethernet which is
really cheap. They charge for that but there is value to
