BIG DATAINTERNET OF
THINGSSHIFT TO THE
CLOUDMOBILITY
Gartner forecasts that 6.4 billion connected
things will be in use worldwide in 2016, up 30
percent from 2015, and will reach 20.8 billion
by 2020
Worldwide revenues from public cloud
services will reach more than $195 billion in
2020. This will be more than double 2016
revenues and represents a CAGR of 20.4%

our customers are facing a new set of challenges
7
Need for
higher
bandwidth
Customer demand has a strong growth:
WAN bandwidth requirements are
increasing above 30% per annum every
year
Customers can set up new cloud services in minutes, yet delivery
times for new VPN sites and Ethernet connections are still
measured in weeks and months.
Radically faster
network
delivery
Need for more
in-life agility
Cost efficient
scaling
Cloud services can be scaled up and down on demand, while
bandwidth upgrades and feature changes for the network are
traditionally manually requested and take days/weeks to deliver
Since 65% of WAN budgets are flat or declining, cost efficient
scaling of bandwidth is crucial.
“With a progressive uptake of video, IP audio and cloud, the compoundannual growth rate (CAGR) of IP traffic is above 30% per year”
In response to this we are…

Investing in a new ultra-high bandwidth network
Introducing a high bandwidth optimised portfolio
Launching On Demand and Software Defined WAN Services
Further increasing focus on Enterprise market
Investment in ultra-high bandwidth “IQ” network: 4 focus areas
Build an Integrated Core and
Metro Packet Network
• Single integrated IP and
Ethernet core network,
covering 200+ data centres
across Europe and Asia
• Delivers 100Mbps to 100Gbps
services via plug and play
model
4 key investments will transform the backbone networks that support our
customer services
• New metro optical network
across 90+ data centres in 13
key cities in Europe and Asia
• Off the shelf delivery of
100Gbps & 200Gbps waves
• Rapid leadtimes – 5 days for
10Gbps waves
High bandwidth optical network
between major data centres
Evolve our voice network
New optical backbone:
“Express” Long Distance Network
• Next generation SIP Trunking
session board controller
• SIP Trunking coverage expansion
to
21 countries
1
• Build “Express” long haul
network between 30 major
European cities
• Based on architecture optimised
for high bandwidth
connectivity

Novitas what is the customer need?
Today’s digital economy means our customers can:
Place an order, and it is delivered the next day
Book a taxi via an app, it turns up in minutes
However, most telecom services are still ordered and delivered in the same way they were 20 years ago!
Order cloud IT services and it is delivered in
seconds
11
Novitas what does it mean?
12
NOVITAS transforms the way that network services are ordered and consumed, and brings a cloud like customer experience
Delivery in weeks
Manual configuration
Steep bandwidth vs cost curve
Traditional telco experience

Ethernet on demand (learnings)
Product/sales innovation required (new commercial model)
Full leadership support a must
Equal priority to API and Portal/GUI
Agile development requires internal alignment & agreements
Commercial APIs (NB & SB) not 100% mature
IT development trade offs (java vs cloud)
Effective automation requires a clean inventory
OPS transformation is paramount
18
SD WAN on demand (enterprise challenges)
More Bandwidth
Flexible Traffic PatternsNeed to increase Agility
Bandwidth requirements increase by
20 – 30% per y ear
while
65% of WAN budgets
are Flat to Declining
Implementing changes(portal driv en, not off-line process)
Adding a new branch site(in hours, not weeks)
Upgrading bandwidth(instantaneous, not days)
Public Cloud impacts WAN traffic patterns
• WAN “break-out” to public Internet no more
centrally , but close touser, e.g. SalesForcetraf fic at customer site
• Need f or Firewall
f unctionality and network-wide policy

CostDelivered using competitively priced public Internet
services, meaning only high priority traffic is routed
across premium MPLS paths.
ResilienceEither network path (MPLS or Internet) can be used
as backup in the event of a failure.
Speed of deliveryUsing customer’s existing Internet Access enables a
much quicker service deployment than OLO tails.
Multi function
CPE
X86 architecture means that one CPE can act as a
router, firewall, or application performance monitor
via a single device.
