5. Limitations of traditional WAN solutions

Enterprise network needs are rapidly changing
• Traffic is increasingly delivered to destinations
outside the enterprise network
• Coevolve data show 70-80% of MPLS traffic on
enterprise WANs destined for Internet –
combination of business-critical public cloud
traffic and web browsing
• 75% of Coevolve customers + prospects are
trialing or have rolled out Office 365 on a global
basis
• Innovative IT departments are moving IT
infrastructure to Azure and Amazon Web
Services at a rapid pace
• Business units often make decisions on
enterprise-wide applications without close
involvement from IT – Salesforce, Workday,
SuccessFactors, etc.

The problem with traditional WAN solutions
• High costs for routers, switches and WAN circuits particularly MPLS & WAN Optimization
• Backup capacity is wasted almost all of the time due to inflexible active / passive designs
• No seamless way to add capacity and availability using mobile, satellite, etc.
• Policy based Routing only provides limited route-based traffic redirection (not application-based)
• Never-ending demand for more bandwidth, regardless of geography
• New traffic flows are not well catered for – branch-cloud, branch-branch, DC-cloud
• Device-level configurations require highly skilled engineers, lots of opportunity for human error
• No concept of adding service layers to the network – only complex device-level configuration
The WAN is now one of the biggest obstacles to the agility and flexibility that enterprises require in their IT environments

8. SD-WAN as the foundation
for the next-generation WAN

9. © Coevolve Pty Limited 2015
SD-WAN: A new approach to network solution design
• To address the challenges associated with traditional networks, newer WAN products, services and designs
have emerged
• These are based on the concepts of Software Defined Networking and Network Function Virtualization
o Software Defined Networking (SDN) means separating the control plane of the network from the data
plane, allowing a centralized piece of software to assume responsibility for controlling the whole network.
Traditional approach: device level configurations
SDN approach: centralized software platform for network-wide orchestration and management
o Network Function Virtualization (NFV) means applying virtualization technologies to components of the
network to provide functionality in a pre-packaged form rather than building every component individually
• A primary goal of next-generation WANs is to deliver an enterprise grade network using primarily low-cost,
Internet-based infrastructure without the risks and complexities traditionally associated with this technology
• With the ongoing shift to public cloud applications and infrastructure, the next-generation network provides
seamless, controlled and measured connections to these destinations – far beyond the traditional split
tunneling / policy-based routing approach in current networks
• There are several new technology vendors competing in this SD-WAN space. Coevolve closely monitors the
available options and maintains a high level of technology and vendor awareness for its solution development
Some of the main technology vendors
in the growing SD-WAN space:

How can we articulate the TCO benefits of the next-generation WAN?

Traditional Network Next-Generation WAN
Procurement Implementation Steady State
Short-term cost
increase due to dual
running
30% savings
post implementation
50%+ savings due to
future bandwidth
increases
Short-term reduction in costs on
traditional network due to competitive
pressure at end of 3-5 year contract,
but increases due to bandwidth growth
Longer-term savings primarily due to
significantly greater bandwidth
available in next-generation WAN (and
not with 3-5 year contract lock-in)
Static, inflexible WAN Agile next-generation WAN

Out-of-the-box application performance visibility
• Next-generation WAN solutions such as the VeloCloud offering can classify
3,000+ applications and cloud services without the need to deploy separate
hardware or software probes in each branch location
• Self-learns new applications that are added to a cloud-based application
database
• Application aware business policy control for services such as Firewall,
Intelligent Multipath and Smart QoS
• Cloud scale analytics – self learning for intelligent circuit, gateway and path
selections including avoidance of network congestion points
• This application-level visibility allows reporting on user experience achieved
for each key application on the network using data-driven quality metrics

SD-WAN solves many problems – but creates a big one
Network agility &
elasticity
Quickly change traffic flows and application priority to meet
changing business requirements, with no device-level
configurations
Application visibility
SD-WAN solutions often include deep packet inspection to
classify applications; detailed analytics
Cloud application
performance
Increased use of public Internet connectivity provides a more
direct, high performance path to cloud services
Total available bandwidth
Internet infrastructure is usually sold in higher capacities, with
periodic upgrades of bandwidth unlike bandwidth-constrained
private IP networks
Network cost
TCO reductions of 50% or more are frequently seen by
migrating to SD-WAN solutions. Bandwidth costs and device
management overheads are reduced
Vendor Management
Increased use of Internet connectivity generally means more
ISPs to manage (commercially and operationally) and smaller
agreements mean less leverage

16. Addressing the
vendor management challenge

17. © Coevolve Pty Limited 2015
Coevolve’s approach to vendor management
• Significant team experience in the lifecycle management of 3rd party providers
• Flexible, modular managed service – can coexist with existing in-house management and augment capabilities to improve service levels
• Provide single point of contact for day to day management of locally-contracted services such as ISPs
• Letter of Agency established with each provider to enable Coevolve to act on client’s behalf
• Commercial and operational dashboards to provide a straightforward consolidated view across all ISPs
We have designed the Coevolve business from the ground up to be well suited to the
technical, commercial and operational management of third party ISPs and other local vendors

Vendor Management service does not impact SD-
WAN service; operates as normal
Single point of contact for client; Coevolve manages

18. Building the roadmap:
how do you get there?

19. © Coevolve Pty Limited 2015
Building a roadmap for the next-generation WAN
i. Identify an internal project
sponsor to help drive outcomes
ii. Identify industry peers that have
experience with the technology
iii. Identify high-level goals (TCO
savings, application performance
improvements)
iv. Identify non-core, risk free
elements of the environment to
trial the technology (back-up
links a great place to start)
v. Determine expectations and
steps for a trial or POC
1. Getting started
2. Understand where
the technology fits
i. Identify applications, locations and
user groups experiencing
performance issues
ii. Review the priority of the internal
and cloud-based application portfolio
iii. Review existing supplier contracts to
understand timeline flexibility
iv. Review capex investments –
determine end of life for existing
WAN Op, firewalls, routers, etc.
v. Update network architecture
documentation for clear
understanding
3. Prepare for transition
i. Update business case with revised
assumptions
ii. Develop detailed technical design
iii. Create an implementation roadmap
aligned to the understanding
developed in initial assessments
iv. Create a strategy document for the
technology team and business to
jointly understand
v. Develop communication plan for
regional / local IT and other
stakeholders
4. Implementation
i. This is not a traditional procurement
approach
ii. Do not look to enter into long term
(5 year) agreements – 24-36 months
maximum
iii. Simplifying the operational approach
will enable the IT team to keep an
eye on the horizon and work to
deliver business value rather than
struggle with operational challenges
iv. A phased migration will allow the
adoption of the new solution to be
aligned with existing contract end
dates
