How SD-WAN Helps

Automatic application recognition and categorization

Services catalog & network services insertion (on-premise, cloud)

Dynamic path steering & on-demand remediation

1. Getting started 2. Assess technology fit

3. Prepare for transition 4. Implementation

• Identify a project sponsor

• Establish high-level project goals

• Identify portions of environment to trial technology

• Identify “low hanging fruit” to prioritize

• Test technology in POC environment

• Identify challenging applications, traffic flows, user groups

• Review existing vendor contracts

• Identify priority of major global applications

• Build and maintain business case for transition

• Develop profiles / templates for each site type

• Build implementation roadmap

• Build communication plan for stakeholders

• Phased migration in line with contract expiration dates

• Rollout of additional Internet infrastructure as needed

• “As a service” model means low/no capex

• Identify new focus areas for ops teams

How a Retailer Got Started

• Hybrid branch with hosted VOIP• Unreliable MPLS had packet loss then ~20 minute

outage

• Cable simultaneously had critical performance issues

• VeloCloud SD-WAN delivers app perf• Dynamically steered VOIP traffic from MPLS to

cable, sub-second without call drops

• On-demand mitigated MPLS and cable issues

How a Manufacturer Got Started

05/01/2023 VeloCloud.com 10

• Critical manufacturing locations in Europe and APAC regions

• MPLS network was not providing enough bandwidth

• Increasing costs as business moved to additional emerging markets (Thailand, Indonesia, etc.)

• Reaching end of 3 year term with MPLS vendor

• Huge SD-WAN interest, but careful steps• Conducted full assessment of internal

environment to determine future state bandwidth and resilience needs

• Lots of sensitivity about a migration due to critical ERP systems at each site

• SD-WAN interest was based on its ability to deliver a high-quality network using Internet – with big bandwidth increases

• Technology POC followed by phased rollout
