How to Get Started with SD-WAN

05/01/2023 VeloCloud.com 6

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

Asia Pacific focus: How can SD-WAN help here?

05/01/2023 VeloCloud.com 9

1. The cost of private bandwidth in many markets makes Internet-based WANs essential

• Outside of major business centers it is often prohibitively expensive to use MPLS connectivity

• Enterprises operating across the region have frequently leveraged Internet-based connectivity to connect locations to the WAN

• SD-WAN can potentially allow for increased use of Internet connectivity

2. Vast differences in quality and availability of Internet services

• Quality issues with traditional Internet VPNs are a frequent problem for enterprises

• Poor internet connectivity quality often occurs in markets where MPLS bandwidth is the most expensive (e.g., Papua New Guinea, Philippines, Indonesia)

• In some mature markets (e.g., Singapore, Hong Kong), Internet quality is extremely high

3. SD-WAN can turn a fragmented, poorly-performing VPN into an enterprise-grade, cloud-ready WAN

• Combine multiple providers in markets where connectivity quality is poor, without any technical complexity

• Take advantage of huge investment in next-generation mobile data networks to augment terrestrial connectivity

• Seamlessly address variable connectivity quality using per-packet link selection

4. Establish a platform to better support cloud-based infrastructure and applications

• Multinational enterprises operating in APAC are frequently leveraging cloud services hosted outside of the region

• This places an additional focus on extracting the maximum level of quality from Internet-based infrastructure at the branch office level

• Cloud-delivered SD-WAN can seamlessly extend performance mitigation and optimization benefits to cloud-based applications

How a Retailer Got Started

05/01/2023 VeloCloud.com Company confidential. 11

• Move to more cloud apps• Low bandwidth ADSL insufficient to deliver performance

and traffic to the cloud

• MPLS too expensive for cost conscious hundreds of Retail stores across different geographies

• VeloCloud SD-WAN delivers throughput & performance

• Bonds multiple ADSL/4G links to deliver throughput and performance required

• Enable more digital services to be delivered without building parallel networks

How an APAC-based Manufacturer Got Started

05/01/2023 VeloCloud.com 12

• Critical manufacturing locations in APAC and Europe 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
