Hybrid Wan Design

5 keys to get full value from a hybrid WAN design.

What's digital all about? Better user experiences and a faster path to revenue. 

According to IDG’s 2018 Digital Business research, 89% of organizations have adopted digital-first strategies. Almost 32% of IT decision makers have testified that digital strategies have already helped them meet their revenue growth goals.

But can your current network keep up with your new digital launches?

Research from Forrester shows that 55% of enterprises don’t believe their current WAN can handle their new digital use cases.

In this article, we’ll explain the 5 points you need to consider to make sure your network can deliver digital ROI, and show you how you can run an application assessment to check.

Digital-first strategies are pushing enterprise WAN to hybrid WAN designs

Cloud and mobility are critical components of the enterprise digital-first strategy. CIOs are rapidly migrating existing and new enterprise applications from data centers to the cloud to meet their digital goals across local and global branches. An average enterprise is using a staggering number of 1,427 distinct cloud services, with an average employee using more than 36 cloud services daily at work. On the other hand, nearly 42.5% of the global workforce is forecasted to be mobile by 2020. Access to cloud applications from mobile devices has become a pivotal point from both customer experience and business productivity perspective.

However, networks and their quality have become a determining factor for successful cloud and mobile transformation. These transformations are adding new complexities on enterprise Wide Area Network (WAN) and pushing the traditional WAN edge from centralized datacenters to the cloud, branch offices and ultimately closer to the applications and users of those applications.

In the process, enterprises are moving to hybrid WAN designs to get the value of Application-Aware SD-WAN today without putting the business through the pain of rearchitecting their entire network today.

Give your WAN edge a 5-point application performance assessment

Wide Area Networks must rise to the demand for dynamic performance requirements for both mission-critical and bandwidth-heavy application deployed in hybrid cloud and datacenters environments.
Enterprise IT teams and Managed Service Providers need a solution to intelligently manage application performance and give their WAN Edge a 5-point performance assessment regularly, based on their business goals and objectives. Critical elements of such a performance management system can be launched with a Hybrid WAN design and include:

Application visibility

Guarantee SLA-based application performance. The solution should provide granular and aggregate deep application packet data views and must report a full understanding of application usage and performance over the global network.

Application control

Ensure application quality of experience (QoE). The solution should provide business-intent oriented traffic prioritization and dynamic bandwidth management, per application session, to maximize the quality and bandwidth utilization of all available links.

Dynamic WAN selection (DWS)

Dynamically selecting underlying links based on traffic quality and performance. The solution should provide real-time end-to-end performance analysis of all available links and automatically chose the best WAN connection for each application flow.

Application Performance Troubleshooting

Simplify management of digital customer experience by streamlining trends analysis of various application performance metrics. The solution should identify the source of issues for network and application teams to accelerate troubleshooting and expedite incident resolution.

Application Quality Score (AQS)

Create a common KPI relevant to all applications. The solution should enable IT managers to see how the end users experience application performance and ensure that it is aligned with business objectives.

Modern enterprise networks must ensure that they provide the agility and support required by cloud services, such as unified communications, to deliver traffic that is constantly changing in type and has varied performance requirements. They should be capable of assuring low latency, dynamically allocating the required bandwidth, optimizing network resources and prioritizing application performance based on business intent and objectives.
