How SD-WAN Enables Digital IT Transformation

How SD-WAN Enables Digital IT Transformation

Today, most enterprise IT executives are in the process of implementing or developing a digital transformation strategy to support their business objectives. This is often accompanied by an adoption of a cloud-first strategy that supports on-demand access to any business application from anywhere and from any device, wherever the application resides. As we move ahead in this dynamic market, the digital enterprise, IoT, mobility, and machine learning (ML) are the disruptive forces that lead us to reconsider the fundamental architecture of the enterprise wide area network (WAN).

A common question we hear from customers is: “Can an SD-WAN help an enterprise accelerate this transformation?”

Legacy enterprise IT and network infrastructure were designed at a time when most applications were hosted in on-premise datacenters and application traffic from the branch sites was backhauled to the datacenter. This is inefficient for today’s traffic patterns where there are requirements to access a cloud-hosted application from any branch using the internet; backhaul adds latency which impairs cloud application performance.

SD-WAN can enable enterprises to accelerate a migration from a legacy network architecture to a new business-first networking model that optimizes the WAN more effectively and economically while ensuring high throughput, performance, availability, and security for all business applications. Basic SD-WAN optimization solutions can support flexible WAN connectivity and improve performance but fall short of delivering high performance, fully automated, and cloud-optimized solution that a business-first network enables. With a business-first networking model, the network enables the business, rather than the business being forced to conform to the constraints of the network.

In this new multi-cloud era, businesses are faced with an entirely new set of questions and challenges. For example, how do they:

  • Keep up with changes to their WAN without configuring policies device by device?
  • Deliver new applications to thousands of sites, across multiple clouds, in 10 percent of the time?
  • See everything and always know which WAN issues to focus on across thousands of sites?
  • Reduce human error in a complex and ever-changing environment?

HCL partners with Silver Peak and employs the Unity EdgeConnect™ SD-WAN platform as part of a comprehensive managed SD-WAN service that uniquely addresses all of these challenges. This enables enterprises to benefit from the highest quality performance of business-critical applications, including voice and video over broadband.

As a leading Global System Integrator (SI), HCL is considered a trusted advisor to many large enterprises for implementing IT and digital transformation projects because they take an independent/agnostic approach to their customer’s business. HCL’s WAN expertise includes recommendations for implementing SD-WAN solutions and services. Their approach is consultative when it comes to identifying and implementing end-to-end network services and transport network solutions. It incorporates leading SD-WAN vendor solutions that support HCL’s strategy is to provide enterprises with a Transport Independent Site (TIS) framework for WAN solutions that are independent of the service provider and an underlying transport network.

HCL’s approach is consultative when it comes to identifying and implementing end-to-end network services and transport network solutions.

Transport Independent Site  helps transform today’s WAN to a next-generation, intelligent WAN edge which can leverage any service provider’s transport service (MPLS, DIA, broadband, LTE, DSL, or satellite) and integrates application visibility, path conditioning, security, WAN optimization, cloud intelligence, advanced routing, and flexible provisioning in a single flexible software-based platform. The EdgeConnect™ SD-WAN platform complements the TIS framework, and through continuous adaptation and the ability to improve the performance of underlying transport services, EdgeConnect delivers the highest performance and uninterrupted user access to applications and ongoing alignment with business intent.

By leveraging the EdgeConnect SD-WAN platform, HCL offers complete visibility and control of a customer’s WAN infrastructure by providing high network and application availability and resiliency. Real-time monitoring of transport networks is critical to ensure that revenue-driving applications are running at the highest levels of performance and are always available. With HCL managing the WAN, digital enterprise customers benefit from an independent analysis and update on how their transport networks are performing. In addition, HCL can rapidly deploy an SD-WAN service since they are not concerned with installing/replacing a WAN circuit. 

HCL’s managed SD-WAN, powered by Silver Peak, brings immediate value to enterprise clients by enabling them to utilize existing WAN connectivity from any existing service provider. The service also supports HCL’s value-add WAN Optimization-as-a-service, based on Silver Peak Unity Boost TM, which ensures that there are no compromises for performance and latency of the enterprise applications at locations that experience issues with degraded network conditions.

Through this strategic partnership, HCL’s managed SD-WAN service is available to enterprises globally. HCL can address the burgeoning demand from enterprise clients for a comprehensive SD-WAN service which can securely optimize the use of cloud-enabled applications and help accelerate the digital transformation strategy.
