The promise of digital transformation is based on operational simplicity, better application performance, more business agility and increased responsiveness to external variables such as competition and technology innovation. While the virtualization of compute and storage resources coupled with innovations in DevOps, the WAN was largely ignored and has remained stagnant while everything else has evolved. Cloud (public, private and hybrid) is the passing lane in the digital transformation journey. To achieve these transformation benefits, enterprises migrate their workloads and applications to public cloud Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) targets. These migrations have increased demands on the WAN while putting additional stress on the performance and security control points that have traditionally resided in an enterprise data center. Network traffic supporting users wanting access to cloud applications have to “trombone” back to central data centre sites to be validated and authorized and then bounce back out of the data centre to reach the cloud destination. This is very inefficient especially in a global setting. TCP/IP conversation profiles, latency, packet loss and variable network performance means poor and irregular end user experiences, the result of poor overall application performance.

Telco (Carriers) are historically, the main providers of WAN services to enterprises. Historically, they also provided legacy voice services. Voice services over PSTN (Public Switched Telephone Network) could migrate to VoIP (Voice Over Internet Protocol) but sound quality issues were visible in the early adoption. Silos were born as data network operations did not want voice network operations to compromise the integrity and performance of business applications running on the network. Most enterprises had separate voice and data networking teams in their IT organizations to service these requirements. MPLS has been used at high cost and commitment to manage resources serving both data and voice. In a cloud enabled world, SD-WAN is an excellent cloud connectivity solution that addresses these issues and eliminates these silos.

Another SD-WAN decision point is the question of construction (aka DYI, CapEx, asset purchase) or consumption (aka Managed Service, OpEx, subscription). For companies that have contractual commitments to MPLS, utilize Dedicated Internet Access (DIA) in remote locations/branches and maintain the necessary IT Network resources to manage the environment, introducing the DYI SD-WAN model may be adequate to keep the lights on. Troubleshooting poor cloud application performance, security breaches, cloud and SaaS applications integration, the inability to “scale up or down” on demand and last but not least, the “snailnet” responsiveness and speed of legacy telcos that enterprise has been conditioned to expect, can be a showstoppers for successful digital transformation success stories. Precedent has been established with the subscription based cloud consumption model. The same principles can be applied to create a complimentary network consumption model.


SASE (Secure Access Secure Edge), pronounced “sassy”, is this emerging cybersecurity concept coined by Gartner in a report called “The Future of Network Security in the Cloud in August 2019. Digital organizations needed a new approach for network security in a world of cloud services, remote users, SaaS applications and essentially a data centre bypass from users wanting to access non-data centre applications like those provided by Cloud Service Providers (CSPs) such as Google, MS Azure, AWS and Oracle Cloud. It is based on entity identification. These identities can be associated with people, groups (branch offices), devices, applications, services, IOT (Internet Of Things) systems or edge computing locations. In summary, SASE results from the integration of the Security Service Layer and the Network Service Layer. The Security Service Layer includes: FWaaS – Firewall as a Service; CASB-Cloud Access Service Broker; ZTNA-Zero Trust Network Access; Cloud SWG-Secure Web Gateway. The Network Service Layer includes: SD-WAN-Software Defined Wide Area Networks.
