Cloud computing is no longer a new buzzword, and in fact, cloud computing is approaching to its next evolution: cloud-first strategy. By definition, it specifies all the business networking activities are conducted in the cloud first. Cloud-first strategy makes practical senses for global enterprises with branches worldwide so that employees can synchronize from mobile devices and remote locations. In fact, organizations with initiatives for cloud-first strategy are requiring a virtualized, automated, and agile network orchestration to easily manage their IT infrastructure, in order to manage the increasing traffics on the cloud and their applications. Thus, SD-WAN has become the optimal choice as it also comes with the capability in securing business applications.

More and more Cloud-centric enterprises are realizing that SD-WAN and DPI together prove to be a powerful combination for not only delivering application-based network performance and for improving efficiency, but also for cutting costs and for increasing business sustainability.

SD-WAN has been one of the hottest and fastest-growing technologies in the networking industry for the past years, and the main reasons include ease of deployments, simplified maintenance and management, and the cost reduction. For communication service providers (CSPs), SD-WAN presents a revenue opportunity as they have been encountered with increasing demands for SaaS (software as a service) applications and cloud-based services, which have become a burden for their bandwidth and traffic routing. SD-WAN provides the agility and flexibility to enable CSP with the enhanced bandwidth to meet the pace of today’s networking demands.

As the business world has moved towards further digitalization, the competitiveness of enterprises heavily relies on application serviceability and network performance. In fact, it is the application awareness or even intelligence that drives SD-WAN to be more flexible than conventional WAN architecture in terms of visibility and control to set priority over the network. With application awareness, SD-WAN effectively reduces bandwidth burden and OPEX/CAPEX for IT management.

Medical applications are particularly time-critical since every minute matters. Therefore, healthcare institutes around the world have proposed and deployed the operating model of “connected ambulance”. The concept behind “connected ambulance” indicates an integration of networking, compute and graphical technologies to be installed in ambulance. These technologies will enable the ambulance with real time connectivity, data processing and video communications. In other words, the “connected ambulance” will function as a hub between patients and hospital, and preliminary diagnose can be performed to shorten the treatment procedure once the patient arrives the destination hospital. In fact, it is predicted that streaming of data and video will be one of the primary purposes of a connected ambulance.

The growth of OTT (Over-the-Top) has greatly impacted the ecosystem of TV broadcasting ecosystem, due to the diversified demands of multi-screen video content consumption, wide use of mobile viewing gadgets and changes in CDN (content delivery network). Since the beginning of the digitalization era, OTT has become the mainstream service that broadcasting operators all over the world are striving to provide to their subscribers. Therefore, they realize that the success of OTT lies in the encoding, decoding and transcoding capability in order to support multi-format viewing on various devices.

There is no doubt that SD-WAN has been one of the most preferred networking technology for enterprises and service providers, and in fact, the growth has expanded not only for office settings, but also in outdoor environments. In recent years, various sectors including entertainment, public events, medical and logistics, have installed A.I. (Artificial Intelligence) and IoT (Internet of Things) hardware and software to enhance user experience, and these require better outdoor connectivity.
