In today’s networking landscape, the cloud computing has evolved into four major paradigms: public cloud, private cloud, hybrid cloud and multi-cloud. However, the rising workloads emerged and generated from mobile devices, including video streaming, security authentication, and A.I. or IoT related applications, have increasingly occupied the traffic from user ends to the central cloud, causing latencies in user experiences. Therefore, the recent concept of “Edge Cloud” has been introduced as the initiative to reduce the latencies for IoT or CDN (content delivery networks) applications.

The market momentum of SD-WAN has dramatically redefined the networking ecosystem in both architectural and management approaches in just few years. Indeed, SD-WAN has brought the benefits of improved real-time application performance and simplifying the WAN management and deployment. Along with the rising phenomenon of edge computing, SD-WAN appears to be on a continuously evolving technology as major industry leaders in this field have continued to expand its functionality and even its boundary, which some refer it as “Network Edge”.

The rapid growth of cloud data centers in recent years has been the driving force for the introduction of single-lane 25 Gigabit Ethernet specification, and this new technology has been the game changer for switch and server designs. The 25G Ethernet, firstly announced by 25G Ethernet Consortium with members of Arista, Broadcom, Google, Mellanox Technologies and Microsoft in 2014, has since revolutionized Ethernet development roadmap.

When 4G/LTE was first introduced, communication service providers (CSPs) were delivering uniform services and relying on proprietary equipments when they expanded their coverage. However, CSPs have been challenged by the widespread of mobile devices and cloud applications, which has led to the era of Big Data. CSPs revenue has shrunk due to a highly competitive market while users demand better quality of service (QoS) and quality of experience. In order to improve competitiveness in the demanding market, CSPs have embraced NFV (network function virtualization) to capture future business opportunities.

There is no doubt that SD-WAN has become one of the most widespread paradigm shift in the technology field over the past few years. Indeed, SD-WAN offers multiple advantages for enterprise WAN management, including the simplicity in traffic routing, lowered dependence on MPLS, and the cost-effectiveness through implementation on existing traditional WAN hardware. However, like all the widespread technological trends, security becomes the primary concern once the market reaches maturity.

The rise of smart mobile devices has changed the ways that network architecture is managed. Since the introduction of smartphones, more and more user contents have been generated from such mobile devices than client-server computers, and that’s why enterprises have been competing in the offering of cloud services and Big Data management. Thus, the dynamically changing traffic pattern has driven the trends to revolutionize network architectures.
