SD-WAN

 


SD-WAN offers enterprises high degree of flexibility for WAN load balancing, optimization and visibility. SD-WAN consolidates multiple networking functions into a single software-defined vCPE platform which virtualizes all the network functions with enhanced service agility, security and QoS (Quality of Service).

 

 

Enterprises nowadays are migrating to the Cloud in droves and more and more software are being licensed, delivered and deployed using SaaS; such migration and deployment have become the norm for the so-called hybrid workplace model that mixes in-office and remote work, especially during the pandemic.  

The finance industry has always had a fairly tech-forward mindset, and financial institutions have become more aware of the need to adapt to digital transformation. A growing number of retail banks and other financial organizations have begun using the technology to hedge the move to cloud solutions to implement new digital services and develop more customer-centric services.

In today’s digital world, designing and implementing a public safety system requires considering an entire ecosystem, from applications, services, and property and network infrastructure. Deploying a high-quality software-defined wide area network (SD-WAN) is essential to operate a public safety ecosystem, which can enhance the speed, efficacy, coverage, and reliability of first responders by enabling citizens and public safety answering points to send and receive voice, text, photos and video communications over a wireless network.

Software-defined WAN solutions can bring unparalleled agility and cost savings to networking, which has been the primary fuel for the rapid growth of SD-WAN in recent years.  Organizations, from enterprises, small-medium businesses to cloud and managed services providers, can deliver more responsive, more predictable applications at lower costs in less time than the traditionally used legacy equipment.

Organizations are increasingly embracing cloud computing to support new applications, keeping pace with ever-increasing quantities of data, and fluctuating customer demands.  Software Defined Wide Area Networks (SD-WANs), as a hardware appliance, was a necessary first step as it supported the transition from legacy systems, and could handle the workloads and complexities of multi-cloud distribution.

The Covid-19 pandemic has created a ‘new normal’ of work-from-anywhere, making the transformation of both WAN and security architectures a top priority for the enterprise.

The disparity between workplace and in-home security is also brought to the fore, highlighting the inadequacy of any one-size-fits-all approach to security. With differing roles, devices and security policies in homes and businesses, an Edge Appliance must be able to automatically detect individual users and devices on the network and apply an appropriate security policy for each.

Organizations with distributed branch offices are having difficulty installing and maintaining WAN implementations. Current WAN technologies are complicated, expensive, and rigid. For example, when provisioning a network service to a branch office, organizations require a new CE (Customer Edge) to be sent to the branch office, plus new lines, configuration, and synchronization with PEs (Provider Edge), and of course, the presence of a technician. The expenses end up being relatively high.
