Today's networks support a very different IT environment compared to just a few years ago. There has been a significant rise in the use of mobile clients, increased adoption of cloud-based applications, and the introduction of the Internet of Things (IoT).
As businesses have digitised, the scale of networks and networking needs have grown over the years, without a proportionate increase in IT resources. The end-user's expectations have also been rising, with businesses continually expecting IT to keep up with their evolving technology and growth needs. The networking technologies that have been the foundation of providing interconnectivity between clients, devices and applications have remained static.
While today's IT teams have a number of technology choices to design and operate their networks, there hasn't been a comprehensive, turnkey solution to address their evolving enterprise needs around mobility, IoT, cloud and security, until now…
By adopting an intent-based approach, networks will meet these challenges. They can understand the business intent and continuously align to it. They will use context and analytics to constantly learn and adapt to changing needs and conditions. And, fully integrated security capabilities will constantly protect organisations.
Software Defined Wide Area Networking (SD-WAN) allows you to manage your entire WAN from a single management platform, this is radically different to a traditional WAN where each device is configured and managed individually. The controller for SD-WAN can be hosted in the cloud (AWS) or on-site or a combination of both.
SD WAN can utilise any connectivity method and turn it into a WAN, typically links can be 3G/4G, LTE, MPLS, DSL, etc.. SD WAN will evaluate which link will service different types of traffic most efficiently. e.g. voice or video can be sent over quicker higher quality links, whilst more affordable links can be used for messaging and email, where superfast down load of large data files is not as essential. Its all about utilising the best tool for the job.
