SD-WAN growth in 2020 is being fueled by the relationships established between vendors and services providers.
Fremont, CA: The rise in cloud adoption and improved network security, visibility, and manageability are driving the enterprise software-defined WAN deployments at a breakneck pace. Referring to research done by IDC states that software-and infrastructure-as-a-service (SaaS and IaaS) offerings in particular in the reason behind driving SD-WAN implementations in the past year. It further adds that the SD-WAN infrastructure market will hit $4.5 billion by the year 2022, increasing at more than 40 percent yearly clip between now and then. The growth of multi-cloud networking has instigated numerous businesses to re-tool their networks favoring SD-WAN technology.
According 
to a survey conducted the customers on an average have 30 paid SaaS applications individually and have been using over 100 in dome cases. A small slice of this cake called trend is driven by the relationships that networking vendors like Cisco, Juniper, VMware, Arista and many more have been building with the likes of Amazon Web Services, Google Anthos, Microsoft Azure, and IBM RedHat.
An indicator of the rising importance of the SD-WAN and the multi-cloud relationship was the AWS announcement of key services for cloud offerings which included new integration technologies like AWS Transit Gateway which enables the customers to connect their Amazon Virtual Private Clouds and their on-premises networks into a single gateway. Moving on additional features like cloud-based application insights and performance monitoring will be a critical part of SD-WAN rollouts.
The enterprises are now increasingly favoring platforms that solve a broader range of network management and security needs instead of looking at SD-WAN solutions. They will search for SD-WAN platforms which will integrate with other aspects of their IT infrastructure inclusive of the corporate data-center networks, public-cloud resources, or enterprise campus LANs. They generally look for security services to be baked in and also support a range of additional functions like visibility, unified communication, and analytics.
The customers continue to integrate the infrastructure components with software, and that enables them to do some things like implementing consistent management and security policies based on user, the device or application needs throughout their LANs and WANs, while ultimately achieving a better overall application experience.
