With networked applications and security still being the top concerns for most businesses, those that transform their IT and network architectures, and use cloud services, should simultaneously consider transforming their security architectures.
While traditional multi-protocol label switching and wide-access networks have helped in the past, the ever-changing needs of the enterprise will add pressure to the system, and they will struggle to meet these constantly shifting demands. What all of this means for the end-user is that SD-WAN can provide increased control and security, allowing for connectivity bandwidth at a much lower cost than traditional WAN setups. It also provides enterprises with more options for connections, while increasing the number of vendors and services available when building a network.
The intelligent SD-WAN edge devices can then make application-based decisions when the backup link is activated; ie, only allow business-critical applications, and hold back traffic such as large file transfers until the secondary line is restored, while maintain the service levels and security for business-critical applications.
