I have been asked many times lately by customers why they need to implement SD-WAN when they already have ISP redundancy.
The answer is simple: while ISP redundancy provides a certain level of connectivity, it falls short in comparison to the benefits of SD-WAN.
With ISP redundancy, a network is designed with multiple ISPs to provide redundancy in the event of an outage. However, this redundancy only provides basic failover capabilities and does not offer the advanced features and benefits of SD-WAN.
SD-WAN, on the other hand, offers a wide range of benefits that go beyond basic redundancy. One of the most significant benefits is the ability to intelligently route traffic across multiple links based on network conditions, which allows for optimal network performance and improved application experience. SD-WAN also offers the ability to prioritize certain types of traffic over others, which can help ensure critical applications receive the necessary service they require.
In summary, while ISP redundancy provides basic failover capabilities, it falls short in comparison to the benefits of SD-WAN. SD-WAN offers improved network performance, advanced security, and cost savings compared to traditional MPLS networks. Therefore, customers looking to improve their network performance, security, and cost savings should consider implementing SD-WAN.
