How to know when to switch from MPLS to SD-WAN

Quick Read

Multiprotocol Label Switching (MPLS) has been the traditional wide area network (WAN) solution for businesses for many years, but Software-Defined WAN (SD-WAN) technology is becoming increasingly popular as an alternative. Here are some key factors to consider when deciding whether to switch from MPLS to SD-WAN: 

1. Network performance: If your business is experiencing issues with network performance, such as high latency or limited bandwidth, it may be time to consider switching to SD-WAN. SD-WAN uses advanced routing algorithms to dynamically route network traffic over the most efficient path, which can significantly improve network performance. 
2. Cloud adoption: As more and more businesses are adopting cloud-based services, the use of MPLS may not be the best fit. SD-WAN solutions are better suited for cloud-based environments, as they can provide better performance and security when connecting to cloud-based services. 
3. Security concerns: MPLS networks can be vulnerable to security threats, SD-WAN solutions can provide enhanced security by encrypting network traffic and using advanced security features such as firewall and VPN capabilities. 
4. Cost-effective: MPLS networks can be expensive to maintain and upgrade. SD-WAN solutions often use less expensive internet connections rather than expensive MPLS circuits, which can be more cost-effective for businesses. 
5. Flexibility: SD-WAN solutions provide more flexibility than MPLS, by allowing businesses to easily add new sites, branches, and remote users to the network. 
6. Scalability: As your business grows, the ability to easily scale your network can become increasingly important. SD-WAN solutions are designed to easily scale up or down as needed, which is not always possible with MPLS. 
7. Remote workforce: If your business has a growing remote workforce, a SD-WAN solution can provide a better connection for remote employees as it uses multiple internet connections to ensure reliability and availability. 

In conclusion, switching from MPLS to SD-WAN may be the best decision for your business if you are experiencing issues with network performance, adopting cloud-based services, facing security concerns, looking for cost-effective solutions, needing more flexibility and scalability or a growing remote workforce. It is important to evaluate your current network and understand your business's needs before making a decision. It is also recommended to consult with industry experts and vendors to understand the costs and benefits of both options before making a final decision.
