SD-WAN be the solution?
In order to solve the above problems and challenges, people have focused on SDN. It is hoped that software configuration and management will be more flexible and adaptable through software. With SDN, all network configurations are centralized on storage and management, and devices can be programmed on demand, simplifying hardware and reducing management overhead. Originating from the data center, SDN successfully demonstrated the benefits of developing automated management network software.
But in complex environments, such as load balancing, firewalls, intrusion detection, and wan acceleration, the IT team found that reproducibility in the data center was difficult to manage, not to mention adding a layer of wan connectivity. The Wan connection service is usually purchased from a service provider. The service provider has its own management structure and may have corresponding countermeasures for different capacity, bandwidth and location. Many customers have begun deploying Internet-based VPN solutions to replace the MPLS lines that are needed by extremely sensitive business customers.
Then, if you use SD-WAN, combined with the service provider’s technology, architecture and service products to build a transparent enterprise IP network, you can also add some advanced network features such as application-based routing or custom security requirements, while maintaining Optimizing network functions based on SLA is an ideal way.
