SD-WAN uses software to make intelligent network data decisions and allows for greater flexibility and control.
While MPLS gives a dependable service over a private fixed network, it has many drawbacks for modern businesses. With increasing cloud adoption and users working from varying locations accessing multiple applications, SD-WAN gives enterprises enhanced security and improved visibility over their network.
Enterprise A use case
Enterprise A has a HQ in Dubai with three branch offices across MENA connected via a private MPLS connection. Their network team currently spends more than half of their time maintaining, upgrading and reporting on the network.
Enterprise A is expanding and wants to add another 3 branches in different countries, whilst migrating most of their applications to Azure and AWS. Continuing to use MPLS will take months of work and entail involving third party access for the fixed circuits. The MPLS costs and delivery time frames will negatively impact their launch budget and delay the opening of the new branches.
By implementing an SD-WAN over broadband internet-based solution, Enterprise A is able to open their new branches on time and within budget. The flexibility of SD-WAN means that their new branches will be up and running in days rather than months, including ExpressRoute and AWS Direct Connect allowing connectivity to all cloud-based applications. The network team as well as the business stakeholders will have real-time visibility of the network and application performance. Day-to-day managements and infrastructure upgrades are automated allowing the network team to focus on core business projects. rather than just maintaining a legacy MPLS network.
