Additionally, if one of the dedicated connections fails, it can cause significant disruptions to the network, leading to downtime and lost productivity. Therefore, it is essential to have a robust network management system in place to monitor and manage the dedicated connections effectively.

Cost Comparison between Aggregated and Dedicated Internet Access SDWAN Deployment

The cost of SDWAN deployment will depend on the approach chosen, and the total cost can differ significantly based on the number of remote sites, the number of links required, and the level of service required by each. In general, aggregated internet access SDWAN deployment can be more cost-effective than dedicated internet access SDWAN deployment. Still, costs also depend on the specific service providers and the level of services required by each remote site.

It is important to note that while aggregated internet access SDWAN deployment may be more cost-effective, it may not always be the best option for every organization. Dedicated internet access SDWAN deployment can provide higher levels of security and reliability, which may be necessary for businesses that handle sensitive data or require uninterrupted connectivity.
