Understanding the Basics of SDWAN Deployment

Before diving into the differences between virtual appliance and physical appliance SDWAN deployment, it’s important to understand the basics of SDWAN deployment. SDWAN deploys a combination of hardware and software to manage a network. Using this technology, network traffic can be optimized, managed and made more secure. This is achieved by the use of a centralized management system that allows for the deployment of policies and configurations to each device on the network. SDWAN has become increasingly popular among businesses due to its ability to enable secure and fast connections across multiple locations.

One of the key benefits of SDWAN deployment is its ability to reduce costs associated with traditional WAN networks. By using SDWAN, businesses can reduce the need for expensive MPLS connections and instead use more cost-effective broadband connections. This can result in significant cost savings for businesses, particularly those with multiple locations.

Another advantage of SDWAN deployment is its ability to provide greater visibility and control over network traffic. With SDWAN, businesses can monitor network traffic in real-time and make adjustments as needed to ensure optimal performance. This can help to prevent network downtime and ensure that critical applications are always running smoothly.

Advantages of Virtual Appliance SDWAN Deployment

Virtual appliance SDWAN deployment is a software-based solution that offers a number of advantages over hardware-based solutions.
