In the world of software-defined wide-area networks (SDWAN), there are two primary deployment options: cloud data center SDWAN deployment and on-premises data center SDWAN deployment. Each option has its own unique set of advantages and disadvantages, as well as different cost implications, security considerations, and best practices for implementation.

Understanding the Basics of SDWAN

Before we dive into the differences between cloud data center SDWAN deployment and on-premises data center SDWAN deployment, it’s important to have a basic understanding of what SDWAN is and how it works. Essentially, SDWAN is a technology that allows businesses to create a virtual network overlay on top of their existing physical network infrastructure. This virtual network overlay is managed through software, rather than hardware, which allows for greater flexibility and scalability.

SDWAN is designed to optimize traffic routing and improve network performance, particularly for applications that are hosted in the cloud or accessed remotely by employees working from different locations. By using SDWAN, businesses can potentially save money by reducing their reliance on costly MPLS (Multiprotocol Label Switching) connections and instead leveraging less expensive broadband links.

One of the key benefits of SDWAN is its ability to provide greater visibility and control over network traffic. With traditional WAN (Wide Area Network) architectures, it can be difficult to monitor and manage traffic flows, particularly when dealing with multiple locations and remote workers. SDWAN, on the other hand, allows businesses to easily monitor and prioritize traffic based on application type, user location, and other factors, ensuring that critical applications receive the necessary bandwidth and resources.

Another advantage of SDWAN is its ability to provide enhanced security features. With the rise of cloud computing and remote work, traditional security measures such as firewalls and VPNs (Virtual Private Networks) may not be sufficient to protect sensitive data and applications. SDWAN can help address these security concerns by providing features such as encryption, segmentation, and threat detection, helping to ensure that data remains secure and protected from cyber threats.

Advantages of Using SDWAN for Your Business

There are numerous benefits to using SDWAN for your business, regardless of which deployment option you choose. Some of the key advantages include:

  • Improved network performance: SDWAN technology is designed to optimize traffic routing and improve network performance, particularly for cloud-hosted applications and remote employees.
