Understanding Managed SD-WAN

Defining Managed SD-WAN

Managed SD-WAN, as the name suggests, is a networking service provided by a managed service provider. It involves the deployment, management, and support of SD-WAN technology by a third-party service provider. When a business decides to opt for managed SD-WAN, they rely on a service provider to handle the intricacies of SD-WAN implementation, configuration, and ongoing management. The service provider takes care of network infrastructure, connectivity, security, and application performance, allowing businesses to focus on their core operations without worrying about network complexities.

 

How Managed SD-WAN Functions

Managed SD-WAN optimizes network performance and user experience by leveraging management techniques. It offers visibility, control over network traffic, application prioritization, and bandwidth allocation. Advanced routing algorithms minimize latency for efficient application delivery. Intelligent routing mechanisms select the best path based on real-time conditions, ensuring optimal performance and user experience. By outsourcing network management, businesses can enhance productivity with improved performance and reduced downtime.

SD-WAN as a service vs Managed SD-WAN

Key differences and similarities

SD-WAN as a service primarily focuses on network management, providing businesses with a cloud-based platform to centrally configure and control their SD-WAN deployment. On the other hand, managed SD-WAN goes beyond network management, offering a broader range of services including deployment, configuration, network performance optimization, and security management. Both solutions share a common goal of optimizing network connectivity, improving user experience, and reducing costs. However, managed SD-WAN provides a more comprehensive network management approach, leveraging automation, analytics, and secure access service edge (SASE) capabilities to deliver a holistic networking solution.

Choosing the right solution for your business

Choosing between SD-WAN as a service and managed SD-WAN depends on various factors, such as the size of your organization, network requirements, and available IT resources. To make an informed decision, consider the following points: 

  • Evaluate the scalability of the solution, ensuring it can handle the growing demands of your entire network infrastructure, including data centers and remote locations. 
  • Assess the level of network management expertise within your IT team. If you have limited resources, managed SD-WAN may be a better choice as it offloads network management responsibilities to a service provider. 
  • Consider the deployment model that aligns with your business needs. While SD-WAN as a service offers agility and quick deployment, managed SD-WAN provides end-to-end support and ongoing management. 
  • Evaluate the cost implications of both solutions, factoring in the initial setup costs, ongoing management fees, and potential savings on network bandwidth utilization.
