Types of SD-WAN A Simple Guide to Understanding Your Network Options

Published: 24 Jan 2025

Types of SD WAN

With its flexibility and affordability, SD-WAN (Software-Defined Wide Area Network) has completely changed how companies manage their network connectivity. But with multiple types of SD-WAN available—on-premises, cloud-delivered, hybrid, and managed—how do you know which one suits your needs best? Many businesses struggle with slow networks, high costs, and limited scalability, making it crucial to choose the right SD-WAN type. Whether you’re managing local operations or connecting remote teams, understanding these options can save time, money, and frustration.

SD WAN Types

There are several varieties of SD-WAN (Software-Defined Wide Area Network), each designed to satisfy particular business requirements. Here’s a quick overview of the main types:

  1. On-Premises SD-WAN
  2. Cloud-Delivered SD-WAN
  3. Hybrid SD-WAN
  4. Managed SD-WAN

On-Premises SD-WAN

On-Site One kind of SD-WAN is one in which the infrastructure of an organization houses the hardware and software locally deployed and maintained. It provides more control and security since everything is kept on-site. However, it requires dedicated IT staff for management and can have higher initial setup costs.  

Example: A financial institution with sensitive customer data may prefer On-Premises SD-WAN to ensure tighter security and compliance with industry regulations.

Advantages of On-Premises SD-WAN

  • Greater Control: Complete control over the network and security settings.  
  • Enhanced Security: Local management reduces exposure to external threats.  
  • Customizability: Tailored to meet specific business and network requirements.

Disadvantages of On-Premises SD-WAN

  • High Initial Cost: Requires significant upfront investment in hardware and setup.  
  • Resource Intensive: Needs dedicated IT staff for maintenance and management.  
  • Limited Scalability: Expanding the network can be more complex and costly.

Cloud-Delivered SD-WAN

A completely cloud-based solution, cloud-delivered SD-WAN offers network optimisation and centralised management across several sites. It offers greater flexibility and faster deployment compared to On-Premises SD-WAN, as there’s no need for on-site hardware. However, it relies on a stable internet connection for performance.  

Example: A global company with remote offices in different regions might choose Cloud-Delivered SD-WAN to streamline operations and improve connectivity without the need for extensive on-site infrastructure.

Advantages of Cloud-Delivered SD-WAN

  • Quick Deployment: Faster setup with no need for on-site hardware.  
  • Scalability: Easily scalable to accommodate growing network needs.  
  • Centralized Management: Simplifies network monitoring and troubleshooting from a single cloud-based interface.

Disadvantages of Cloud-Delivered SD-WAN

  • Relies on Internet Stability: Performance depends on a strong, consistent internet connection.  
  • Less Control: Limited control over hardware and infrastructure management.  
  • Security Risks: Data is transmitted over the internet, potentially increasing exposure to cyber threats.

Hybrid SD-WAN

The adaptability of SD-WAN and the dependability of conventional WAN are combined in hybrid SD-WAN. It allows businesses to use both on-premises and cloud-based solutions, optimizing network traffic for both security and performance. This setup is ideal for businesses transitioning to full SD-WAN or those needing a mix of both technologies.  

Example: A large retail chain may use Hybrid SD-WAN to keep critical in-store applications on a traditional WAN while utilizing cloud services for other parts of the business.

Advantages of Hybrid SD-WAN

  • Flexibility: Combines traditional and SD-WAN for a versatile network solution.  
  • Optimized Performance: Prioritizes traffic for improved efficiency and reliability.  
  • Smooth Transition: Eases the shift from traditional WAN to SD-WAN without disruption.

Disadvantages of Hybrid SD-WAN

  • Complex Management: Requires expertise to manage both traditional WAN and SD-WAN.  
  • Higher Costs: Can be more expensive due to the need for both technologies.  
  • Integration Challenges: Difficulty in seamlessly integrating legacy systems with SD-WAN.

Managed SD-WAN

Managed SD-WAN is a fully outsourced SD-WAN solution where a third-party provider handles all aspects of the network, from setup to ongoing management. It simplifies operations for businesses that lack in-house IT resources while ensuring optimal performance and security.  

Example: A small business without an IT team may opt for Managed SD-WAN to ensure efficient network performance without needing to hire or train staff.

Advantages of Managed SD-WAN

  • No IT Expertise Needed: Managed by a third-party provider, reducing the need for in-house IT staff.  
  • Simplified Management: The provider handles setup, monitoring, and maintenance.  
  • Cost-Effective: Avoids the costs of hiring dedicated IT professionals and managing infrastructure.

Disadvantages of Managed SD-WAN

  • Less Customization: Limited ability to tailor the network to specific business needs.  
  • Ongoing Costs: Monthly fees for management can add up over time.  
  • Dependence on Provider: Relies on the third-party provider for performance and issue resolution.
