Hybrid WAN

Hybrid WAN definition

Hybrid WAN refers to a networking architecture model that creates a unified network infrastructure by combining multiple connection types and technologies. It typically includes a mix of private and public connections, such as MPLS, broadband internet, and cellular networks. Hybrid WAN is designed to use multiple connection types to provide increased bandwidth, reliability, and flexibility.

Hybrid WAN use cases

  • Branch connectivity. Hybrid WANs are commonly used to connect branch offices to a central corporate network, providing reliable connectivity regardless of location.
  • Cloud connectivity. They enable organizations to connect to cloud services and different applications. Also, because they use a combination of private and public connections, connection is optimized for performance.
  • Backup. Using multiple connection types ensures data can be recovered in cases of network failures.
  • Optimized traffic routing. Hybrid WAN can route traffic based on application requirements, performance metrics, and cost considerations.

Hybrid WAN drawbacks:

  1. 1.Security concerns. Integrating public internet connections into the WAN introduces potential security risks. The company must take appropriate measures to address those risks.
  2. 2.Lack of consistency. Hybrid WAN is a complex network that needs careful configuration to prevent performance inconsistencies.
  3. 3.Dependency on service providers. Organizations rely on multiple service providers for different connection types, and they can face difficult issues if any of those services are discontinued.
