What advantage does deploying the SD-WAN controller on-premises provide?

Deploying the SD-WAN controller on-premises provides full control over both the data plane and the control plane. This allows organizations to manage all aspects of their network infrastructure, including security policies, routing, and traffic engineering, within their own data centers. This level of control is crucial for organizations with strict compliance requirements, specific security policies, or complex network architectures that necessitate granular management. Automatic geographical redundancy and security are typically features of cloud-hosted solutions, not inherent to on-premises deployments, which require manual configuration for these aspects. Scalability and cost savings are often benefits of cloud-based solutions due to their elastic nature and pay-as-you-go models, whereas on-premises deployments involve upfront hardware costs and require manual scaling. Ease of deployment and management is generally higher with cloud-based services, which abstract away infrastructure complexities, compared to on-premises solutions that demand internal IT resources for setup and maintenance.
