Cloud adoption is becoming an increasingly large part of CIO budgets, to the point where some enterprise organizations are using many different cloud environments to build their IT infrastructure. A multi-cloud model involves the custom selection of multiple cloud services to serve specific functions. Enterprises today have almost entirely embraced multi-cloud for its flexibility by 93% currently have a multi-cloud strategy in place. However, connecting workloads on multiple clouds at the data center WAN edge creates several challenges, including deployment complexity, inconsistent network performance, and expensive connectivity.
Software-defined wide-area networking (SD-WAN) can help facilitate adoption of multi-cloud deployments while simplifying WAN infrastructure and reducing connectivity costs. But in order to be successful, SD-WAN needs to be kept secure.
