NaaS: Is it right for you, and how do you pick a vendor?

Enterprises have become comfortable switching from the purchase-and-refresh cycle for servers, storage and applications to a cloud-based as-a-service approach. So, why not take the same tack when it comes to the network?

That’s the concept behind Network-as-a-Service (NaaS), which promises predictable costs, increased agility, better performance, cloud-style scalability, timely integration of new technologies, service-provider-level security, and a high degree of automation.
