The availability, speed and performance that companies want don't come from cloud computing services alone. Many of the same benefits and attributes are principle to network-as-a-service offerings that are deployed as part of a more holistic IT strategy.
NaaS does not treat all traffic the same, much as cloud elasticity adjusts resources based on how they're consumed. Companies that use NaaS can customize and even prioritize traffic depending on what's best for the business. This could include the bandwidth available for specific applications, users or both.
Though some network components have a fixed cost regardless of the vendor involved, NaaS bandwidth on demand capabilities allows organizations to scale up and down with the same speed and agility that's associated with the "elastic" powers of the cloud.
Becoming a more adaptive enterprise makes it possible to set more ambitious growth targets and achieve them, even if it means grappling with unforeseen events. Talk to a managed service provider to better understand how NaaS can build upon the elasticity cloud computing provides.
