Enterprises preparing to adopt Secure Access Service Edge should understand how the architecture presents organizational and architectural challenges for network and security teams.
Following the on-demand trend, network on-demand options provide enterprises with more flexible consumption models, such as managed network services and cloud-based networking.
As networking pros evaluate SD-branch vs. SD-WAN, they’ll notice a key distinction between the two technologies, namely how network functions are managed and orchestrated.
SD-WAN can improve WAN performance in three ways: It adds a secondary transport for network traffic, while also taking advantage of broadband Ethernet and application acceleration.
When rolling out software-defined WAN, you’ll need to consider the current makeup of your branch offices. For instance, are applications on-site or in the cloud?
Software-defined WAN architecture has adapted with the growth of cloud services, resulting in a cloud-based model that uses SD-WAN gateways to handle traffic and control.
When deciding which applications to move to a cloud data center, enterprises should consider network bandwidth requirements and latency, among other factors.
Cloud computing pools resources that are provisioned and orchestrated on the fly, enabling IT to respond quickly to changing business needs. This kind of flexibility means a clearly defined cloud strategy is now an essential element for every successful IT department. The question is no longer if IT will use the cloud, but instead how it will use it.
In the new year, expect SDN and SD-WAN to come back down to earth. Meanwhile, multi-cloud, edge computing and intent-based networking will ramp up. Plus, data centers are not dead.
Enterprises want their applications to be portable and able to shift easily among multiple cloud providers. To do that, putting together a good cloud migration plan is a must.
