With the rise of the cloud affecting how infrastructure is set up and networks are run, IT managers should consider whether they should move their wide area network (WAN) to the cloud. Managers have the option to virtualize WAN technology like branch office routers, virtual private networks (VPNs), and more so that these features work in the cloud instead. This puts less strain on hardware and reduces the need to manage physical systems and devices.
IT managers should understand the following steps, which are necessary to plan their cloud WAN correctly.
1. Consider Traffic and Adjust Specifications
With switching their WAN to the cloud, managers should take into consideration how they will integrate their systems with the cloud and virtualization of their WAN technology. This includes branch office routers and other hardware that are crucial for enterprise telecommunications. Make sure to optimize traffic when moving WAN technology to the cloud.
2. Choose the Type of Data Center
IT managers can choose a data center built for multiprotocol label switching (MPLS) or another option like a carrier Ethernet service. Consider the amount of users throughout the system as well as the amount of bandwidth necessary to support them.
For example, IT managers may need a major cloud data center if their bandwidth requirements are high and the cloud WAN must support a large amount of workers spread throughout, while fewer employees and lower bandwidth requirements could call for a branch cloud data center.
3. Upgrade Network Security
While virtualization of WAN technology has plenty of benefits, including the potential to save companies money, there are risks IT managers need to be aware of before switching over to these systems. When moving systems and data into the cloud, there may be a higher chance of a data breach without the right procedures in place.
Ensure information that is part of cloud WAN is encrypted, such as through 256 bit AES encryption for WAN traffic. Data encryption is just one layer of protection a business should have to protect against data breaches.
When set up effectively, cloud WAN services can reduce hardware costs and maintenance. Companies can save money by virtualizing current WAN technology, and cut energy bills due to cloud WAN’s greater efficiency and lower overhead costs.
