What is Cloud WAN?
Cloud WAN is a software-defined approach to managing wide-area networks (SD-WAN). It provides dynamic connectivity among branch offices, data centers and clouds.
To accelerate innovation and agility, I&O leaders should maximize WAN product investments by migrating to SD-WAN technology as a direct replacement to traditional routing at the WAN edge.

Benefits of Cloud WAN
Private global backbone
Zenlayer Cloud WAN is built on top of our private global backbone to ensure ultra-low latency and reliability.
Simple
Zenlayer Cloud WAN is simple to deploy with our zero-touch configuration customer premise equipment (CPE). For enterprises who prefer instant deployment, we can also provision virtual CPEs remotely.
Users can add, delete or change sites, links, connections, routing configurations and policies across the entire network in our easy-to-use online portal.
Flexible
Zenlayer Cloud WAN supports multiple types of connections (Internet, 4G/LTE, MPLS, leased line, etc.) and sites (branch office, data center, private cloud and public cloud).
Reliable
- Built-in redundancy and automatic failover in Zenlayer's backbone and networking devices.
- Supports multiple PoP connections to a single site for disaster recovery
- Auto network migration when one connection is down (if organization has multiple connection types/providers)
- Hot swapping functionality is built into the CPE
Secure
- Global private backbone is shielded from the public Internet and unauthorized entries.
- Encrypted IPSec tunnel ensures network security if the last-mile traverses over the public Internet.
- Multiple access controls such as 802.1X, CPE network and direct Internet access control combined with unauthorized access alerts.
- Tenant and subnet isolation ensures each customer is isolated from other customers, and groups within an enterprise Intranet can be isolated from each other as well.
Cost-effective
Optimize performance vs. cost
- Specify quality of service (QoS) and connection types based on application importance
- Use high-cost connections (private lines, local loop, etc.) for mission-critical applications only
- Use low-cost public Internet or direct Internet access (DIA) for less critical applications
Pay-as-you-go
- Month-to-month service, cancel any time
- Change bandwidth limit any time based on business needs
