Geo Redundant Design
As a service provider, it’s important to remember the two key factors that contribute to high availability in a network on which communications applications are deployed: peak-load capacity and redundancy. Peak-load capacity refers to the number of simultaneous users and devices a network can handle. Redundancy measures the extra capacity that can be used in the event of an equipment, network, or application failure.
Ensuring that a network can properly handle targeted peak-load capacity while having the redundancy needed to run in case of unexpected issues is critical to ensuring high availability. The best way to achieve this, in short, is through geo-redundancy.
Efficiency
Yonder deploys call processing in an active-active, geo-redundant configuration which ensures that traffic is always actively forwarded to achieve maximum performance gains. In this situation, all nodes are online and pass call information, feature codes, voice mail, and other traffic simultaneously under normal conditions. So if one fails, the system shifts traffic over to the remaining nodes. With no down time or loss of network connections.
Business Continuity
Yonder seamless fail overs have significant benefits for business continuity. After all, the availability of multiple, geographically-dispersed high-capacity nodes means that there is no single point of failure. At least one alternative path for traffic flow is always available. Thus, in case of a natural disaster, human error, or even a DDoS attack, users stay up and running.
Simple Scalability
Yonder geo-redundancy is also a plus when it comes to affordability and scalability. Using an active-active operation enables Yonder to upgrade and patch hardware/software without planning for downtime. As a result, this empowers us to perform system maintenance and add new features without fear of adversely affecting an end-user’s experience.
N-Share
Critical to our geo-redundant design is n-Share. With n-Share, the data and processes from one Point of Presence (PoP) are being actively replicated and shared across all other PoPs in real time. Using an active-active deployment, n-Share nodes run separately from each other. So that an event that impacts a node on one network is unlikely to interrupt the nodes on other networks.
In other words, geo-redundancy through n-Share is the smart way for Yonder to leverage the power of redundancy in ensuring high availability for our end-users.
