Why Visibility, Robust Reporting And Granular Analytics Are Critical To Your SD-WAN Deployment
SD-WANs are here and becoming a hot topic for most IT organizations. The benefits of having an agile WAN that leverages the capacity and economics of broadband connectivity while delivering improved application SLAs is a strong SD-WAN driver. While the benefits are enticing, many organizations are wrestling with how to manage and troubleshoot a modern SD-WAN since it changes how the WAN is architected and introduces multiple new technologies. Some of the key SD-WAN changes and corresponding challenges include:
- The deployment of multiple WAN links that can include MPLS, Internet, cellular and satellite infrastructures as a part of Hybrid WAN. This approach introduces multiple paths and multiple providers for application traffic to traverse. While this can help with resiliency and performance, it can also make it more difficult to monitor and control the WAN.
- The use of virtualization (e.g. overlays) to abstract the underlying multi-link physical infrastructure can increase reporting and troubleshooting complexity since administrators will now need to correlate issues between the physical and virtual layers.
- The implementation of dynamic infrastructures where the best path for application traffic can change in an instant based on business and application policy. This dynamic nature can make it difficult to establish baseline data and troubleshoot problems due to multiple, changing variables.
With these challenges identified, the SD-WAN capabilities that will greatly help address these issues include automated provisioning, sophisticated reporting and the availability of granular analytics that are correlated across the WAN. For those of you that use or are considering Talari for your SD-WAN, we have some good news. Talari’s Software Defined Thinking WAN delivers this type of a robust SD-WAN solution today through the use of the following:
- A controller that acts as the logical center of the network and coordinates and synchronizes between edge appliances, and can be located on-premises or in the cloud. This controller can extract information from the individual appliances that it manages to make an intelligent decision on how the SD-WAN should react to changes in the overall WAN infrastructure or application traffic. Also, the controller synchronizes the time across the individual Talari appliance which are the end points in the SD-WAN. This time synchronization is a critical service since it allows for the easy correlation of data that is collected from multiple locations that comprise the SD-WAN.
- Talari appliances, which come in physical, virtual and cloud-based appliances can collect very granular information regarding the physical network, the virtual tunnels that link Talari appliances together and how applications that are traversing the network are performing. This approach eliminates the need to deploy probes or agents to determine how well the SD-WAN is performing.
- Talari Aware is a centralized management system for a Talari THINKING SD-WAN. Using Talari Aware reduces configuration time and errors while providing access to detailed performance data and events correlated across the WAN. This information is displayed on graphical maps and tables that are easy to read and highly customizable. Also, current and historical reports are available to support fault detection, troubleshooting, capacity planning, ROI analysis and SLA confirmation.
When combined, these capabilities deliver an easy to manage SD-WAN with unprecedented visibility into network quality and application performance. With this visibility, IT teams can make informed, strategic decisions about their network and service providers and tame the challenges associated with deploying, monitoring and troubleshooting an SD-WAN.
If you are interested in a customer’s perspective regarding the visibility and reporting that a Talari SD Thinking WAN delivers, take a moment to review the following quotes:
“I love the statistics that Talari generates. I use the data to get restitution from our service providers when we have outages. Sometimes the problem is in the provider’s network. When I pull up Talari reporting and analytics, I can see what’s happening. Otherwise, it takes a lot more effort to get the information. Talari simplifies troubleshooting as well as day-to-day management.
