In the olden days, users were in offices and all apps lived in on-premises data centers. The WAN (wide area network) was what connected all of them. Today, with the adoption of SaaS apps and associated dependencies such as cloud services and third-party API endpoints, the WAN is getting stretched beyond recognition. In its place, the internet is directly and exclusively carrying a large — if not majority — share of all enterprise traffic flows.
Enterprises are increasingly moving away from legacy WANs in favor of internet-centric, software-defined WANs, also called SD-WANs or software-defined networking in a wide area network. Architected for interconnection with cloud and external services, adopting SD-WANs can play a critical role in making enterprise networks cloud-ready, more cost-efficient and better suited to delivering quality digital experiences to customers and employees at all locations. But the transformation brings new visibility needs, and ensuring that SD-WAN delivers on expectations requires a new approach to monitoring that addresses network visibility and application performance equally.

If you were to put application and network teams into a single room and ask them if ensuring optimal application performance and availability for their end users was critical to the success of their companies, you would undoubtedly have all heads shaking yes. The question, of course, is how?
Many of us have lived through war rooms urgently called in response to degraded customer experiences, due to a performance or availability problem with a key application. Today’s modern applications are more distributed and modular than ever before, so not only has the number of stakeholders increased, but the lines of demarcation have also become blurred — causing confusion over responsibilities. Managing and optimizing application performance today is dependent on an increasingly complex underlying network and internet infrastructure that traditional application monitoring solutions fail to bridge, leaving visibility gaps for DevOps and NetOps to struggle with.
These heterogeneous environments introduce changing conditions that are sparking new tactics to manage the application experience; and monitoring is one of Continue reading
