Network Observability

Distributed client-server applications, mashups and microservices running on top of modern networks are large distributed systems. A significant amount of conversational (and in some cases, practical) energy has been expended in addressing the configuration problems of such systems. However, little has been addressed when it comes to observability of such systems, specifically the networking piece.

In this webinar, we'll discuss what is observability, how its different from monitoring, and why this matters. While the ideas and concepts presented have broad applicability, the author's own familiarity with the data center space, implies that examples and anecdotes will be more data-center specific. For example, the implications of EVPN on observability, while specific to the data center (and VXLAN), may be applicable in other areas where overlays are used.

We will examine how network architecture and judicious use of modern technologies can help observability. We'll cover different models of network observability, look at some toolkits - old and new - and conclude with a discussion of a prototype for an open source observability platform and application.
