Digital experience monitoring is the practice of using tools and technologies to gather and evaluate metrics as a customer navigates an application to determine the quality of a user’s interaction with its digital touchpoints.

Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. Observability platforms are becoming essential as the complexity of cloud-native architectures increases. Observability is made up of three key pillars: metrics, logs, and traces. Watch webinar now!

For example, when monitoring a database, you’ll want to know about any latency when writing data to a disk or average query response time. Distributed tracing is a way of observing requests as they move through distributed cloud environments. True observability, however, relies on more kinds of data than just key indicators.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. It was a great privilege. Ford, et al., “TCP

With the rapid advancements in web application technologies, programming languages, cloud computing services, microservices, hybrid environments, etc., We all know that there is no such thing as a perfect system and there is a tradeoff for every decision made, especially in cases where complex, modern technologies are involved.

Traditional CMS is a dead end In the last 5 years, traditional CMS landscape is not evolved much - both CMS technologies as well market maturity remains unchanged. Although some vendors have added support for APIs and cloud services most have not even bothered to adapt with changing technology landscape.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms.
