Observability across the full technology stack gives teams comprehensive, real-time insight into the behavior, performance, and health of applications and their underlying infrastructure. Observability can identify the baseline user experience and allow teams to improve it by optimizing page load times or reducing latency.

Real user monitoring (RUM) is a performance monitoring process that collects detailed data about a user’s interaction with an application. IT teams can deploy synthetic agents in different geographical regions, so you can detect variations in application performance based on geolocation. What is real user monitoring?

When an application is triggered, it can cause latency as the application starts. Performing updates, installing software, and resolving hardware issues requires up to 17 hours of developer time every week. Services tend to run on warehouse-scale computers meant more for edge applications than high-performance computing.

Because monitoring tends to focus on key indicators such as utilization rates and throughput, monitoring indicates overall system performance. 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.

Digital experience monitoring (DEM) allows an organization to optimize customer experiences by taking into account the context surrounding digital experience metrics.

With observability, teams can understand what part of a system is performing poorly and how to correct the problem. Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. Traces provide performance data about tasks that are performed by invoking a series of services.

With more standardised FOUT/FOIT behaviour from browser vendors, to the newer font-display specification, performance—and therefore the user—seems to have been finally been put front-and-centre. On this site, in which performance is the only name of the game, I forgo web fonts entirely, opting instead to make use of the visitor’s system font.

So, for the last several years, I, along with other performance engineers like me, have been recommending that our clients move over from Gzip and to Brotli instead. The uncompressed version, on the other hand, takes a full two round trips more to be fully transferred, which—particularly on a high latency connection—could be quite noticeable.

This week I’ve been brooding about web performance and accessibility. I’d like to say that this one AMP Story was an outlier, but each of the nine demos listed on the AMP Stories website sound just as incomprehensible in VoiceOver. And I couldn’t agree more; every loading screen and wait time is in some degree a mark of failure.

This provides organizations to scale out horizontally to provide better functionality and performance. This also includes latency, or the time it takes for data or a request to get through a network. Teams must ensure that they are also monitoring performance from the user’s perspective, as well as the system itself.
