When an incident occurs, developers need to know what data to look at, where the incident occurred, and other relevant metrics. They also care about infrastructure: SREs require system visibility and incident management. In Grabner’s example, he understood that there was an increased Java error rate on the front end of the application.

However, one metric I feel that front-end developers overlook all too quickly is Time to First Byte (TTFB).

The common way to deal with this is to measure percentiles, and track the 90%, 99% response times for example. For example lets say you have a 99% within 2 seconds SLA, and your current 99%ile measured over one minute is 1 second. However it’s very difficult to decide what the right SLA is, or to tell how close you are to exceeding it.

Obviously, without the need to have to rent or buy physical servers, it can be more cost-effective for organizations to forego the traditional route of having to manage their physical infrastructure and only pay for the time and memory utilized to run your code/applications. The time it takes between an action and a response is latency.
