We then used simple thought exercises based on flipping coins to build intuition around false positives and related concepts such as statistical significance, p-values, and confidence intervals. As a result, if the test treatment results in a small reduction in the latency metric, it’s hard to successfully identify?

Over the course of this post, we will talk about our approach to this migration, the strategies that we employed, and the tools we built to support this. Functional Testing Functional testing was the most straightforward of them all: a set of tests alongside each path exercised it against the old and new endpoints.

There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. STPA is based on a functional control diagram of the system, and the safety constraints and requirements for each component in the design.

1:18pm a key observation was made that an API call to populate the homepage sidebar saw a huge jump in latency. The process tracing exercise included: Examning IRC transcripts from multiple channels. Members of the team begin diagnosing the issue using the #sysops and #warroom internal IRC channels.

With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. In that spirit, what we’re looking at in this article is focused more on the incremental wins and less on providing an exhaustive list or checklist of performance strategies. Again, every millisecond counts. Lighthouse.

Service-oriented architecture (SOA) was hyped in the mid-2000s as a modern take on distributed systems architecture, which through modular design would provide productivity through loose coupling between collaborative services—so-called "WebServices"—communicating through externally published APIs. of ( Invoice. alsoTo ( Sink. of ( Order.
