This blog series will examine the tools, techniques, and strategies we have utilized to achieve this goal. In this testing strategy, we execute a copy (replay) of production traffic against a system’s existing and new versions to perform relevant validations. This approach has a handful of benefits.

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.

This includes development, user acceptance testing, beta testing, and general availability. connectivity, access, user count, latency) of geographic regions. The result is a more comprehensive and robust monitoring strategy that will have a longer-lasting impact on user performance and experience. The bottom line?

Taiji’s routing table is a materialized representation of how user traffic at various edge nodes ought to be distributed over available data centers to balance data center utilization and minimize latency. For example, balance utilisation across all data centers, or optimise for network latency. Sharing is caring caching.

There are many possible failure modes, and each exercises a different aspect of resilience. Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. This is why most AWS regions have three availability zones.

1:18pm a key observation was made that an API call to populate the homepage sidebar saw a huge jump in latency. The shop had been closed so no data was available. The process tracing exercise included: Examning IRC transcripts from multiple channels. Gathering timestapms of changes made to application code during the outage.
