One is the currently-running production environment receiving all user traffic (let’s say the “blue” one), the other is a clone of it (“green”), but idle. The new version of the application is deployed in the green environment and tested for functionality and performance. Response time for blue/green environment traffic.

These development and testing practices ensure the performance of critical applications and resources to deliver loyalty-building user experiences. RUM, however, has some limitations, including the following: RUM requires traffic to be useful. For example, in e-commerce, you can validate and test checking out a shopping cart.

For example, ghost code - code that is not commented out but will conditionally never be executed - is likely to be confused for real code in a reverse-engineering exercise. A clone of something extinct - our lost business knowledge - runs the risk of suffering severe defects. The facts are fantastic to have, but facts are not knowledge.

Even if you don’t end up with bugs, you could end up generating unnecessary network traffic by returning columns that the application doesn’t really need. Now this could be a really interesting exercise in patients to hit F5 repeatedly until you get two different values. The application could end up with bugs.

After a new build gets deployed and automated tests executed, SLIs are evaluated against their SLOs and, depending on that result, a build is considered good (promoted) or bad (rolled back). “ The app description and supporting files such as load testing scripts are on the Keptn Example GitHub.

New models are tested online through an A/B testing framework to compare their performance to previous generations. It wasn’t a wasted exercise though: The value of the whole exercise was that it validated that the entire NN pipeline was production ready and capable of serving live traffic. The time is right.

The ‘controlled’ part is important here because given the scale and complexity of the environment under test, the only meaningful place to do this is in production with real users. a bug fix, configuration change, new feature, or A/B test).

There are many possible failure modes, and each exercises a different aspect of resilience. In the same way that we have moved from a few big software releases a year to continuous delivery of many small changes, we need to move from annual disaster recover tests or suffering when things actually break, to continuously tested resilience.
