strace is simple to use and works well for issues such as "Why can't the software run on this machine?" According to a performance test conducted by Arnaldo Carvalho de Melo, a senior software engineer at Red Hat, the process traced using strace ran 173 times slower, which is disastrous for a production environment.

Chaos engineering is a method of testing distributed software that deliberately introduces failure and faulty scenarios to verify its resilience in the face of random disruptions. Practitioners subject software to a controlled, simulated crisis to test for unstable behavior. Chaos engineers ask why. Hypothesis.

In my previous article about continuous integration and continuous delivery (CI/CD) , I defined CI/CD and explained how these practices work together to help DevOps teams deliver quality software faster. For software to be delivered in a deployable state at all times requires that it be developed with that mindset.

It was the promise that they could deliver software faster, more frequently, and with higher degrees of quality, enabling the business to respond better to constantly changing customer demand. But when we first embarked on this journey, we looked like a very traditional software company: Two releases per year. Zero daily deployments.

Putting the user at the center instead of the software. You can almost think of it as software documentation in reverse. The result?

It’s not just a simple tweak you can turn on/off; it’s a long-time process that touches almost every single item in your stack, including both hardware and software sides of the system. Application scalability is the potential of an application to grow in time, being able to efficiently handle more and more requests per minute (RPM).

As such, a micro-optimization is, again, how you probably need to fine-tune things on a low level to really benefit from it. As such, many firewall vendors currently recommend blocking QUIC until they can update their software. Even then, however, validating protocol performance with the current generation of tools won’t be easy.
