These releases often assumed ideal conditions such as zero latency, infinite bandwidth, and no network loss, as highlighted in Peter Deutsch’s eight fallacies of distributed systems. In this blog post, we delve into these challenges and explore how Dynatrace can address them to enhance the reliability of released software.
