Transforming an application from monolith to microservices-based architecture can be daunting, and knowing where to start can be difficult. Because monolithic applications combine database, client-side interfaces, and server-side application elements in a single executable, they’re difficult to understand, even for their own administrators. Today’s customer expectations can’t tolerate tightly coupled dependencies, difficulties deploying changes, or long release cycles.

Memory is a relatively scarce resource on many consumer computers, so a feature to limit how much memory a process uses seems like a good idea, and Microsoft did indeed implement such a feature. However: They didn’t document this (!) Their implementation doesn’t actually save memory The implementation can have a prohibitively high CPU cost This feature works by limiting the working set of a process – the amount of memory mapped into the address-space of the process – to 32 MiB.

Elasticsearch is an open-source search engine and analytics store used by a variety of applications from search in e-commerce stores, to internal log management tools using the ELK stack (short for “Elasticsearch, Logstash, Kibana”). As a distributed database, your data is partitioned into “shards” which are then allocated to one or more servers. Because of this sharding, a read or write request to an Elasticsearch cluster requires coordinating between multiple nodes as there is no “global view”

Your team celebrates a success story where a trace identified a pesky latency issue in your application's authentication service. A fix was swiftly implemented, and we all celebrated a quick win in the next team meeting. But the celebrations are short-lived. Just days later, user complaints surged about a related payment gateway timeout. It turns out that the fix we made did improve performance at one point but created a situation in which key information was never cached.
