Microservices are contrasted to a monolith. Single, large application that implement the whole system. Typically hard to understand, develop, test and deploy. Monoliths tend to become a big ball of mud with each component referencing every other. The idea behind microservices is to split your complex system into multiple independent applications. Small and agile. They communicate with each other via APIs but are otherwise highly decoupled. The independence and decoupling has many aspects: deployment, languages and frameworks, storage, organization. Most importantly, each microservice should be self-sufficient to a reasonable degree.

Jest to odcinek podkastu:
Around IT in 256 seconds
Podcast for developers, testers, SREs... and their managers. I explain complex and convoluted technologies in a clear way, avoiding buzzwords and hype. Never longer than 4 minutes and 16 seconds. Because software development does not require hours of lectures, dev advocates' slide decks and hand waving. For those of you, who want to combat FOMO, while brushing your teeth. 256 seconds is plenty of time. If I can't explain something within this time frame, it's either too complex, or I don't understand it myself.
