Najlepsze praktyki w Kubernetes. Jak budować udane aplikacje

Brendan Burns, Eddie Villalba, Dave Strebel, Lachlan Evenson

Systemy informatyczne oparte na chmurze stały się atrakcyjną alternatywą dla standardowej infrastruktury. Wymusiły jednak radykalne zmiany w praktykach tworzenia, wdrażania i utrzymywania aplikacji. Dziś uwaga profesjonalistów skupiona jest na Kubernetes, który w ciągu zaledwie kilku lat stał się faktycznym standardem wdrażania natywnej chmury. Aby tworzone aplikacje funkcjonowały wydajnie, bezawaryjnie i niezawodnie, warto wdrożyć i stosować wzorce i najlepsze praktyki. Konieczne jest również przemodelowanie sposobu pracy programistów. Ta książka jest przeznaczona dla profesjonalnych użytkowników Kubernetes, którzy chcą poznać wzorce i najlepsze praktyki przy wdrażaniu rzeczywistych rozwiązań. Znalazły się tu informacje o jego działaniu w różnych skalach, topologiach i domenach, a także liczne przykłady zastosowania omawianych technologii.
