Il s'agit d'une nouvelle version gratuite de mon Lightning Talk de la conférence Joker 2019. Depuis lors, plusieurs nouvelles versions de Quarkus ont été publiées, le rapport a été aligné sur l'état actuel des choses.
Dans le cadre du développement de notre plateforme CUBA Platform , nous accordons une grande attention à ce qui se passe dans l'industrie. Bien que le cadre CUBA soit construit autour de Spring, on ne peut ignorer ce qui se passe autour. Et, bien sûr, tout le monde a remarqué que ces derniers temps, il y a eu beaucoup de bruit autour des frameworks natifs du cloud . Deux nouveaux venus - Micronaut et Quarkus commencent avec confiance à pénétrer sur le territoire de Spring Boot. Un jour, il a été décidé de faire un petit RnD, dont les résultats dont je parlerai de l'expérience de travail avec le framework Quarkus l'exemple des applications bien connues - Petclinic .
