In occasione del Containers & Cloud-Native Roadshow 2019 il DevOps Engineer Fabio Fucci ha fornito una panoramica sui concetti chiave, sui benefici e sulle opportunità offerte dalle applicazioni cloud-native e da Red Hat OpenShift. I punti trattati durante la presentazione sono: - Dai monoliti alle applicazioni cloud-native - Le architetture a microservizi - Il percorso verso le applicazioni cloud-native - Cos’è un container? - Red Hat OpenShift - Costruire e rilasciare immagini per container - Cloud-native runtimes Per saperne di più, scaricate le slide e guardate il video della presentazione su https://www.par-tec.it/cloud-native-landscape-review
