Come si fa ad essere sempre online? Come si gestiscono i picchi di traffico previsti e imprevisti di un sito, e-commerce, blog o portale di informazione? Dalla vecchia infrastruttura server ad una soluzione cloud: nel nostro intervento vi mostreremo come creare infrastrutture a supporto di applicazioni web su un cloud OpenStack (Enter Cloud Suite) e vedremo quali sono i vantaggi in termini di sicurezza, di costi di gestione e di performance. Capiremo come gestire istanze cloud in un sistema europeo multiregion, come impostare snapshot, backup, storage, health check e load balancer e come gestire scalabilità e automazioni. Il talk è particolarmente indicato per sistemisti, DevOps e full stack developer che vogliono sviluppare soluzioni stabili, flessibili e sicure.
