What Hacker News says?
Actually you can avoid having a separate DB! You can build a materialized view of the data using [KTables]( https://developer.confluent.io/courses/kafka-streams/ktable/ ) or use [interactive queries]( https://developer.confluent.io/courses/kafka-streams/interac... ). The "table" is built up from a backing kafka topic so you don't need maintain another datastore if the data view you want is entirely derived from one…

HN discussionAnswering your technical question: Some companies let you deploy their "building blocks" onto multiple clouds (you typically choose the exact region/availability zone), and then also allow you to build proper multi-cloud deployments. There is usually no switch to flip, but these deployments (if properly setup) should tolerate if one region/cloud goes down. Two examples from the top of my head: Confluent Kafka: https…
