Hi Olga, At the moment Flink does not have any embedded support for multi region deployment or failover. You can try to automate it, for example, using savepoints [1] and backing them up in multiple data centres. This way you could restore failed job in other regions from the latest savepoint. Of course, job input/output should be also available in multiple data centres.
Flink does not have any embedded encryption mechanism for state. The state value is just de-serialisable byte array for Flink. For example, you can implement custom TypeSerializer [2] or wrap existing one with encryption.
