Dev/Prod parity

The difference between dev and prod environments, how to use third-party services, and changes need to be introduced to team structure and developers’ mindset.
Emulate similar local and production environment.

Logs

Log processing.
The Cloud Foundry approach to working with logs: Elasticsearch/Logstash/Kibana (ELK).
Send logs to ELK and read values on the dashboard.

Admin processes

Why using a unified approach when working even with minor changes?
An example with Liquibase
