Oracle database is one of most wanted skill perhaps until today. As far as I know, compared to its rivals such as MySQL and Postgres, its installation requires substantial effort. The application itself also draws huge memory and storage.
Today, Oracle is contained in a ready-to-use container. Only in minutes, an Oracle instance could be deployed. We can also store map the instance storage to our Dropbox. Therefore, we can flexibly run, stop, and destroy the instance in case extra storage space is needed without losing the data.
