Pros
Oracle Cloud Infrastructure is trying to differ itself from the Oracle Monolith. It prides itself on delivering fast, having a different set of values, and growth. It also is showing a lot of promise in it's design departments. Oracle is starting to really embrace design culture, which is a significant shift from past history.
Cons
Oracle Cloud Infrastructure has been scaling at a rampant pace. It has a lot of maturing of basic services, internal and external, that you would expect from a large enterprise company. Oracle is still very dogmatic. It is an IT business and does not treat its IT department as a business. A lot of Oracle's internal tools are out of date and so owns a huge IT tech debt. It actively chooses to not use the most efficient options available on the market, just because they are not in Oracle's portfolio. Legal and compliance is also a shadow that looms over development.
