Are there any known instances of a company dropping support for Oracle? My employer supported both Oracle and MSSQL for our now-legacy desktop offering but opted to support MSSQL-only when we rewrote for the cloud. Our testing and operations effort was reduced significantly and on-premise customers have dealt with those implications but I’d say it’s definitely a net positive for us.
Not saying that MSSQL is any better than Oracle, or Postgres for that matter.
Yandex did. Russia’s version of google. If you YouTube search “yandex postgresql” you will find them giving a talk about the wins for them in switching.
I’ve been waiting for Oracle to slowly die for 20 years. But they kee growing. Enterprise, once gained, is really hard to lose. Novell is still in business, as one example.
The article touches on this, but it’s a factor of new companies eventually growing up without needing Oracle. That could take 50 years.
Databases often house an organization's key data and related business logic. It's not trivial to port such over. PostgreSql is not 100% compatible, and testing and adjusting takes time.
That being said, an org should foster open-source RDBMS for new projects that don't need heavy data-sharing with Oracle instances, and slowly expand. For one, Oracle sales-people will give you better deals if they know you are nurturing alternatives within. It's better if Oracle has you by one nut instead of two.
I was once told by an IT manager of a supermarket chain, that no db was able to handle the high-volume of transaction they had during the peak hours. It was anecdotal without any hard proof and he did not want to get to the details as it will reveal their inner workings. They have 50 branches with each store having 30 counters.
