Although the most sensitive layer of the infrastructure stack, the database layer has the potential for the greatest cost savings and strategic advantages. For example, one Oracle license alone lists at $47,500 per processor core (without any add-on features) with annual operating expenses equal to 22% of the total license costs. Implementing Postgres is a wise alternative to Oracle’s business practices and price increases. Not only does this reduce capital and operating expenses, but IT vendor flexibility also increases.
