From InfoWorld: Amazon has spent more than a decade trying to free itself of Oracle’s “one database to rule them all” approach, something Amazon snidely calls “clunky” and “old guard.” Not content to unshackle just itself, Amazon has announced a series of database introductions and improvements to broaden choice for its customers. Yes, with Oracle you can get “fries” (MySQL) with your “burger” (Oracle DB). But with AWS you get a seemingly endless buffet of database options.
Well, you get 15 as of today, which feels like the equivalent of “endless” in old-school enterprise groupthink. At AWS Re:Invent 2018 today, the company announced three major functional upgrades to existing databases and two brand-new databases, bringing the full complement of purpose-built AWS databases to 15.
As Amazon CTO Werner Vogels wrote earlier in 2018, AWS offers “so many database products” because “developers want their applications to be well architected and scale effectively. To do this, they need to be able to use multiple databases and data models within the same application.” He continues:
"Seldom can one database fit the needs of multiple distinct use cases. The days of the one-size-fits-all monolithic database are behind us, and developers are now building highly distributed applications using a multitude of purpose-built databases. Developers are doing what they do best: breaking complex applications into smaller pieces and then picking the best tool to solve each problem. The best tool for a job usually differs by use case."
