RE: [OffTopic] Curiosity about vision of the future for dba oracle ...

Hey guys,
i am sorry but i disagree.

_at_ Mladen: Sure - adding more CPU or memory will give more resources to execute other stuff but it won't necessarily make your slow SQL statement processing (due to inefficient exec plans / data access) faster. Why should anybody pay for more and more resources (as data has the tendency to grow) just because of inefficient execution plans or SQL processing. Care about your SQL and application implementation / code and it will save you a lot of money (especially in cloud) and time. Cloud does not change anything here. So IMHO your statement "Cloud makes it easy to just add more memory and CPU and not bother with trifle things like optimizing your SQL for performance." is not true :)

_at_ Mark: Sure - hardware providers and cloud vendors want to sell you hardware and/or computing time but this does not mean that this make sense (from a technical and business/economical point of view). If you go down this "simple hardware road" you will face some things like this very soon: "We’re starting to see a reverse cloud trend, Strohmeyer says. CIOs who were once excited to save on the capital expense of building or leasing more of their own data centers are now starting to see the long-term impact of the operating expense costs for things like Box, Amazon Web Services, or Microsoft. That stuff starts to get really expensive so they’re now looking at which workloads they can host cheaper themselves and which are best suited to the cloud, Strohmeyer says." - http://fortune.com/2017/09/13/amazon-microsoft-google-sap-cloud/

Then the last remaining bastion of full service experience DBAs comes into play and the most resource consumptive and elongated response time bits of the software and hardware stack are corrected.
