    I wonder if the speaker realizes the irony of mistakenly using the Oracle Exalogic machine as the "straw man" in her presentation. While she suggests that Exalogic is for running the Oracle database, a 10 second Google search would have clued her in that Exadata is the Oracle database machine.

    Exalogic, on the other hand, was built to run middleware like Oracle Coherence (see ), which is the HA elastic scale-out K/V & document NoSQL data store that predates Dynamo by several years, dynamically scales to many terabytes of in-memory data, and (speaking of latency) is around 3 orders of magnitude faster than the numbers that were published about Dynamo.
