Data in microservice-based environments can be difficult to manage at scale. When application servers scale to near infinity, the datastores can't necessarily expand to meet that demand; they can only be optimized to keep up, and perhaps sharded. Considering just how much enterprise information is stored in some of those large systems, it's a worrying proposition to be asked by management to increase application performance when much of it is tied to an Oracle or Microsoft database.
Surya Varanasi, CTO of Vexata, has been dealing with large amounts of data for over a decade, now. While he once worked around the hardware layer at Brocade, today he focuses very heavily on the enterprise databases that power businesses around the world. From Oracle, to SAP, to SAS, and Microsoft, Vexata swims in a decidedly enterprise pool of customers.
