Live Vertical Scaling for Big Data – Today!
You may have heard of Software Defined Networking: the concept of creating, maintaining, and evolving data-center wide networks based on VLANs and software configuration instead of physical (re-)wiring. One may apply the same core concepts of run-time configurability to actual servers, to the end-points connected via SDNs. Enabled by virtualization, a machine’s characteristics may be adjusted at run-time, e.g. to counter overload situations, or to change the role of a system on the fly.
