Red Hat delivers hardened, open source solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge.

• Integrated QUADS – an internal system used at Red Hat to share a common pool of hardware resources for scalability testing with HIL. Thereby increasing the capability of QUADS to manage wide variety hardware.
• Wrote Juniper driver for HIL to support production environment of QUADS at RedHat.
• Developed a OpenVswitch driver for HIL to support a continuous integration environment for virtual deployment testing for QUADS and HIL
• Did prelimnary work towards developing adaptable reservation system to be included in QUADS.

The Mechanobiology Institute (MBI) is a Research Centre of Excellence hosted at the National University of Singapore.
