Technology Lead, Infosys Limited (July 2013 to October 2022)
Moved physical Windows file servers onto virtual machines on VMware vSphere as part of the data centre consolidation.
File services ran on physical servers that took space, power and maintenance, and were harder to protect than virtual machines.
Each file server was moved to a virtual machine on VMware vSphere, with cutover planned inside change windows so users kept access to their shares.
File services run on the virtual platform with the rest of the estate, on less physical hardware.
Migrated, consolidated and modernised infrastructure across 7 US sites and 6 global data centres: over 150 ESXi hosts and over 1,500 Windows servers.
Designed and administered Exchange 2013, 2016 and 2019 hybrid with DAG alongside over 70,000 Microsoft 365 mailboxes at 99.5 percent uptime.
A repeatable patching process for servers and end-user devices that met compliance deadlines and closed an audit gap.
