VMware just published the second VMware Technical Journal. This winter edition contains great publications on topics like vProbes, Paravirtual vRDMA Devices, Cloud Tenant UI design process, Storage DRS and FrobOS. There is also a nice introduction by VMware’s CEO Pat Gelsinger. Simply to much to mention, I suggest you just download it… I think it is a great read and it gives an idea about some of the things VMware engineers work on.
