Who are these people that Simon Sharwood refers to as those "widely considered" in opinion re: his statement "..... the Hyper-V and attendant virtualisation management products available with Windows Server 2012 widely considered to rival VMware’s offerings."? Pure Bunk on his part.
Very recently a collegue has stated emphatically that technology officials from several large corporations, including Oracle, Cisco, several financial service firms and even companies like Amazon consider VMWare to be significantly superior - in features, functionality, performance and most especially reliability to Microsoft Hyper-V products.
Mr. Sharwood would therefore need to clarify and support his vague claim, less he be discovered and branded by credible and knowledgeable technology public as a Microsoft propagandist or worse their dupe.
