I have been working with virtualization and its infrastructure for the last 6 years. This includes all infrastructure aspects: servers, networking, storage. I’ve designed and deployed virtual infrastructure for realtime services of my current company (GMA Group). This is some about 150 virtual servers (telephony softswitches, databases, web production servers) for different company’s projects, that are placed on blade server’s physics with SAN in two datacenters in different countries but with shared virtual environment based on vmWare vSphere. It gives me the possibility to load balancing not only between hosts but datacenters.
