Yes, this is a fabulous question and we as afficionados of Linux-on-zSeries and of VM should not be afraid of it. > So my question is: What moves are afoot to reduce the > number of required images by consolidating their > functions and remove the TCP/IP communications between > applications? I know that there are "moves afoot" from several sectors. My own employer has some offerings out there already. Then there are home-grown strategies which leverage zSeries and/or VM which are sometimes obvious (and sadly sometimes NOT obvious). Communication among Linux-on-VM instances can be through TCP/IP. But don't forget that even there the guest LAN has advantages over wired interconnect. ALSO don't forget that TCP/IP is not the only means of communication and resource sharing. -- R;
