vtVAX is a replacement for old VAX hardware. The VAX/VMS or OpenVMS applications and Operating System run on vtVAX exactly the same as they ran on the old hardware. Your users see no difference in the application other than the system will be faster. Using vtVAX you do not need to compile your source code, just transfer the disks, boot and go.
Since vtVAX runs on modern, off the shelf, X86 hardware you do not have to spend hours searching eBay for used parts or paying a field service company hundreds or even thousands of dollars to have someone show up at your door who you hope might remember what a VAX looks like. Modern hardware also means that you CPU and I/O will be faster than any hardware VAX ever built.
There are two versions of vtVAX. One developed by Vere Technologies that runs on Windows, the other developed by AVTware that runs on "Bare Metal." The server that vtVAX runs on can be a standalone server or a virtualized machine or even in the cloud. Imagine your old VAX 6000 with disk drives bigger than a standard rack running in the cloud. To migrate your current system it is really as simple as configuring the virtual machine to look like your old hardware, use our disk migration tool to backup your old hardware to the new server, boot standalone backup, restore the backup on the virtual machine then boot. The passwords stay the same, the access stays the same, the applications stay the same. Nothing needs to be compiled or rebuilt.
