Stromasys legacy server emulation on Azure: Running applications designed for SPARC, Alpha, VAX, PDP-11, and HP 3000
If your organization is using legacy hardware, you know the risk and cost of maintaining it. A virtualized environment on Azure Virtual Machines can offer better performance, lower costs, and less risk for running a legacy software stack.
