A company wants to use older business software that is incompatible with the current operating system on their employees' computers. The company needs a cost-effective way to provide access to this legacy application. Which of the following is the BEST solution?
Upgrade or rewrite the legacy software so it runs on the current operating system.
Dedicate physical hardware to install the legacy software natively.
Run the older operating system in a full software emulator instead of using virtualization.
Use a virtualization platform to create a sandboxed virtual machine for the legacy software.
Using a virtualization platform to create a sandboxed virtual machine lets the legacy operating system and application run in their native environment while keeping the host OS unaffected. This is typically cheaper and easier than buying and maintaining separate hardware or rewriting the software. Emulation without virtualization adds unnecessary overhead, and rewriting or upgrading the software may be infeasible or costly. Dedicated hardware requires additional capital and maintenance.
