Cross-Platform Virtualization Solutions: What They are, When to Use Them, and How They Benefit Legacy Systems

Articles

Technology is growing rapidly, leaving legacy hardware at risk of obsolescence.

Yet, for many organizations, legacy operating systems and applications remain critical for daily operations.

Imagine being able to run these applications (unchanged) without needing the underlying hardware. With cross-platform virtualization, this is entirely possible.

Additionally, it lowers costs and facilitates a seamless transition to modern IT infrastructure.

In this article, we will explore cross-platform virtualization in depth, explaining how it works, when to consider it, and the problems it solves. We’ll also highlight Stromasys, the leader in this space, to showcase how this technology is transforming legacy system management.

What Is Cross-Platform Virtualization?

Put simply, cross-platform virtualization makes it possible for software written for specific hardware and operating systems to run unmodified on completely different hardware.

This is done through a combination of dynamic binary translation and operating system call mapping. A virtualized environment is set up to allow the legacy software to function without any changes.

The best part? This frictionless approach eliminates the need for expensive and risky application rewrites. Organizations can move from older legacy technology to new hardware without disruption.

In other words, cross-platform virtualization ensures uninterrupted business continuity without sacrificing familiar processes.

Imagine using modern servers to run software originally built for discontinued architectures. And they are working seamlessly. That’s the power of cross-platform virtualization.

How Does Cross-Platform Virtualization Work?

Wondering how your old software will still run on the new platform? Let’s break down this process and its technical foundations.

The Abstraction Layer:

Cross-platform virtualization creates a clever abstraction layer that handles two critical functions: translating CPU instructions and managing operating system calls. Imagine an invisible bridge that allows software to think it is running on its original platform.

Dynamic Binary Translation:

At its core, this technology performs real-time translation of instructions. When software asks for something in its native language (guest instruction set), the virtualization layer quickly interprets these commands into something your current CPU (host) understands.

Think of it as an instant translator working at machine speed.

OS Call Mapping :

Software constantly commnunicates to operating systems through system calls. These requests handle essential functions like reading files or connecting to networks.

The virtualization layer intercepts these calls and redirects them appropriately. Your legacy application requests information in its traditional format, but these requests are converted into terms that your current system can interpret.

Business Benefits of This Approach:

For companies with legacy systems, this approach is a lifesaver. No need to rebuild or port applications. This saves substantial time and resources that would otherwise go into redevelopment.

• It provides a temporary bridge during transition periods, keeping critical operations running while you develop long-term migration strategies.
• It offers sustained support for legacy applications when the performance impact is minimal on your current hardware.

Every good thing has its flaws. Likewise, cross-platform virtualization has some performance overhead. But modern hardware typically compensates for this slowdown, making it a non-issue in many cases.

For optimal results, many implementations now leverage hardware acceleration to minimize any performance penalties.

When Should You Consider Cross-Platform Virtualization Solutions?

Cross-platform virtualization may be a good choice when your business-critical applications run on hardware that has reached the end of life.

Check out if your organization resonates with the following challenges:

• Outdated Hardware: outdated legacy hardware increases the likelihood of unexpected downtime, which can be damaging to business operations.
• Rising Maintenance Costs: older equipment drives up costs for breakdowns, replacement parts, and special skills.
• Energy Inefficiency: legacy servers use many times more power and cooling.
• Limits Scalability: these servers are not made to withstand current business requirements, such as cloud computing. They also introduce a great deal of complexity in the data center.

Now that you know whether you are facing these challenges, if so, seek out experts who provide cross-platform virtualization solutions.

Frequently Asked Questions (FAQs)

1. What are cross-platform solutions?

A cross-platform solution is software that allows you to run applications on multiple operating systems or devices without rewriting the application for each OS.

2. What is a virtualization solution?

A virtualization solution lets you create virtual computers (called virtual machines) inside one physical computer. This means you can run multiple separate systems on one machine, saving space and resources.

3. What is a virtualization platform?

A virtualization platform is software that allows you to create, run, and manage virtual machines (A virtual machine acts like a separate computer). This platform controls how these virtual machines share physical hardware.
