Legacy Applications
Your Legacy Applications – How to Keep Them Alive Without Risking Disaster
Are your applications still running on old operating systems?
You’re not alone. Many organizations have no choice but to maintain critical software developed more than 15 or 20 years ago—whether tied to production systems, expensive licenses, or simply because rewriting them today would cost a fortune.
Running old hardware or an unsupported operating system (OS) in direct production is like driving a vintage car on the highway every day. Sooner or later, it will break down. Worse, spare parts are no longer available.
Let me introduce you to the Legacy1 Services Integration Platform.
A bit of context
These older applications often only run on operating systems that are no longer supported—or are at end of life.
The problem: these old OS versions, no longer supported by their vendor, haven’t received security updates in ages. Exposing them directly on the network becomes a guaranteed risk.
The solution: virtualize them in an isolated and controlled environment.
Why this is beneficial
- Strong isolation: your legacy applications are installed and run on a dedicated virtual machine (VM), fully separated from the rest of your infrastructure.
- Restricted access: only authorized users can reach them through a private and secure connection.
- Quick backup & restore: before each update or risky change, a VM snapshot is created, allowing you to roll back in just minutes if something goes wrong.
The result: you maintain compatibility with your legacy software without exposing the company to unnecessary risks.
Key features of a Legacy VM
- Deployment of OS instances (e.g., Windows XP/2003) optimized for your application.
- Instant snapshots acting as a safety net to quickly restore the environment if problems arise after an update.
- Legacy applications exist and operate within an isolated VLAN, completely segregated from your modern systems.
In other words
Digital transformation doesn’t mean throwing everything away.
There are smart ways to integrate the old with the new—without neglecting security, performance, or digital sovereignty.
At DATAenligne, we help our clients create environments where even the oldest software still has its place—without putting their future at risk.
Thanks to our expertise in Private Cloud, we design flexible virtualized infrastructures that allow organizations to move step by step through their digital transition while progressively modernizing their applications.
The result: a secure and high-performance environment, capable of supporting both your legacy systems and your new solutions.
Do you have a Legacy application that refuses to evolve?
