Legacy Applications
Are your applications still running on old operating systems?
You are not alone. Many organizations have no choice but to maintain critical software, developed more than 15 or 20 years ago, because they are linked to production systems, expensive licenses, or simply because it would be too costly to reprogram them to modern standards.
Be aware that 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, no spare parts are available today.
Let us introduce the Legacy service integration platform1.
Some Context
Old applications that run, for example, only on operating systems that are no longer supported or are end-of-life.
The problem: these old or end-of-life OSes are no longer supported by the vendor and, in some cases, have not received security updates for ages. Exposing them directly on the network would therefore become a guaranteed risk.
The solution: virtualize them in an isolated and controlled environment.
Here’s why it’s advantageous
- Strong Isolation: your old applications are installed and run on a dedicated virtual machine (VM), completely separate from the rest of your infrastructure.
- Limited Access: only authorized users can access them through a private and secure connection.
- Fast Backup & Restore: before each update or any risky operation, a copy of the VM (snapshot) is made to allow reverting in minutes in case of a problem.
Result: you maintain compatibility with your old software without exposing the company to unnecessary risks.
What are the key features of a Legacy VM?
- Deployment of OS instances (e.g., Windows XP/2003) optimized for your application.
- Instant snapshots that act as a safety net to quickly restore the environment in case of a problem after an update.
- Your Legacy applications exist and operate within an isolated and compartmentalized VLAN network, without direct contact with your modern systems.
In other words
Digital transformation does not mean throwing everything away.
