What Makes Legacy Systems Different
Legacy systems are old computer systems that businesses still rely on. They're outdated but crucial for daily operations.
Legacy System Basics
What defines a legacy system:
| Feature | Description | Impact |
|---|---|---|
| Age | 10+ years old | Doesn't play well with new tech |
| Architecture | Monolithic, closed | Hard to change or upgrade |
| Programming | Old languages (COBOL) | Few developers know it |
| Hardware | Mainframe-based | Expensive to maintain |
| Documentation | Often missing | Knowledge gaps |
Many organizations can't let go. In 2023, the US government spent 80% of its IT budget on these old systems.
Main Integration Problems
Adding AI to legacy systems is tough. Here's why:
| Problem | Example | Business Impact |
|---|---|---|
| Data Access | IRS's 2018 Tax Day crash | Lost processing time |
| System Load | Banks' transaction limits | Slower customer service |
| Security Gaps | Old protection measures | Higher breach risks |
| Cost Issues | 40-60% of CIO time on maintenance | Less innovation |
"Supporting a legacy operating system is about risk management as much as IT service management." - Vijay Samtani, CISO at Cambridge University
Some companies are making it work. American Express added AI to their old transaction system. They now spot fraud in real-time without replacing everything.
Walmart's doing it too. They've added AI to predict product demand while keeping their old supply chain systems.
Tools like Laminar help. They let teams connect to legacy systems without writing complex code. This saves time and reduces technical debt.
5 Steps to Add AI to Legacy Systems
Here's how to integrate AI with your old systems without breaking them:
1. Check Your Systems
