Legacy systems are older software, hardware, or technologies
that are still used by an organization, although they could generally
be replaced by more modern and efficient solutions.
These systems are often deeply integrated into a company's infrastructure and processes,
making their replacement or modernization complex and risky.
Features of Legacy Systems:
- Aging Technology: Legacy systems often rely on technologies that are no longer state-of-the-art.
- High Maintenance Costs: These systems are often expensive to maintain.
- Difficult Integration: Legacy systems are usually hard to integrate with newer technologies.
- Data Isolation: Legacy systems often operate in isolated environments.
- Operational Risks: Since these systems are often no longer supported by the manufacturer, security risks can arise.
Importance of Legacy Systems:
- Critical Importance: Many legacy systems support critical business processes.
- Investment Protection: Companies have made significant investments in these systems.
- Migration Complexity: Migrating to more modern systems can be complex, costly, and risky.
