What are older software programs that still require specific environments to operate called?

Legacy applications refer to older software programs that were developed using outdated technologies or programming languages and thus require specific environments or platforms to function properly. These applications often rely on particular operating systems, databases, or hardware that may not be compatible with modern systems.

In a cloud environment, legacy applications can present challenges for organizations, as migrating them to newer, cloud-based architectures may require significant effort or even complete reengineering. Understanding the implications of legacy applications is critical in cloud computing as organizations seek to modernize their infrastructure and take advantage of new technologies while managing these older systems effectively.

The other terms listed refer to different concepts. A web farm is a group of servers that host applications or websites, usually to ensure scalability and availability. A geographically dispersed service refers to services that operate across multiple locations to reduce latency and improve redundancy. Malware is malicious software designed to harm or exploit devices and networks. Thus, legacy applications specifically align with the concept of older software requiring unique environments for operation.
