5 Software Architecture Mistakes That Make Systems Hard to Change

This article discusses five common software architecture mistakes that lead to systems becoming difficult to modify over time. It highlights the critical error of selecting architectures, frameworks, and tools without first understanding the business domain, constraints, and actual problems. The author argues that expensive architectural decisions made prematurely add unnecessary complexity and technical debt. Examples include choosing microservices, event sourcing, or Kubernetes without clarity on business workflows. The article advises shifting focus from 'what architecture to use' to understanding the problem that justifies the decision. It is relevant to IT/technology professionals, especially software architects and developers, seeking best practices in system design and maintainability.
