Developers often face issues where code that works on their laptop breaks in production, leading to the birth of the DevOps movement.
The environment gap between development and production, including differences in node versions, operating systems, resource constraints, and missing environment variables, contributes to these problems.
Common issues include missing environment variables causing authentication failures, database engine mix-ups leading to syntax errors, and file path discrepancies causing file not found errors.
To address these challenges and improve deployment consistency, DevOps advocates for environment standardization through tools like Docker, Infrastructure as Code, CI/CD, and Configuration Management.
