Before Docker, developers faced inconsistent environments leading to the infamous "It works on my machine" syndrome, along with complex dependency management across teams and systems. This resulted in slow deployments, difficult scaling, and frequent bugs specific to different environments.

Problems Before Docker

• Inconsistent environments: 'It works on my machine' syndrome
• Complex dependency management across teams and systems
• Slow deployments and difficult scaling processes
• Frequent environment-specific bugs and failures

This slide highlights key benefits for developers and teams using containerization, including fast deployments with Docker, easy scaling via CI/CD pipelines, and isolated environments that prevent dependency conflicts. It also emphasizes eliminating "works on my machine" bugs through reproducible setups and cost savings from efficient resource optimization.
