Modernize mainframe applications faster using Amazon Q Developer (DOP221-NEW)

Here is a detailed summary of the video transcription in Markdown format, broken into sections for better readability:

Mainframe Modernization Challenges

• Mainframe applications are extremely large and complex, with millions of lines of code and interconnections.
• These applications often lack proper documentation, and modernizing them is a labor-intensive, multi-year process.
• Technical complexity, such as monolithic architectures and sequential code, makes it challenging to understand and disentangle functionalities.
• Organizational silos and a scarcity of Mainframe expertise further complicate the modernization efforts.

Amazon Q Developer for Mainframe Modernization
