Here is a brief summary of what the new video will cover based on your requirements:

• Failovers & Disaster Recovery (DR): Strategies for mitigating single-region constraints by relying on active copies of the digital state in local on-premises read-stores (PostgreSQL/Redis), ensuring that if the cloud region goes down, your users can still access their data.
• AI Integration & Bank Approvals: How to securely connect the cloud-exclusive Amazon Bedrock AI agent with relational databases and the legacy mainframe using strict VPC boundaries and API Gateways. It will also touch on how to navigate the bank's strict compliance, data sovereignty, and product approval processes.
• DDD & The COBOL Bottleneck: Best practices for applying Domain-Driven Design (DDD). The video explores how an Anti-Corruption Layer (CBS Gateway) cleanly maps and divides modern event payloads from strict legacy formats, ensuring the fast-moving modern developers don't bottleneck the legacy COBOL programmers.
• CI/CD Pipeline Separation: Best practices for securely dividing your code progression across Dev, Pre-Prod, and Prod environments to ensure zero-downtime deployments and isolated testing.
• Costs, Licenses, & Resource Calculations: A deeper dive into the financial engineering of your alternatives. I also went ahead and calculated your developer resource burn rate for the 1-year MVP timeline: managing 60 modern Java/AWS developers alongside 5 legacy COBOL developers yields a total team of 65, which equates to exactly 780 developer-months of effort over the year.
