My DDD and Portfolio Architecture Playlist

Playlist

• Neal Ford's DDD playlist
  • Neal gets first spot as he came up with the idea first of a "reading list" referencing a single chapter, instead of the whole book
• Building Microservices - chapter 2
• Learning Domain-Driven Design - chapter 1
  • the business centric comparison of core VS generic sub-domains is interesting. (generic sub-domains as an area where a business may choose to outsource a specific function)
• Accelerate - foreword by Courtney Kissler
• I found Courtney's foreword the most compelling reason to read the rest of the book
