Enterprise Architecture vs. Solution Architecture: A Unique Gist View
Enterprise architecture (EA) focuses more on IT strategies, values, directions, and associated capabilities. In contrast, solution architecture (SA) focuses more on an individual solution, with more considerations of technologies and platforms. Enterprise solution architecture (ESA) represents the essence of both EA and SA.

The Solution Context, Inward or Outward?
Solution context refers to the environment and conditions in which a solution is being implemented or considered. It encompasses various factors that influence the design, development, and deployment of a solution. Understanding the solution context is critical to ensuring that the solution is appropriate, effective, and sustainable in its intended environment. The concepts of “inward…

5C Area Model for Enterprise Solution Architecture (ESA), A Brief Introduction
For ease of recall, the A-ESA model can be simplified as a 5C or C5 model that captures the essence of the A-ESA areas. The 5Cs stand for Capability, Case (Scenario), (Solution) Context, Composite (Services), and Container (Environment). The 5C Area Model provides a holistic enterprise solution model for effective architectural thinking.
