Layered Architecture: Systems in Tiers
For a time I was on an ARB (architecture review board), and was tasked to review and help teams in their cloud migration journey. One of this teams spent some months moving a monolithic application to the cloud, only to discover they’d essentially recreated their on-premise three-tier architecture in the cloud. Initially everyone was disappointed that the new project wasn’t using the latest architecture patterns, but the truth is that, for the problem that system was solving, the layered architecture was the best solution.

Beyond the Monolith
While our previous exploration of monolithic architecture showed the power of unity, layered architecture demonstrates the power of purposeful separation. But we’re not talking about code organization here — we’re talking about system-level tiers that can be deployed, scaled, and managed independently.
