The New 3-Tier Architecture: HTML5, Proxies, and APIs
Download as PPTX, PDF16 likes27,123 views
The document discusses the evolution of web application architectures from traditional 3-tier to a new 3-tier architecture in response to the rise of mobile and APIs. The new architecture places a proxy tier between the presentation and API tiers to address issues like authentication, authorization, and cross-origin resource sharing when APIs are not fully controlled. The proxy tier can also help reduce logic bloat in the presentation tier by moving technical concerns. Starting with the presentation tier, leveraging available APIs, and using the proxy tier to address blockers and move logic are recommended for getting started with the new architecture.
