總結本論文的系統架構，此系統使網頁容器 (Container) 更具模組化，並使 其成為一個提供網頁表達的網路服務。也因為經由網頁表達服務的提供，能夠 達到將重要的後端服務被隱藏，對於企業內部的整合或是與外部的合作都將能 提供另一個選擇的方案。此外，經由這樣的分散式架構，網頁開發的工程可以 被分散，且因為部份的網頁開發責任被交予後端服務的特定領域的開發者，可 以達到更適當的分工，提昇網頁的開發效率。而這些分散的網頁表達服務，就 跟後端服務一樣，經由以 XML 為基礎的溝通協定為介面來互相合作，最後把 完成的網頁內容傳送給網頁瀏覽器。
除了達到良好的分工之外，文中並提出了為了達到本論文的目標而需要應付 的議題。藉由提供這樣的網頁表達服務，可造就出表達層的商業市場，而可將後 端的服務包裝隱藏起來。
未來仍會在效能的考量上著手，在服務間的溝通上求取最佳化，並實作更多 的應用實例。並且將本論文的網頁表達架構能跟其他技術，如 JSP，Struts 等達 成整合，採用現有不同的樣版語言和熟悉的 MVC 開發架構，以利用已存在且被 普遍使用的技術與資源。
