Software architecture for complex Web Applications

Author: Alexander Tretyakevich

Architectural Goals

The application architecture should address the following goals:

  • Provide for sufficient level of the performance for a specific subsystem/business feature
  • Be scalable to meet the needs for different lifecycles of the application (small at the start/growing as the popularity of the system will grow)
  • Be effective (scaling of a specific feature shouldn’t require scaling of the entire system/global change of the application deployment environment)
  • Be maintainable

 

Top-level Architecture Definition

The application architecture will be based on a service-oriented architecture concept, with both vertical and horizontal partitioning of services (depending on the nature of each specific service).
