ABSTRACT: Space-Based Architecture and the End of Tier-Based Computing

Most business applications are architected using a tier-based approach (presentation, business logic, data tier). The emergence of powerful and new commodity HW and the introduction of SOA/Grid architectures touts the promise of achieving true linearly-scalable systems at a lower cost. However, as we shall see in this presentation, these new platforms and architectures are not aligned with the existing tier-based approach, which is by definition centralized and static.

During the presentation, a new approach will be introduced – Space Based Architecture (SBA). It is basically a combination of Distributed Caching, SOA and Grid concepts combined into a single coherent architecture optimized for high-performance data-intensive applications, which transforms existing tier-based applications into linearly and dynamically scalable services. Towards the end we will also discuss a real-life example of a financial application that was built using the SBA. We will explore the patterns used to achieve this goal and explore how it can be applied to other applications with similar requirements.
