| Data centers are the most critical infrastructures of companies and they are demanding higher and higher levels of quality of service (QoS) e.g., availability, scalability... At the core of data centers we find multi-tier architectures providing service to applications. Current infrastructure for multi-tier systems has focused exclusively in providing high availability using replication. Most approaches replicate a single tier, becoming the non-replicated tier a bottleneck and single point of failure. In this paper, we present a novel approach that provides availability and scalability for multi-tier applications. The approach lies in a replicated cache that takes into account both the application server tier (middle-tier) and the database (back-end). The underlying replicated cache protocol fully embeds the replication logic in the application server. The protocol exhibits good scalability as shown by our evaluation based on the new industrial benchmark for J2EE multi-tier systems, SPECjAppServer. | |
