Speech Title: Technical Considerations for Hybrid Cloud Deployment of Enterprise Information Systems

Abstract: Whereas it is widely accepted that cloud deployment of enterprise information systems can achieve an optimal cost-performance balance, the implementation method is subject to many factors such as usage pattern and information security as different deployment models have different benefits and limitations. This presentation discusses the technical considerations for hybrid cloud deployment of enterprise information systems, based on a successful case study. It is an enterprise information system which used to handle large volume of concurrent accesses and transactions at seasonal peaks. The system adopts a typical 3-tier architecture, comprising a web tier, an application tier and a database tier. Taking a hybrid cloud approach for cost-performance balance, the web tier and application tier are deployed on cloud with the back-end databases resided on premises. This essentially accommodates the largest flexibility in the system design such as on functional configuration and customization, while attaining an acceptable level of resilience and information security control. Different environmental settings is discussed to illustrate how an optimal cost-performance balance can be derived effectively.
