Designing Scalable Storage System for Application Oriented Middleware – MidArc

Recent boom in Internet shopping, and e-commerce leads to large number of services available on the Internet. Many of these services require a set of basic functionalities in order to work. Basic functionalities include: user identification and authentication, access control, billing, and user profile management. Service programmers need to implement these functionalities repeatedly for each service implementation. MidArc application middleware implements basic functionalities and enables services to use them through interfaces, thus simplifes the service development process. Implementation of basic functionalities requires a robust storage system. Such storage system needs to offer satisfactory response times and a scalable architecture that allows upgrades. In this paper, we propose three designs of the storage system. The first storage system solution is based on a relational database, the second one uses combination of relational database and a directory, while the third one upgrades the second one with caches and buffers. All storage system solutions implement the same interface and can be used interchangeably. Performance measurements are conducted that compare the behavior of proposed storage solutions in diverse environments.
