Abstract: The process of moving business to the Internet through e-commerce solutions seems to have gained unstoppable momentum. We believe, however, that the success and pace with which business services will migrate to the Internet will be dictated by the ability to provide them with dependability guarantees. In this short paper we survey the progress we are making towards providing fault-tolerating mechanisms in e-speak, the Open Source software platform for building e-commerce applications. Among the various issues we discuss are the interceptor programming model as infrastructural enabler of dependability, high-availability features of the e-speak platform itself, and exactly-once semantics and transactional properties for services running on top of e-speak.
