ABSTRACT
Building scalable, highly available publish/subscribe (pub/sub) systems can require sophisticated algorithms and a tremendous amount of engineering effort. This paper demonstrates a way to build a pub/sub broker on top of the OpenWhisk serverless platform that performs topic-based and content-based matching. This approach radically simplifies the design and significantly reduces the amount of code while still achieving scalability targets. Furthermore, we present a publisher/subscriber client application to interact with the broker as well as an evaluator application that enforces heavy workload on the broker to measure the scalability and latency of the pub/sub system and discover the potential bottlenecks.

The serverless paradigm simplifies the development and deployment of highly available applications by delegating most of the operational concerns ...
Toward Efficient Filter Privacy-Aware Content-Based Pub/Sub Systems
In recent years, the content-based publish/subscribe , has become a popular paradigm to decouple information producers and consumers with the help of brokers. Unfortunately, when users register their personal interests to the brokers, the privacy ...
Empirical Evaluation of Content-based Pub/Sub Systems over Cloud Infrastructure
EUC '10: Proceedings of the 2010 IEEE/IFIP International Conference on Embedded and Ubiquitous ComputingPub/Sub systems permit users to submit subscriptions and notify interested users of the events detected in a distributed way. Moving a Pub/Sub system to a cloud infrastructure is for high performance and scalability. This paper describes how to migrate ...
