Keynote Details

Research Keynote by Cesare Pautasso (USI): Microservices: An Eventually Inconsistent Architectural Style?

Microservices by definition let each service independently manage its own database. In this talk we illustrate the ultimate consequences of the Polyglot persistence principle, which can be summarized using the BAC theorem: When Backing up a microservice architecture, it is not possible to have both Consistency (after recovery) and full Availability (while backing up the system). In other words, loosely coupled Microservice architectures are doomed to become inconsistent after disaster strikes. We will present and compare several coping strategies to deal with this limitation and discuss how they impact the monolith decomposition process and the corresponding service API boundary design.

Industry Keynote by Christian Fauré (Partner & Scientific Director at OCTO Technology): How to live with the schizophrenia of REST style architecture in the industry?

As a scientific director in a consulting and engineering company, I’m constantly under contradictory injunctions, especially when I have deal with REST Web APIs. I say to my clients “Do not version REST APIs”, but the very next day I say “Ok, I’m going to show you how to version your APIs”. Many other examples will be given during this keynote. How far are the web APIs implemented in the industry from the scientific recommendations (Hint: very far)? Most importantly, how are we to reconcile the scientific point of view with the day to day engineering work of designing and building web APIs? I will refer to the publication of Cyclopædia in London (1728) and the french Encyclopedia from d’Alembert (1751) to explain the way I try to manage my schizophrenia between science and engineering, and between research and industry.

Registration

There is no separate registration for workshops, all registration matters and workshop access is handled by The Web Conference 2018 (WWW2018). Please refer to the WWW 2018 registration page for details and pricing (WWW2018 has numerous workshops and workshop registrations can combine any of those).
