Addressing the transaction challenge in a cloud-native world

This session enables developers to question the validity of the assumption that cloud-native microservices must be stateless in order to function effectively on the cloud. In this session we dive into why stateful microservices are still necessary in the cloud, why more traditional methods of implementing transactions may not be effective for the cloud and the alternative offered by MicroProfile LRA (Long Running Actions). We'll dive deeper into this specification and how it can be implemented within an application.

Attendees will gain an understanding of MicroProfile LRA and hopefully begin to question the assumption of stateless microservices.

No specific knowledge required for this session, but a basic understanding of Java and application architecture is helpful.

Objective of the presentation:

With microservices comes great benefits but also great challenges! One such challenge is data consistency and integrity. Traditionally, tightly coupled transactions were used to ensure strong consistency and isolation. However, this results in strong coupling between services due to data locking and decreasing concurrency, both of which are unsuitable for microservices. So, how do we provide consistency guarantees for flows that span long periods of time in cloud-native applications? We'll address this challenge by investigating the Saga pattern for distributed transactions, the MicroProfile Long Running Action (LRA) specification and how these can be used to develop effective cloud-native Java microservices.
