As system designers move their code to cloud and microservice architectures, some opinions suggested distributed transactions were not appropriate for use in those environments and should be avoided - transaction models employing locking were cited as having an unacceptable impact on the scalability of the application.

Using practical examples, we will show how a technique known as Long Running Actions allows applications to achieve atomic outcomes whilst reducing the duration that locks are held on the data used by the application thereby facilitating greater scalability.

A description of the principles used for this work is available at
