Moving from Transactions to Streams to Gain Consistency

by Jan Stenberg on  Mar 13, 2016

With many databases in a system they are rarely independent from each other, instead pieces of the same data are stored in many of them.

Working with a stream of changes in the order they are created is a much simpler and more resilient solution, Martin Kleppmann stated in his presentation at the recent QCon London conference.

Don’t Think like an Engineer When Designing Microservices

by Jan Stenberg on  Feb 29, 2016 1

When designing microservices and their APIs, you need to think like a designer focusing on the users, Nic Benders claimed in his presentation at the recent Microservices Practitioner Summit. Design the API first, then build your services with an outside-in approach.
