Another mini-vacation so another few hours to sit and write down some things that have been rumbling around in my head for a while. This time it's about Docker (container) images, microservices and how they can be combined to provide a natural unit of failure when building multi-service applications or composite services. Check it out on my personal blog, but hopefully the conclusion should be obvious:

"If you are building multiple microservices, or using them from other groups and organisations, within your applications or composite service(s), then do some thinking about how they are related and if they should fail as a unit then pull them together into a single image."
