Containers have been one of the most significant technology trends of the last decade. But what are they, and what impact can they have?

Containerisation has been one of the most significant trends in the software industry of the last decade. But what is it, exactly? And how could it benefit your engineers and your organisation as a whole?

In this session you’ll hear from AND Digital’s Jim Walker as he explains containers and the key technologies behind it, including Docker and Kubernetes.


Jim will give an overview of the emergence of containers and Docker, before performing a demo where he will build a container from scratch. He’ll offer a technical perspective on what this means for engineers, before joining the dots to the immense value this way of building software can offer businesses: modularity, flexibility, and speed.


If you’ve ever wondered exactly what all the fuss is about Docker, Kubernetes, and containerisation in general, this is the event for you - not only will you get the big picture, you’ll also see it in action.


This session is part of AND Digital’s and ScotlandIS’ Tech Week. Running from 18th-22nd October, Tech Week will feature Scotland’s best and brightest tech talents, who will showcase our dynamic digital sector and discuss the issues that matter in the industry today.
