Infrastructure as code “we are all coders now”

Nick Parlow, Fujitsu Distinguished Engineer, Fujitsu

At its simplest, Infrastructure as Code (IaC) is the separation of configuration from platform, using machine readable files to define your computing environment. Using software development practices this approach produces a repeatable, testable and easily maintained environment that can scale into the thousands of servers. There are, however, major challenges, including what to do with all those SCO boxes. Along the way we may take diversions into DevOps, Containers, serverless computing, dirty servers and what your operations department can learn from livestock farming. With luck, there will be a live demo.

Quantum Communication and Networks

Dr. Joseph Spring, Senior Lecturer, University of Hertfordshire

Recent developments in technology are creating opportunities for the practical application of quantum concepts to networks and distributed systems, which could later contribute to the development of a quantum based internet. Quantum repeaters are currently reported as working over distances in excess of 100km, with quantum dark fibre networks achieving distances of 2000km. Quantum based satellite communication are currently proposed with a view to achieving a global network by 2030. A UK National Quantum Technologies programme has been unveiled with the object of making the UK a world leader in quantum technology development. In this discussion we consider the progress being made in this field, together with a selection of issues relating to quantum communications.

Ada Lovelace Commemorative Lecture: Cloud Computing - Demonstration and Directions

Paul Moggridge and Dr. Na Helian, University of Hertfordshire

Using the Cloud is easy. You may already be using the Cloud without realising it! In this presentation, we will demonstrate a variety of ways you can utilise the Cloud. Cloud services are grouped into three layers, Software, Platform and Infrastructure as a Service - SaaS, PaaS and IaaS. This talk will look at the aims and examples of each specific type, with insights of value for users both new and experienced on the topic including a discussion on the directions that Cloud Computing is moving in. Please note, this presentation will be interactive. Please bring a device capable of browsing the web, a smartphone is ideal.
