Special Report: Attendee Key Takeaways from QCon London 2020

QCon London Key Takeaways [header]( [QCon returned to London]( this past March for its fourteenth year in the city, attracting over 1,600 senior developers, architects, data engineers, team leads, and CTOs. The conference opened with [Alasdair Allan](, setting the scene with "The Internet of Things Might Have Less Internet Than We Thought." Allan highlighted areas where software adds value to our daily lives — everything from smart light bulbs to virtual assistants. However, he also outlined the challenges and negative failure modes and provided motivation for writing effective (and secure) software for IoT products, edge devices, and consumer goods. Our day two keynote from [Anjuan Simmons]( focused on "Technical Leadership through the Underground Railroad." Simmons used a historical lens to look at the importance of leaders and their associated skills when working within software projects. Sharing the technical vision, working to be constantly prepared, and being bold with your actions are all vitally important regardless of what type of software is being delivered. The third day of QCon London contained two keynotes. The morning keynote was presented by [Katie Gamanji](, and discussed the "Interoperability of Open-Source Tools: The Emergence of Interfaces." Gamanji provided insight into the current cloud technology landscape and explored the evolution of related interfaces that is being driven by the Kubernetes and Cloud Native Computing Foundation (CNCF) communities. In the evening, QCon London closed with a superb keynote from [Prof Richard Wiseman](, where he presented "The Apollo Mindset: Making Mission Impossible, Possible." Wiseman provided a historical overview of NASA’s Apollo project and argued that we should all aim for the stars. He stated that seemingly impossible goals can be achieved if we approach them "one step at a time." Over the initial three days of the conference, the major trends in modern software development were well represented across the 18 individually curated tracks. The QCon London 2020 tracks featured deeply technical topics such as next-generation microservices, streaming data pipelines, cloud and Kubernetes, machine learning/AI, developer experience, architecture, modern language innovation, and more. In addition to featuring technical leaders and software engineering practitioners from popular technology organizations, like Docker, Deliveroo, Monzo, IBM, BBC, and the FT, the conference included other practitioners from the resilience engineering and psychology fields. Dr. Laura Maguire provided a fascinating insight into the costs of coordination during outages and production incidents. Andrea Dobson-Kock discussed balancing risk and psychological safety, and how to use insight from this field to build learning organizations. In total, the conference featured [174 speakers]((a 9-1 attendee to speaker ratio) over the three days of the conference. Workshop sessions on days 4 and 5 included a remote meeting masterclass, introduction to AI/ML for software engineers, tech lead skills for developers, and courses on designing, building, and debugging microservices. Several additional workshops provided a deep-dive into specific technologies, such as Terraform, Istio, Docker, Kubernetes, Apache Kafka, and Java. InfoQ had a number of editors at the event, and you can read the [QCon London news coverage online](. We’ve already started making the [videos and complete transcripts]( from the event, available online.
