QCon London 2027

QCon London is InfoQ's long-running practitioner conference for senior engineers, architects and engineering leaders, now in its third decade. It is not a DevOps-only conference, but operations work runs through the programme: the 2027 line-up includes an Observability & SRE stream (debugging distributed systems, connecting systems through APIs and telemetry), cloud and platform-engineering tracks, and a day on architecting for resilience, risk and governance, alongside heavy AI-in-production content. Fifteen editorial tracks run across three days at the QEII Centre opposite Westminster Abbey, each built from five talks chosen by a track host from the programme committee, and most tracks add a facilitated unconference session. There is no open call for papers; speakers are invited. Vendor content is kept to separately labelled sponsored tracks. The 2027 conference runs 13 to 15 April, with an optional certification workshop on the 16th. Early-bird pricing of GBP 2,390 before VAT lasts until 10 November 2026 and rises in steps after that. In-person passes include breakfast, lunch and twelve months of access to most session recordings, and many talks later appear free with transcripts on InfoQ. Worth it for teams that want production war stories from large organisations and can justify the ticket.
