I went along to Serverlessconf last week and wrote up a couple of InfoQ news pieces about it: Day 1 – Serverless Operations is Not a Solved Problem The emergent theme from day one of the Serverlessconf London 2016 was that far from being ‘NoOps’, Serverless platforms bring with them substantial operational challenges. The physical servers […]

Rising from the ashes of GigaOm the tribal gathering of cloud elders that is Structure has returned, and got off to a strong start with Battery Venture’s Adrian Cockcroft presenting on the State of the Cloud and Container Ecosystems. Cockcroft paid particular attention to the impact of containers, which wasn’t even a major discussion topic at […]
