How many containers at Alibaba Cloud?
They're using 300,000 containers. The amount of merchandising they do on Singles' Day is around $12 billion. It's stunning. They handle 175,000 transactions per second, and it's all happening through Docker.
I don't think most customers will ever need anything at that scale, but if Docker can handle that scale, that's good.
[Editor's note: A technical presentation later at DockerCon revealed more Singles' Day data from Alibaba Cloud. The largest Docker Swarm cluster on Singles Day was 30,000 nodes, and the company's global image distribution supported 7,000 concurrent Docker pulls. A "pull" fetches and unpacks a container image in just one step.]
