The article says the test involved 1000 nodes running 50 containers each, but the conclusion only talks about "no difference between 1st and 30000th container". So we can assume things between 30k and 50k containers didn't go as smoothly? Or did I miss something?

Possibly a copy error? The article says 30 containers on each node in the specs but 50 in the text.

It's a copy error. Initially we tested 30k containers, then later expanded the test to 50k. In both cases Swarm keeps scheduling without breaking a sweat.

Do understand that your target with this setup was to load test the Swarm manager and 30K is quite impressive.

Did you do / are you planning to do a test with other than the low end T2.micros to see how much of the API latency might be related to the type of nodes used.

In other words - if my intention would be to minimise the API latency - how would you approach this.

Planning to run a Swarm test (with a few 100 nodes) on Digital Ocean where we have 2 nics per machine - by this we can test latency / response time of the containers to their external work load plus to the API / Swarm manager on separate networks & nics.
