 ### Lambda scale up
 
-The scale up lambda is triggered by events on a SQS queue. Events on this queued are delayed, which will will give the workflow some time to start running on available runners. For each event the lambda will check the workflow is still queued and no other limits are reached. In that case the lambda will create a new EC2 instance. The lambda only needs to know which launch template to use and which subnets are available. From the available subnets a random one will be chosen. Once the instance is created the event is assumed as handled, and we assume the workflow wil start at some moment once the created instance is ready.
