Have you run into issues with Lambda with complex tasks? I thought there was a 15 minute limit to tasks, plus a maximum storage size when importing large dependencies, etc?
The latex example did not run entirely on Lambda. Lambda would write a job into a queue (just Postgres), trigger a launch of a beefy ec2 instance, after which a worker on that ec2 picked up the job. Another lambda function would be called by the server itself to shut down the worker when all jobs were done.
Kludgy and slow. But it worked and did save some money, because the instance running this latex worker was big and chunky yet utilized maybe 10 hours a month.
Lambda was mostly acting as a kldugy load-balancer really.
