AKS host cron jobs

I have to host multiple(approx 8) cron jobs on AKS and schedule it for fixed time.

  • All job will run independently as linux docker container.
  • All jobs are light weight in processing.
  • All jobs will be processing .csv file from storage blob location and updates in Azure Sql database.

Could you please suggest what should be the recommended AKS instance size, node count and other consideration required for scheduling multiple cron jobs on AKS.
(Please note that I have to set up AKS from scratch to host these cron jobs. Besides hosting cron job there is NO other requirement to host api services etc. so AKS will be ONLY used to host cron job as of now.)
