But what if I use one lambda per account?<BR />And there is also S3 with lambda. And there is one more method to use AWS SAM.<BR />I'm confused which one to choose(I dont want to use kinesis). How do I choose and on what basis can I choose an option?<BR />And I want to automate subscribing and want sourcetype per service</P> Tue, 13 Jan 2026 01:40:18 GMT richah 2026-01-13T01:40:18Z https://community.splunk.com/t5/Getting-Data-In/How-to-use-Lambda-to-push-logs-to-Splunk-Cloud/m-p/757206#M120113 <P>I'm trying to onboard data from AWS to Splunk Cloud and planning to use Lambda But we have numerous options within Lambda.
