i written a function in aws lambda for html to pdf conversion using nodejs chrome-aws-lambda puppeteer library. but i need to scale this conversion to 10k+ request at a time for user to download the pdf. currently in the website we receive the monthly 10 million request for downloading the pre-generated pdf content but we developed a drag and drop DIY(Do it yourself) tool which user can download the page which after they created.
i tested previously with ec2 machine which can't handle even 40+ request connections of html to pdf.
