i have been working with AWS Glue for 2-3 years , it allows you to locate , move and transform all your data sets across your business , the most interesting thing about AWS Glue is ,it's server less you can run your all ETL jobs by just pointing Glue to them, you don't need to configure , provision or spinup servers , and you don't need to manage their life cycle , it customizes your task by 80-85%!!
it's not that easy to learn and implement AWS Glue because it contains concepts like Crawlers , ETL scripts etc.
one of the reliable and heavily used server less software for performing all kinds of ETL tasks on data sets!!
we're using it for 2-3 years for performing all the ETL tasks on our Structured as well as Semi-Structure data sets!!
