Aws Lambda Function -Practical
The AWS lambda function is a serverless, event-driven compute service that lets your code run manually without managing servers .AWS lambda function use cases include: file processing,IOT backends , mobile applications, web applications, and real-time streaming .
Simply write the code and upload it as a.zip file or load it into an s3 bucket. Lambda executes code on a high-availability compute infrastructure and manages all of the administration of the compute resources. As a result, it’s hassle-free to spin up the sources, scale them, and clean them up after the job is complete.
Here I will show you how you can create a lambda function on your own.

Step 4 :- To run this code we also require pip install requests for that we have add that pip install requests on layers of lambda function . For that we have to zip our packages.
Go to your local terminal. write these commands
Step 1 :- mkdir -p layer/python/lib/python3.9/site-pckages
Step 2 : pip install requests -t layer/python/lib/python3.9/site-pckages
Step 3 : cd layer
Step 4 :- zip -r mypackages.zip *
Step 5 :- After Completing Step 4 click on Layers.Create Layer
Step 6:- After click on add layer. Add your layer.
Step 7 :- Click on Test (You will get your output).
