What a beautiful example, I tried each step and Absolutely worked, and created Employee API deployed using API Gateway and Lambda function. Thank you Basant ji :)

[@MuayViaura]

Great lecture! Simple and obious!! Thank you very much!!

[@hunterxdk]

Thanks sir, much needed.❤

But why deploy as .zip file instead of jar?

[@Francisco-co3lb]

Hello. I managed to create a jar file, put it on an S3 Bucket an uploaded to the lambda function with success. However, when I try to call any test i get the error Class not found: com.project.cr01.StreamLambdaHandler. The handler configurations has the full path, as in "com.project.cr01.StreamLambdaHandler::handleRequest". I did not create a zip as I was having a lot of errors with those libs, but the lambda accepts the jar, and I see it has all the needed files (i see them also when i download it from the lambda). Any ideas why it's not finding the StreamLambdaHandler class? Thank you so much

[@Javatechie]

No buddy uploading jar won't work you need to create thin jar using zip and play with it . I am not sure why this restrictions

What if our spring boot application has log4j2 integrated...How do we ensure it is able to log our custom message to the log file??.

[@universal4334]

I'm not sure my question is vaild or not, but the spring boot app should be running in tomcat inorder to accept request right ? Will lambda keep on running ? I know that it only startup when request hit lambda, will tomcat start when it get request or it keep on running ? If yes lambda only run for 15 mins right ?

Yes you can join but I will not suggest you to join now as the course will be completed within next 15 days. So it's good to purchase this with half price I will announce that shortly 😀

This is so well explained! Keep up with the good work

[@faixan13]

another day another unique content :) Please ask everyone to delete the instance of lambda and api gateway in the end :D otherwise on free account also will get charge after consuming enough hours. I have faced this in the past.

[@theshivrajofficial8444]

same here bro...2 years ago i followed his tutorial and forgot to delete the resourse. then i got huge bill with free tire

[@Javatechie]

Yes it's good point somehow I missed to update at end of the video . But I Don't think it will charge more as it's a lambda function and you need to only pay as used .

[@tejach3087]

Can you help me with below question like what are the steps need to be done My use case is for example I have to write cloud watch trigger which triggers the lambda and I want to hit only get API only So I want to hit the get api continuously using lambda and cloudwatch trigger

No idea need to check this buddy

Lambda won't charge more . You will pay only when you used it . Regarding free will check and update

[@hasithawickramanayaka6727]

what if we have multiple services such as course service inside the same spring boot project how can deploy it in to the lambda and what would be best approach ?

[@tusharfasate7388]

Still not clear why we used aws lambda here. What other things it did here which ECS or EKS cannot do?

[@ManishTiwari-or8zt]

Using AWS lamda you dont have to manage the server/machine like EC2, EBS, EKS. Using lamda just you need to give the jar/war files. Even scaling also will be taken care by lamda if more traffic l.

[@hunterxdk]

Bro Lambda can auto scale itself horizontally if there are unprecedented traffic on your requests..... for example. Your application has threshold of 1000 request per second which is hosted on 2 core 2Ghz frequency server with 4GB RAM. Lambda can allocate better resources for the time period in which there are 1000+ requests per second in your case. Then later when the traffic is low then it can deallocate the extra resource in the server... which can save subscription charges in comparison to EC2 instance where you can't have this privilege.

[@reeeeel2858]

Is spring boot still relevant in industry with the arrival of node js support for backend development? Would it be a time waste to learn spring boot ?

Yes why not because both url will.have different root url right?
