Thanks a lot! It´s a valueable knowledge to the ones (like me) that are beggining into Lambda!

Once again fantastic tutorial. I have never used Cloud Functions before so it might take time to wrap my head around it but this is giving me a good idea. Thanks

Thanks for this topic. I have learnt some of the concepts from your video demos. Please continue this series with more topics on AWS + Springboot. Also can you please give one example on Scaling with Lambda usage

Basant sir you no need to ask thanks for watching, we would like to thank you always to provide such complex technologies in simplified way. thanks a lot.

Thank you for this great example from you. Would you mind if you can also create an example of a step function which invoke this function and other AWS service in sequence? Thanks again in advance!

Very nice.

Hi Sir, You are doing a awesome job. If possible please add how to use VPC with subnet and internet gateway and route table .

Hey Basant, once again a greate topic and very well explained, few points if you could amplify on - can you demo the client side calling or invoking of such severless function , does it need any AWS configs (IAM role etc) - what the design trade off one lambda function for all end points, or seperate for each end point ~ty

Thank you so much for useful video

Hi @Basant/#javatechie, Here while testing the 2nd function in lambda, you replaced the first function name with 2nd function name and also the parameter required for that function. My question, is there any way to test both the functions sequentially without manually replacing function name? Please do suggest.

Please share some video content where microservices orchestration using AWS step functions. Thanks.

12 sec for first execution is a bad response time. Ideal response time for rest api is below 2 sec.. So is this lambda function can be feasible for UI app?

thanks for the tutorial, I have two questions: I have created a lambda function and I have launched tests, will they charge me something? how can you invoke the lambda function from outside the aws consla, for example from postman?

Hey bro im trying to connect a lambda to a rds database using JPA, but im struggling so much because the Repositories are Null when I @Autowired them to my lambdahandler class, and I cant really find a tutorial that shows how to do it as simple as JDBC tutorials, I dont think that it is 100% neccesary to use annotation @SpringBootApplication, but idk, would appreciate if you have any tutorial of that or you can make it sometime it would be nice, cause every tutorial around shows JDBC, but JPA would be nice too

Will do 🙂

Spring context takes a very long time to load.

You got it completely wrong with AWS lamba and spring boot. You use AWS correto jvm with plain java or micronaut. When using lambda static or beans is not a good idea. On every request a new lambda is churned out. Use SAM template to package and deploy.
