+1 from me for using a Java based Lambda. I hate all this node.js nonsense

[@saikatdutta4698]

Bro complied language are not great for lambda due cold start.

[@AnandKumar-is1lp]

You rocks, big thanks for your videos

[@lorenzodinelli2329]

Sei un grande, grazie a te AWS smetterà di provare a SPILLARMI gli spiccioli con quelle chiamate

[@ganeshmp3837]

nice video i was looking for something lambda function with java this helped me out

[@RajeshSamson]

Very Nice video and it's an interesting topic to investigate.

[@pranith2047]

Thank you. Well explained

[@sandeepbaniya7666]

Great bro, looking for more tutorials

[@AnkitYadav-pm3xi]

Learned something new.. thanks

[@saleemmaliknagoorgani7200]

Nice tutorial. But you've missed to show the S3 storage and how it's being saved.

[@ajinkyapande9767]

Amazing...

[@karthiky898989]

Excellent video

[@rahulgoti3864]

Thank You

[@shaileshsingh5664]

thanks it was good

[@anirbanroy1524]

Great one.. can you show something with posting some values to api gateway/ lambda.

[@fanaticcoders6847]

Good one.. with lamba 👍

[@jeraldlawrence5605]

Awesome

[@kaushalkishorerocker]

Good job bro , can you please give a demo on how will it work if trigger point is code commit from git . Additionally lambda as of now is not taking any specific object request i.e the request is a generic object how can we make it object eccentric like a student object coming in the request .

[@brijeshshemadkar356]

How can i merge two different log group like want to get data from lamba logs and api gateway logs

It's possible to deploy spring boot app on lambda
I mean what about fronted ?

[@TechPrimers]

Yes you can do it. However startup time of the lambda will be more. The more complexity you add in your lambda it will turn into a bigger chunk and wont be usable with lambda. Since lambda has size n memory restriction. For UI, you can host it as another Lambda with a API Gateway.

[@Kishor.Boddu_25]

can our lambda call mirco service which is running inside the ec2 to get the response back to api gateway?

[@TechPrimers]

yes you can use it like any other service.

[@sanjaykantheti4002]

Ajay, Did the jar uploaded to s3 bucket by default when we uploaded to lambda??

[@TechPrimers]

actually it didn't. But we can references from our S3 buckets

[@susobhandas999]

Sir can you please make a video on how to use aws cognito with aws lamda and gateway

[@sqlearth7045]

Hello Primers,
I have just watched Tech primers AWS lambda tutorial on youtube. I have doubt whihc is mentioned below
1. If we want to expose 50 on aws lambda, then is we need to create 50 lambda function with 50 java projects.
Please do answer me it's important to know.

[@marinecommando2]

How you read all these technologies so fast. R u referring other TH-cam videos or read documentation n implement?

[@JaNaMSoNi]

Doc's I think

[@TechPrimers]

Mixture of both. But most of the time i make videos on topic that lack good implementation detail. So i try out myself by using the docs. For AWS lambda it took more than a week since the docs are stale and no one showed using java.

[@ashishkapoor6999]

Nice Video. I just wants to know how can I debug my lambda project code?. As we don't have main method how can I check my code is fine?

[@TechPrimers]

You can use SAM to run lambda locally

[@rameshn6721]

Great video. I ran by the same steps, but finally didn't work with awsgateway url. Getting 500 error

[@tracy_gao]

The BGM makes me be extracted.

[@shekarbk1274]

Nicely explained but you missed mentioning how you will trigger S3 and store the jar in S3

[@TechPrimers]

That's where the CICD comes into picture

[@shekarbk1274]

@@TechPrimers Thank you, can I create cookie inside lambda function?

[@vijyr4515]

Hello techprimers where you have used s3...?? U did not uploaded the jar/war file to s3 if am wrong...?

[@TechPrimers]

hi vijy, the uploaded jar resides in s3, that is where Lambda gets the artifact from. though we say serverless, we need a server and storage space to store the jar.

[@vijyr4515]

@@TechPrimers Thank for your reply

[@karthikgayakwad6289]

Where exactly in s3 does it store??

How to deploy springboot application with 5 or 6 rest api ?

[@TechPrimers]

You should not deploy spring boot to lambda. Instead split it into 5/6 lambda’s and use API Gateway to trigger them if you need serverless processing.

[@MrPavanmallela]

But you missed to show the S3 bucket where code is placed.

[@MrPavanmallela]

can you give a link where this CICD is shown to push the code from git and linked to S3 ?
