Huge thanks for this amazing video! Being proficient in Java, I had been looking for a cdk java project that would deploy the resources coded in Java. This helped a lot.

This is a golden video. I can imaging how much work you done to present in a simple manner. Much appreciated Ajay

Cool very crisp and clear steps....I should have watched this before trying myself from scratch.... and I missed the shade plugging and got classnot found ... and the maven multi module steps also very thanks for the nice video mate 🙂

Very detailed and easy to follow. Thanks for putting this together.

I really appreciate a lott for your efforts Ajay for finding the best solution to pack all java dependencies from pom.xml into one single folder and using them into the CDK folder where the actual code is kept. Hatts off for making coding so simpler using modular approach 💯💯❤❤👍👍

Thanku buddy. Such an awesome and easy to follow tut. <3
Can you also make video on how to read from S3 using Lambda in JAVA using CDK. That would be helpful

[JeevanSunkersett]

Great explanation. Thank you. So is true that cdk init with language=java, does not create a sub java-maven-module, which can then be used to build only the jar artifact and used later in the cdk created infra module. and the manual steps that you explained will have to be done everytime?

Thanks for making such an informative video.

I am just learning the things. Where should we specify our aws accountid and region in this example ?

[varshinikaithapuram]

How do we connect our AWS account to the code, so as to see the changes in our AWS Management Console. Can you please specify this?

Unfortunately my IDEA version does not have the Maven archetype you are using to create the "functions" module. Do you have a GitHub repo with the code in?

[satishmutyala]

Hi Ajay,
I strongly believe you should be best person to give me some advise.
I have created an api using Java and infra code using typescript and everything is sorted out.
With the performance, how can I reduce the cold start time of lambda, currently it is taking 8-10 secs to warm up lambda function.
Please advise how you resolved this issue . Thank you

Bro, this is awesome. Can you please add this working project in github?

Do you know if there is a way to configure your AWS lambda account, to tell Amazon a max dollar amount you want to spend, and then if you accidentally exceed that amount with your resources, they either immediately notify you, or just simply shut down your site? I'd prefer it works that way.

I'd hate to get a big surprise bill from amazon, because I didn't know my code was very inefficient, and the code was spending too much time during a function invocation.

Hi, Ajay it's just a humble request that can you make a video tutorial of Testing lambda functions using Selenium code with java in Amazon linux 2 environment ?
As it would help me a lot, bcz i am stuck while testing the lambda function on AWS management console.. !!! 🙏🙏
