Excelent video. Thank you very much. For those who use free tier, some tips for no cost. 1 - for ddbb (DatabaseStack), change machine and use: InstanceClass.T4G, InstanceSize.MICRO 2 - dont use NAT gateway (NetworkingStack) 3 - Dont use awsSecret. Instead, use user/password directly (only for testing purpose)
I really appreciate the comment, and I've updated the GitHub repo to have the first 2. My preference is to keep the secret in place, purely to demonstrate the best practices. But The DB and Nat Gateways are done :)
great video thanks, just so I understand, when the lambda is invoked is it starting up the spring boot application every time? seems like that would be pretty slow, so I hope not.
Thanks! Whenever a new Lambda execution environment is created then yes Sprint Boot needs to startup up every time. I have another video in the same playlist on Lambda SnapStart which prevents this though, its well worth checking that out as well 😀
Good video but I feel it lacks few explanations, for example, all pom.xml dependencies used, postgres configuration and its integration with lambda etc.
Im assuming you have lamba apigw proxy set up which requires very particular set up as response like status code, body, 64endcoding. Do you have send it back as httprespond type from springboot?
There's no manual configuration of the API Gateway. AWS SAM configures all of the API Gateway resources and then the serverless Java container manages the translation from API GW to Spring and back again
Hi James! I've really appreciated your videos for learning about AWS Lambda. I've got an application on SpringBoot 3 that follows the aws-serverless-container, but for whatever reason the Lambda function keeps returning blank response body and headers. When I set it up to run locally (without AWS Lambda function), everything works perfectly. Could you please help me troubleshoot?
Excellent vid. 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.
You can set budgets on your account so that you get notified when your spend goes over a certain level. Link below. You can also use things like reserved concurrency in Lambda to control the scaling behaviours. If this is a personal AWS account you're using for learning you can also delete all of your infrastructure when you're not using it. Serverless resources are quick to spin up and tear down, so deleting them when you're not using them removes the risk completely. aws.amazon.com/aws-cost-management/aws-budgets/
@@serverlessjames waist of time for beginners. You didn't explain about some configuration like sam file some dependency and all. How can a beginner figure it out what happened in background. And how dependency is relevant to which part. And please this is only feedback not a hate about you.

Thank you for wrapping up everything in such a short time and just show what is needed! Awesome!! 🙂
thanks for keeping it simple!
how to use Springboot features like Spring JPA rathar than Spring rest controller for say S3Events. I'm not able to combain these.

whats spins up springboot app ? is it main method of @Springbboot app or the one inside handler?
Wonderful video. Would you mind to explain how we can deploy it as native with GraalVM, PLEASE? 🥺
Hey Mikhail, I certainly will look at doing that in the future. Thanks for reaching out 🎉☺️
Thanks!
Can CodePipeline, Codecommit auto deploy(CICD) springboot to AWS Lambda ?
Yes, absolutely!
@@serverlessjames Thank you, can you add a new video for that part?
pleaase do more videos about spring boot serverless architecture,dto to entity mapping etc ..thank youuuuuu
Good video but I feel it lacks few explanations, for example, all pom.xml dependencies used, postgres configuration and its integration with lambda etc.
Great feedback, thanks. I try to keep my videos short and to the point, but these would have been good additions.

Please be care with sources for this video. It set up with xlarge2 database, which consumed from me $200 in several days without any usage!
Sorry to hear that, and thanks for pointing it out, I'll update the source code.
@@serverlessjames also $30 for NAT Gateway (VPC as I understood)
@Likrant Good to know. What a kind of DB it was? I plan to use DynamoDB which is free up to 25 GB so I hope that I will avoid such problems
Could you please give a way to deploy it through aws console as my organisation hasn't given me permission to use sam.
Is there another tool you are allowed to use? Terraform, CDK etc?
@@serverlessjames yes we are allowed to use terraform...but we can't use SAM.
pls provide some solution..
Awesome, great video.
