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 :)
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.
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 .
Bro you need to explain how lambda works i mean how it handles requests and template, connection between SAM template and API gateway. Code walk through is fine. Lamda use cases are different. ECS with fargate auto scaling is best for backend apis.
This was really helpful. How can we enable lambda function url and use that for invoking these controller apis. I tried your code but it doesnt work with lambda function urls as it cannot be deserialized to SpringbootLambdaContainerHandler
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
Thanks for the wonderful video! I do have a follow up question. I'm using a similar project but connected to database - accordingly I have given configuration details for RDS in the applications.properties file. When I test the API gateway for AWS URL through postman it works fine However, if I want to locally test the code on say localhost:8080 - I edit my application.properties to point to the local database usually localhost:3306 but I'm getting error - connection refused. Why does this happen? Is it due to the Streamhandler class that exists in this project?
Excellent approach, thanks for the video. Basant I have a basic question where exactly fit this solution and where to use the other existing docker-k8 approach?
I have a ELB url which have 3 node of app server in differenr AZ ... How and where we can implement lambda here .. please help .. How can we implement Lambda for ELB ( this ELB redirecting to direct to 3 app server and doing Load balancing )
thanks JT. How do you get to know about the Maven Archetype to use in the first place ? what reference's do you use to learn about this ? great content as ever.
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 ?
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
K8s with Docker will have multiple nodes created I think that itself is enough for scaling up and scaling down right , I am still not convinced with how better this AWS Lambda when compared to Docker with k8s., there might be auto scaling facility available in Docker right ?
It was a nice & informative video, but i wanted to understand why the project was created by Intellij idea and not from spring initialzr. Because i was trying to create from spring initializr and couldn't find spring serverless dependancy
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.
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.
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 ?
@@Javatechiesir they api gateway availability etc will b taken care by AWS ? 2- how we can customize gate way url as per company name 3- any aws course u providing for all this ?
Yes you can specify domain url, you have the option to specify it while creating Gateway. Exactly didn't remember the page but yes we can customize it .

Hi Basant, your expertise and eagerness to teach, and simple approach is really admirable.
Thank you for the wonderful tutorial on AWS lambda. Please create a tutorial on deploying Java app using Aws ECS service.
This is so well explained! Keep up with the good work
Hi Basant. Thank you so much for your wonderful real-time example. Thank you for your valuable time for creating this video.
Doing great job sir keep it up ..ur doing great service giving such a knowledge for free of cost hats for you
Appreciate your efforts Basant. Thank You! God bless you.😊
Exactly what I was looking for. Thank you
Great lecture! Simple and obious!!
Thank you very much!!
Great explanation. Very Thankful to you.
followed same steps as in this video and able to do. Thank you
Great Example. Thank You

Hi Bro,
I didn't get how the state of list is maintained, won't the list data removed after each lambda run? How the data still persist in the list?
Appreciate your efforts. Can you please add security also for the same if possible
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??.
thanks JT. How do you get to know about the Maven Archetype to use in the first place ? what reference's do you use to learn about this ? great content as ever.
Hello buddy. I was searching this deployment in medium and then found this solution so thought to share
Thanks sir, much needed.❤
Great Demo. Thanks! Keep up the good work!. Can you explain how to debug this if we wanted to?
Okay sure
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 ?
Since you haven't used any database, how is the data being persisted, given that Lambda functions are stateless?
How stateless relevant with db?
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

Thank you so much! very nice explanation.
I did this 5 years ago and faced a lot of cold start problems then shifted to node.js at last 😢 is the cold start issue resolved now these days ?
😂
its been reduce by snapstart but still takes seconds. I try Quarkus + graal native compile and it is very fast
Same issue so I moved to Google cloud run. Cold boot issues
Followed each step but getting 502 Gateway Timeout issue. What could the issue can you please help me to resolve
Thanks for good tutorial, a good reference.. can u suggest how can we integrate this above lambda project to aws loadbalancer to access the apis
I will do that

thank u for your guide about AWSLambda and Api gateway.
how to remove this services after use??
Just delete the function

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 ?
Sir, is it necessary to install Maven separately to package the application?
If i want to call this Api from other application,then how i can do it ?
it is really an useful vedio. is there any option to run this app locally before depoly into AWS?
Yes we have some CLI from aws need to explore that and update you 👍
@@Javatechie OR else if any spring boot api created thro Spring initializer can be converted to AWS lambda. Anyhow your work is awesome dude !

What if i have two controller and both of them have multiple get or put requests?
