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.
My goodness buddy 😊
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
just started watching your AWS series, concise and clear, thank you. By the way I also learnt a lot from your other topics too. keep the good work going.
Thank you sir for uploading lecture on Aws Lambda
Nice explanation. Thank you for sharing such a valuable information.
thanks lord for share your knowledge
Good explanation and more informative
you are the super teacher...
Sir , thanks for your videos and support
God bless you!!
Great video, hands on coding with demo .
Excellent video
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!
Hi Sir, You are doing a awesome job. If possible please add how to use VPC with subnet and internet gateway and route table .
Very nice.
Thank you so much for useful video
Glad it was helpful!
Excellent 🔥
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
Thanks 🎉🎉🎉
Ultimate
Hi Basant , in continuation to this series, please add trigger and integration with API gateway topics as well.
Yup it's my upcoming tutorial
Adde please check
Please share some video content where microservices orchestration using AWS step functions. Thanks.
Let's suppose we need to build 5 Handlers (Employee Handler, Department Handler, etc.) then, is we have to create 5 different projects having spring cloud function and lambda functions as well? Please answer.
Awesome video, thank you so much, I spent several nights looking for how to do this! Please, if want to expose these two methods on Lambda, do we have to deploy 2 different lambda, each with it's method in the Environment FUNCTION_NAME value?
Even I have the same question
Yes you need to deploy separate method by mention function name
@@Javatechie is it like every time we need to upload the jar for a new function
Hi,
Thanks for this topic but could you explain how to cosume JSON request please?
Thanks for such a lovely video!
Just one question:
in the latest version in 2024 has SpringBootRequestHandler been replaced by
org.springframework.cloud.function.adapter.aws.FunctionInvoker ?
Can we use filter with spring code as authorisation API gateway authorizer . I want to write code in sping boot and used lamda once token is available .and then will create Auth permission to give roles
Hi I tried with a string reversal one which is working fine... If I want to send two int as input and find out the sum facing issue like LinkedHashMap cannot cast to class entity.MyData. pls help me out to find the sum of two numbers with AWS lambda
That was very helpful .. just to confirm one thing .. here the RequestHandler has fixed types(String and List) since the functions are using so .. if i use another function in the same applicatio which returns a String or Number , do i have to create anothere RequestHandler specifying the new type.
Then make your handler generic rather than specify data type we can add object as request and response
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?
1. if you are using free tire and if you will exceed the threshold limit then you need to pay
2. We can't directly test it through postman but you an integrate API gateway and then access it from postman
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! I hope you do a follow up connecting a database (NoSQL or SQL) and authentication. Is it DynomoDB that's usually used?
Very usefull content!! Could you continue this video by showing how to call this function by api gateway?
Yes already uploaded how to call function using API gateway trigger
@@Javatechie Can you share a link on how to upload Spring boot 2 API's in AWS LAMBDA?
Yes am using spring boot 2.3.x version please cross verify once
@@Javatechie I really apreciate you hard working. But, where is the step by step on how to setup ApiGateway calling a lamda function?
@@Javatechie Does this functions supports SpringBootApiGatewayRequestHandler? I am trying to get request parameters and restApiBody .
SpringBootRequestHandler is Deprecated now. which one is alternative to use?
Bro is it sufficient for interviews if we follow your AWS tutorial.
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.
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
Have a doubt .
Spring Cloud Functions accepts only Supplier , Function and Consumer as endpoints. These interfaces do not have any support for exception handling like throwing exceptions back to user. How would you handle it.
Hi Shahul , nice one i didn't notice this. will update you
Valuing these revelations? There's a book I'd spotlight that delves just as deep. "AWS Unleashed: Mastering Amazon Web Services for Software Engineers" by Harrison Quill
Hello techie gi
Server is closing automatically when I am running spring cloud function local , doing simple start from IDE
Nice tutorial. Do you know how we can integrate it with AWS Fargate for task executions?
Hi it's already there please checkout my AWS playlist
Can you provide video on light weight jar deploy on lambda
JT... was does JAR size need to be reduced ? tks
Iam getting class not found exception in AWS lamda once runs the test button
While creating spring boot micro service architecture do we need to create different project or in single project all this services we can create? I mean product catalog is one service does it mean it is created as different starter project?
Yes each service means different project
How to handle the function if I have Map or list as a input?
ending up class not found exception with OrderHandler. Can you please help
Please build jar properly and deploy the jar which end with -aws
Why we are using curl only? Can't we use postman?
Nice video..how can we have more than one function here ?
after integrating this lambda function with api i am facing this error {"message": "Internal server error"}
Thanks a lot for content. one question How can we achieve same thing using terraform if you can make video or share script for the same
I am not aware about this terafom but I will check and update
@@Javatechie thanks..and can you share light weight jar solution as well
Can we add more (key,value)s in Configuration so that everytime I no need to change the configuration value with my java class function name ?
Yes you can
Can we have a function to take some payload just like a POST endpoint in REST ?
For that you need to use spring cloud function concept with Function interface (java 8)
Hi Techies, if I have a spring-boot Scheduler project how can I deploy it on lambada (Example: I have below method which runs for every 5 sec how can I run this.? @Scheduled(fixedRate = 5000)
public void printDate() {
System.out.println("============Current Date is============"+ dateFormat.format(new Date()));
})
Any Suggestions Appreciated.
Hi, thank you for the video...
can we also deploy an enitre appliction with spring boot as back end and Angular as front end in the same jar file? if so can you do a small app?
Thank you!!
Okay I will do that
Java Techie great, thank you!!!!
If this theme resonates with you, there's a book that'll likely echo in the same way. "AWS Unleashed: Mastering Amazon Web Services for Software Engineers" by Harrison Quill
Please make a video to retrieve data from mysql database using aws lambda in java.
Hi Sir amazing content and very good explanation.
Sir, I am trying to run an OCR(in my case Tesseract). I am taking a png file from my S3 bucket. But I am not getting how to give that input to the OCR which in turn is running on AWS lambda. Please can you help?
Is there any email which I can show you my progress?
Thanks in advance.
Please connect javatechie4u@gmail.com
Can we use bufferedInputStream to read file from S3 in lambda function?
Not tried buddy
Other than curl how will you test this?
Why on AWS you reused that environment you used just one function name?
Can't you add one more for other method?
Please check my AWS lambda and API gateway integration video I added more method
Can you please do one tutorial with integrating with the database?
It's already there please check with RDS and dynamodb
Db connection examples also pls upload
It's already there please checkout my AWS playlist
@@Javatechie pls provide the youtube link anna

I am trying out the example in this video. SpringBootRequestHandler is deprecated. What should I do with OrderHandler class?
Instead of using OrderHandler class, I used org.springframework.cloud.function.adapter.aws.FunctionInvoker class. It works.
@18.00 how to call from postman any idea?
Can you do video on spring boot rest API application with AWS lambda (deploy). please
Sir...if possible pls provide with document also...becz some statments and annotations are not understanding getting adouts...sir plzzz..

@JavaTechie Lambda internally run on EC2 or containers?
Ec2 only
Can we have multiple Funtion_Name in AWS lambda function for single project?
Yes you can
Sir can you help me that docker image is OS dependent or not
No it's not
How we can integrate swagger with lambda service? can you share any sample
I never tried let me check
Hi, may I know which screen recorder you are using to record videos?
Screenpresso
@@Javatechie thanks
any EKS video you have?
I didn't tried it yet .
Great, we can test this from postman as well
I have 2 queries.
1. Can we deploy 2 services and communicate each other using resttemplate or any other?
2. Can you make a spring boot crud app and do in aws lambda?
Will do 🙂
please upload lambda jwt auth in gateway request without Cognito
Thanks! but when i trie to run the application it's not bringing up the embedded tomcat. Am i missing something here?
Any error or consol log
@@Javatechie no error just the main method runs and completes without the tomcat not loaded!
@@jayakanthan.durairaj server not required here
Please try to understand what I explained about serverless , just expose your api as function without connect with any serve (tomcat)
@@Javatechie for me also when i tried to run the application it's not bringing up the embedded tomcat. no error just the main method runs and completes without the tomcat not loaded!. since application is not ruuning so it can't expose any api
after adding- spring-cloud-starter-function-web, it working
Hi sir
How we will maintain version ing
Which versioning you are asking ? Am not getting it
Spring context takes a very long time to load.
how execute POST request using lambda?
Use Function for post method
@@Javatechie ok, thanks, but how to execute POST request during executing lambda from UI
In lambda console you need to pass payload .
@@Javatechie ok thanks
also question regarding OrderHandler, why do you not using StreamLambdaHandler?
github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot
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.
Can you please add this code git and share the url
Git link mentioned in video description
Will this run in local?? I've downloaded from git but app is terminated and spring boot does not work. :(
Yes we can run in local
@@Javatechie I am not able to run in my local machine. What's the fix?
What error are you getting
