Thanks, It's well explained. Please continue the good work and keep sharing.

Simply Amazing Teacher.

[@mohitmansi11]

Good demo video . Explanation of each and every step is spot on .

[@listentolearn2363]

Thank you :)

[@chiranjeevikatta8116]

Explained well 👏👏, can we have Infrastructure As Code via AWS SAM or Terraform

[@kapilchhipa2143]

do we get logs of sqs and sns as well? what if we dont see any logs in lambda. how do we debug ? should we see logs of sns then sqs?

[@vikasbhardwaj8989]

Thank you for explaining it very well.

[@listentolearn2363]

You are welcome! :)

[@vasugoriya1452]

Why we need to create sns and sqs instead of we can directly invoke lambda from s3

[@basavarajpn4801]

If there are 1000files loaded Into s3bucket lambda can handle only 1000functions in concurrent run at a time ,so if in case there is SQS,sqs holds the messages from s3 events and queues it and passes to lambda to process all files with out any issues

[@listentolearn2363]

Hello, thanks for you interest.. SNS SQS pattern will help in parallel processing by distributing the messages to various queues based on several attributes.

[@CHiRaStar1]

Exceptional. Very insightful. Is there any possibility of connecting with you discuss about work

[@listentolearn2363]

thanks :) I can reply here..

[@Ksr3740]

Hi there, i have actually run into a problem. when i try to add the lambda trigger into sqs it throws an error message "Error code: InvalidParameterValueException. Error message: The provided execution role does not have permissions to call DeleteMessage on SQS" and i have used the same policy for the sqs as shown in this video. any idea how to solve this?

[@souravsinha5330]

Well explained mam, learning from ur vast experience.

[@maciekpaciarski9343]

where exactly did you get the added policy from github for Lambda ?From creator of policy ?

[@muqtadirahmd]

Hi, great video and thanks for uploading. I have a question. When would I want to add a SNS and SQS service in my architecture when I know I can trigger a Lambda directly from S3? Can you please tell the use cases when it would be helpful to do so. Thanks in advance!

[@listentolearn2363]

Thanks Muqtadirahmd! SNS SQS pattern will help in parallel processing by distributing the messages to various queues based on several attributes.

[@HemaSri-e5n]

Can we create sns topic without changing access policy to advanced

[@yaminisingh7271]

HI, demn girl you explained it so well. I have a question, if we follow the exact pipeline and in the lambda function write a code to connect to ec2 instance and over that ec2 use the newly added file in s3 bucket input for a python code for some calculation. It should work fine right. For ex : - upload the file in s3 -> sns topic-> sqs que -> lambda -> ec2 (run and connect) -> runs the python file.(command given in lambda function). correct?

[@ThangTran-hi3es]

Thank you, great content 🎉

[@nikitanagarkar1643]

Hi , will this work for prefixes within s3 bucket?

[@JosephOfobuike]

Hi there. This is a very straight forward easy to understand tutorial. Do tell, did the SQS policy change? The policy you posted on Github is different from what I on your screen.

[@listentolearn2363]

Thanks :) please use the policy in GitHub. Thanks

[@surajgusain3656]

just the perfect and the crisp one....thnks...

[@pranavswaroop5232]

Thank you so much!

[@bhumikalalchandani321]

Coudnt get how file 2 on reiploaded went to queue2 ....anyone😢...ie by default file queue 1 file2 queuue 2 so onn...

[@listentolearn2363]

Hi, It is because of the Subscription filter policy set in the SNS while adding the queue to it. Pleas see from 14:45 in the video.

[@denisafonkin8795]

what is the "arn:aws:sqs:::q1" ?

[@listentolearn2363]

that is the arn of the queue. please replace and with actual values

[@raqueseharris]

if you run into the problem of "Error code: InvalidParameterValueException. Error message: The provided execution role does not have permissions to call DeleteMessage on SQS" Follow these instructions: Go to IAM in the AWS Console Click on roles Select your Lambda function execution role or create one if you don't already have Add the AWS managed LambdaSQSQueueExecutionRole policy to the role. The policy contains all the permissions to call the required actions on SQS from Lambda. The ARN of the policy is arn:aws:iam::aws:policy/service-role/AWSLambdaSQSQueueExecutionRole. Save the role, and then try again to add the trigger. This time it will work fine.

Make video in hindi mam

[@listentolearn2363]

Sorry, I might continue with English for a while.

[@avpruggedboys1005]

Hi mam

[@avpruggedboys1005]

One doubt mam

[@ĐạtNguyễn-o2e2h]

10:22 you should edit "arn:aws:sqs:us-east-1: 609292000349:q1" -> "arn:aws:sqs:us-east-1: 609292000349:queue1"
