I use lambda to process user input and convert to SQL query for getting from database, instead of having a dedicated server for handling all these DB transactions, saved us lots of money
Thanks for watching our video and sharing your thoughts. Do subscribe to our channel and stay tuned for more. Cheers!
very nice material..but you missed few steps like configuring s3 trigger (which is already created). Please do all steps in the tutorial video freshly so that you won't miss any steps..and it helps us to follow properly. Thanks again for wonderful tutorial.
Hey Subrahmanyam, we are glad that you liked our tutorial. We will definitely look into your suggestions. Do subscribe and stay tuned for updates on our channel. Cheers :)
Hello! I just did this and figured out the final step to create the trigger. In that same Lambda screen, click on the far left box underneath the lambda function called "create trigger". In the far left scroll bar select "S3", then select "Put". Save the function, and it should work from here.
@@SimplilearnOfficial Please describe all steps.
Great presentation. Small update, Lambda is billed using using 1 ms granularity, as of Dec 2020, instead of 100 ms
Hey, thanks for the nice tutorial. If you would have included how to trigger events in S3 using event notifications, that would have made it easy to follow along. Please keep posting such knowledgeable tutorials. đ

Does the user need to setup the configuration of the container that Lambda would use to run the code?
I really like the format of the video. It was very organized and easy to follow.
Awesome, thank you!
Cool and simple explanation Thank you for this video.

"This helps in reducing conflict between teams running different software in the same infrastructure"? Did you mean the same software on different infrastructure?
Good explanation!! Thanks!! But one thing i miss here is how to creat events that triggers lambda

create events that triggers lambda
where is an error i got while running the script. "errorType": "TypeError",
"errorMessage": "Cannot read property '0' of undefined",
"trace": [
"TypeError: Cannot read property '0' of undefined",
Great explanation with easy use case
Glad it was helpful!
Beautifully explained sir
Thanks and welcome!

2 minutes in i already know this is a great introduction course, thanks !
WooHoo! We are so happy you love our videos. Please do keep checking back in. We put up new videos every day on all your favourite topics Have a good day!
perfect explanation. Thanks
How event got triggered ? Don't neee to configure anything to trigger event ?
we have to learn a lot of code or new coding technology in order to be familiar with Lambda, right? your example used Node.js, javascript, etc. If one not using it at work after graduate 15+ years from school, forgot a lot. What's the most common used coding language in Lambda, or in general AWS as Cloud ?
Presentation is good and theory is covered well. Good Job !! However, some of the steps that were pre done like creating s3 trigger, configuring Lambda etc are missing... make changes if you can and upload the video.
excellent way of explanation. Awesome. God bless you.

Nice, thanks!
Our pleasure!
hi, i added the code below, but i dont see the file in my bkp bucket. what am i doing wrong?
let AWS = require("aws-sdk");
exports.handler = async (event) => {
let s3 = new AWS.S3();
let srcBucket = "rad-bucket";
let bkpBucket = "rad-backups-bucket";
let objKey = event.Records[0].s3.object.key;
console.log("objKey is "+objKey);
let copySrc = encodeURI(srcBucket+"/"+objKey);
let copyParams = {Bucket:bkpBucket,CopySource:copySrc, Key:objKey};
s3.copyObject(copyParams, function (err,data) {
if(err)
console.log('it failed with err '+err.stack);
else
console.log('upload and copy successful');
});
};
Nice Explanation
Thanks and welcome
first of all, thank you for the tutorial, crash-videos does help.
i have a question sir.
Time-14:51. the templates, do you have any github where they are stored? (i am not able to find the documentation of these codes and is stuck at my lab work)
a prompt response would be highly appreciated.
Excellent example
Thank you for watching!
good explanation

Thanks for the session, for the same task we can enable CRR in S3 service itself right. than writing this much code.
Hey Venkatarama, this demo was just to demonstrate how you can use the Lambda service with other services. Just to help elaborate on the concepts.
Such a great lecture

Hi sir, I have one doubt:
Suppose I have one IOT device waiting to receive message over MQTT
(subscribed to the topic as well). Can I send MQTT message from Lambda
to that Iot device?
Is it possible to send from AWS Lambda?
Let me check
At first glance this seems comprehensive but unfortunately, it is not. There seems to be quite a few missing pieces to get this to work.

Thank dude, nice explanation.
Glad it helped!
I got to the end where he creates the lambda function but for me the interface is different. Maybe Amazon updated it since 4 years ago. I don't see where the roles are attached. I upload something to the source bucket and it doesn't appear in the destination.
really excellent explanation. Thanks
Greetings! Thank you for your kind words. Spread the word by liking, sharing and subscribing to our channel! Cheers :).
Actually creating the function starts at 12:14.
Hi Milo, we thought it would be best to add some context before jumping right into creating the function...we thought it would help the beginners get accustomed to the concepts.
Oh, agreed, Simplilearn. I just thought that some people might want to skip the veggies and go straight to the meat.
Haha! That's Nice! Thanks for your input then.
Instead of using lambda with so many script, can't we use cross site replceiation for two buckets, its much easier ?
Although the same process can be done in a number of different ways, the objective of the example was to give users an example of how Lambda can be used to solve the use case. Hope that helps!
Simple and effective. Thank you.
Great that you liked the tutorial! If you agree that learning AWS is a good career move, Please refer to this, www.simplilearn.com/cloud-solutions-architect-masters-program-training.
Presentation is Awesome

Super tutorial
Hi Purushottam, we appreciate the kind comment! enjoy!
Really Great ...!
Hi Nagarajan, we appreciate the kind comment! enjoy!
Thanks for the tutorials.. Very helpful.. I would like to know who will be writing lambda functions..? DevOps Engineer responsibilities from aws lambda perspective..?
Hey Manne, we're glad you like our tutorials.
The lambda functions can be created by solutions architects. Although a DevOps Engineer doesn't have to explicitly be involved in the writing of the functions, he/ she is required to have technical expertise regarding the concept. Hope that helps!
Cab you do a video on s3 select

Do we need to know Programming / Coding knowledge to learn AWS ?
Just basics of Python, Linux scripting is required
Can you please provide the codes involved. So that we can make a demo out of it
Hello Sathish, thanks for viewing our tutorial and we hope it is helpful. It would be helpful if you will provide your email ID to us so that we could send the requested dataset promptly.
@@SimplilearnOfficial yes please. I have an error I CANNOT find. Having the code would be very helpful. My email is rebecca_cairns@yahoo.com
Hi, we regret to say that we don't have the code apparently for this video. Sorry for the inconvenience.
In my Account on AWS services IAM role is not present

Thanks a ton!
if possible, please provide code in python which you wrote for node
Hello Ajay, thanks for viewing our tutorial and we hope it is helpful. It would be helpful if you will provide your email ID to us so that we could send the requested dataset promptly.
Hi, I'm trying to send outbound messages from salesforce(when contacts updated i need to sent some data to SQL DB visa Aws lambda functions), i'm not sure how do i parse the soap messages on aws lambda functions. can anyone help me achieve this using C#
"Hey,
We'll go into these implementations in detail in another video. Stay tuned!"
The title should have mentioned that the Lambda function that you are going to use would be in Node, instead of Python.
Thanks for the feedback. We will share this with our team. Thanks.
Hi
I know you are reading a script but please read it as a conversational way.
Thank you for bringing this to our attention. Weâre sorry you had a bad experience. Weâll strive to do better

This was supposed to be for Beginners, but all the roles and events have been already created? Doesn't make any sense with the video and the title.
Hi, sorry to hear that. Could you please explain a bit more on what has gone wrong. So that we can convey it to the concerned team. Thanks!
Summary;
- 12 minutes of waffle
- 5 minutes of outdated and useless technical guidance
