if this is targeting beginners, would be better to differentiate function from function execution context, function invocations, etc. you say in the "cold starts" section that the function doesn't exist. Well, it exists, but the execution context needs to be created and run the function.
Every time I need to know something, it seems like you'veve just finished releasing a crash course on it. You deserve way more subscribers! Thanks for the amazing content!
"Thousands of request per hour".... You can easily achieve that even with a single VM. I think that scaling starts to be interesting when you have at least "Thousands of request per *second*".
Engaging stuff! If it resonates, the book I'd tip you off to will astonish. "AWS Unleashed: Mastering Amazon Web Services for Software Engineers" by Harrison Quill
Very good video, watching it again after a long time :) One question - when you redeploy the infrastrucure, ARN name of the DynamoDB table doesn't change?
Deployment was done twice, first to create TodoTable in DynamoDB, second when iamRoleStatements was declared to access TodoTable (which required mentioning it's ARN). Can this be done in one single step? (If we don't have ARN beforehand)?
Hey I have a question about passing the "completed" property. Since it wasn't filtered / checked isn't it like some kind of security issue? Or does aws sanitize the props by itself?
Great content as always, just wanted to say if anyone wants to take all the services down they can do the "serverless remove" command in the same path of the serverless.yml file
very good content bro, I have been trying to understand lambda functions for long time but with this crash course you made every thing clear for me. thank you somuch..
You are doing a really great job. Your video is of the highest quality and great knowledge. Keep going and add more vedio on function and cloud formation.
Simple and to the point. This course content is lighweight with core content for overall understanding of serverless architecture using Nodejs. Exactly what I was looking for and exactly where a person should start from. Kudos to your efforts this is a great course. Cheers!
Thank you very much. Very well structured and very easy to follow, big picture to details. One feedback: I increased the speed to 1.75x and that was the speed I was comfortable listening to. This reduced the time to 50min which might increase also your video to get more views, as making the decision to watch 1.5h to learn this was a hard choice to make at the beginning. But now watching this, I can say it was worth every minute.
When i use serverless deploy -v to deploy its literally doing nothing, just gives me framework core, plugin and sdk versions. AND SLS deploy-v keeps on asking for bunch of path params, i enter and it keeps on asking further.This is my first time doing this ,please help!
There is. The thing that makes it "serverless" is that you aren't paying to have a server available all the time. You are instead paying to use a server as requests come in.
hello so i watch your video, but I noticed, I don't get any tables created in my dynamodb , as in the put and promise didn't work for me, I don't know why... could you help
I have a question, If one of the con's of serverless like you mentioned is that it cannot support long running process like uploading a video, is that not a feature netflix should be worried about? since they are in the business of Video streaming
thank you for this course, but i have question about IAM, Did i create IAM role for all My lambda functions based on it need? AND how manage all keys in AWS CLI
Great course man! thank you!. few questions though. the serverless.yml schema, any course to know how to build it? it seems most of the structure its right there.... What about authentication?
i was able to follow the course, up to the section that you wrote serverless deploy -v in vs code terminal, it doesn't do the same thing, instead showed me some info about framework core, plugin, and sdk, any idea why?
I don't know anything about serverless but crash course help me to clear the concept hey Laith Harb can you make a video on a simple MERN application which has authentication how make it serverless and add lambda function I really want to see to because there is no tutorial in the youtube on this concept please make an video on this
Serverless is just technical mumbo jumbo. There is of course still a server involved with the API Gateway as well as the serverless functions themselves! They gotta be stored somehow. I look at serverless as just meaning you don’t have to worry about servers; that’s not to say they aren’t still involved. All you gotta worry about though is building your lambda, deploying it, and setting up a gateway route to the lambda.
Pay-per-use ≠ Cheap ... I think that at the end of the day you spend way less if you have a server, rather than paying for each request (i.e. a service can receive millions of requests in a few minutes). It would be interesting to have some real-world data, where we compare the same website running on servers vs Lambda.
I definitely agree with you, but Lambdas invocation rate can always be limited through the API Gateway, although it may not provide that much help in the case of a determined malicious actor.
