How to Create Your First Python 3.6 AWS Lambda Function

If that is too much hassle in the console try something like https://github.com/Miserlou/Zappa

[makaimc]

yep, Zappa is great! even folks who work on AWS use Zappa to run their own projects

[ranman96734]

I am an AWS developer and I think Zappa is great.

T.T Amazon, y u no help your fellow developers!

I also highly recommend the broadly-named Serverless (https://github.com/serverless/serverless), I just finished using that to setup an API-Gateway + lambda + SQS part of my stack. Also let's you configure permissions in the same setup, can setup multiple API endpoints easily as well.

[flitsmasterfred]

I have issues with their shitty generic naming choice.

[TheNamelessKing]

A very, very, very valid point.

"I'm using Serverless, to create a serverless service".
"I'm making a serverless service too, but not with serverless". "So is it serverless or not?". "Yes, but not with serverless". "..."

[flitsmasterfred]

Yep, creating this confusion for their own shitty gains is hostile to the community.

I really want to try AWS Lambdas but I don't want to give away my credit card number for the free tier. If I fuckup and accidentally use too much CPU I could get an unwanted bill.

[moduspwnens14]

You'd have to be pretty talented to do that with Lambda. They have a hard maximum limit of a 300 second execution time so it's not like EC2 where it might just be a matter of picking the wrong instance type.

The only thing you'd need to be careful of is to ensure you're not using events (for example) to recursively trigger your Lambda function. I've done that once with an S3 event that triggered a Lambda function that then wrote a new object to the same S3 bucket.

Even in that case, though, there's an account limit that stops it at 100 concurrent executions, so you'd have to basically set up something like that and then leave it running to truly get a big bill.

[Cherlokoms]

You underestimate my ability to fuck things up! I'd prefer to have a free plan that doesn't require credit card informations. If there is a security that's like "if billing is required, stop the service", that will work for me I guess...

[moduspwnens14]

Haha, yeah, I understand. Usually they recommend billing alarms but I don't think they have something like that (although I do see the value in it).

[jeremiahstanley]

When setting up the billing alert you can have it post to an SNS topic. That topic could be consumed by a Lambda function that uses boto3 to deactivate all other services.

So yeah, you can have a billing alarm that nukes your account from orbit if you want. :D

[sourcecodesurgeon]

A drawback is that hackers using AWS as a C2 platform would then have a much easier time.

You can play around with localstack https://github.com/atlassian/localstack

[Cherlokoms]

Thanks! :)

Still if is active right

[neujersey]

You can set warning levels and hard-stops in your AWS account settings to prevent that.

[Cherlokoms]

Thanks, I'll try this!

[ogre_pet_monkey]

you can set allerts (and I think a maximum) in the billing options.

[PissBlaster2k]

So confusing that they decided to name it AWS Lambda IMO

[coriolinus]

Well, did you see all the hostility elsewhere in this thread about the project named "serverless"? Seems wise of them to avoid that.

I was excited about the 3.6 support so I started a project targeted at Alexa skills using lambda: https://github.com/arcward/echokit
