opentelemetry-lambda VS terraform-aws-lambda

I mean, sure, you can improve performance a bit by increasing the RAM/compute capacity on the Lambda. But it always adds a pretty steep overhead right now, no matter how much capacity you throw at it.

OpenTelemetry AWS Lambda repository

With the sample apps from the opentelemetry-lambda repository the Lambda part itself was easy to implement. What took me some time was to provide the jaeger Fargate service with IaC ouside of an k8s environment. But with ECS and ServiceDiscovery that was easy in the end. This should be even more simple in an EKS environment with the jaegertracing helm-charts.

OpenTelemetry recently released https://github.com/open-telemetry/opentelemetry-lambda, but they also have this in the official docs https://opentelemetry.io/docs/instrumentation/js/serverless/. What do you consider to be the better option?

opentelemetry-lambda

You don’t have to create an opentelemetry configuration file such as this for each of your lambdas. In fact, you shouldn’t. In AWS, you can use Lambda Layers. You can define the OpenTelemetry tracing piece of code as a Lambda layer and use it in any Lambda you want. Furthermore, OpenTelemetry went ahead and implemented this opentelemetry-lambda layer for us. All we need to do is use it with our config.

Sorry you're having trouble working with the ADOT Lambda Layers :(. Have you had a chance to open an issue on the GitHub repo for OTel Lambda or ADOT Lambda? You should add your expected vs your actual output!

There are just too many required parameters to create a single handler. And then you need to do that N times for each handler. Take a look at a complete Terraform example for a lambda: https://github.com/terraform-aws-modules/terraform-aws-lambd...

For a personal project it's just a bit much in my experience, especially since most personal projects can easily be served by a t3.micro.

https://github.com/terraform-aws-modules/terraform-aws-lambda/ - this modules has it all. There are various examples and submodules in that repository to help you achieve all your serverless tasks the same way.

It’s also weird not to know about terraform modules. There are a lot of things you _can_ configure because there are a lot of things people need to configure but if you’re using something like https://github.com/terraform-aws-modules/terraform-aws-lambd... it’s only a couple of lines of config for a Lambda.

I use the Community Terraform Lambda Module to define the lambda. It allows me to define a lambda in just a few lines that are configured with a role and can also be easily extended with policies. The cool thing is that cdktf supports a type import. To do this, simply add the following module to the cdktf.json file:

As somebody already mentioned in the comments, you can use the terraform-aws-lambda module as well as many other modules for typical serverless services like API Gateway v2, AppSync, EventBridge, StepFunctions, AppConfig, DynamoDB, and many more.

You can containerize the lambda functions and when you deploy each lambda function, you can overwrite the CMD for each function in the resource block to match what you need. I'm doing something similar but only deploy 2 lambda functions which use the same source code but do very different tasks. I also strongly suggest you use the terraform-aws-lambda module since it will build out all related resources you need.

Have a look at this module: https://github.com/terraform-aws-modules/terraform-aws-lambda

I can't find any open issues on github or anyone asking for it other than in the modules that are provided. https://github.com/terraform-aws-modules/terraform-aws-lambda/issues/128
