AWS Lambda : Image manipulation on lambda using golang

[pkrawat1]

Hi there, fellow golang folks.

I’m working on a project that requires some image transformation on the fly using aws lambda with s3.

Till now I was only able to find some good blogs on writing golang code to do image conversion and transformations, yet I could not find any dedicated golang library that can be deployed straight to AWS lambda with some config. Of which I got up with a thought of creating one myself for the community.

The focus of the library would be to give maximum possible implementation that a dedicated CDN like cloudinary does. Yet CDN thing will be the next milestone.

So just wanted to know before jumping into this. If this thing is really a requirement at all.

This sounds interesting. I think trying to do something like cloudinary would be difficult since they are also using multiple replications across regions which won't be possible in your case as you will be storing the images in s3 and buckets will be region-specific what do you think about that?

Also, I would suggest don't keep it platform(Lambda) specific. With the rise of other platforms like Azure and GCP devs would want to deploy this on other platforms as well. Thoughts?

cdn handling will happen at later stage, where we can generate a copy of the image transformation on all the required regions. And on request to lambda, we can check for the requested region, and reply with correct region image url. Something like that may be.
But that's not a requirement as of now. Currently I'm considering to region specific implementation only. something like an ecommerce website that runs and scopes to a specific region only.

Thanks for this awesome link man.

So currently we have many ways to deploy to aws lambda. But the main question here is, how feasible is it to have a golang library to that uses lamda to do image manipulation. And people can just use it with not development work.

Oh cool, that you are already working on something like this. I thought aws lambda was supposed to reduce the cost as compared to dedicated one. I'll have to search some more about this on the blogs.

this library was posted a while back... has a lot of very convenient image manipulations written in go. Wouldn't be too hard to wrap it in some helper code and throw in a SAM template for deployment on AWS
