Alternative to AWS lambda when deployment package is greater than 250MB?

When I want to launch some code serverless, I use AWS Lambda. However, this time my deployment package is greater than 250MB.

So I can't deploy it on a Lambda...

I want to know what are the alternatives in this case?

I'd question your architecture. If you are running into problems with how AWS has designed a service (i.e. lambda 250mb max size) its likely you are using the service in a way it wasn't intended.

An anti-pattern I often see is people stuffing all their code into one function. Similar to how you'd deploy all your code to a single server. This is not really the use case for AWS lambda.

Does your function do one thing? If not, refactor it out into different functions doing different things. This may help remove dependencies when you split into multiple functions.

Another thing you can look at is can you code the function in a different language (another reason to keep functions small). I once had a lambda function in python that went over 250mb. When I looked at solving the same problem with node.js, my function size dropped to 20mb.

One thing you can do is before run the lambda function you can download the dependencies to /tmp folder from s3 bucket and then add it to python path, it would give you extra 512MB, although you need to take into consideration the download time for some of the lambda invocations
