AWS Elastic Beanstalk upload high amount of data

I am using AWS Elastic Beanstalk and i am want to upload 4GB of wordpress website to it.

I thought i will upload it to Bit Bucket & then via Codeship upload it to AWS S3 but Bit Bucket has repository limit of maximum 2 GB.

Is there some way to upload high amount of data on AWS Elastic bean stalk. e.g via FTP or something. Also even if connection breaks ability to resume the upload from where it broke.

I am a PHP developer and not much into Linux server configurations.

Thank You.
