Doing so has a number of benefits - Overcome the 10Mb limit of the API gateway the lambdas have to go through - By storing the key as the hash of the code we can return previous generated assets, i.e. caching - cost, transfering assets into the bucket within the AWS ecosystem is faster than return, and there fore the lambdas execute for less time - Sets us up for the future as when generating artifacts for repos when there is a change to master etc we want to store these assets somewhere and s3 is an obvious choice - Solved a weird CORS issue where I couldn't get CORS working with binaryMediaTypes enabled, don't need binary types when dumping in s3 Resolves #316
