In the code of the Scheduling with cron section, we used local targets, writing to the filesystem of our computer. In a real-world scenario, that will rarely suffice—you'll be probably writing either to a database or file stored in the cloud. In fact, we highly encourage you to write tasks to the cloud (for example, S3 buckets) from the get-go, if there is no reason not to. Luigi supports FTP, S3, Azure Blobs, Google Cloud, Spark, MongoDB, SQL databases, and many more. The only question is to create those resources and set up credentials to access them. The best part for many of them is that the interface is very similar, so it is easy to swap targets for existing tasks, by changing only a few lines of code.
