One of my daydreams is a common self hosting specification and server that abstracts AWS, Google Cloud and Azure and hosts apps in one click. For example, myflickrr.com/common-host.json can specify Docker images for web and workers, provision them to AWS ElasticBeanStalk, set up scheduled tasks, create a S3 bucket, share a relational DB, set up logs and alarms, provision wildcard emails and captcha with *.mysite.com etc.
