Where does Entry Thingy and my data live?

EntryThingy is a cloud-based solution that runs on AWS EC2 instances. These are basically Linux machines that can be started up when needed and stopped when not needed. It's a cost effective solution for us and many other software providers you're likely used to using.

Your data is stored in two different areas. We use MySQL in a master/slave configuration to store all data except files. The files themselves are stores in Simple Storage Service (S3) buckets. Both S3 and AWS are owned and operated by Amazon. We chose these services to give you access to the same highly scalable, reliable, fast, and inexpensive data storage that Amazon uses to run it's own global network of websites.
