When I use the web interface to get my data from the cloud, how does the cloud know where it put my data? There’s a lot of information on how the cloud stores your data, but not how the cloud keeps track of your data.
In: Technology
“The Cloud” is a giant application for sharing server resources in front of some data centers. Amazon, Google, Microsoft, and a few others run cloud services.
Each of these cloud providers have various mechanisms for storing files. For instance, Amazon offers the S3 Bucket storage. They essentially have a giant set of data storage servers for the files, and then a database backed frontend application. When you access the files, you ask that frontend application for the file, it asks its database for the file location, and then it accesses the actual file servers.
The key is that the system is so streamlined, and that the cloud providers give software developers great libraries for integrating the storage. This enables it to be seamlessly integrated into other applications.
