Storage: S3

Hashtable in the cloud

Fundamentally, you can think of S3 as a highly-durable hash table in the cloud. The key can be any string, and the value any blob of data up to 5 TB. When you upload or download S3 objects, there’s an initial delay of around 20 ms before the data gets streamed at a rate of around 90 MB/s. You can have as many parallel uploads and downloads as you want, thus, the infinite bandwidth. You can also store as many objects as you want and use as much volume as you need, without either having to provision capacity in advance or experiencing any performance degradation as the scale increases.
