What is Object Storage?

By | AWS, Cloud, Oracle | No Comments

By Franck Pachot . I’ve always been working with databases. Before the cloud era, the most abstract term was “data”. A variable in memory is data. A file is data. A block of disk contains data.

My colleagues were laughing for minutes – my Senegalese followers will understand…
