To do that, they had to engineer new ways of extending the growing online service without crashing it. The problem: Building new pieces of functionality required engineers to start coding them from scratch every time. (The audio clips below are from the podcast “Cloud Atlas: How The Cloud R...
Databases can be split into two categories: relational databases and non-relational databases. Relational databases store related data points such as a customer’s name, and email, or account ID.
