Understanding cloud applications design principles

In this section, we will cover key guiding principles that are useful while designing cloud-based applications. More specifically, we will introduce designing for scale, automated infrastructure, failures, parallel processing, performance, and eventual consistency.

Designing for scale

Traditionally, designing for scale meant carefully sizing your infrastructure for peak usage and then adding a factor to handle variability in load. At some point, when you reached a certain threshold on CPU, memory, disk (capacity and throughput) or network bandwidth, you would repeat the exercise for handling increased loads and initiate a lengthy procurement and provisioning process.
