This article at a glance – TL;DR

The Cloud Native foundation as a good source to check new moves from the cloud industry

The content

  1. Cloud-Native Computing Foundation: For an application to be considered truly Cloud Native they need to be:
    1. Built for fault tolerance
    2. Horzontally scalable
    3. Written in a manner that takes full advantage of what cloud providers have to offer.
  2. Cloud Native Applications prioritize the following:
    1. Speed
    2. Short cycles
    3. Microservices
    4. Loosely coupled
    5. DevOps
  3. Pet vs cattle way of handling our servers:

As a developer, you care about the application being hand-cared for − when it is sick, you care of it, and if it dies, then it is not easy to replace. It’s like when you name a pet and take care of it; if one day it is missing, everyone will notice. In the case of cattle, however, you expect that there will always be sick and dead cows as part of daily business; in response, you build redundancies and fault tolerance into the system so that ‘sick cows’ do not affect your business. Basically, each server is identical and if you need more, you create more so that if any particular one becomes unavailable, no one will notice.
