Tale of Two Workloads
![Page 4: Tale of Two Workloads And One Cloud](https://reader031.fdocuments.net/reader031/viewer/2022020306/54b823da4a795940358b463e/html5/thumbnails/4.jpg)
Legacy Design Principles
Monolithic Architecture
Steady State Workloads
Operator Focused

Design Goal: Resilient Infrastructures
![Page 6: Tale of Two Workloads And One Cloud](https://reader031.fdocuments.net/reader031/viewer/2022020306/54b823da4a795940358b463e/html5/thumbnails/6.jpg)
Legacy Infrastructure Consumption Models

Cloud Native Design Principles
Distributed Architecture
Spikey Worloads
Developer Focused

Design Assumption: Fragile Infrastructures
![Page 9: Tale of Two Workloads And One Cloud](https://reader031.fdocuments.net/reader031/viewer/2022020306/54b823da4a795940358b463e/html5/thumbnails/9.jpg)
What’s Wrong with the Cloud?

At Scale Chaos and Failures Are Inevitable

So Design for Failure

Choose Cattle Over Pets
• Pets needs care and feeding – Name the VM – Tune and groom regularly – Feed pets with good food and supplements – Take pets to the vet when they are sick
• Cattle are disposable – Cloud instances are not unique – Tune and groom apps not the cattle – Replace when necessary – Shoot the cattle when it is sick
