Tale of Two Workloads

4. Legacy Design Principles
Monolithic Architecture
Steady State Workloads
Operator Focused

5. Design Goal: Resilient Infrastructures

6. Legacy Infrastructure Consumption Models

On-Prem Infrastructure Managed Hosting

7. Cloud Native Design Principles
Distributed Architecture
Spikey Worloads
Developer Focused

8. Design Assumption: Fragile Infrastructures

9. What’s Wrong with the Cloud?

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

15. Focus on Scaling Horizontally
