Tale of Two Workloads

Legacy Design Principles

Monolithic Architecture

Steady State Workloads

Operator Focused

Design Goal: Resilient Infrastructures

Legacy Infrastructure Consumption Models

6

On-Prem Infrastructure Managed Hosting

Cloud Native Design Principles

Distributed Architecture

Spikey Worloads

Developer Focused

Design Assumption: Fragile Infrastructures

What’s Wrong with the Cloud?

9

We Architect Cloud Native for Rapid Scale

10

At Scale Chaos and Failures Are Inevitable

11

So Design for Failure

12

Let the Application Handle It’s Own Resiliency

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

Focus on Scaling Horizontally

15

Build Distributed Systems

16

For Example: Think CAP Theorem

17

Cloud Consumption Models

18

Public Cloud Private Cloud

What About Those Pesky Legacy Apps?

Design Architecture For the Workload

20

Legacy Applications

Development Labs & Test

Environments

Mobile Applications

High Performance Computing

Batch processing

Web Applications

Disaster Recovery

21

Co-existence: Infrastructure Silos

22

One Cloud: Multi-hypervisor OpenStack

23

One Cloud: Multi-hypervisor CloudStack

24

CloudStack: Designing for Legacy Apps

25

CloudStack: Designing for Cloud Native Apps
