Making Hybrid Cloud a Reality

Kevin KlugeCloud.com VP Engineering

Agenda

2

• Establish terms• A RightScale / Cloud.com hybrid cloud

solution• Deployment architecture• Demonstration• Future directions

What is a Hybrid Cloud?

3

• Two or more clouds• Some servers on a private cloud• Some servers on a public cloud

– Optionally used for bursting

• Single management interface– Spans both public and private clouds– Enables consistent view of servers across clouds

Hybrid Cloud Prequisites

4

• No need to move large datasets to burst– Simple websites, content systems

OR• Large pipe between public and private

– So big data location doesn’t matter– WAN optimization

Who is Cloud.com?

5

• IaaS software provider– Orchestration layer

• Open Source• Enables secure, multi-tenant, scalable

public and private clouds• GA software since 2009• CloudStack product is RightScale ready

A RightScale / Cloud.com Solution

6

• Private cloud running CloudStack– Physical resource management through CloudStack– Highly Scalable– Server (Guest) management through RightScale

• Public cloud – Any RightScale-managed cloud is sufficient– EC2 in this example

• RightScale manages images, server arrays, and autoscaling across clouds– Provides single management interface

Demonstration Deployment

8

• Private Cloud on CloudStack– Virtual load balancer (HAProxy)– Two HTTP-based app servers

• Public Cloud on EC2– Autoscaling array of app servers

• Load generating client• Result: as load changes on application servers

the public cloud array grows/shrinks in size

Demonstration Implementation

10

• Public cloud array of app servers– Cloudburst tag– Min of 0, max of 10– Same function as private cloud app servers

• Application Servers– Register with load balancer on create

• Regardless of server location

– Vote on array sizing based on CPU utilization• Find array with “cloudburst” tag• Grow at >60% busy, shrink at <30% busy

– Unregister from load balancer on destroy

Future Direction

12

• Deploying a private cloud is challenging– Deployment architecture, fault tolerance– Network configuration– Storage selection– Hypervisor selection– Scalability plan– Security review

• Therefore hybrid clouds are challenging• A SaaS solution can help!

The Cloud Kit for Private or Hybrid

13

• Private cloud with external management– Compute servers (hypervisors) run on customer

premises– Configure compute servers with credentials for SaaS

account– Cloud Kit agent connects to SaaS CloudStack

Management Server

• All user actions through RightScale– Users never see a CloudStack UI– RightScale enables hybrid cloud

The Cloud Kit

14

• Optional public cloud of your choice• Fewer choices easier deployment

– Prescriptive about technology choices– No administrator UI?

• Still scalable– Simplicity helps scale

Summary

16

• Hybrid clouds are here today• RightScale + Cloud.com

– Consistent experience across EC2 and private cloud– Bursting across cloud boundaries

• Private and hybrid clouds can be easy– SaaS can help– CloudStack + Service 2011

• Thanks!
