Virtualization and Cloud are Converging

Scale Out ArchitectureTraditional Apps

Scale Up Architecture

5

Issues with Traditional Architecture

• Service requests take too long– More and more clients devices are coming online

– Much harder to maintain service to customers

• Systems can't scale to cope with the demand

• Our Data is too large– Producing vast amounts of data

– Way past the ability of traditional systems and applications

6

A different kind of architecture

Cloud Workloads• Applications scale out: add more VMs

• Stateless VMs, application distributed

• Small VMs: vCPU, vRAM, storage separate

• Application SLA <> of any one VM

• SLA requires to create and destroy VMs where needed

• Lifecycle measured in hours to months

• Applications designed to tolerate failure of VMs

Traditional Workloads• VMs scale up: add vCPU, vRAM etc

• Stateful VMs, application = VM

• Big VMs: vCPU, vRAM, local storage inside VM

• Application SLA = SLA of VM itself

• SLA relies on underlying HA technology

• Lifecycle measured in years

• Applications not designed to tolerate failure of VMs

“Pets” vs “Cattle”What is a perfect cloud workload?

many sheep - numbered - standard images - replaceable nodes - highly automated

some dogs - named - special instances

8

Storage in the Cloud

• New workloads store data separately

• How to handle the large amount of data?

9

Characteristics of the cloud

• Scalability– Shrink & Grow

• Instant On / Off

• Cost– Bring Billing back to zero

Private Cloud with OpenStack

11

What is OpenStack?

● Open source project for building IaaS clouds

● Delivers cloud management platform software

● Strong community with rapid development

● Massive industry involvement

● Quickly maturing technology – 8th release

SUSE Cloud 3 Highlights

• Based on OpenStack Havana‒ Orchestration module (Heat) project for VM orchestration

‒ Telemetry module (Ceilometer) improves cloud measurement

• New Features‒ Full VMware support - in addition to KVM, Xen, Hyper-V

‒ Improved networking and block storage adapter support

‒ Cisco Nexus, EMC, VMware NVP and others

‒ Updated Ceph packages

‒ SUSE Cloud 2 to SUSE Cloud 3 upgrade

‒ Manual addition of existing servers as cloud nodes

• Platform for High Availability ‒ Delivered as update in March

The Most Enterprise Ready OpenStack-Based Private Cloud Solution

Ceph in SUSE Cloud

22

Set up a Ceph cluster for private cloud

• Ceph storage:‒ Ceph OSD – servers with lots of disks to store data

‒ Ceph Mon – monitoring server

• Private cloud:‒ Use Ceph storage for Block Storage, Object Storage and

Image Service

‒ KVM as hypervisor with Ceph RBD

23

Set up (continued)

• How to set up the cluster with 10+ storage nodes and at least 3 monitors?

‒ All storage nodes same setup

‒ All monitors same setup

‒ And integration into SUSE Cloud

• Crowbar can handle this easily
