Virtualization and Cloud are Converging Scale Out Architecture Traditional Apps Scale Up Architecture
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
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
7 “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?
Characteristics of the cloud • Scalability – Shrink & Grow • Instant On / Off • Cost – Bring Billing back to zero
Private Cloud with OpenStack
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
12 How is SUSE Participating? Platinum Member Alan Clark first Chairman of the Board Technical Contributions Promotion in openSUSE Community OpenStack Distribution
SUSE Cloud SUSE Cloud is an open source software solution based on the OpenStack and Crowbar projects that provides the fundamental capabilities for enterprises to deploy Infrastructure-as-a-Service Private Clouds
What is SUSE Cloud? ComputeCompute StorageStorage NetworkingNetworking Abstracts hardware (server, storage, and network infrastructure) into a pool of computing, storage, and connectivity capabilities that are delivered as a service wrapped in the enterprise ecosystem of SUSE.

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
24 Integrate “External Ceph Cluster” Admin Control Compute Ceph-cluster SUSE Cloud as private cloud: ● Cloud nodes deployed by Crowbar ● Cloud nodes run SLES 11 SP3 ● Block Storage: Ceph (cinder) ● Image Service: Ceph (glance) ● Object Storage: Ceph (RadosGW) Ceph- OSD Ceph- mon Ceph- OSD Ceph- RBD Ceph- RBD Ceph- RBD Ceph- RBD cinder crowbar External Ceph Cluster ● Provides “ceph.conf” glance crowbar
25 Set up “Ceph with SUSE Cloud 3” Admin Control Compute Ceph-cluster ● All Nodes deployed by Crowbar ● Block Storage: Ceph (cinder) ● Image Service: Ceph (glance) ● Object Storage: Ceph (RadosGW) Ceph- OSD Ceph- mon Ceph- OSD Ceph- RBD Ceph- RBD Ceph- RBD Ceph- RBD cinder crowbar glance
