CloudStack 4.0 (Incubating) CloudStack 4.0 is the first release as a Apache project. Being released within the hour! Wido den Hollander <wido@widodh.nl> Hugo Trippaers <htrippaers@schubergphilis.com>

What is CloudStack? CloudStack is a Infrastructure-as-a-Service (IaaS) cloud orchestration platform Build to deploy thousands of virtual machines It is Hypervisor agnostic. Supports KVM, OVM, VMWare and XenServer

Why 4.0? Citrix submitted CloudStack to ASF in May 2012 4.0 brings new features Major version change to indicate first Apache release Licensing issues had to be resolved

Licensing for 4.0 Pre-4.0 repository contained non-ASL compatible software and binaries (JARs) Apache projects only release source code Switched to maven to resolve these dependencies

What brings 4.0? Inter-VLAN routing (VPC) Network Virtualization (Nicira NVP L2) RBD primary storage (Ceph) Local storage for data volumes

Virtual Private Cloud

Virtual Private Cloud Multi-tier network configuration support complex applications finegrained network access configuration Site-2-site VPN to link existing networks Dedicated network offerings

Network Virtualization (Nicira NVP) Integration with Nicira Network Virtualization Platform.

Configurable using offerings

Transparent integration

Easy troubleshooting

Network Virtualization (Nicira NVP) Integrate with Nicira Network Virtualization Platform. Transparent integration with Guest Networks Integrated with Physical Network configuration to allow VLAN and SDN networks to co-exist Implementation of SDN networking can be expanded with other SDN implementations Limitations L2 Networking only (until 4.1) KVM not yet supported (patch pending)

RBD (RADOS Block Device) Ceph is a unified open source distributed storage system RBD is a part of the Ceph project No SPoF! (Really, none!) Striped in 4MB chunks over RADOS objects RADOS is the object store of Ceph Reliable Autonomous Distributed Object Store Ceph scales up to PetaBytes even ExaBytes

Ceph

And with multiple VMs? VMs are striped over objects, they probably use different disks High parallel performance More disks means more performance

Ceph

RBD vs NFS and iSCSI NFS and iSCSI still point to one device Some SANs do some stuff with virtual IPs, but it still doesn't scale out RBD scales out by just adding machines Without downtime!

Local storage for data volumes Local storage is useful for example webservers or applications who need very low disk latency CloudStack knows two volumes: root and data In pre-4.0 only root volumes where supported on local storage No migration possible with local storage
