  1. Introduction to DoC Private Cloud http://cloudstack.doc.ic.ac.uk/client

  2. DoC Requirements • Easily provisioned VMs • GUI & API available to complete tasks e.g. creating accounts & Virtual Machines (VMs) • Availability of Shared (NetAPP) & Local disk offerings • Configure memory/cpu/storage, and choose which supported OS to install (eg. Ubuntu, CentOS). • Accounting system for recording and resource-usage. • Users can be root on VMs and install packages.

  3. Available Hardware: • 4 x Dell PowerEdge C6220 compute servers. This is a very dense compute server, with four independent nodes in a two unit chassis. Each node contains two Intel Xeon E5-2690 8-core 2.9GHz processors (32 threads with hyper-threading), 128GB of RAM and two 1TB hard drives. • 2 x IBM System x3750 M4. Each server has four Intel Xeon E5-4650 8-core 2.7GHz processors (64 threads with hyper-threading), 512GB of RAM, two 300GB hard drives and twelve 1TB hard-drives. • 4 x Dell PowerEdge R720. Each server has two Intel Xeon E5-2640 2.50GHz six-core 2.5Ghz processors (24 threads with hyper-threading), 64GB of RAM, two 300GB hard drives and 24 1TB hard-drives. • 1 x NetAppNetApp F2240A-2 dual-controller Filer and disk-shelf; raw storage capacity 60TB. • 4 x Extreme Summit X670 10GbE switches.

  4. Software used for the setup: For CloudStack Management Nodes: • Hardware HA: CentOS Linux Cluster (2 nodes) ==> controls resources: VIP, HAProxy, CS (MGMT & Usage services) & MySQL DB share via iSCSINetApp LUN. • CloudStack Management Interface Load Balanced: HAProxy • Database - MySQL Virtualised Management Farm • Hypervisor: Xen Cloud Platform v1.6 (XCP)  • Support VM migration from local -> shared storage & vice versa

  5. API coding • Cloudmonkey : Python-based command line utility for interacting with Apache CloudStack IaaS clouds • HTTP encoded queries via perl/python/php scripts

  6. CloudStack Lingo • Zones • Pods • Clusters • Domains • Projects • Accounts • Users • Templates/ISO images • Service offerings: System (CPU & RAM) & Disk • Instances (VMs)

  7. Zone

  8. Etiquette • Provide a meaningful display name (hostname). e.g. <userid>-vmxx • Unused VMs should be deleted. • Limit the creation of VMs (as it takes up unnecessary resources and bandwidth) • VMs are not backed up.

  9. User accessibility: • via API commands using API & Secret Keys for authentication • User logins currently linked to LDAP • Local users could be created in a separate domain. • S3 and EC2 API compatibility

  10. Future improvements • CSG Maintained VM Templates • Setup MySQL Galera Cluster (Master - Master) setup • Upgrade CloudStack -> 4.2 (July 2014) • System Usage Accounting

  11. And Finally ... • 3rd year project is currently using it. • Q & A • Demos http://cloudstack.doc.ic.ac.uk/client
