My Cloud Story – The Beginning Building virtualization stacks and rudementary “clouds” - Xen, Kvm, iSCSI, DRBD, Pacemaker, etc. Glue, Glue, Glue. Duct Tape, Duct Tape, Duct Tape. - The basics were there, but the management capabilites were not. Proprietary offerings were better but was an issue. Open Source solutions worked but still a bit clunky My Goals: Lowering costs, not so much accelerating productivity 2

Juju? Service Orchestration Framework Originally intended for the cloud (EC2): juju deploy cs:wordpress juju add-relation wordpress haproxy juju add-unit wordpress 12 It would be useful to expand to other providers: juju deploy -e hpcloud cs:hadoop-slave juju add-relation hadoop-slave hadoop-master juju add-unit -n 10 hadoop-slave Also became apparent the same has value on HW: juju deploy -e MAAS cs:nova-compute juju add-relation nova-compute nova-cloud-controller juju add-unit -n 5 nova-compute
