DevCloud and CloudMonkey
- 3. IaaS challenges
• Not out of the box by itself
• Need a farm of hypervisors
– Xen, KVM, VMware…
• Need storage
– For image catalogue
– For volume/snapshot management
• Need flexible network that can be configured
on-demand
– VLANS, no VLANS, existing net infra, SDN…
- 4. IaaS is really:
• A Data Center Orchestrator
– Data storage
– Data movement
– Data processing
• That can:
– Handle failures
– Support large scale
– Be programmed
- 5. DevOps
• Bring your developers closer to the operations
• Make your sys admins develop the apps
• Move to Software Defined Data Center,
Automate everything
Dev: Ops:
Java Shell
IDE CLI

- 9. Architecture / Language
• Java application
• Tomcat6, Axis2, Maven build + ant
– Ant going away in 4.1
• Moving towards a plugin architecture
- 10. Releases
• Apache CloudStack 4.0 released in November
• Time based releases
– Rather slip features but guarantee release
• Apache CloudStack 4.1 planned for March
22nd. 4.2 most likely in July
- 11. CloudStack Cloud Architecture
Internet
Internet Hypervisor is the basic unit of
CloudStack
Management scale.
Server
Zone 1 Cluster consists of one ore
more hosts of same
L3 core
L3 core hypervisor
All hosts in cluster have access
Pod 1 Access Layer
Access Layer Pod N to shared (primary) storage
Secondary
…. Storage Pod is one or more clusters,
Cluster N usually with L2 switches.
Availability Zone has one or
…. more pods, has access to
secondary storage.
Cluster 1
One or more zones represent
Host 11
Host cloud
Primary
Storage

- 14. DevCloud
• A Virtual box appliance packaged to provide a
working CloudStack environment.
• Aimed at developers but has other use cases:
– Xen PV hosts gives nested virtualization
– Local EC2/S3 Cloud on your laptop
– Networking experiments ?
- 17. CloudMonkey
• The CloudStack CLI, developed by Rohit Yadav
• ~600 lines of Python
• pip install cloudmonkey
• Lots of features:
– Auto-completion
– Tabular output
– Help , scriptable, interactive shell…
- 18. Intro
• $ cloudmonkey
• ☁ Apache CloudStack ? cloudmonkey 4.0.0. Type
help or ? to list commands.
