A quick intro to DevCloud the CloudStack sandbox, and how to use CloudMonkey to manage your cloud. DevCloud is a virtualbox image that contains the CloudStack source code and that is setup to run the storage infrastructure needed by CloudStack plus the networking setup to build the guest network of the VMs. Tiny Linux instances can be started within the Devcloud VM making use of nested virtualization. This is a perfect setup to discover cloudstack, give demos and test new codes. It is used to test new releases and verify basic functionality. You can run DevCloud on your laptop and then use the command line interface CloudMonkey to make API calls to your DevCloud instance. This is the perfect complement to the talk on CloudMonkey and shows the basic functionality of a cloud. Instance creation, snapshots, networking, network offering and AWS EC2 compatibility.

2. IaaS…

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

6. What the ASF did to CloudStack ?

7. • “A little bit about the internals”

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

Cluster N usually with L2 switches.
 Availability Zone has one or

13. “To get your feet wet…”

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 ?

15. Self-Contained

16. DevCloud: as Host
Run CloudStack on local machine
Use DevCloud to setup hosts

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.
