1. DevCloud and CloudMonkey in Apache CloudStack

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 That can: 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:
Java
IDE
Ops:
Shell
CLI

6. What the ASF did to CloudStack ?
Caveat: A contributor is identified by sending a single on the –dev or –users mailing list. This graphs plots the number of unique addresses

7. “A little bit about the internals”

8. A Very Flexible IaaS Platform
Compute
XenServer
VMware
KVM
Oracle VM
Bare metal
Hypervisor
Storage
Local Disk
iSCSI
NFS
Fiber Channel
Swift
Block & Object
Primary Storage
Secondary Storage
Network
Network Type
Isolation
Load balancer
Firewall
VPN
Network & Network Services

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
Hypervisor is the basic unit of scale.
Cluster consists of one ore more hosts of same hypervisor
All hosts in cluster have access to shared (primary) storage
Pod is one or more clusters, usually with L2 switches.
Availability Zone has one or more pods, has access to secondary storage.
One or more zones represent cloud
CloudStack Management Server
Zone 1 ….
L3 core
Secondary
Storage
Pod N
Primary
Storage
Pod 1 ….
Cluster N
Access Layer
Host 2
Cluster 1

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
