    1. 1. Building FOSS Clouds Sebastien Goasguen, Kris Buytaert LinuxCon EU, Nov 6th Barcelona, SpainSlides at: slideshare.net/sebastiengoasguen
    2. 2. Speakers…• Joe stayed home to deal with the release,• Kris Buytaert stepped in:
    3. 3. Tutorial Outline• 10:10 – 10:45 FOSS Clouds and CloudStack intro• 10:45 – 11:00 DevCloud demo• 11:00 – 11:50 FOSS Cloud Automation, DevOps configuration and monitoring tools
    4. 4. Define:tutorial• A tutorial is a method of transferring knowledge and may be used as a part of a learning process. More interactive and specific than a book or a lecture…<snip>• Therefore:
    5. 5. DevCloud• A CloudStack sandbox – Pass the USB keys around and get the Vbox appliance devcloud.ova file• Import the appliance in VirtualBox – Play with CloudStack – http://wiki.cloudstack.org/display/COMM/DevCloud – https://cwiki.apache.org/confluence/display/CLOUDSTA CK/CloudStack+devcloud+environment+setup
    6. 6. Objectives• Learn the basic architecture of a cloud• Learn a few new tools• Explore CloudStack via its sandbox• Discover some concepts of automation• Get home with some ideas to try out• Mileage may vary
    7. 7. NIST Definition of Cloud• "cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.“ – NIST
    8. 8. NIST Service/Deployment Models• Service Models: • IaaS (e.g EC2, rackspace) • PaaS (e.g GAE, Azure) • SaaS (e.g Gapps)• Deployment model: • Private cloud • Public cloud • Hybrid cloud (Private than can use Public)
    9. 9. NIST Key Characteristics of Cloud• Elasticity • Expands and Shrinks as needed • E.g Elastic Load Balancing, Elastic Map Reduce• Measured Service • Utility Pricing. You pay for what you use • E.g $0.08 for one hour of small instance• On-demand • You get it when you ask for it • E.g One api call and you get your machine, ~no queue
    10. 10. “Guidelines”• Virtualization and automation are key enablers of the cloud characteristics• Build your infrastructure to enable on- demand elastic provisioning of –servers, storage, network –• Setup a PaaS that suits you and your applications• Then move to continuous delivery of applications …
    11. 11. OSS SaaS…and more
    12. 12. OSS PaaS…
    13. 13. OSS IaaS…
    14. 14. 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…

    16. 16. Announcing Apache CloudStack 4.0
    17. 17. Coming at 12:00 EST• Apache CloudStack 4.0• Check out the testing procedure: – https://cwiki.apache.org/CLOUDSTACK/cloudstack -40-test-procedure.html• Or watch my amazing screencast: – http://vimeo.com/52150218
    18. 18. A bit of History• Original company VMOPs (2008) – Founded by Sheng Liang former lead dev on JVM• Open source (GPLv3) as CloudStack• Acquired by Citrix (July 2011)• Relicensed under ASL v2 April 3, 2012• Accepted as Apache Incubating Project April 16, 2012• First Apache (ACS 4.0) release expected now
    19. 19. Apache Software Foundation
    20. 20. Apache Process• 100% community driven• New ideas, decisions only taken on mailing lists. Votes taken by community• Project led by Project Management Committee (PMC): – http://www.apache.org/dev/pmc.html – http://incubator.apache.org/guides/committer.html• Non committers get invited as committers: – http://community.apache.org/newcommitter.html
    21. 21. Apache Processes
    22. 22. Contributions Examples: Sungard: Announced that 6 developers were joining the Apache project Schuberg Philis: Big contribution in building/packaging and Nicira support Go Daddy: Early proto of Maven building Caringo: Support for own object store Basho: Devcloud packaging
    23. 23. A Very Flexible IaaS PlatformCompute HypervisorStorage Block & Object Primary Storage Secondary StorageNetwork Network & Network Services http://www.slideshare.net/cloudstack/cloudstack-architecture
    24. 24. Architecture / Language• Java application• Tomcat6, Axis2, Maven build + ant – Ant going away in 4.1• Collaboration Conference, Nov 30th -Dec 2nd – http://collab12.cloudstack.org/
    25. 25. Build and Run in 4.1• git clone https://git-wip- us.apache.org/repos/asf/incubat or-cloudstack.git• mvn clean• mvn install• mvn –P developer –pl developer –Ddeploydb• mvn –pl :cloud-client-ui jetty:run

    27. 27. Terminology Zone: Availability zone, aka Regions. Could be worldwide. Different data centers Pods: Racks or aisles in a data center Clusters: Group of machines with a common type of Hypervisor Host: A Single server Primary Storage: Shared storage across a cluster Secondary Storage: Shared storage in a single Zone
    28. 28. Storage• Primary Storage: – Anything that can be mounted on the node of a cluster. – Cluster LVM…iSCSI… – Holds disk images of running VMs – Support for CEPH with KVM hypervisors• Secondary Storage: – Available across the zone – Holds snapshots and templates (image repo) – Can use Openstack swift or any object store (Gluster FS…) – New support for Caringo• Can use NFS for both to start• Storage Abstraction refactoring underway
    29. 29. Networking• Extremely flexible to: – Provide isolation with VLANs – Provide isolation at L3 with shared L2 (scalability) – Support hardware devices that exposes API – Deployed on existing networking infrastructure – Support new networking paradigm (SDN) • Support for Nicira Virtual P • Extensive use of Open VSwitch
    30. 30. A customizable GUI AJAX + API
    31. 31. A very extensive API
    32. 32. API• Not really REST• A set of methods available over http(s)• Unauthenticated on integration port• Authenticated on 8080 using Access and Secret Key• Python/Ruby clients available• Internal Marvin client• Cloudmonkey CLI• Other clouds client support the API
    33. 33. Enabling EC2 and S3• Via the GUI• Via API call on integration API port 8096 http://localhost:8096/client/api? command=updateConfiguration&name=enable.s3.api&value=true http://localhost:8096/client/api? command=updateConfiguration&name=enable.ec2.api&value=true
    34. 34. DevCloud• Several use cases: – Try CloudStack in an isolated sandbox. Runs within the appliance – Develop CloudStack on own machine, build locally and deploy new version in DevCloud (Build and test) – Develop and Run locally, use DevCloud as Xen hosts
    35. 35. DevCloud: self-containedCloudStack runs in the appliance
    36. 36. Testing “4.0” code in DevCloud• Deploy new CloudStack code in self-contained DevCloud:• mvn –P deps• ant rdeploy• ant rdeploydb – Wipes database of mgt server, you will need to reconfigure the “data center”• ant rdebug
    37. 37. DevCloud: as HostRun CloudStack on local machineUse DevCloud to setup hosts
    38. 38. DevCloud to test 4.1 branch• mvn -P developer clean• mvn -P developer install• mvn -P developer -pl developer –Ddeploydb• mvn -P developer -pl tools/devcloud – Ddeploydb• mvn -pl :cloud-client-ui jetty:runConfigure infrastructure:• mvn -P developer,deploysvr -pl tools/devcloud -Ddeploysvr
    39. 39. Testing Framework –for the PyUG  [environment]• Marvin is a Python dns=10.147.28.6 mshost=10.147.39.69 based framework to run mysql.host=10.147.39.69 tests against a [cloudstack] private.gateway=10.147.40.1 CloudStack install private.pod.startip=10.147.41.121 private.pod.endip=10.147.41.160• Could be used as a private.netmask=255.255.254.0 public.gateway=10.147.40.1 simulator of a public.vlan.startip=10.147.41.162 datacenter public.vlan.endip=10.147.41.200 public.netmask=255.255.254.0• Used to configure an hypervisor=XenServer host=10.147.40.10 infrastructure on a mgt host.password=password #storage pools server primary.pool=nfs://10.147.28.7:/expo rt/home/automation/sadhu/primary secondary.pool=nfs://10.147.28.6:/ex port/home/automation/sadhu/secondary
