  • CloudStack is open source cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisors such as KVM, vSphere, and XenServer/XCP for virtualization. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API.
  • Talk about Open Source & APACHE!!!
  • A user can belong to only one Account, .ie. the same User cannot belong to multiple Accounts.Whenever creating an account at any domain level it can be of two types - Admin or user. If account == Admin then he will be domain admin of that domain and if created with type=user he will be a regular account under that domain.Admin created at ROOT level is called ROOT admin and since ROOT is the top domain he has privileges to act on all the resources.Username is unique in a Domain across Accounts in that Domain. The same username can exist in other domains, including subdomains.Account name is unique in a domain. The same Account name can exist in other domains, including subdomains.Domain name can repeat as long as the full pathname from ROOT is unique. For ex, you can have ROOT/d1, as well as ROOT/foo/d1, and ROOT/bar/d1.Resources belong to an Account, not individual users in that account. Billing, resource limits etc are maintained by Account, not usernames.CloudStack allows to create 3 different types of accounts --> admin/domain-admin or user account. All the roles (admin, domain admins and user) are attached at account level.Under the account all the users have the same privileges. There are no role based users in one account.We can have multiple admins for the same domain.All the domains get created under the ROOT domain.
  • The first thing to understand is the process of provisioning primary storage. When you create a primary storage pool for any given cluster, the CloudStack management server tells each hosts’ hypervisor to mount the NFS share or (iSCSI LUN). The storage pool will be presented within the hypervisor as a datastore (VMware), storage repository (XenServer/XCP) or a mount point (KVM), the important point is that it is the hypervisor itself that communicates with the primary storage, the CloudStack management server only communicates with the host hypervisor.(http://www.shapeblue.com/2013/02/12/cloudstack-primary-storage/)

    1. 1. Taking the Open Cloud to 11 with CloudStack! Joe Brockmeier PPMC Member – Apache CloudStack Open Source Cloud Computing Evangelist – Citrix Twitter: @jzb | Email: jzb@apache.org
    2. 2. What This Talk is About(Aside from kittens, unicorns, and rainbows.)
    3. 3. Cloud, blah, blah, blah• When thinking about “cloud” we mean: – On Demand, Self-Service – Broad Network Access – Resource Pooling – Rapid Elasticity – Measured Service – API
    4. 4. In Other Words: Solving Real Problems• Eliminating Virtual Sprawl• Programmatic Access to Infrastructure• Self-Provisioning for Customers via GUI or API• Maximizing Resources• Hosting Dual Workloads (Legacy and Cloud)• Robust, Scalable, Fashionable** That last one, maybe not so much.
    5. 5. So… What is CloudStack?
    6. 6. CloudStack History (so far)
    7. 7. CloudStack Design Goals• Multi-tenancy• Broad Hardware/Hypervisor Support• Orchestrate Hardware Resources that may be behind a firewall• Horizontally scalable management layer• Beautiful and Functional UI
    8. 8. High-Level FeaturesA set of applications that:• Provide separation between tenants• Handle allocating compute resources (inc. custom allocators)• Let users provision compute resources• Manage High Availability• Massively scalable (thousands of nodes)• Resource usage accounting• And more…
    9. 9. Management Server• UI/API bits are stateless (state is stored in a MySQL database)• All UI functionality is available as an API call• Restful API – Unauthenticated API on 8096 for localhost (disabled by default) – Authenticated on port 8080 – Responses in XML or JSON
    10. 10. Domains, Projects, and Users• CloudStack has a top-level domain called ROOT• You can create sub-domains• You can create 3 types of accounts, admins, domain-admins, or users• Projects can be used to hold resources for time-limited projects
    11. 11. Hypervisor Support• KVM• XenServer• Xen Cloud Platform• VMware via vCenter• Bare Metal via IPMI
    12. 12. CloudStack Primary Storage• Where the VMs volumes reside.• Supports NFS, iSCSI, Clustered Logical Volume Manager, and others. (Depends on hypervisor)• Hypervisor communicates with primary storage – mgmt server only communicates with host hypevisor.• You can use local storage, but lose some features.
    13. 13. CloudStack Secondary Storage• Stores templates, ISOs, and snapshots• Historically NFS – added the option of object storage recently – Includes Swift, GlusterFS, Ceph and others (in various states of production readiness)• Managed by Secondary Storage VM – – Manages moving templates and snapshots from/to primary storage, aging out snapshots, etc.
    14. 14. CloudStack Allocation• How are VMs placed, storage allocated, etc.?• CloudStack has several defaults – First fit – Fill first – Disperse• Don’t like those? Create your own!• Allows over-provsioning• OS Preference
    15. 15. RFMTTR (High Availability)• RFMTTR – “really fast mean time to recovery.”• CloudStack is not (alone) a magical HA solution.• Watches HA-enabled VMs to ensure they’re up, and that the hypervisor it’s on is up. Will restart on another if the hypervisor goes down.• Redundant router.
    16. 16. CloudStack Networking• CloudStack manages – DHCP – VLAN allocation – Firewall – NAT/Port forwarding – Routing – VPN – Load Balancing• CloudStack can manage physical network hardware (F5-Big IP, NetScaler, Juniper SRX)
    17. 17. Misc. Features• Usage Accounting• UI is Easily Re-Themed / Replaced• Over-Provisioning• LDAP Integration• Notification and Capacity Thresholds• CloudMonkey CLI• Much more!
    18. 18. Getting Started• Visit CloudStack.org• Start with RPMs or Debian Packages (CentOS/RHEL 6.3 and Ubuntu LTS 12.04 supported)• Sign up for cloudstack- users@incubator.apache.org• Talk to us! #cloudstack on Freenode
    19. 19. Demo Time?
    20. 20. That’s All! Thanks! Joe Brockmeier jzb@apache.org@jzb on Twitter / jzb on Freenode
