Elastic Overkill: Is Cloud Really The Be-All End-All? Infrastructure.Next Ghent

Published on

As shiny and new as the cloud is, a case can be made that for the most part, business processes can be easily accomodated with cost-saving virtual data centers without the software-defined features of the cloud. With centralized management tools like oVirt leading the way to fast, efficient and low-cost VM deployment,virtual data centers can be just the solution many organizations need now--and the foundation for cloud-based growth later.

  • Founded in 1995, Amazon soon became one of the flagship user of cloud technologies, thanks to Christmas and holiday buying patterns that placed massive seasonal loads on their servers.
    Which they then decided to rent out.
  • Elasticity and automation of resources is the key to cloud computing.
  • In The Cloud, No One Cares If You're A Suit
  • From an IT perspective, work is about delivering services to the end user. At a fundamental level, it does not matter if you are providing services to 10 users or 1000.
  • It's all about one provider...
  • ...and one user.
  • But the world is not virtual. It's still a one-to-many relationship.
  • Coding for cloud (automation, scalability) is not necessary.
    Easier migration
    Faster return on investment
  • Fewer, bigger servers
  • Oversubscribed services get more hardware
  • Fault tolerance
    High availability
    Live migration
    Quality of Service
    Network
    Disk
    Compute
    Memory
  • Add more hardware and modify resources allocated to VM on the fly
  • Coding for cloud (automation, scalability) is not necessary.
  • Large-scale centralized management for server and desktop virtualization.
  • Based on leading performance, scalability and security infrastructures.
  • Open source vCenter/vSphere alternative
  • Merit-based open governance model
    Built using the best concepts from the Apache and Eclipse foundations.
    Governance split between board and projects
    oVirt Projects
    Multiple Projects under the oVirt brand
  • Merit-based open governance model
    Built using the best concepts from the Apache and Eclipse foundations.
    Governance split between board and projects
    oVirt Projects
    Multiple Projects under the oVirt brand
  • JBoss-based Java application
    Communicates with hypervisor nodes
    Manages VM lifecycle
    Controlled with
    Admin Portal
    User Portal
    REST API
    Python SDK
    CLI
  • Stand-alone hypervisor
    Small footprint ~170 MB
    Customized “spin” of Fedora and CentOS with KVM
    “Just enough” Fedora to run virtual machines
    Runs on all RHEL/CentOS hardware with Intel VT/AMD-V CPUs
    Easy to install, configure, and upgrade
    PXE boot, USB boot, CD, or hard drive
    Full Host
    Fedora, RHEL or CentOS host, with an installed VDSM and libvirt to act as a hypervisor
    Flexible
    Add monitoring agents, scripts, etc.
    Leverage existing OS infrastructure
    Hybrid mode capable
  • Local storage on the VMs
    Storage domains such as
    NFS
    iSCSI
    Fibre Channel
    POSIX storage (Gluster)
    Storage domains
    Disk images for Vms
    Exported Vms
    .ISO images for installation media
  • A subset of the OpenStack Basic Tenants
    Scalability and elasticity are the main goals
    Any feature that limits our main goals must be optional
    All required components must be horizontally scalable
    Always use shared-nothing architecture
  • Scale Up
    Servers are like pets.
    Pets are given names, are unique, lovingly hand raised and cared for. When they get ill, you nurse them back to health
    Scale Out
    Servers are like cattle.
    Cattle are given numbers and are almost identical to each other. When they get ill, you get another one.
  • Shared image storage with Glance
    Shared block storage (Gluster, NFS, iSCSI, FCoE for oVirt, Cinder for OpenStack, consuming same storage)
    Shared SDN framework (define oVirt VLANS with Neutron)
    Ability to monitor and control oVirt VMs in Horizon
    Freedom to gradually migrate “old” to “new”
  • Get virtualization savings now, with cloud complexity
    “Single pane of glass” to allow management of traditional virtualization and private and public IaaS
    Enables policy enforcement
    Facilitates service migration
    Frees you from vendor lock-in
    CloudForms Management Engine – Open Sourcing soon.
