Editor's Notes
- 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

- 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.
