creating open source software to build public and private clouds
OpenStack Mission
‣ “To produce the ubiquitous open source cloud computing platform that will meet
the needs of public and private cloud providers regardless of size, by being
simple to implement and massively scalable.”
Why is OpenStack important?
‣ Open eliminates vendor lock-in
‣ Working together, we all go faster
‣ Freedom to federate, or move between clouds
OpenStack Founding Principles
‣ Apache 2.0 license (OSI), no paid ‘enterprise’ version
‣ Open design process, 2x year public Design Summits
‣ Publicly available source code repository
‣ All community processes documented and transparent
‣ Commitment to drive and adopt open standards
‣ Modular design for deployment flexibility via APIs
Architect for in-house
Re-Architect for service provider
Architect once Deploy anywhere
No Standards

OpenStack Compute DetailsSoftware to provision virtual machines on standard hardware at massive scale.
Asynchronous eventually consistent
communication
REST-based API
Horizontally and massively scalable
Hypervisor agnostic: support for Xen ,XenServer, Hyper-
V, KVM, UML and ESX is coming Hardware agnostic: standard hardware, RAID not required
OpenStack Compute Key Features
API: Receives HTTP requests, converts commands to/from API format, and sends requests to cloud controller
Cloud Controller: Global state of system, talks to LDAP, OpenStack Object Storage, and node/storage workers through a queue
User Manager
ATAoE / iSCSI
Host Machines: workers that spawn instances

OpenStack Object Storage DetailsSoftware to reliably store billions of objects distributed across standard hardware
REST-based API Data distributed evenly throughout system
Hardware agnostic: standard hardware, RAID not required
OpenStack Object Storage Key Features
No centraldatabase
Scalable to multiple petabytes, billions of objects
Account/Container/Object structure (not file system, no nesting) plus Replication (N copies of accounts, containers, objects)

Hardware Selection
‣ OpenStack is designed to run on industry standard hardware with flexible configurations
‣ Compute
‣ X86 Server
‣ Storage flexible (Local, SAN, NAS)
‣ Object Storage
‣ X86 Server (other architectures possible)
‣ Do not deploy with RAID (can use controller for case)
OpenStack Release Process: Four Phases

OpenStack Compute ‘Austin’ Release Features
‣ Multi-hypervisor support: KVM, QEMU, User-Mode Linux, Xen and XenServer
‣ Introduces official OpenStack API, while maintaining EC2 API option
‣ New image registry and delivery service, called the Glance project
‣ Support for two network models on compute nodes: VLANs with DHCP and flat with either static IP pools or DHCP
‣ Addition of base scheduling service
‣ Implements WSGI to create a standard API layer with reusable components
‣ Support for user-friendly naming
‣ Refactored ORM and networking code for simpler code that is easier to understand
‣ Addition of SQLAlchemy Database toolkit so users can leverage existing SQL infrastructure
Object Storage ‘Austin’ Release Features‣ Addition of a stats system that produces per-account
hourly summaries of system usage
‣ Ability for users to set ACL’s and grant public access to containers
‣ Support for API access to account and container metadata
‣ Rate limiting was extended to allow requests to be slowed down and support stair stepped rate limits based on container size
‣ WSGI support was improved and pulled into middleware
