What is OpenStack?

A community creating open source software to build public and private

clouds

Software to provision virtual machines on standard hardware at massive scale

Software to reliably store billions of objects distributed across standard hardware

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

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

Glance: HTTP + OpenStack Object Storage for server imagesOpenStack Compute

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)

October 2010

• OpenStack Object Storage production-ready• OpenStack Compute developer preview, ready for testing and proofs of concept

• OpenStack Compute ready for enterprise private cloud deployments and mid-size service provider deployments• Enhanced documentation• Easier to install and deploy

•OpenStack Compute ready for large service provider scale deployments

OpenStack Compute ‘Bexar’ Release Features

‣ Object Storage‣ Large objects (greater than 5 GB) ; client-side chunking and segmentation now allows

virtually unlimited object sizes, limited only by the size of the cluster it is being stored into

‣ Experimental S3 compatibility middleware

‣ Swauth authentication and authorization service on top of Object Storage

‣ Compute‣ Support for raw disk images for hypervisors that are libvirt compatible (e.g. KVM) and

XenAPI

‣ IPv6 support in all network modules but FlatManager (coming in Cactus)

‣ Support for new virtual volume backends to provide highly available block volumes for virtual machines: Sheepdog, CEPH/RADOS, and iSCSI (XenApi only)

‣ Microsoft Hyper-V hypervisor is supported

‣ Updated OpenStack API – admin features to pause, suspend, lock, and password reset instances

‣ New “rescue” mode allows an instance to mount affected disks and fix problems

Object Storage ‘Bexar’ Release Features‣ Compute (cont’d)

‣ Web-based serial console to access instances when networking fails is available through the OpenStack API

‣ Database versioning and migration support

‣ Instances now use copy-on write by default for better performance

‣ Support for availability zones through new scheduler: ZoneScheduler

‣ Glance (Image Registry)‣ Registry and Delivery APIs were unified; specific client class created

‣ Support for uploading disk images thru Glance REST-full API

‣ Glance-upload tool can register new AMI-like images or raw disk images

‣ Fetch image data on S3-like backend as well as from Object Storage
