  • 1. 1 OpenStack IaaS Rhys Oxenham September 2013
  • 2. What is OpenStack? ● Fully open source cloud “operating system” ● Provides all of the tools/building blocks required to build a cloud environment from scratch - mimics public clouds ● Started by NASA and Rackspace but now has an independent foundation in which key industry members are present, including Red Hat ● Enormous market hype with investment from all major players, e.g. HP, Dell, IBM... and with 1000's of developers worldwide
  • 3. Why does the world need OpenStack? ● Cloud is widely seen as the next-generation IT delivery model ● Agile & flexible ● Utility-based on-demand consumption ● Self-service drives down overhead and maintenance ● Public clouds setting the benchmark, organisations want the same level of functionality but behind the firewall ● Not all organisations are ready for public cloud ● Applications are being built differently today- ● More tolerant of failure ● Make use of scale-out elastic architectures ● OpenStack enables organisations to achieve this, today... and without lock-in.
  • 4. A different kind of architecture... TRADITIONAL WORKLOADS ● Stateful virtual machines ● Big VMs: vCPU, vRAM, local storage inside VM ● Application SLA aligned to VM itself ● Relies on underlying HA technology to meet SLA goals ● VMs scale up: add vCPU, vRAM, etc. ● Applications not designed to tolerate failure of VMs CLOUD WORKLOADS ● Stateless VMs, application distributed ● Small VMs: vCPU, vRAM, storage separate ● Application SLA not dependent on any one VM ● Many instances can provide application availability ● Applications scale out: add more VMs ● Applications designed to tolerate failure of VMs
  • 5. Or an easier analogy... PETS = TRADITIONAL WORKLOADS FARM ANIMALS = CLOUD WORKLOADS Credit : Tim Bell @ CERN Labs, Bill Baker @ Microsoft, and others ● Pets are given names like ● ● They are unique, lovingly hand raised and cared for ● When they get ill you nurse them back to health ● Farm animals have tag numbers like ● They are almost identical to each other ● When they get ill you get another one
  • 6. OpenStack Release History ● July 2010 - Initial announcement ● October 2010 - Austin Release ● February 2011 - Bexar Release ● April 2011 - Cactus Release ● October 2011 - Diablo Release ● April 2012 - Essex Release ● October 2012 - Folsom Release ● April 2013 - Grizzly Release ● October 2013 - Havana Release
  • 7. What is Red Hat doing about OpenStack?
  • 8. 8 OpenStack Contribution
  • 9. 9 OpenStack Contribution Leading Contributor to Grizzly Release ● Leading in commits and line counts across all projects ● Note: Not including OpenStack dependencies, Linux, KVM, libvirt, etc
  • 10. 10 OpenStack Contribution ● Why do these statistics matter? ● Proof that Red Hat has the skills and resources to... ● Support customers ● Drive new features ● Influence strategy and direction of project ● Not a monopoly! ● We're not in full-control of the project and we don't intend to be ● Our commitment continues to grow ● But, overall contribution percentage in comparison to all contributions is getting smaller
  • 11. OpenStack Progression ● Enterprise-hardened OpenStack software ● Delivered with an enterprise life cycle ● Six-month release cadence offset from community releases to allow testing ● Aimed at long-term production deployments ● Certified hardware and software through the Red Hat OpenStack Cloud Infrastructure Partner Network ● Supported by Red Hat ● Installs on Red Hat Enterprise Linux only ● Latest OpenStack software, packaged in a managed open source community ● Facilitated by Red Hat ● Aimed at architects and developers who want to create, test, collaborate ● Freely available, not for sale ● Six-month release cadence mirroring community ● No certification, no support ● Installs on Red Hat and derivatives ● Open source, community- developed (upstream) software ● Founded by Rackspace Hosting and NASA ● Managed by the OpenStack Foundation ● Vibrant group of developers collaborating on open source cloud infrastructure ● Software distributed under the Apache 2.0 license ● No certifications, no support
  • 12. Community → Enterprise
  • 13. 13 Red Hat OpenStack Offering Red Hat will include the following in its Red Hat OpenStack distribution ● All core OpenStack Grizzly packages including Quantum ● Support for Open vSwitch via userspace tools in Red Hat OpenStack + kernel support in RHEL 6.4 ● Puppet modules for installing all services for OpenStack ● A multi-node installer for small deployments (PackStack) ● Reference architectures for large scale deployments ● Bug-fixes and features selectively back-ported from Havana
  • 14. 14 Release Cadence ● Upstream ● Source code only ● Releases every 6 months ● 2 to 3 'snapshots' including bug fixes ● No more fixes/snapshots after next release ● Upstream RDO ● Follows upstream cadence ● Delivers 'binaries' in yum/rpm format for RHEL, Fedora, etc.
  • 15. 15 Release Cadence ● Red Hat OpenStack ● 6 month release cycle ● Roughly 2 months AFTER upstream ● Time to stabilize, certify, back-port etc. ● Initially 1 year lifecycle ● Support for Folsom ends after Havana release ● Support for Grizzly ends after Icehouse release ● Will increase lifecycle over time ● Based on upstream stability and customer requirements
  • 16. 16 Why Red Hat OpenStack? ● Red Hat brings what OpenStack really needs... ● Supportability ● Stability & Code Maturity ● Certified Ecosystem ● Lifecycle ● Support for the entire stack from one vendor ● OpenStack Components ● Stable, mature and trusted Linux Operating System ● Secure, high performance virtualisation ● Storage ● Software Defined Networking
  • 17. 17 OpenStack moving forward... ● Continued focus on OpenStack core ● Working on core OpenStack components ● Integrating with proven technologies underneath ● Cloud Partnership Program announced to help 3rd parties certify ● Work with vendors providing layered products to build ecosystem ● Integrating with existing Enterprise architecture requirements ● Management tools for RHOS ● Deliver in stages ● Tooling for installation and configuration management (Based around Foreman) ● Centralised Management Platform ● Optional CloudForms Integration
  • 18. OpenStack Architecture
  • 19. OpenStack Components ● Modular architecture ● Vast scale-out design ● Based on a (growing) set of core-components
  • 20. OpenStack Keystone ● Keystone provides a common authentication and authorisation store for OpenStack ● Users, their roles and the tenant (project) they belong to ● Authentication is based on tokens ● 24-hour expiry by default ● Easily revoked if compromised ● Each OpenStack component uses Keystone to verify a users token ● It also provides a catalogue of all other OpenStack services
  • 21. OpenStack Nova ● Core responsibility is to schedule and manage instances (think Amazon EC2) ● Supports multiple hypervisors ● VMware ESX (either direct to ESX or via vCenter) ● Xen ● KVM ● Microsoft Hyper-V ● Exposes an OpenStack API but also an EC2 compatible API
  • 22. OpenStack Glance ● Mechanism for storing and retrieving disk images ● Supports many standard image types ● raw, qcow2, vmdk, vhd, iso, ami/aki, ovf ● With various storage options for the images ● Filesystem (Default) ● Swift (OpenStack Object Storage) ● S3 (Amazon's Simple Storage Service)
  • 23. OpenStack Swift ● Mechanism for storing and retrieving arbitrary unstructured data (as objects) ● Entirely REST-ful HTTP API based, similar to Amazon S3 ● Highly fault tolerant ● Data replication (including geographically) ● Self-healing architecture ● Load-balancing with built-in proxy servers ● No single point of failure ● Doesn't require any specific hardware, purely scale-out.
  • 24. OpenStack Quantum ● OpenStack's Networking-as-a-Service Component ● Implements Software Defined Networking (SDN) ● Rich plugin architecture which allows Quantum to abstract the underlying technology implementation away. ● Cisco UCS ● VMware Nicira ● Open vSwitch etc.
  • 25. OpenStack Cinder ● Provides block storage for runtime of instances ● Can be used for persistent or tiered storage ● Enables ability to do live migration of instances ● Similar to Amazon Elastic Block Storage (EBS) ● Support for many storage vendors platforms for offload ● Default implementation exposes LVM's over iSCSI
  • 26. OpenStack Horizon ● Self-service portal exposing end-user OpenStack functionality ● Web-based interface that utilises underlying API's ● Permits the creation and life-cycle management of ● Instances (including snapshots) ● Images ● Volumes ● Networks ● Has different views depending on whether the user is an administrator or not.
