  1. 1. OPENSTACK STL February Meetup 2/17/2015
  2. 2. OpenStack Object Storage - Swift • OpenStack Swift introduction • Releases • Software Architecture • Deployment architecture • Performance benchmarking • OpenStack Swift monitoring • Using OpenStack Swift • Use cases 2
  3. 3. Object Storage • Object Storage (also known as object-based storage) is a storage architecture that manages data as objects, as opposed to other storage architectures like file systems which manage data as a file hierarchy and block storage which manages data as blocks within sectors and tracks. 3 http://en.wikipedia.org/wiki/Object_storage http://storagegaga.com/the-future-is- intelligent-objects/
  4. 4. OpenStack Swift Introduction and History • A distributed object storage system designed to scale from a single machine to thousands of servers. Swift is optimized for multi-tenancy and high concurrency. Swift is ideal for backups, web and mobile content, and any other unstructured data that can grow without bound. • Swift provides a simple, REST-based API fully documented at http://docs.openstack.org/. • Swift was originally developed as the basis for Rackspace's Cloud Files and was open-sourced in 2010 as part of the OpenStack project. 4 https://github.com/openstack/swift
  5. 5. OpenStack Swift Releases 5
  6. 6. OpenStack Swift Contributors 6 http://stackalytics.com/?module=swift-group
  7. 7. OpenStack Swift Key Features 7 • OpenSource • Eventually consistent architecture • Object versioning • API access to objects • Large object support • API throttling • AD/LDAP integration using KeyStone • Zones • Multi-tenancy • Data recovery
  8. 8. Using OpenStack Swift • https://swift.example.com/v1/accoun t/container/object • GET—downloads objects, lists the contents of containers or accounts • PUT—uploads objects, creates containers, overwrites metadata headers • POST—creates containers if they don't exist, updates metadata (accounts or containers), overwrites metadata (objects) • DELETE—deletes objects and containers that are empty • HEAD—retrieves header information for the account, container or object. 8
  9. 9. OpenStack Swift clients • Gladient • Cloudberry Explorer • WebDrive • Cyberduck • S3 browser • python-swiftclient 9

  17. 17. OpenStack Swift Deployment Architecture 17 https://www.swiftstack.com/docs/admin/hardware.html
  18. 18. OpenStack Swift Deployment Hardware Requirements 18 • The Proxy Services are more CPU and network I/O intensive. If you are using 10g networking to the proxy, or are terminating SSL traffic at the proxy, greater CPU power will be required. • The Object, Container, and Account Services (Storage Services) are more disk and network I/O intensive. • Deployment guide available at http://docs.openstack.org/developer/swift/deployment_gui de.html
  19. 19. OpenStack Swift Authentication • Temp Auth • Light weight • The token can be passed into Swift using the X-Auth-Token or the X-Storage-Token header. • KeyStone Auth • Swift is able to authenticate against OpenStack Keystone via the KeystoneAuth middleware. 19 OpenStack Swift by Joe Arnold https://books.google.com/books?id=JbHXBAAAQBAJ&dq=swift+tempauth+%22flat+file%22
  20. 20. OpenStack Swift Performance Benchmarking • Tools • ssbench • swift-bench • Dimensions • Performance • Scalability 20
  21. 21. OpenStack Swift monitoring • What to monitor • Hardware failure • Operating System failure • Swift Cluster health • Swift Cluster telemetry • Tools • Swift Recon • Swift Informant • Statsdlog • StatsD 21
