Developed by more than 330 contributors who implemented 185 different features, the OpenStack Folsom release continues the themes of stability and extensibility, while adding significant new features like Networking, Block Storage and Hyper-V support. There was also signficiant progress made with localization efforts, including a new translation framework for user-facing guides and documentation.
Built-in multi-tenancy allows cloud administrators to delegate self-service access to users who can provision cloud resources within customized limits
Newly enhanced functionality allows users to customize more aspects of their compute instances at launch, including the ability to boot directly from shared block storage devices.
With a focus on ease of use, performance, and security, the latest release of OpenStack Compute makes it easier for operators to configure large pools of virtual machines. A new "config drive" capability stores network configuration information, eliminating the need for DHCP, and a new "host aggregation" feature places workloads into the best pools of resources for the job, such as GPU clusters for HPC work. Performance and security enhancements enable users to expose unique features of the CPUs powering their cloud, including support for Trusted Computing, which relies on hardware to verify the cloud computing environment's state.
Among many operational enhancements, operators can now connect OpenStack Object Storage to a statsd server and receive hundreds of real-time metrics about their cluster to help with troubleshooting, diagnostics, day-to-day operational issues, and long-term capacity management. To improve performance, clusters with high write requirements or large quantities of stored objects can now take advantage of solid-state drives (SSDs) for storing metadata without incurring a high overhead in disk space. Additionally, the ability to place data in cluster locations that are “as unique-as-possible,” makes it easier to deploy small clusters and provides better flexibility for all clusters when handling hardware failure.
The first full release of OpenStack Block Storage implements advanced, extensible block and volume storage capabilities, while still supporting previously deployed OpenStack Volumes. Previously a sub-component of OpenStack Compute, the Block Storage capabilities of OpenStack have been promoted to a full project with a dedicated development team that will increase the rate of innovation as the OpenStack development community grows.
An advanced network automation platform that empowers users to choose their back-end technology, OpenStack Networking includes support for Open vSwitch, the Ryu open source network operating system, standard Linux bridge networking and commercial solutions from Cisco, Nicira, and NEC via a plug-in architecture. Additionally, the release includes significant updates to control Layer 2 networking, IP address management, API quotas, notifications, extension support for Layer 3 forwarding, Secure Network Address Translation (SNAT), and floating IPs.
The second full release of OpenStack Dashboard brings usability improvements in launching Compute instances, working Object Storage resources, and managing OpenStack projects and users. Other feature advances include support for public and private image uploads and management of advanced networks. End users will appreciate better cross-browser support, timezone support, dynamic quota displays, improved error handling, and performance improvements.
The second full release of OpenStack Identity brings improved support for Public Key Infrastructure (PKI) authentication and improved integration and management across OpenStack services.
There were major advancements in usability and functionality to the Image Service, including a new API, a new client library, new replication options for increased performance and security improvements reaching from the client to the image storage system.
Thank you to the global team of 300+ developers who delivered the sixth OpenStack release on time and with every critical feature:
