2.10. Technology Previews

This section outlines features that are in technology preview in Red Hat OpenStack Platform 9.

Note

For more information on the support scope for features marked as technology previews, see Technology Preview Features Support Scope.

2.10.1. New Technology Previews

The following new features are provided as technology previews:
Google Cloud storage backup driver (Block Storage)
The Block Storage service can now be configured to use Google Cloud Storage for storing volume backups. This feature presents an alternative to the costly maintenance of a secondary cloud simply for disaster recovery.
Shared File System Service
The Shared File System service (manila) is still included as a Technology Preview. With this release, you can test the service with the following drivers:
  • NetApp (manila.share.drivers.netapp.common.NetAppDriver)
  • CephFS native driver (manila.share.drivers.cephfs.cephfs_native.CephFSNativeDriver)
The new CephFS native driver allows the Shared File System service to export shared CephFS file systems to guests through the Ceph network protocol. Instances must have a Ceph client installed to mount the file system. The CephFS file system is included in Red Hat Ceph Storage 2.0 as a technology preview as well.
At-Rest Encryption (Object Storage)
Objects can now be stored encrypted form (using AES in CTR mode with 256-bit keys). This provides options for protecting objects and maintaining security compliance in Object Storage clusters.
OpenDaylight Beryllium SR2
OpenDaylight Beryllium SR2 is now available on this release as a Technology Preview.
Red Hat SSO
This release includes a version of the keycloak-httpd-client-install package. This package provides a command-line tool that helps configure the Apache mod_auth_mellon SAML Service Provider as a client of the Keycloak SAML IdP.

2.10.2. Previously Released Technology Previews

The following features remain as technology previews:
Cells
OpenStack Compute includes the concept of Cells, provided by the nova-cells package, for dividing computing resources. For more information about Cells, see Schedule Hosts and Cells.
Alternatively, Red Hat OpenStack Platform also provides fully supported methods for dividing compute resources in Red Hat OpenStack Platform; namely, Regions, Availability Zones, and Host Aggregates. For more information, see Manage Host Aggregates.
Distributed Virtual Routing
Distributed Virtual Routing (DVR) allows you to place L3 Routers directly on Compute nodes. As a result, instance traffic is directed between the Compute nodes (East-West) without first requiring routing through a Network node. Instances without floating IP addresses still route SNAT traffic through the Network node.
DNS-as-a-Service (DNSaaS)
Red Hat OpenStack Platform 8 includes a Technology Preview of DNS-as-a-Service (DNSaaS), also known as Designate. DNSaaS includes a REST API for domain and record management, is multi-tenanted, and integrates with OpenStack Identity Service (keystone) for authentication. DNSaaS includes a framework for integration with Compute (nova) and OpenStack Networking (neutron) notifications, allowing auto-generated DNS records. In addition, DNSaaS includes integration support for PowerDNS and Bind9.
Erasure Coding (EC)
The Object Storage service includes an EC storage policy type for devices with massive amounts of data that are infrequently accessed. The EC storage policy uses its own ring and configurable set of parameters designed to maintain data availability while reducing cost and storage requirements (by requiring about half of the capacity of triple-replication). Because EC requires more CPU and network resources, implementing EC as a policy allows you to isolate all the storage devices associated with your cluster's EC capability.
File Share Service
The OpenStack File Share Service provides a seamless and easy way to provision and manage shared file systems in OpenStack. These shared file systems can then be used (mounted) securely to instances. The File Share Service also allows for robust administration of provisioned shares, providing the means to set quotas, configure access, create snapshots, and perform other useful admin tasks.
Firewall-as-a-Service (FWaaS)
The Firewall-as-a-Service plug-in adds perimeter firewall management to OpenStack Networking (neutron). FWaaS uses iptables to apply firewall policy to all virtual routers within a project, and supports one firewall policy and logical firewall instance per project. FWaaS operates at the perimeter by filtering traffic at the OpenStack Networking (neutron) router. This distinguishes it from security groups, which operate at the instance level.
Operational Tools
Operational Tools are logging and monitoring tools which facilitate troubleshooting. With a centralized, easy-to-use analytics and search dashboard, troubleshooting is simplified, and features such as service availability checking, threshold alarm management, and collecting and presenting data using graphs are available.
VPN-as-a-Service (VPNaaS)
VPN-as-a-Service allows you to create and manage VPN connections in OpenStack.
Benchmarking Service

Rally is a benchmarking tool that automates and unifies multi-node OpenStack deployment, cloud verification, benchmarking and profiling. It can be used as a basic tool for an OpenStack CI/CD system that would continuously improve its SLA, performance and stability. It consists of the following core components:
  1. Server Providers - provide a unified interface for interaction with different virtualization technologies (LXS, Virsh etc.) and cloud suppliers. It does so via ssh access and in one L3 network
  2. Deploy Engines - deploy an OpenStack distribution before any benchmarking procedures take place, using servers retrieved from Server Providers
  3. Verification - runs specific set of tests against the deployed cloud to check that it works correctly, collects results & presents them in human readable form
  4. Benchmark Engine - allows to write parameterized benchmark scenarios & run them against the cloud.
DPDK-Accelerated Open vSwitch
The Data Plane Development Kit (DPDK) consists of a set of libraries and user-space drivers for fast packet processing, enabling applications to perform their own packet processing directly to/from the NIC, delivering up to wire speed performance for certain use cases. In addition, OVS+DPDK significantly improves the performance of Open vSwitch while maintaining its core functionality. It enables the packet switching from the host’s physical NIC to the application in the guest instance (and between guest instances) to be handled almost entirely in user-space.
In this release, the OpenStack Networking (neutron) OVS plugin was updated to support OVS+DPDK back end configuration. OpenStack projects can now use the neutron API to provision networks, subnets and other networking constructs, while using OVS+DPDK to gain improved network performance for instances.
OpenDaylight Integration
Red Hat OpenStack Platform 8 now includes a technology preview of integration with the OpenDaylight SDN controller. OpenDaylight is a flexible, modular, and open SDN platform that supports many different applications. The OpenDaylight distribution included with Red Hat OpenStack Platform 8 is limited to the modules required to support OpenStack deployments using OVSDB NetVirt, and is based on the upstream Beryllium version. The following packages provide the Technology Preview: opendaylight, networking-odl
Real Time KVM Integration

Integration of real time KVM with the Compute service further enhances the vCPU scheduling guarantees that CPU pinning provides by reducing the impact of CPU latency resulting from causes such as kernel tasks running on host CPUs. This functionality is crucial to workloads such as network functions virtualization (NFV), where reducing CPU latency is highly important.
Containerized Compute Nodes

The Red Hat OpenStack Platform director has the ability to integrate services from OpenStack's containerization project (kolla) into the Overcloud's Compute nodes. This includes creating Compute nodes that use Red Hat Enterprise Linux Atomic Host as a base operating system and individual containers to run different OpenStack services.
