Mirantis OpenStack for K8s 21.4 Delivers Greater Scalability and Enhanced Connectivity
- September 09, 2021
We are pleased to announce the availability of Mirantis OpenStack for K8s, version 21.4. This release includes a number of important enhancements that enable our customers to support a broader scale of deployment, extend their private clouds over public networks and ensure they have a path of robust support with OpenStack Victoria LTS.
Key new features include:
This use case has been verified for core OpenStack services with OvS and non-DVR Neutron configuration on a dedicated hardware scale lab.
Lastly, we have also enhanced our documentation to provide you with a better product experience:
If you'd like to test drive Mirantis OpenStack for K8s, get started with a free trial.
Key new features include:
Support for large deployments based on Open vSwitch
We have added support for large-scale deployments numbering up to 200 nodes out of the box, enabling customers to deploy Mirantis OpenStack into larger-scale environments as their business demands continue to grow.This use case has been verified for core OpenStack services with OvS and non-DVR Neutron configuration on a dedicated hardware scale lab.
Compact control plan for small Open vSwitch-based Clouds
We are not only adding the ability to scale to larger deployments, but we have also introduced the ability to address small clouds with the introduction of our compact control plane. This enhancement allows the ability to run all control plane components, K8s masters, OpenStack and StackLight on just 3x servers, which would be useful not only for Proof of Concept applications but also for distributed Edge clouds.BGP-VPN support for Open vSwitch-based clouds
Mirantis OpenStack for K8s 21.4 enables users to host distributed private clouds over a public network, taking advantage of newly supported BGP-VPN services. These services allow for the connection of OpenStack Virtual Private Networks with external VPN sites through either BGP/MPLS IP VPNs or E-VPN.Default Policy override for core OpenStack Services
Mirantis OpenStack for K8s 21.4 adds a mechanism to define additional policy rules for the core OpenStack services through the OpenStackDeployment Custom Resource. This enhancement, when combined with OpenStack domain mechanisms, enables the ability to build “sandboxes” for multi-tenant operation where individual “tenants” within an OpenStack deployment can have their own isolated spaces without risk of impacting other “tenants”.Automatic evacuation of VMs from failed hosts
Based on OpenStack Masakari, the host monitor is deployed by default with Instances High Availability Service for OpenStack to provide automatic instance evacuation from failed instances, providing an increased level of resiliency for your deployment.Cinder backend for Glance - Generic iSCSI
For customers who rely on external storage appliances to implement block storage, in the absence of Ceph, Glance would still require a place to store VM images. The newly supported Cinder backend for Glance allows the presentation of Cinder volumes as Glance images and snapshots, using the same storage appliance for all the persistent data in the cloud.OpenStack Victoria LTS
OpenStack Victoria with OvS now has LTS status, and full support is provided for OpenStack Victoria with Tungsten Fabric 5.1 for both greenfield and new deployments. This LTS support ensures that our customers have a solid, supported base for their deployments.Lastly, we have also enhanced our documentation to provide you with a better product experience:
- API Reference - comprehensive description for OpenStack LCM API (OpenStackDeployment, TFOperator CRs), automatically updated from code with every release. The source of truth about the language operators need to talk to MOS.
- User Guide - Intended to assist you in the deployment and usage of Mirantis OpenStack - this guide is focused on both key use cases or those that are poorly covered in the upstream documentation. We look at this is as “the manual that needs to come with the manual” to supplement the upstream documentation.
