Request for Scientific Resources on OpenStack Cost Efficiency Compared to Public Cloud Providers
by HAMMOUMI TARIK 27 Oct '24

27 Oct '24

Dear OpenStack Community, I am currently working on a case study as part of my software engineering course, where I aim to examine the cost efficiency of OpenStack as a private infrastructure solution in comparison to public cloud services such as AWS, Google Cloud, and Azure. My goal is to determine whether OpenStack can be more cost-effective in the long term, particularly for organizations that rely heavily on sustained workloads. In my initial research, I encountered challenges finding scientific studies or published articles that provide a clear, data-driven comparison between the Total Cost of Ownership (TCO) of OpenStack and that of leading public cloud providers. During a recent discussion with my professor, they emphasized the importance of using concrete, peer-reviewed sources and precise financial comparisons to validate claims about cost savings or trade-offs between owning physical resources and cloud-based infrastructure. I would appreciate it if anyone could point me to peer-reviewed research, published case studies, or white papers that analyze OpenStack’s TCO, especially in comparison to major public cloud providers. Insights on maintenance and operational costs for OpenStack in practical, high-utilization scenarios would be particularly helpful. Thank you in advance for any assistance or direction on reliable resources. I look forward to contributing to this ongoing discussion and hopefully sharing insights from my findings with the community. Best regards, Tarik HAMMOUMI (https://itstarik.tech)

Hey Folks, I'm having some trouble getting barbican to generate and/or store keys in our hashicorp vault in our charmed openstack environment. I have issues with both TPM and SSL related keys. I get extremely generic errors back that I can't seem to figure out how to troubleshoot: 'Traceback (most recent call last):\n File "/usr/lib/python3/dist- packages/nova/conductor/manager.py", line 688, in build_instances\n scheduler_utils.populate_retry(\n File "/usr/lib/python3/dist- packages/nova/scheduler/utils.py", line 998, in populate_retry\n raise exception.MaxRetriesExceeded(reason=msg)\nnova.exception.MaxRetriesExce eded: Exceeded maximum number of retries.

Last exception: Key manager error: Internal Server Error: Secret creation failure seen - please contact site administrator.\n' I'm using barbican 14.0.2 in yoga/stable ... anyone have an ideas how to troubleshoot this? -- Andy Speagle

[cloudkitty] 2025.01 PTG summary
by Rafael Weingärtner 23 Oct '24

23 Oct '24

Dear all, The CloudKitty project had a great PTG meeting [1]. Thanks to the OpenInfra Foundation for holding it. Also, thanks to all who have dedicated precious time to attend. We started the meeting by revisiting the latest release and discussing the review format we have adopted in the past years. Looking at the result of our process, we decided to maintain it, as it seems to bring results, and concentrate our efforts on getting CloudKitty better and evolving over time. Furthermore, as the current CloudKitty team is a bit small, we have decided to focus on the following topics for the next cycle. - State of Elasticsearch - We want to make sure the CloudKitty CI tests Elasticsearch v8, driver was last tested on v6/7. - OpenSearch/Elasticsearch datastreams -- It looks like this feature is present in both OpenSearch and Elasticsearch. Therefore, we will make an effort to concentrate on these two drivers, instead of replicating their codebase, and separate between them just the differences. - Epoxy (2025.1) supported runtimes -- we will drop the unsupported Python releases/versions. - oslo.policy RBAC new defaults -- We will need to address these new supports in the upcoming release. - Horizon dashboard improvements -- Borrow ideas from Catnip? https://github.com/ObjectifLibre/catnip, and maybe discuss with other agents from the community. In summary that is the outcome of our small, but efficient PTG meeting. Let's keep improving and making CloudKitty better. If I missed something, please do not hesitate to reply back. Also, if somebody needs any help, you can always ping me :) See you guys. Have a nice week! [1] https://etherpad.opendev.org/p/oct2024-ptg-cloudkitty -- Rafael Weingärtner

[ironic] Core team split into reviewers/approvers
by Jay Faulkner 23 Oct '24

23 Oct '24

OpenStack & Ironic community, Ironic has not added a core reviewer in years. We've had new contributors during this time, but none who has, as yet, risen to the level of being given core review access -- which reflects how steep the learning/responsibility curve is to being a core on an OpenStack project. I'd like to propose, on behalf of many Ironic cores and our PTL Riccardo, a new core review structure for Ironic projects. The goal being to provide an on-ramp for newer cores into the community. The existing ironic-core group will be removed and replaced with two new groups: - ironic-reviewers will contain contributors permitted to perform core reviews (+2/-2) against patches in ironic projects. This group will be initially populated with two new code reviewers (should they accept), CID and cardoe. - ironic-approvers will contain contributors permitted to both perform core reviews and workflow (+A) patchsets. This group will be initially populated with the existing membership of ironic-core. I hope that by providing a middle point on the route to being an approver, we'll be able to extend trust to new contributors more quickly and give them incentive to code review more often -- since their reviews will be able to have a positive impact on landing code more quickly. I've proposed a change here: https://review.opendev.org/c/openstack/project-config/+/931991which makes the first step in adjusting ACLs to split the groups. I've also as part of this change unified more ironic-related projects under the ironic core review banner after auditing those core groups and seeing some inactive contributors in them. Ironic cores have already discussed this privately, and we have a lazy consensus to perform this change. This email serves as both notice to the larger community and as a formal way to gain consensus. If there are any questions or concerns please let us know. Thanks, Jay Faulkner
