The OpenStack User Survey has been fielded since 2013, and the OpenInfra Foundation does annual analysis (August to August) to identify new users, uncover trends and better understand the architectural choices made by OpenStack users. Due to the customization opportunities, this User Survey is the most detailed of all OpenInfra project user surveys.
Over 300 OpenStack deployments were logged this year, including a significant number of new clouds—in the last 18 months, over 100 new OpenStack clouds have been built, growing the total number of cores under OpenStack management to more than 25,000,000. This increase in cores is also supported by some known users witnessing incredible growth—including Walmart who has now exceeded 1 million cores in production.
Walmart is not alone: there are now seven organizations in the User Survey running over 1 million cores in production, including China Mobile, Verizon Media, LINE, Workday and a few additional organizations who would like to remain anonymous.
This growth was not limited to the largest deployments. Several deployments saw over 100% growth in their OpenStack footprints compared to 2020 while still remaining below 10,000 cores.
Here is a full breakdown of logged OpenStack deployment sizes:
Of the organizations who completed the 2021 survey, 79% are in production, 13% are under development and 8% are in the proof of concept stage.
When looking at the release of the deployment, the majority of organizations are running within the last seven releases:
Among the environments running OpenStack, several individual components saw considerable growth in production clouds:
Kolla: 28% up from 17% in 2020
Magnum: 17% up from 10% in 2020
Over 200 deployments were recorded as interacting with another cloud. When asked which clouds their deployment interacted with, 53% of the respondents selected AWS, 40% selected Azure, 30% selected GCE, 34% selected another OpenStack private cloud, 13% selected an OpenStack public cloud and an additional 8% said other. Despite running multiple clouds, most respondents indicated that openstack powers more of their cloud infrastructure than any other platform.
Regarding other tools within the deployments, the most popular choices include:
Organizations completing the 2021 OpenStack Deployment User Survey include CERN, the German Climate Computing Centre, Hospital Clínic de Barcelona, NASA Goddard Space Flight Center, Societe Generale, Vingroup and Workday. Hundreds of additional organizations have requested to remain confidential.
The 2021 NPS score for OpenStack is 36. Some of the reasons provided included:

Since the launch of the Airship User Survey in May 2020, ten organizations have completed it, spanning industries such as telecommunications, Information Technology, Academic / Research, Government / Defense, and Retail / Ecommerce. Of those organizations, half are running Airship in production, while 30% are actively evaluating Airship and 20% are considering it.
When asked what kind of workloads respondents were interested in, 10% selected Kubernetes workloads only, 20% selected VM workloads on OpenStack-helm only and the remaining 70% selected both.
Organizations who completed the Airship User Survey include ServerAnt, Havelsan and SK Telecom. Additional organizations have requested to remain anonymous.
Here are a few reasons respondents shared when asked which features of Airship affected their choice to use/consider/evaluate Airship:
The NPS score of the Airship project is 50. Some of the reasons provided included:
The Kata Containers User Survey opened in April 2020 and has recently undergone an update by the Architecture Committee.
Since April 2020, 26 organizations have completed the survey, spanning industries such as:
Among those organizations, 58% are evaluating Kata Containers, 19% are considering using Kata Containers and 15% are running Kata Containers in production.
When asked which orchestrator an organization is using, 62% indicated Kubernetes, while 19% said Docker. The additional 24% did not specify.
While 57% of organizations said their workloads are a mixture of both short and long-running workloads, 24% said theirs are long-running (greater than 1 minutes) and 10% indicated theirs were short-lived (less than one minute).
Here are some responses from what respondents like most about Kata Containers, besides “free” and “open”:
Organizations who completed the Kata Containers User Survey include Baidu, Huawei, Qualogy, Federal University of Technology Minna Nigeria, AstroKube, Adobe Advertising Cloud and IBM Research. Additional organizations have requested to remain anonymous.
The Kata Containers User Survey has recently been updated by the community to learn more about operators’ architectural decisions around Kata Containers and how satisfied they are with the project and community.
The StarlingX User Survey launched in March 2019 and has received over 30 responses. Of those organizations, 34% are interested in StarlingX, 46% are running a proof of concept, 15% are testing, and 4% are running StarlingX in production.
The edge use cases that organizations are turning to StarlingX for are:
Among the organizations selecting ‘Other,’ use cases included research in edge computing, uCPE, IoT nodes and gateways, and edge compute for very small clusters.
Organizations who have completed the StarlingX User Survey have requested to remain anonymous.
The Zuul User Survey began collecting responses in March 2020 and has received almost 30 organization submissions to date.
Of these organizations, a whopping 69% are running Zuul in production, 17% are evaluating Zuul, and 14% are considering using Zuul.
The amount of jobs run per day varies by organization. 69% of organizations run less than 100 jobs per day, 12% run 100-1,000 jobs per day, 8% run 1,000-10,000 jobs per day, 8% run 10,000 - 100,000 jobs per day and 4% run more than 100,000 jobs per day.
Organizations who completed the Zuul User Survey include BMW, Volvo, NTT, Wazo-Platform, Good Money, leboncoin, T-Systems, 99Cloud, CESNET, OpenDev, Red Hat and Just Eat. Additional organizations have requested to remain anonymous.
