OpenNebula shares key findings from its 2023 architecture survey

The latest architecture survey of OpenNebula usage provides further insight into its customers’ continued adoption of its cloud computing platform.

Commercial industries constitute a significant part of the OpenNebula user base, with a combined usage surpassing 85%.

OpenNebula’s role as a “replacement solution” for other cloud solutions is significant, with over 50% of users choosing it as their preferred alternative. Interestingly, 41% of these users opted to replace VMware with OpenNebula.

Integration with public cloud resource providers is a common practice among OpenNebula users. According to the survey, AWS remains a popular choice, but Microsoft Azure is the most preferred provider.

OpenNebula usage, in terms of zones and node count, appears steady, with no notable change in distribution. The survey also indicates an emerging trend towards deploying Edge Cloud, with nearly 30% of respondents signaling their intention soon.

A shift in the preferred operating system was noted, with a move away from CentOS following Red Hat’s announcement of its end of life. This has led to rising preferences for AlmaLinux and Rocky Linux, with OpenNebula recently introducing enterprise support. Debian-based systems, however, continue to be more popular among OpenNebula users, accounting for 86% of the total user base.

The survey notes a trend of OpenNebula users increasingly adopting KVM as their preferred choice. There is also a slight decline in VMware usage compared to the previous study. LXD and LXC are also less popular alternatives among users. Shared Datastores continues to lead among the available storage options, followed by Ceph storage.

Regarding networking configurations, Bridged networks and VLANs remain the most popular choices for OpenNebula users. MariaDB emerges as the top database of choice, although MySQL also has a sturdy user base. Monitoring preferences have changed slightly with a rise in Prometheus usage following its recent integration. Ansible remains the preferred configuration management tool, and Terraform is the top choice for infrastructure provisioning.

Kubernetes maintains its popularity among organizations, and SUSE Rancher follows closely behind in the container category. Prometheus and Grafana, recently included in the Enterprise Edition of the OpenNebula software, have sparked significant interest, along with the Restic Backup system. API usage remains steady, with Python bindings being the most popular choice.

This is the sixth architectural survey of OpenNebula, with data collected throughout February 2023. The insights demonstrate how the user community utilizes OpenNebula and highlights their evolving requirements.
