+# KubeVirt 2020 Annual Review
+
+## Background
+
+KubeVirt is a virtualization management add-on for Kubernetes. It allows a user
+to run virtual machines on Kubernetes just like pods. Because KubeVirt is
+integrating with the Kubernetes API and resource model, the same set of tools
+can be used to manage and monitor virtual machines.
+
+KubeVirt joined the CNCF as a sandbox project in September 2019 (ref.
+[KubeVirt sandbox submission](https://github.com/cncf/toc/blob/master/proposals/sandbox/kubevirt.adoc)).
+
+## Develoment metrics
+
+Here are a few highligths from the project's [devstats
+page](https://kubevirt.devstats.cncf.io/), looking at the 1 year period after
+sandbox inclusion (Sept 2019 - Sept 2020):
+
+ - This year we welcomed [70 new contributors](https://kubevirt.devstats.cncf.io/d/52/new-contributors-table?orgId=1&from=1567288800000&to=1598997599000) across our repositories.
+ - The number of [active contributors](https://kubevirt.devstats.cncf.io/d/7/companies-contributing-in-repository-groups?orgId=1&from=1567288800000&to=1598997599000&var-period=m&var-repogroup_name=All)
+ increased to 152, up from 112.
+ - These active contributors come from 27 different companies, up from 16.
+ - The
+ [activity](https://kubevirt.devstats.cncf.io/d/1/activity-repository-groups?orgId=1&from=1567288800000&to=1598997599000&var-period=d7&var-repogroups=All)
+ across repositories shows a clear steady increase.
+
+### Maintainers
+
+The KubeVirt project includes several components and there are various
+repositories in the KubeVirt github org, each with its own set of core
+mainainers:
+
+ - The main [kubevirt](https://github.com/kubevirt/kubevirt) repository
+ currently has 13 core maintainers, listed in its
+ [OWNERS_ALIASES](https://github.com/kubevirt/kubevirt/blob/master/OWNERS_ALIASES)
+ file. At this point, all of them are Red Hat employees.
+ - Other repositories for components of the KubeVirt project have their own list
+ of maintainers. Usually these maintainers do not overlap with the ones listed
+ above. For example, the maintainers for the second and third repositories in
+ terms of activity as per the dev stats are:
+ - [Hyperconverged Cluster Operator](https://github.com/kubevirt/hyperconverged-cluster-operator/blob/master/OWNERS_ALIASES) has 8 approvers.
+ - [Containerized Data Importer](https://github.com/kubevirt/containerized-data-importer/blob/master/OWNERS_ALIASES) has 3 approvers.
+
+
+### Other metrics
+
+Besides contributor metrics, the following numbers also highlight how the
+project has gathered more interest since it joined the CNCF sandbox last year:
+
+ - [~2200 github stars](https://github.com/kubevirt/kubevirt/stargazers), up from 1348 at the time of sandbox inclusion last year.
+ - Kubernetes Slack channel members:
+ - The general [#virtualization](https://kubernetes.slack.com/archives/C8ED7RKFE) channel now has 700+ members (up from 290 last year).
+ - A new channel was created this year, focused on development:
+ [#kubevirt-dev](https://kubernetes.slack.com/archives/C0163DT0R8X)
+ currently has ~160 members.
+ - the traffic on the [kubevirt.io website](https://kubevirt.io) approximately
+ doubled in page views and unique visitors.
+
+## Adoption
+
+We have seen the increased interest mentioned in the previous section through
+the various community communication channels, with a growth of breadth and depth
+of participation from users and contributors.
+
+An informal usage poll was conducted recently through
+[twitter](https://twitter.com/kubevirt/status/1319251272772603904) and
+[Slack](https://kubernetes.slack.com/archives/C8ED7RKFE/p1603368795347300). Of
+the ~100 respondents, a majority expressed that they are _evaluating_ KubeVirt
+at the moment. About 20% metioned a _development or pre-production_ use case,
+and around 5% had _production_ workloads.
+
+As highlighted by devstats we have also seen an increase in companies
+contributing to KubeVirt. Related to this, the project also has a growing number
+of technology vendors who include KubeVirt technology in their offerings:
+
+ - [OpenShift Virtualizaton](https://www.openshift.com/learn/topics/virtualization/)
+ - [Gardener](https://gardener.cloud/blog/2020-10/00/)
+ - [Kubermatic Virtualization](https://www.kubermatic.com/products/kubevirt/)
+ - [Rancher's harvester](https://github.com/rancher/harvester/blob/766abd06561b059c1af623aacc4e505db471ceee/deploy/charts/harvester/README.md)
+ - [Google Anthos](https://youtu.be/RE0A3kHT3LA?t=126)
+
+## Project goals
+
+### Performance against last year's goals
+
+Since our inclusion in the CNCF sandbox our focus has been to be a welcoming
+community while working to add more core features that are to be expected from a
+virtualization management project.
+
+We believe we have achieved good and consistent results through a regular,
+predictable cadence of [releases](https://github.com/kubevirt/kubevirt/releases)
+([once a month](https://kubevirt.io/blogs/releases.html)) that brought many new
+features and improvements.
+
+### Current goals
+
+Our priorities for this next year are:
+
+ - Define and release version 1.0. Work to scope this milestone release already
+ started.
+
+ - Improve the communication with end users.
+
+ - Improve the developer experience by making PR contributions easier.
+
+These goals translate to multiple specific work items, including:
+
+ - A documentation revamp, working towards a more use case / workflow oriented
+ approach and fully comprehensive documentation. This is one of the
+ requirements for version 1.0.
+
+ - CI improvements for an even better development environment
+
+ - A KubeVirt event that includes a contributor oriented working space as
+ well as user oriented content.
+
+## CNCF membership
+
+ - How can the CNCF help you achieve your upcoming goals?
+
+ - The CNCF has helped the project significantly this year, through presence
+ in the maintainer tracks in events and webinars as well as infrastructure
+ and support services, and guidance opportunities like the technical writers
+ office hours. We would like all these types of project support to continue.
+
+ - Do you think that your project meets the [criteria for
+ incubation](https://github.com/cncf/toc/blob/master/process/graduation_criteria.adoc#incubating-stage)?
+
+ - We believe that the project is in a healthy growing status in both user
+ adoption and contributors. We are working to properly document existing
+ production usage and we expect that the contributor growth will also imply
+ a diverse group of maintainers.
+
+ - With the current status and the existing plans we believe that we are on a
+ good track towards incubating stage.
