China is the third largest contributor to CNCF projects (in terms of contributors and committers) after the U.S. and Germany.
KubeCon + CloudNativeCon has expanded from its start with 500 attendees in 2015 to become one of the largest and most successful open source conferences ever. The KubeCon + CloudNativeCon North America event in Seattle , held December 10-13, 2018, was our biggest yet and was sold out several weeks ahead of time with 8,000 attendees.
KubeCon + CloudNativeCon co-chair Liz Rice of Aqua Security gave a CNCF community update, alongside a number of our project maintainers, including a Helm update from Michelle Noorali of Microsoft and an Envoy update from Matt Klein of Lyft.
KubeCon + CloudNativeCon Seattle attendance increased 90% from last year’s KubeCon + CloudNativeCon North America event in Austin. And while the attendee numbers grew, the great developer conference experience remained the same.
KubeCon + CloudNativeCon co-chair Janet Kuo of Google explained that Kubernetes being boring was a good thing. As co-chair Liz Rice of Aqua Security said: “CNCF is not here to throw glitzy events, but to help us coordinate as a community and ensure we have proper governance in place.” Kelsey Hightower gave a shout out to the amazing real women of Hidden Figures, his mom, and the Queen of Motown, Diana Ross, in his serverless keynote.
The co-chairs select a program committee of around 80 experts, including project maintainers, active community members, and highly-rated presenters from past events, to review the CFP submissions. The keynote speakers are selected by the conference co-chairs from highly-rated CFP submissions, or in rare cases, by invitation from the co-chairs. KubeCon + CloudNativeCon Seattle included 318 sessions: CFP tracks sessions, lightning talks, BoFs, tutorials, and maintainer track sessions, which were offered in ~10 rooms as well as ~90 maintainer sessions spread across ~5 rooms.
It is unprecedented to get every cloud company, enterprise software provider, and startup in the industry to support a conformance program. CNCF has achieved this with the Certified Kubernetes Conformance Program , which enables any Kubernetes implementation to demonstrate that it is conformant and interoperable. Nearly all of the world’s leading software vendors and cloud computing providers have Certified Kubernetes offerings.
It is an extraordinary accomplishment that there are no forks in our industry, which speaks to the commitment that companies of all sizes have made to be good partners in the community. CNCF has certified offerings from 76 vendors.
2018 was a very busy year for CNCF projects, including the graduations of Kubernetes, Prometheus, and Envoy. 7 CNCF projects were the winners out of the 13 awards in cloud computing in InfoWorld’s 2018 Best of Open Source Software ( BOSSIE )
We are pleased to share the results from the maintainer surveys we do twice a year:
The overall satisfaction with CNCF increased in 2018 and reflected a 100% response rate across projects. For the first time, we asked if maintainers would recommend CNCF to other projects. Responses were positive with a score of 4.22/5.
CNCF projects have a maturity level of sandbox, incubating, or graduated. CNCF uses these maturity levels to signal to enterprises which projects they should adopt. Graduated projects are suitable for the vast majority of all enterprises. Incubating projects are suitable for early adopters, and sandbox projects are for innovators. Projects increase their maturity level by demonstrating to the TOC that they have adoption, healthy rate of changes, and committers from multiple organizations as well as adopting the CNCF Code of Conduct and earning the Core Infrastructure Initiative Best Practices Badge . Full details are listed in Graduation Criteria v1.1 .
2018 highlights include the addition of 16 new projects by the CNCF TOC , listed in order of date accepted:
Many milestone releases demonstrated steady forward progress for each of these projects.
CNCF provided a variety of services to our projects to help make them more successful.
CNCF funded and orchestrated security audits for:
“In spite of eight security-relevant findings, the team responsible for this assessment of the Envoy compound can attest to the overall good state of security matters at the tested project. After spending twenty days on the Envoy test target in February 2018, the penetration testers concluded that the software was appropriately built and deployed. Similarly, positive impression concerned the Envoy code, which the auditors found to be well-written.”
To improve access to the above type of activities and services for projects, the CNCF Service Desk serves as a single access point for all CNCF services. If you’re a CNCF project maintainer, all you have to do is visit https://servicedesk.cncf.io or email firstname.lastname@example.org to request support.
Education, inclusion, and collaboration are vital to the future of the cloud native ecosystem.
Part of supporting the continued development of this amazing community is making sure that everyone who wants to participate feels welcome to do so regardless of gender, gender identity, sexual orientation, disability, race, ethnicity, age, religion, or economic status. While having more female speakers at KubeCon + CloudNativeCon Seattle was an important step forward, there were a number of other activities that brought together the diversity of the cloud native community: speed networking and mentoring, the diversity lunch, sessions on building a community through Meetups, and KubeCon + CloudNativeCon diversity scholarships.
CNCF’s diversity program offered scholarships to 147 recipients from traditionally underrepresented and/or marginalized groups to attend KubeCon + CloudNativeCon Seattle . These scholarships cover both the cost of the ticket as well as airfare and lodging. The $300,000 for Seattle, the largest investment made by a conference in diversity, was mainly contributed by CNCF, along with donations from Aspen Mesh, MongoDB, Twistlock, Two Sigma, and VMware. Including Seattle, CNCF has to date offered more than 485 diversity scholarships to attend KubeCon + CloudNativeCon events.
CNCF collaborated with the Kubernetes mentoring program to offer networking opportunities for mentees at KubeCon + CloudNativeCon . 66 mentors and 180 mentees participated in this program in Seattle.
For the third year in a row, the CNCF Community Awards, sponsored by VMware, highlighted the most active ambassador and top contributor across all CNCF projects.
It is essential not to overlook the individuals who give countless hours of their time to complete often mundane tasks, so CNCF created the Chop Wood/Carry Water awards. It was a proud moment for the cloud native community as CNCF recognized the tireless efforts of 14 individuals for their outstanding contributions from the past year: April Kyle Nassi, Babak “Bobby” Salamat, Christoph Blecker, Davanum Srinivas, Dianne Mueller, Jorge Castro, Kris Nova, Nikhita Raghunath, Paris Pittman, Reinhard Nagele, Richard Hartmann, Stephen Augustus, Tim Pepper, and Zach Arnold.
CNCF supported more than 160 meetup groups in 38 countries, which have hosted more than 1,600 events and include more than 80,000 members. In 2018, we experienced a 60% increase in CNCF meetup members.
The CNCF community spans the world through our contributors, members, meetups, and ambassadors. We boast more than 45,000 contributors to our CNCF projects, and we have 65 CNCF Ambassadors worldwide educating the world on cloud native technologies and best practices.
We accepted 47 new CNCF ambassadors and provided financial support for ambassador-run meetups in 2018. Our vibrant community of successful ambassadors is comprised of developers, bloggers, influencers, and evangelists already engaged with a CNCF project in some way including contributing to development, online groups, and community events. We are excited to have this worldwide group of people with diverse interests, experiences, and technical backgrounds help drive local and global cloud native communities. Please check out the video interviews with several of our CNCF ambassadors or read about them.
In 2016, Deis (now part of Microsoft) Platform Architect Matt Butcher was looking for a way to explain Kubernetes to technical and non-technical people alike. Inspired by his daughter’s prolific stuffed animal collection, he came up with the idea of The Illustrated Children’s Guide to Kubernetes . Thus Phippy, the yellow giraffe and PHP application, along with her friends, were born.
On the keynote stage during Day 1 of the KubeCon + CloudNativeCon Seattle conference, Matt and co-author Karen Chu announced Microsoft’s donation of Phippy to CNCF and presented the official sequel in their live reading of Phippy Goes to the Zoo: A Kubernetes Story . As part of Microsoft’s donation of both books and the characters, CNCF has licensed all of this material under the Creative Commons Attribution License (CC-BY), is available to remix, transform, and build upon the material for any purpose, even commercially. See phippy.io for more information.
CNCF developed DevStats starting in mid-2017 in response to requests from the Kubernetes Steering Committee and SIG-Contributor Experience to provide insight into how Kubernetes was dealing with nearly unprecedented growth. (It’s the second-largest community in open source, behind only Linux.) The tool, which is open source, downloads several terabytes of data representing every public GitHub action of the last 5 years, throws out nearly all of it except for the ~100 repos of CNCF-hosted projects, processes the data and stores it in a Postgres database, and then displays it using Grafana dashboards. DevStats now covers all CNCF-hosted projects and downloads updated data every hour. More recently, we have been iterating on several versions of a project status dashboard based on feedback from the TOC and project maintainers.
DevStats is one of the most powerful visualization tools available for understanding contributions to open source software. It is also a testament to the power of open source development, as CNCF developer Lukasz Gryglicki remains very responsive to suggestions and pull requests that provide additional insights into the development of CNCF’s hosted projects.
The CNCF Cloud Native Landscape is intended as a map through the previously uncharted terrain of cloud native technologies. The landscape started in November 2016 as a static image of fewer than 100 projects and products. It has grown through the power of collaborative editing to track more than 600 items and now includes a serverless landscape. The project has more than 4,000 stars on GitHub.
In March 2018, CNCF released the Cloud Native Landscape 2.0, an interactive version that allows viewers to filter, obtain detailed information on a specific project or technology, and easily share via stateful URLs. The interactive landscape is open source with the data stored in a yaml file. Every night, a server downloads updated GitHub data, financing information from Crunchbase, market cap data from Yahoo Finance, and CII Best Practices Badge information.
In response to feedback that the landscape presents an overwhelming number of options, CNCF released the Cloud Native Trail Map , which provides an overview for enterprises starting their cloud native journey. While there are innumerable routes for deploying a cloud native application, CNCF projects represent a particularly well-traveled, tested, and trusted path.
No matter the exact path each organization chooses to travel on its way to becoming cloud native, the goal of these new interactive and introductory guides is to help a company progress on its cloud native journey.
We are excited to share the CNCF Style Guide with the community. We published the style guide last year to help establish a consistent format for writing about cloud native technologies.
CNCF also maintains a repository of project logos in standard formats, shapes, and colors. There are 3 formats (PNG/SVG/AI), 3 layouts – horizontal (also known as landscape format), stacked (which is closer to square), and icon (which does not include the name and is square) – and 3 versions (color/black/white), which results in 27 versions of each logo.
The Certified Kubernetes software conformance program relies on the open source conformance tests included in each version of Kubernetes. However, these tests are not as comprehensive as the community would like, as they don’t yet cover all stable APIs. CNCF has been investing in test development to add conformance tests, particularly for portions of the API that get heavily exercised by different Kubernetes implementations. Philosophically, CNCF generally avoids hiring engineers because we don’t want to compete with our members. We made an exception in this case to try to address some of the technical debt of having features in the stable API without corresponding conformance tests.
In 2018, CNCF negotiated a software development contract with a well-regarded test development company, Globant, to have 2 engineers work full-time on conformance test development. All tests are submitted as PRs and approved through the normal SIG-Testing review process and with approval from SIG-Architecture. Additionally, after consultation with CNCF staff, SIGArchitecture promulgated a new requirement that new features in Kubernetes require conformance tests before becoming part of the stable API . Thus, this test development is intended to focus on paying off the past technical debt rather than an indefinite, ongoing commitment of resources.
APISnoop is being developed by CNCF-funded contractors to help measure the usage of the Kubernetes API by different applications. An initial goal is to provide a useful indicator as to which Kubernetes APIs are used the most and don’t yet have conformance tests. This ensures we are testing APIs that are relevant. The output below is one visualization of how API groups’ endpoints and verbs are used today.
CNCF’s first ever conference in China, KubeCon + CloudNativeCon Shanghai in November 2018, exceeded our expectations for serving as a bridge between open source developers in China and the rest of the world. More than 17% of attendees were from outside China, enabling two-way communication about new development and best practices for cloud native computing.
Among Chinese contributors to CNCF-hosted projects, Huawei and PingCAP led the way with 34,000 and 32,000 contributions, respectively, and are the fifth- and sixth-largest contributors overall. We also now host 3 CNCF projects that were born in China: Dragonfly (Alibaba), Harbor (VMware China), and TiKV (PingCAP).
We’re excited to build on this success by hosting KubeCon + CloudNativeCon + Open Source Summit in Shanghai June 24-26, 2019.
Happy Birthday CNCF!
Quite possibly, no software foundation has ever had a more successful year than CNCF did in 2018. The success of CNCF is directly attributable to the contributions and support of member companies, developer community, and end users. We are very grateful for that.
CNCF is committed to fostering and sustaining an ecosystem of open source, vendor-neutral projects by democratizing state-of-the-art patterns to make technology accessible for everyone.
Through initiatives like conformance test development, documentation improvements, and security audits, we are reinvesting the proceeds from membership and conferences into making the cloud native platform more reliable .
Our core strategy in 2019 is to stay focused on the developer community who are the heart and soul of the cloud native ecosystem. We are eager to assist developers, particularly from end user organizations, progress into new roles like contributor and maintainer.
In 2019, we will also focus on increased engagement with end users to ensure their voices are represented, their feedback is acted upon, and their organizations are set up for successfully adopting cloud native.
Our flagship events KubeCon + CloudNativeCon will continue to bring together the community and create opportunities for collaboration. We expect our three events – Barcelona (May 20-23), Shanghai (June 24-26), and San Diego (November 18-21) – to be the best yet. We will help CNCF projects accelerate to reach critical mass and achieve their maximum potential. We will also continue investing in new markets like China and India that are embracing cloud native and open source technologies at a phenomenal rate. Our first Kubernetes Day event will be in Bengaluru on March 23.
Another major focus of 2019 will be helping expand cloud native technologies to telcos. We will be demonstrating how they can evolve their Virtual Network Functions (VNFs) architectures into Cloud Native Network Functions (CNFs) running on Kubernetes.
2018 was a stellar year for CNCF. We are well-positioned both financially and organizationally to continue our mission to make cloud native computing ubiquitous . We look forward to having you join us on this journey as we plan for a blockbuster 2019.
