Today, we are publishing our first CNCF Technology Radar, a new initiative from the CNCF End User Community. This is a group of over 140 top companies and startups who meet regularly to discuss challenges and best practices when adopting cloud native technologies. The goal of the CNCF Technology Radar is to share what tools are actively being used by end users, the tools  they would recommend, and their patterns of usage.


How it works

A technology radar is an opinionated guide to a set of emerging technologies. The popular format originated at Thoughtworks and has been adopted by dozens of companies including ZalandoAOEPorsche, Spotify, and Intuit.

The key idea is to place solutions at one of four levels, reflecting advice you would give to someone who is choosing a solution:

The CNCF Technology Radar is inspired by the format but with a few differences:

Our first technology radar focuses on Continuous Delivery.

CNCF Technology Radar: Continuous Delivery, June 2020

During May 2020, the members of the End User Community were asked which CD solutions they had assessed, trialed, and subsequently adopted. 177 data points were sorted and reviewed to determine the final positions.

The Themes

The themes describe interesting patterns and editor observations:

  1. Publicly available solutions are combined with in-house tools: Many end users had tried up to 10 options and settled on adopting 2-4. Several large enterprise companies have built their own continuous delivery tools and open sourced components, including LunarWay’s release-manager, Box’s kube-applier, and stackset-controller from Zalando. The public cloud managed solutions on the CNCF landscape were not suggested by any of the end users, which may reflect the options available a few years ago.
  2. Helm is more than packaging applications: While Helm has not positioned itself as a Continuous Delivery tool (it’s the Kubernetes package manager first), it’s widely used and adopted as a component in different CD scenarios. 
  3. Jenkins is still broadly deployed, while cloud native-first options emerge. Jenkins and its ecosystem tools (Jenkins X, Jenkins Blue Ocean) are widely evaluated and used. However, several end users stated Jenkins is primarily used for existing deployments, while new applications have migrated to other solutions. Hence end users who are choosing a new CD solution should assess Jenkins alongside tools that support modern concepts such as GitOps (for example, Flux).

What’s next

The next CNCF Technology Radar is targeted for September 2020, focusing on a different topic in cloud native such as security or storage. Vote to help decide the topic for the next CNCF Technology Radar.

About the methodology

In May 2020, the 140 companies in the CNCF End User Community were asked to describe what their companies recommended for different solutions: Hold, Assess, Trial, or Adopt. They could also give more detailed comments. As the answers were submitted via a Google Spreadsheet, they were neither private nor anonymized within the group.

33 companies submitted 177 data points on 21 solutions. These were sorted in order to determine the final positions. Finally, the themes were written to reflect broader patterns, in the opinion of the editors.
