I attended Kubecon + CloudNativeCon North America 2018 from December 10th to 13th at the Washington State Convention Center in Seattle. Hosted by the Cloud Native Computing Foundation (CNCF), Kubecon + CloudNativeCon is an event that gathers Kubernetes and Cloud Native open source technology adopters to discuss and share the latest information about Kubernetes and related projects.
In 2015, only 500 people attended the event held in San Francisco. However, more than 8,000 people attended this year’s Kubecon. This is a clear indication of how much interest in Kubernetes has grown.
※ What is Kubernetes?
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Simply put, it is a container orchestration system. The most commonly used container is Docker. For more information, please refer below.

The conference was held over four days. The pre-event sessions began on December 10th and the official conference kicked off with the keynote on the 11th. With more than 300 different sessions and nearly 100 exhibition booths, this year was the biggest Kubecon to date.
CNCF projects are full stack open source components in a cloud-native environment and are divided into three different application maturity tiers: Sandbox, Incubating and Graduated. Sandbox are projects that have been adopted by innovators, Incubating are projects that have been adopted by early adopters while Graduated projects are those that have crossed the Chasm and have been adopted by the late majority.
A total of three open source projects have achieved Graduated maturity level. Beginning with Kubernetes last March, Prometheus and Envoy also achieved Graduated maturity level in August and November respectively.
- Kubernetes (https://kubernets.io)
: On Github, Kubernetes is ranked 9th for commits and 2nd for authors and issues out of 1.5 million projects as of March 2018. Many companies including Uber, the New York Times and eBay are already using Kubernetes.
- Prometheus (https://prometheus.io/)
: Prometheus is an open source systems monitoring and alerting toolkit that specializes in collecting time series data for machine-centric monitoring as well as monitoring of highly dynamic service-oriented architectures. Since its inception in 2012, many companies have adopted Prometheus.
- Envoy (https://www.envoyproxy.io/)
: Envoy is an open source service proxy designed by Lyft to support cloud-native applications. In a microservice architecture, networking services are complex and can cause numerous issues. However, by running a proxy such as Envoy for each service, all service traffic can be controlled and any subsequent issues can be resolved at the network level.
Many projects are currently in the Incubating maturity level including Fluentd, gRPC and Jaeger. Recently, Helm, the package manager for Kubernetes, and Harbor, a container image registry, were promoted to Incubating status.
Since I am a developer, not a cloud engineer, most of the sessions I attended were cloud-native development demonstrations targeted towards developers. I also attended sessions about Software Continuous Integration and Delivery because they are subjects of personal interest. Many renowned entrepreneurs shared their first-hand experience during the sessions.
During this session, SAP shared their experience of migrating their existing Jenkins based build system to a VM+Chef environment with Kubernetes. While explaining how they configured solid clusters using kubeadm and ran Jenkins using helm charts and shell scripts, SAP captivated everyone’s attention by explaining the different problems they experienced during each step with humor.
GitLab talked about their move from monolith systems to Kubernetes-based microservices. They explained how continuing existing product development and serving customers on legacy software while moving to microservices was akin to trying to repair a race car competing in a race without any pit stops.
Matt Farina, a member of Samsung SDSRA Cloud Native Computing Team and a Helm project Maintainer, was the presenter for this session. With Helm 3 currently in development, Matt provided a brief overview and also talked about the past, present and future of the Kubernetes package manager.
I also had the pleasure of attending two Hands-on-Labs.
Streamlining Your Kubernetes Application Development with Draft & Brigade, Microsoft
This Hands-on-Lab session taught developers how to deploy applications in a cloud environment using Draft and Brigade, regardless of familiarity with Kubernetes.

During this Hands-on-Lab, IBM discussed the background and functions of the ever-popular Istio. The session also included a brief application deployment demonstration using Istio.

Many companies are already using Kubernetes to solve the challenges of developing and deploying applications in a very competitive global market. Moreover, companies like Google, AWS, IBM,and Oracle are urging companies to migrate workloads to their cloud. They also emphasize how easy it is to migrate applications from other clouds to their own cloud thanks to cloud native technologies.
Nowadays, cloud-native application development and service provisioning have become the default choice. This year’s Kubecon has shown that Kubernetes plays an integral role in this.
As a developer, I am now faced with the difficult task of trying to figure out how to switch my previous development methods to cloud-native. Migrating to a cloud-based build, distribution and operation environment is another dilemma. However, my new found knowledge of Kubernetes and Cloud Native technologies also presents me with the limitless possibilities of a blank slate.
In closing, I thank you for reading my Insight Report about my Kubecon+CloudNativeCon North America 2018 experience and wish you great success in all of your endeavors.
