Kubernetes is Used in Production by 72% in China
2019 CNCF中国云原生调查 – 中国72％的受访者生产中使用Kubernetes
At CNCF, we regularly survey our community to better understand the adoption of open source and cloud native technologies. For the third time, we conducted the Cloud Native Survey China in Mandarin to gain deeper insights into the pace of cloud native adoption in China, and how that’s empowering developers and transforming development in this large and growing community. This report builds on the first two China reports, published in March 2018 and November 2018.
Key Takeaways of Cloud Native Survey China
- 49% of respondents use containers in production, with another 32% planning to do so. This is a significant increase from November 2018 when only 20% used containers in production.
- 72% of respondents use Kubernetes in production, up from 40% in November 2018.
- The use of public cloud dropped to 36% from 51% in November 2018, replaced by a new option of hybrid with 39%.
- The use of CNCF projects is growing exponentially. CNCF now hosts four projects that were born in China and are more broadly used in the region: Dragonfly and KubeEdge, which are incubating, and Harbor and TiKV, which recently graduated.
The Cloud Native Survey China 2019 included responses from 300 people – 97% of which were in Asia, predominantly in China.
We know that containers have transformed cloud-based infrastructures but, over the last year, container use in production has become the norm. According to our global 2019 Cloud Native Survey, which we released earlier this year, 84% of respondents use containers in production, making container use ubiquitous across the globe.
The China survey indicates that while container usage in China lags behind global adoption, it is gaining momentum. Nearly half (49%) of respondents in the China survey use containers in production – a jump from 32% in our March 2018 survey and from 20% in November 2018.
Far fewer members in China plan to use containers in production – 32% versus 57% in our March 2018 survey and 40% in November. This means many organizations have put container plans into action and are no longer in the planning stage. However, there is still room for growth, which we fully expect to continue.
As use in production grows, the presence of containers in testing environments has dropped. About 28% of China survey respondents are currently using containers in testing – up slightly from 24% in March 2018 but down against 42% in the November 2018 survey.
While containers bring phenomenal advantages, they still pose challenges. These have changed over time, but the challenge of complexity has remained consistent. In the China survey, complexity was named the top challenge by 53% of respondents – compared to 44% in our March 2018 survey, where it was also top, and 28% in November 2018, where it ranked third.
Security ranked second in terms of challenges, with 39% of respondents. It was the first time security was listed as a top challenge. Lack of training and networking tied for third at 36%, while reliability and monitoring were chosen as deployment challenges by 35% of survey respondents.
尽管容器带来了惊人的优势，但也带来了挑战。随着时间的推移发生了变化，但是复杂性的挑战一直保持不变。在中国调查中，53％的受访者将复杂性列为最大挑战。 相比之下，2018年3月的调查中， 44％受访者认为复杂性是最大挑战，占比最高。2018年11月的调查中28％的受访者，占比排第三。
Kubernetes is emerging in the industry as a common platform for container orchestration, and the CNCF community in China has seen a massive spike in adoption. 72% of respondents reported using Kubernetes in production – a dramatic increase from 40% in November 2018.
Consequently, the number of those evaluating Kubernetes has fallen, dropping to 17% from 42%.
We also see growth in the size of production clusters of Kubernetes at both ends of the deployment spectrum. Most organizations responding to the China survey are using fewer than 10 clusters, but there has been an increase in those running more than 50. This is likely driven by the number of new respondents using containers in production, while those using production containers are adding more clusters.
Thirty-six percent of respondents had two to five clusters, up from 25% in November 2018, with half using between one and five and 70% between one and 10. Just over 13% had more than 50 clusters in production versus 5% in November 2018.
Helm is the most popular method of packaging Kubernetes applications, chosen by 54% of respondents.
NGINX (54%) was the most used Kubernetes ingress provider, followed by HAProxy (18%), F5 (16%), and Envoy (15%).
Separating Kubernetes Applications
Managing objects in a cluster can be a challenge, but namespaces help by filtering and controlling them as groups. 71% of respondents separate their Kubernetes applications with namespaces. Of those that use Kubernetes with multiple teams, 68% use namespaces.
Monitoring, Logging, and Tracing
It is more common for those using monitoring, logging, and tracing solutions to run on-premise vs. hosted via a remote server. 46% of respondents use monitoring tools on-premise, while 20% run them via a remote service. Fewer respondents use logging and tracing overall, but 26% run tracing on-premise vs. 20% via a remote service. 21% run tracing tools on-premise and another 21% via a remote service.
对于那些使用监控，日志和跟踪解决方案的用户来说，本地运行还是通过远程服务器托管更普遍。 46％的受访者使用本地监控工具，而20％的受访者通过远程服务运行。 整体上使用日志和跟踪的受访者较少，但是26％的受访者在本地运行跟踪，而20%通过远程服务运行跟踪。 21％的企业内部运行跟踪工具，另外21％的企业通过远程服务运行。
The speed of development and deployment has accelerated in China thanks to the combined power of cloud and containers, supported by Continuous Integration (CI) and Continuous Delivery (CD). Our survey quantifies development speed by the frequency developers check in code into repositories. Just over a third, 35%, check in code multiple times a day. 43% percent check in code a few times a week, and 16% check in a few times each month.
由于持续集成（CI）和持续交付（CD）的支持，云和容器的强大功能共同推动了中国的开发和部署速度。 我们的调查通过开发者将代码检入存储库的频率来量化开发速度。35％的受访对象每天多次检入代码。 43%的每周几次检入代码，16％的每月几次检入代码。
Most respondents work to weekly release cycles (43%) while just over a fifth (21%) work on monthly cycles, and 18% on daily cycles. 12% of those surveyed are working to ad-hoc schedules.
Many consider the foundation of successful CI/CD to be the automation of processes. However, our China survey revealed that purely automated environments are relatively rare – just 21% are employing automatic release cycles, with 31% relying on manual processes. The most popular response was hybrid, with 46%.
许多人认为成功的CI / CD的基础是流程自动化。 但是，我们在中国的调查显示，纯自动化环境相对较少-只有21％的受访对象采用自动发布周期，而31％依靠手动流程。 最受欢迎的是混合方式，占46％。
CI/CD is the philosophy and technology that enables agile and flexible delivery and lifecycle management of cloud native systems. The most popular CI/CD tool with the China community, Jenkins, is used by just over half of the community, 53%, and GitLab is used by 40%.
CI / CD是实现云原生系统灵活交付和生命周期管理一种哲学和技术。 Jenkins是中国社区中最受欢迎的CI / CD工具，占社区的一半以上53％，GitLab占40％。
Cloud vs. On-Premise
Cloud is growing, but this year’s China survey revealed a shift away from public cloud, consolidation of private, and the emergence of hybrid cloud. The use of public cloud appears to have peaked in our November 2018 survey at 51%, while this year, it dropped to 36%. Private cloud held steady, 42% versus 43% in November 2018. Hybrid cloud, a new option for this year, emerged at 39%.
Cloud Native Projects
CNCF stewards a large number of open source projects critical to the development, deployment, and lifecycle management of cloud native. CNCF projects are growing exponentially in China. For example, the Prometheus monitoring and alert system is used by 57% of respondents, up dramatically from 16% in March 2018. CoreDNS is now used by 35%, up from 10% in March 2018. The Containerd runtime has also seen staggering growth – up from 3% in March 2018 to 29% at the start of 2019.
CNCF also hosts four projects created in China that are more broadly used in the region. Dragonfly (17% use in production) and KubeEdge (11% use in production) were two of the most used Sandbox projects. Both are now incubating projects. Harbor and TiKV, which are graduated projects, are used in production by 27% and 5%, respectively.
CNCF管理着大量的开源项目，这些项目对于云原生的开发，部署和生命周期管理至关重要。 CNCF项目在中国呈指数级增长。 例如57％的受访者使用Prometheus监控和警报系统，较2018年3月的16％有显著增长。现在35％受访者使用CoreDNS， 2018年3月只有10％。Containerd运行时也实现了惊人增长 –从2018年3月的3％增长到2019年初的29％。
CNCF还托管了在中国创建的四个项目，这些项目在该地区得到了更广泛的应用。Dragonfly（17％受访者在生产中使用）和KubeEdge（11％受访者在生产中使用）是最常用的两个沙箱项目， 现在两个都在孵化阶段。 Harbor和TiKV是毕业项目，分别有27％和5％受访者用于生产。
There has been a shift in the perceived benefits of using cloud native projects in production since CNCF’s last China survey:
- Faster deployment times appeared for the first time as the top benefit, cited by 47%.
- Improved scalability retained its earlier, number two position with 35%.
- Cost savings remained third with 33%.
- Improved developer productivity, cloud portability, and improved availability tied for fourth at 31%. In November 2018, availability had been number one and portability number four.
Serverless is being used as a hosted platform by 36% and as installable software by 22% of respondents in the China survey.
For those using serverless tools as a hosted platform, the top-three providers are Alibaba Cloud Function Compute (46%), AWS Lambda (34%), and a tie between Tencent Cloud Serverless Cloud Function and Huawei FunctionStage (12%).
For those using serverless tools as installable software, Kubeless came first at 29%, followed by Knative at 22%, and Apache OpenWhisk at 20%.
For 2019 we added new questions on cloud native storage and service mesh. These are the popular cloud native projects underpinning these benefits in active production environments:
The most used cloud native storage projects are Ceph (24%), Amazon Elastic Block Storage (EBS) (23%) and Container Storage Interface (CSI) (18%)
最常用的云原生存储项目是Ceph（24％），Amazon Elastic Block Storage（EBS）（23％）和容器存储接口（CSI）（18％）

The Cloud Native Community in China
CNCF now has nearly 50 members in China. China is also the third-largest contributor to CNCF projects (in terms of contributors and committers) after the United States and Germany.
We have several case studies from China-based companies, including:
- JD.com, which saves approximately 60% of maintenance time for its private image central repository with Harbor.
- China Minsheng Bank, which has increased delivery efficiency by 3-4x, and doubled resource utilization with Kubernetes.
- Ant Financial, which has seen at least tenfold improvement in terms of the operations with cloud native technology.
We also launched a Kubernetes and Cloud Native course in China taken by 20,000+ people, and recently finished the first Cloud Native + Open Source Virtual Summit China.
The China community learns about cloud native technologies in many different ways.
我们还在中国开设了20,000多人参加的Kubernetes and Cloud Native课程，最近还完成了首届中国 Cloud Native + Open Source虚拟峰会。
72% of China survey respondents learn about cloud native technologies through documentation. Each CNCF project hosts extensive documentation on their websites, which can be found here.
CNCF invests thousands of dollars per year in improving project documentation. This includes project documentation hosting, adding tutorials, how-to guides, and more.
Events are a popular way for respondents to learn about cloud native technologies.
41% of respondents selected KubeCon + CloudNativeCon as somewhere to learn about new technologies. The next virtual KubeCon + CloudNativeCon is scheduled for November 17-20.
Meetups and local events, like Cloud Native Community Groups, were selected by 37% of respondents as a way to learn about cloud native technologies.
41％的受访者选择KubeCon + CloudNativeCon作为学习新技术的地方。 下一个虚拟KubeCon + CloudNativeCon计划于11月17日至20日举行。
37％的受访者选择了聚会和本地活动，（例如Cloud Native Community Groups）作为了解云原生技术的一种方式。
22% of respondents learn about cloud native technologies through technical webinars, with another 8% selecting business-oriented webinars, and 8% selecting CNCF webinars.
CNCF has ramped up its webinar program, with regular webinars scheduled for Chinese audiences. You can see the upcoming schedule and view recordings, slides, and replays of previous webinars here.
