內容大綱

這裡僅是簡單摘要，完整內容請參閱報告原文、或 SDN x Cloud Native Meetup #27 活動錄影內容討論。

Survey Methodology: Scope v.s Industry
(Release cycles)+++ v.s (Check in code)-
(Use of containers in prod)+++
(Cultural changes)++
Serverless
- Using/planning to use: 70%
- Hosted : Installable = 80% : 20%
Kubernetes
- Helm: ~70% (Packaging)
- Not use tracing: 23%

The majority of respondents (71%) were from organizations with at least 100 employees, the largest portion of these coming from enterprises with more than 5,000 employees (30%).
- 調查取樣偏向中大型企業。
Two-thirds of the respondents were in the software and technology industry, with the remainder coming from other professional service industries.
- 前六大受訪產業：軟體、科技、金融服務、顧問諮詢、電信通訊、容器雲端相關。超過 60% 受訪者。
調查結果與亞洲、傳統產業、地端現況有差距。亞洲區受訪者佔這個調查的 17%。

Release cycles continue to accelerate.
Those with daily release cycles increased from 15% in 2018 to 27%, and weekly release cycles have increased 20% to 28%.
Comparing the data from 2019 and 2018, respondents are checking in code less frequently.
Vendor lock-in strategy
- 可能因企業規模、時程、應用場景而有所不同?
- Enterprise
- SME
- Start-up

Most notably, the use of containers in production increased significantly.
This year, 84% of respondents are using containers in production, an impressive jump from 73% in 2018, and from 23% in our first survey in 2016.
- Hint: Ref to SMR (4/5) Industry.
According to CNCF’s Cloud Native Landscape, there are more than 109 tools to manage containers, but 89% are using different forms of Kubernetes.
- Hint: Ref to SMR (4/5) Industry.
Cultural challenges with the development team remain the top challenge in using/deploying containers (43%).
- 導入與實作期間最大挑戰：文化改變。

While use in production is still rather low with 18% of those who responded indicating they use a service mesh project, 47% are evaluating the use of a service mesh.
Service Mesh:
- Istio (69%) and Linkerd (64%) were the top two tools being evaluated, suggesting they will see significant increases in use in production in coming years.
Storage:
- Top-3 are public cloud storage projects.
Serverless:
- 60%~70% 受訪者，正在使用 (40%~50%) 或是打算使用 (20%) Serverless。
- Of those who are using serverless, 80% use a hosted platform and 20% use installable software.
- Of the hosted platforms in use, the top tool is AWS Lambda (53%). Google Cloud Functions (18%) and Azure Functions (14%) are a distant second and third.

99% of respondents indicated they are using or evaluating at least one graduated or incubating CNCF technology in production.
Prometheus and CoreDNS also saw considerable jumps in use in production.
For incubating projects, Helm saw the largest increase since last year, growing 41% to reach 69% usage in production. etcd was the most widely used, with 83% use in production.

Of those using Kubernetes, most respondents have 2-5 clusters in production (43%).
Helm remains the most popular tool for packaging Kubernetes applications.
the majority (70%) of respondents plan to autoscale their stateless applications, followed by 40% for task/queue processing applications, and 34% of stateful applications.
Of those who are not using Kubernetes autoscaling capabilities, 35% do not want to autoscale any works at this time, and 12% are using a third-party solution.
Namespaces are the most popular way to separate Kubernetes applications for all respondents, including those with multiple teams.
23% report that they do not use tracing, compared with just over 3% for both monitoring and logging.

Minikube (39%) and Docker Kubernetes (32%) are the most popular Kubernetes environments during local container development.

這次首次嘗試使用 Marp for VS Code 製作簡報投影片，這次投影片的 Markdown 原始檔案可以參考。

主要使用 Markdown 語法，加上一些 Marp 預設自定義的參數語法，限制頗多，特別是一開始我想嘗試只使用預設值狀態下，但相對帶來的優點也是有（對我來說），例如：

之後再另篇記錄。

另外也歡迎大家到 AWS User Group Taiwan 逛逛聊聊 :)
