自动和混合发布周期越来越受欢迎。 使用手动发布周期的用户已经从去年的 31% 下降到 17%。Automated and hybrid release cycles are becoming more popular. Those using manual release cycles have dropped significantly to 17% from 31% last year.
少于半数的单位使用最受欢迎的混合发布周期，该方法相比去年的 46% 略有增加。使用自动发布周期的用户从 21% 增长到了 30%。随着越来越多的单位继续使用 CI/CD 工具，预期会有后续会有更多用户使用自动发布周期。Just under half of organizations have hybrid release cycles, the most popular approach, up slightly from 46% last year. Those using automated release cycles have increased to 30% from 21%, and we expect to see this growth continue as more organizations continue to adopt CI/CD tools.
公有云重回榜首，混合云和多个云蓄势待发。 公有云使用排名第一，46% 的调查对象将其作为首选数据中心类别。这个数字比去年的 36%有所增长，但仍然低于 2018 年 51% 的水平。另有 45% 的用户使用私有云，42% 使用混合云，两项均比去年小幅增长。本次调查首次了解了“多个云”的使用情况，结果显示 22% 调查对象选择了多个云。未来随着越来越多的单位寻求使用最佳解决方案，混合云和多个云有望实现使用增长。Public cloud is back on top, but hybrid and multi-cloud are poised for growth. Public cloud usage ranked No. 1, with 46% of respondents naming it as their top data center type. This is up from 36% last year, but down from 2018 when 51% were using public cloud. Private, 45% and hybrid, 42% also both had small increases over last year. The survey asked about “multi-cloud” for the first time, and it was chosen by 22% of respondents. We expect to see growth in future surveys among hybrid and multi-cloud as more organizations look to take advantage of best-of-breed solutions.
注：允许调查对象选择一个以上答案，因此可能造成重复统计。未来调查中，我们会寻求改进。Note that respondents were allowed to select more than one answer, which may be causing overlap. We will resolve this for future surveys.
使用超过 5,000 台机器的用户增加。 但用户使用最多的数量为 6-100 台，今年这个区间的用户占 47%，去年为 44%。仅有 15% 的单位使用 5,000 台以上机器，但这一比例比去年的 10%有所增长。There has been an increase in those using more than 5,000 machines. However,the most popular number isbetween 6-100 machines, as noted by 47% of respondents versus 44% last year.
