需要考慮的幾點(diǎn)
1缘琅、Agentless Agent
2粘都、語(yǔ)言 Python Ruby
3、簡(jiǎn)單 可讀性 可寫(xiě)行
4刷袍、性能 執(zhí)行速度 管理節(jié)點(diǎn)數(shù)
5驯杜、細(xì)分場(chǎng)景支持 應(yīng)用部署 配置管理 作業(yè)編排
1、如果機(jī)器規(guī)模非常小做个，少于20臺(tái)完全可以手工來(lái)維護(hù)鸽心，因?yàn)橐话闱闆r下每臺(tái)機(jī)器的配置都可能不大相同滚局，使用手工管理是最有效率的。
2顽频、隨著機(jī)器規(guī)模的擴(kuò)大藤肢，根據(jù)自己的實(shí)際情況選擇對(duì)應(yīng)的配置管理工具，比如說(shuō)人員的技術(shù)棧糯景、編寫(xiě)配置的的能力嘁圈、對(duì)于管理節(jié)點(diǎn)數(shù)量以及執(zhí)行速度要求等。一般情況下熟悉Python蟀淮，使用Ansible是一種好的選擇最住。
3、如果機(jī)器規(guī)模非常大怠惶，大于5000臺(tái)涨缚，可以考慮使用側(cè)重于編排類的工具使用，或者考慮自定義與擴(kuò)展開(kāi)源軟件策治，或者考慮商業(yè)軟件脓魏。
