虛擬化、云、容器、服務(wù)器自動化以及軟件自定義網(wǎng)絡(luò)的初衷是簡化IT運(yùn)維,然而應(yīng)用了這些技術(shù)之后,很多組織發(fā)現(xiàn)它們不斷增長,蔓延成了一個無法管理的系統(tǒng)。這正是基礎(chǔ)設(shè)施即代碼的用武之地。在這本務(wù)實(shí)的指導(dǎo)之作中,來自ThoughtWorks的Kief Morris展示了如何有效地使用DeV0ps運(yùn)動所倡導(dǎo)的原則、時間和模式,來管理云時代的基礎(chǔ)設(shè)施。
對于系統(tǒng)管理員、基礎(chǔ)設(shè)施工程師、團(tuán)隊(duì)領(lǐng)袖以及架構(gòu)師來說,這是一本難得的佳作。它描述了可以用來實(shí)現(xiàn)基礎(chǔ)設(shè)施即代碼的多種工具、技巧和模式。在基弗·莫里斯著的這本《基礎(chǔ)設(shè)施即代碼(影印版)(英文版)》的三個部分中,你將學(xué)習(xí)用來創(chuàng)建和配置基礎(chǔ)設(shè)施元素的平臺和工具、使用這些工具的模式以及在你自身環(huán)境中落實(shí)基礎(chǔ)設(shè)施即代碼的實(shí)踐。
檢查那些當(dāng)企業(yè)采用新一代基礎(chǔ)設(shè)施技術(shù)時常掉入的陷阱
理解動態(tài)基礎(chǔ)設(shè)施平臺的能力和服務(wù)模型
學(xué)習(xí)提供、開通和配置核心基礎(chǔ)設(shè)置資源的工具
探索管理動態(tài)基礎(chǔ)設(shè)施的服務(wù)和工具
學(xué)習(xí)開通服務(wù)器、構(gòu)建服務(wù)器模板和更新運(yùn)行時服務(wù)器的特定模式和實(shí)踐
Kief Morris,ThoughtWorks首席云技術(shù)專家,已經(jīng)從事設(shè)計(jì)、構(gòu)建和運(yùn)行自動化IT服務(wù)器基礎(chǔ)設(shè)施相關(guān)工作接近20年。作為一名ThoughtWorks咨詢師,他和客戶一起工作,使用來自Lean、Continuous Delivery和DevOps的理念,幫助客戶規(guī)劃、設(shè)計(jì)并實(shí)現(xiàn)流程及系統(tǒng),以交付和托管軟件。
