\u00c4mnet DevOps och IaC \u00e4r mycket popul\u00e4rt och utvecklas snabbt. Men de flesta f\u00f6rfattare ber\u00f6r enbart de tekniska problemen p\u00e5 denna v\u00e4g. Jag kommer ist\u00e4llet att beskriva de problem som \u00e4r typiska f\u00f6r stora f\u00f6retag. Jag har inga l\u00f6sningar \u2014 problemen \u00e4r i stort sett fatala och ligger inom omr\u00e5dena byr\u00e5krati, revision och \"soft skills\". <\/p>\n

\nOm artikeln har ett s\u00e5dant namn, s\u00e5 kommer Daenerys, som har g\u00e5tt \u00f6ver till Enterprise, att agera katt.

\nUtan tvekan sker det nu en kollision mellan gammalt och nytt. Och ofta finns det ingen som har r\u00e4tt eller fel i dessa kollisioner. S\u00e5 har det blivit. Men f\u00f6r att inte bara prata ska vi b\u00f6rja med denna sk\u00e4rm:<\/p>\n

\nDetta \u00e4r s\u00e5 kallad Change Request. Du ser ungef\u00e4r en tredjedel av f\u00e4lten som m\u00e5ste fyllas i fr\u00e5n olika register, medan de andra f\u00e4lten finns p\u00e5 andra flikar. Detta dokument m\u00e5ste fyllas i f\u00f6r att kunna till\u00e4mpa skriptet p\u00e5 production. servern<\/a>, eller f\u00f6r att ladda upp nya filer och \u00f6verhuvudtaget f\u00f6r\u00e4ndra n\u00e5got. <\/p>\n

Antalet f\u00e4lt \u00e4r s\u00e5dant att jag har skrivit min egen lilla automatisering f\u00f6r att fylla i dessa f\u00e4lt. Denna sida \u00e4r utformad p\u00e5 ett s\u00e5dant s\u00e4tt att inga automatiseringsverktyg kan se dess f\u00e4lt, och den enda m\u00f6jliga l\u00f6sningen var att anv\u00e4nda AutoIt f\u00f6r att helt enkelt klicka med musen p\u00e5 koordinater. Bed\u00f6m graden av desperation f\u00f6r att v\u00e5ga g\u00f6ra n\u00e5got s\u00e5dant:<\/p>\n

\nS\u00e5 du tar jenkins, chef, terraform, nexus och annat och jublar \u00f6ver att du distribuerar allt detta p\u00e5 din dev. Men det kommer en tid att skicka detta till QA, UAT och PROD. Du har artefakten i Nexus och f\u00e5r ett meddelande fr\u00e5n DBA med ungef\u00e4r f\u00f6ljande text:<\/p>\n

B\u00e4sta h\u00e4lsningar,<\/p>\n

F\u00f6r det f\u00f6rsta, din nexus har jag inte tillg\u00e5ng till er Nexus.
\nF\u00f6r det andra, alla \u00e4ndringar m\u00e5ste dokumenteras som en Change Request.
\nSQL-skripten m\u00e5ste du extrahera fr\u00e5n Nexus och bifoga till Change Request.
\nOm \u00e4ndringen inte \u00e4r en n\u00f6dsituation, b\u00f6r detta g\u00f6ras inom 7 dagar efter releasen (exklusivt under helgen).
\nN\u00e4r din Change Request har godk\u00e4nts av en massa m\u00e4nniskor kommer DBA att k\u00f6ra ditt skript och till och med skicka en sk\u00e4rmdump av resultatet via e-post.<\/p>\n

Med v\u00e4nlig h\u00e4lsning, din DBA som har jobbat h\u00e4r sedan mainframe.

Vet ni vad detta p\u00e5minner mig om? Halvautomatisering: roboten h\u00e5ller fast maskinen medan arbetaren sl\u00e5r p\u00e5 den med en sl\u00e4gga. Ja, vad \u00e4r egentligen vitsen med Nexus om allt sedan g\u00f6rs helt manuellt?<\/p>\n

Men man ska inte skylla p\u00e5 Enterprise! Det \u00e4r sj\u00e4lvklart blodigt, men all denna byr\u00e5krati med Change Requests \u00e4r n\u00f6dv\u00e4ndig och kommer fr\u00e5n revisorer. Enterprise \u00e4r tvunget att arbeta s\u00e5 h\u00e4r, och punkt slut. Det finns inget annat s\u00e4tt. Revision \u00e4r en oerh\u00f6rt konservativ sak. Hur mycket som helst har sagts om att l\u00e5nga, pseudokomplexa och ofta f\u00f6r\u00e4ndrade l\u00f6senord \u00e4r d\u00e5ligt, men f\u00f6retag kommer att vara den sista platsen d\u00e4r detta \u00e4ndras. Detsamma g\u00e4ller f\u00f6r deployment och allt annat.<\/p>\n

F\u00f6r \u00f6vrigt f\u00f6rs\u00f6kte jag en g\u00e5ng skapa en fil f\u00f6r terraform, men jag lyckades inte. Jag snubblade \u00f6ver v\u00e4rdet av taggen 'Project Accounting Billing Code', som jag aldrig lyckades f\u00e5 veta \u2014 jag saknade soft skills.<\/p>\n

Jag tar inte ens upp \u00e4mnet passiv ludditism \u2014 \u00e5h, er automatisering hotar min jobbs\u00e4kerhet, jag vill inte l\u00e4ra mig n\u00e5got nytt, s\u00e5 jag kommer att tysta sabotera.<\/p>\n

Och vad kan det egentligen finnas f\u00f6r l\u00f6sning? ITSM-systemet har en extremt primitiv API f\u00f6r att automatiskt generera dokument. Och \u00f6verhuvudtaget kommer de flesta s\u00e5dana system fr\u00e5n mainframe-eran. Kanske n\u00e5gon vet om verkligen moderna ITSM-system? Kanske n\u00e5gon har framg\u00e5ngsrik erfarenhet av integration av moderna DevOps och byr\u00e5krati? <\/b>Det handlar sj\u00e4lvklart inte om rena s\u00e4ljwebbplatser, d\u00e4r det verkligen kan finnas en deployment varje dag, utan, exempelvis, banksektorn som st\u00e5r under revisorer och har en mycket stark isolering av h\u00f6gre milj\u00f6er.<\/p>\n

Men gl\u00f6m inte att alla era fantasier \u00e4r begr\u00e4nsade av revisionen. Och det f\u00f6r\u00e4ndrar allt. Jag ser fram emot era kommentarer!
