O tema DevOps e IaC \u00e9 muito popular e est\u00e1 se desenvolvendo rapidamente. No entanto, a maioria dos autores aborda apenas quest\u00f5es t\u00e9cnicas nesse caminho. Eu descreverei os problemas caracter\u00edsticos de grandes empresas. N\u00e3o tenho solu\u00e7\u00f5es \u2014 os problemas, em geral, s\u00e3o fatais e est\u00e3o na \u00e1rea de burocracia, auditoria e \"soft skills\". <\/p>\n

\"A
\nSe o t\u00edtulo do artigo \u00e9 esse, ent\u00e3o como bode expiat\u00f3rio teremos Daenerys, que mudou de lado para a Enterprise.
\n<\/a><\/noindex>
\nSem d\u00favida, atualmente est\u00e1 ocorrendo um confronto entre o antigo e o novo. E muitas vezes nessas colis\u00f5es n\u00e3o h\u00e1 nem certo nem errado. Assim aconteceu. Mas, para n\u00e3o ser apenas ret\u00f3rico, vamos come\u00e7ar com esta tela:<\/p>\n

\"A
\n
\nEste \u00e9 o chamado Change Request. Voc\u00ea v\u00ea cerca de um ter\u00e7o dos campos que precisam ser preenchidos a partir de diversos diret\u00f3rios; os outros campos est\u00e3o em outras abas. Esse documento precisa ser preenchido para aplicar o script em produ\u00e7\u00e3o. servidor<\/a>, ou carregar novos arquivos e, em geral, alterar qualquer coisa. <\/p>\n

A quantidade de campos \u00e9 tal que escrevi minha pr\u00f3pria pequena automa\u00e7\u00e3o para preench\u00ea-los. Al\u00e9m disso, essa p\u00e1gina \u00e9 feita de tal modo que nenhum meio de automa\u00e7\u00e3o consegue ver seus campos, e a \u00fanica solu\u00e7\u00e3o poss\u00edvel foi usar o AutoIt para simplesmente clicar com o mouse nas coordenadas. Avaliem o grau de desespero para se arriscar a fazer isso:<\/p>\n

\"A
\n
\nEnt\u00e3o voc\u00ea pega Jenkins, Chef, Terraform, Nexus e outros, e alegremente implementa tudo isso no seu dev. Mas chega o momento de enviar isso para QA, UAT e PROD. Voc\u00ea tem o artefato Nexus e recebe um email do DBA com algo assim:<\/p>\n

Prezado,<\/p>\n

Primeiro, o seu Nexus voc\u00ea pode ter, eu n\u00e3o tenho acesso ao seu Nexus.
\nEm segundo lugar, todas as altera\u00e7\u00f5es devem ser formalizadas como Change Request.
\nOs scripts SQL precisam ser extra\u00eddos do Nexus e anexados ao Change Request.
\nSe a altera\u00e7\u00e3o n\u00e3o for uma Emerg\u00eancia, isso deve ser feito at\u00e9 7 dias ap\u00f3s o lan\u00e7amento (exclusivamente no fim de semana).
\nQuando o seu Change Request for aprovado por v\u00e1rias pessoas, o DBA executar\u00e1 seu script e at\u00e9 enviar\u00e1 um screenshot do resultado por email.<\/p>\n

Atenciosamente, seu DBA que trabalha aqui desde a \u00e9poca do mainframe.
\n<\/i><\/p><\/blockquote>\n

Sabe o que isso me lembra? Uma semi-automa\u00e7\u00e3o: o rob\u00f4 segura a base, enquanto o trabalhador bate nela com um martelo. Realmente, qual \u00e9 o sentido nesse Nexus, se depois tudo \u00e9 feito completamente manualmente?<\/p>\n

Mas n\u00e3o devemos culpar o Enterprise por isso! Ele \u00e9, sem d\u00favida, sanguin\u00e1rio, mas toda essa burocracia com os Change Requests \u00e9 for\u00e7ada e vem dos auditores. O Enterprise deve operar assim, e ponto final. N\u00e3o pode ser diferente. E a auditoria \u00e9 uma coisa muito conservadora. Quanto se falou, por exemplo, que senhas longas, pseudo-complexas e frequentemente alteradas s\u00e3o ruins, mas os enterprises ser\u00e3o o \u00faltimo lugar onde isso mudar\u00e1. O mesmo vale para implanta\u00e7\u00f5es e tudo mais.<\/p>\n

A prop\u00f3sito, eu tentei criar um arquivo para terraform na \u00e9poca, mas n\u00e3o consegui. Esbarrei no valor da tag 'Project Accounting Billing Code', que n\u00e3o consegui descobrir \u2014 me faltaram soft skills.<\/p>\n

Nem estou falando do tema do ludismo passivo \u2014 ah, sua automa\u00e7\u00e3o amea\u00e7a minha seguran\u00e7a no emprego, n\u00e3o quero aprender nada novo, ent\u00e3o vou sabotar silenciosamente.<\/p>\n

Qual poderia ser a solu\u00e7\u00e3o, afinal? O sistema ITSM possui uma API extremamente primitiva para gerar documentos automaticamente. E, de modo geral, a maioria desses sistemas vem desde a era dos mainframes. Algu\u00e9m conhece sistemas ITSM realmente modernos? Algu\u00e9m tem experi\u00eancia bem-sucedida na integra\u00e7\u00e3o de DevOps modernos com burocracia? <\/b>Claro, n\u00e3o se trata de sites apenas voltados para vendas, onde realmente pode haver implanta\u00e7\u00f5es di\u00e1rias, mas, por exemplo, no setor banc\u00e1rio, que est\u00e1 sob auditoria e tem uma forte isola\u00e7\u00e3o dos ambientes superiores.<\/p>\n

S\u00f3 n\u00e3o se esque\u00e7am de que todas as suas fantasias s\u00e3o limitadas pela auditoria. E isso muda tudo. Aguardando voc\u00eas nos coment\u00e1rios!
