Alegri conseille depuis 2015 sur SAP on Azure. Il convient tout d'abord d'examiner quelques conditions marginales : Qu'entend-on par cloud ? SaaS, PaaS, IaaS ; public ou priv\u00e9 ? Quel est l'objectif ? Flexibilit\u00e9, optimisation des co\u00fbts, \"pas de personnel pour l'infrastructure\/les bases de donn\u00e9es\/les applications !\" ou agilit\u00e9 ?<\/p>\n
Une vue d'ensemble du paysage syst\u00e8me et des services constitue la base de la planification. Un nettoyage du paysage technique et une mise \u00e0 jour du catalogue de services suivent. Il est possible ici de r\u00e9silier jusqu'\u00e0 25 pour cent des syst\u00e8mes.<\/p>\n
Vient ensuite la planification de la transition : en fonction de son ampleur, plusieurs phases peuvent \u00eatre utiles. Celles-ci se chevauchent g\u00e9n\u00e9ralement, de sorte qu'une gestion rigoureuse du programme est n\u00e9cessaire. L'une des premi\u00e8res phases est le PoC, au cours duquel les conditions marginales et les hypoth\u00e8ses techniques et organisationnelles sont test\u00e9es.<\/p>\n
C'est \u00e9galement l\u00e0 que les tests de charge et les tests de r\u00e9gression sont effectu\u00e9s et valid\u00e9s, le cas \u00e9ch\u00e9ant. Les changements organisationnels ne doivent pas \u00eatre sous-estim\u00e9s : modifications des profils de poste, des exigences et des connaissances requises. Avec un partenaire exp\u00e9riment\u00e9 \u00e0 ses c\u00f4t\u00e9s, ce processus de changement peut toutefois \u00eatre men\u00e9 \u00e0 bien avec peu de risques et en toute transparence.<\/p>","protected":false},"excerpt":{"rendered":"
