This report looks at DevOps in multi-cloud setup, focusing on IaC as part of the DevOps' Pillars.' Catering for extensive DevOps adop tion across different clouds, the discussion in this paper reveals the value of large -scale DevOps through reports based on simulated real -life scenarios and situations. The main findings reveal that IaC positively improves operationality, reliability and agility in the cycle process. But at the same time, it brings additional issues connected to the problem of cloud compatibility, safety, and the issue of cloud management. Thus, this report outlines recurrent problems and provides realistic recommendations to tackle such difficulties and maintain trustworthy and efficient DevOps when using multiple clouds. Through the enablement of IaC, organizations shall experience enhanced efficiency in day-to-day operations and float consolidation of development and operations teams, which, in the long run, create competitiveness in the cloud computing discourse.
