Due to the machine-readable specification file's application, IaC referred to as Infrastructure as Code, cloud infrastructure can automatically be customized, configured and managed. Automation of IaC minimizes the human error, builds solid teams, and APIs standardize the engagement with cloud services which helps in building the effective devops practices. The financial institutions try to overcome these challenges in cloud computing for instance, data redundancy and disaster recovery. They also have to provide regulatory compliance, improve data protection and cost optimization. In a nutshell, IaC has the capacity to deliver such benefits as increased compliance and security due to standardized, audit-friendly and version controlled infrastructure setups, increased automation and standardization translating to less opportunity for errors and staff workload reduction, improved responsiveness to rapidly changing business demands owing to shorter provisioning and scaling cycles, better resource utilization and cost optimization through the automated implementation and termination of infrastructure components. The article focuses on the adoption of IaC as a significant component of the financial sector cloud operations that regard the compliance and efficiency issues.
