Streamlining Multi-Cloud Infrastructure Orchestration: Leveraging Terraform as a Battle-Tested Solution

Cloud computing provides the agility required to dynamically adjust applications in response to changing demands. Despite the proliferation of cloud service providers, the issue of vendor lock-in continues to pose significant challenges. Recent service disruptions have underscored the perils of exclusive reliance on a single provider. Existing cloud orchestration tools, while designed to mitigate these issues by facilitating deployments across multiple cloud providers, are often bound to provider-specific models. This necessitates users' familiarity with the unique offerings of each provider and may limit adaptability in the face of errors. To address these challenges, a custom wrapper is proposed that operates on top of Terraform, a leading Infrastructure-as-Code (IaC) tool. This wrapper enables diverse cloud deployments through a customized configuration file, simplifying the process of auditing, configuring, and securing various deployments. Practical experiments confirm the seamless deployment of infrastructure across various cloud providers, notably AWS and Azure. Specifically, the successful deployment of a Linux VM on both platforms showcases the adaptability of the approach to diverse cloud environments. The solution also maintains an easy learning curve, ensuring accessibility and industry-friendliness for users managing infrastructure across different cloud providers.
