Automated Multi-Cloud Infrastructure Provisioning and Management Using Terraform and DevOps Practices

Computer Science and Engineering

Cloud computing has transformed IT infrastructure management by enabling scalable and flexible deployments. However, manually provisioning and managing cloud resources can be time-consuming, error-prone, and inefficient. This project explores Infrastructure as Code (IaC) using Terraform to automate cloud infrastructure provisioning across AWS, Azure, and Google Cloud. By leveraging Terraform’s declarative configuration, the project ensures consistent, efficient, and scalable infrastructure deployment while minimizing manual intervention. The implementation involves defining modular Terraform scripts to provision key cloud resources, including compute instances (EC2, Azure VMs, GCP Compute), networking (VPCs, security groups, firewalls), storage (S3, Azure Blob, GCP Cloud Storage), and databases (AWS RDS, Azure SQL, GCP Cloud SQL). The project integrates Kubernetes (EKS, AKS, GKE) for containerized workloads, incorporating service mesh technologies like Istio and Linkerd to enhance secure microservices communication. Automated monitoring and logging are implemented using AWS CloudWatch, Azure Monitor, GCP Stackdriver, and centralized ELK (Elasticsearch, Logstash, Kibana) stack. Policy enforcement is strengthened with Open Policy Agent (OPA) for access control and compliance validation. To enhance security, the project includes role-based access control (RBAC), encryption mechanisms, and HashiCorp Vault for secret management. Additionally, CI/CD pipelines are automated using GitHub Actions, ArgoCD, and FluxCD to enable continuous infrastructure deployment. Multi-cloud cluster management is supported through Rancher and OpenShift, ensuring seamless Kubernetes orchestration. The project also integrates AWS Fargate to optimize cost by running Kubernetes workloads in a serverless environment. Cost-efficient strategies such as AWS Spot Instances and FinOps monitoring provide insights for better resource allocation. Automated drift detection and policy validation ensure infrastructure consistency over time. By automating cloud infrastructure provisioning, monitoring, security, and compliance, this project demonstrates the effectiveness of Terraform and DevOps automation, significantly reducing manual errors, improving collaboration, and accelerating cloud deployments across hybrid and multi-cloud environments.
