Scaling out means adding more instances or nodes of a resource (horizontal scaling) to distribute workload across multiple machines.     What is Infrastructure as Code ( IaC ), and why is it important in DevOps and cloud environments?   Infrastructure as Code ( IaC ) is the practice of managing and provisioning cloud infrastructure using machine-readable configuration files, instead of manual setup. Tools like Terraform allow you to define infrastructure declaratively, automate deployments, and reuse configurations. IaC provides benefits such as consistent environments, version control, faster provisioning, and reduces human error. Features like state locking in Terraform help prevent concurrent changes that could corrupt the infrastructure state. ...
