The servers were drowning in requests. The load balancer kept them alive.
Infrastructure as Code (IaC) makes this possible without touching a console. With IaC, you define your load balancer in code—version controlled, repeatable, and ready to deploy on demand. No manual clicks in a cloud dashboard. No guessing which settings you changed last week.
A load balancer in IaC takes raw traffic and directs it to healthy targets. It scales horizontally as traffic spikes. It removes failing nodes and keeps latency low. You can configure routing rules, SSL termination, cross-zone distribution, and health checks entirely in code. Using Terraform, Pulumi, or AWS CloudFormation, the definition becomes a blueprint. Every environment—dev, staging, prod—gets the exact same configuration.
