They provide a preconfigured secure environment with necessary virtual network components, storage, and compute resources needed to deploy applications quickly. Landing zones follow best practices for security, compliance, architecture etc. so applications can be spun up faster. Different landing zones may exist for different types of workloads - for example, a landing zone optimized for web applications vs. batch processing jobs. Landing zones enable governance and access control for who can provision resources and spin up applications. They have automated workflows for provisioning and deployment using infrastructure-as-code tools like Terraform. Landing zones are modular and allow different application environments to be created - dev, test, staging, production etc. They integrate with CI/CD pipelines for automated testing and deployment of applications. Built-in monitoring and logging capabilities are included for observability after deployment.
