Description: The GCP Deployment Manager is a service that allows developers and system administrators to specify all the resources needed for their applications in a declarative format. This means that instead of manually configuring each component of the infrastructure, users can programmatically define their environment using configuration files. This approach, known as ‘Infrastructure as Code’, facilitates automation and infrastructure management, enabling teams to deploy and scale applications more efficiently. Key features include the ability to version configurations, integration with CI/CD (Continuous Integration/Continuous Deployment) tools, and the ability to audit and track changes in the infrastructure. The relevance of this manager lies in its ability to reduce human errors, improve the reproducibility of environments, and accelerate application delivery time, which is crucial in a world where agility and efficiency are fundamental to business success.
