<ul><li>Resource dependencies and lifecycle management are critical concepts in cloud computing, DevOps, and infrastructure-as-code (IaC).</li><li>Implicit dependencies occur when a resource's lifecycle depends on another resource without explicitly defining the dependency. Tools like Terraform automatically infer implicit dependencies based on resource configuration.</li><li>Explicit dependencies are manually defined to ensure resources are created or destroyed in a specific order. This is useful when implicit dependencies are insufficient or more granular control is required.</li><li>Lifecycle rules define how resources are managed during their creation, update, and destruction. These rules include retain policies, ignore changes, and replacement strategies.</li><li>The create/destroy order ensures resources are created in the correct sequence and destroyed in the reverse order to maintain dependencies and system stability.</li><li>Prevention of destruction involves protecting resources from accidental deletion using tools, policies, or configurations.</li></ul>
