+## Deployments
+
+Deployment is the step of the software delivery process when your application gets deployed to its
+final, target infrastructure.
+
+### Deploy with Auto DevOps
+
+[Auto DevOps](autodevops/index.md) is an automated CI/CD-based workflow that supports the entire software
+supply chain: build, test, lint, package, deploy, secure, and monitor applications using GitLab CI/CD.
+It provides a set of ready-to-use templates that serve the vast majority of use cases.
+
+[Auto Deploy](autodevops/stages.md#auto-deploy) is the DevOps stage dedicated to software
+deployment using GitLab CI/CD.
+
+### Deploy applications to Kubernetes clusters
+
+With the extensive integration between GitLab and Kubernetes, you can safely deploy your applications
+to Kubernetes clusters using the [GitLab Agent](../user/clusters/agent/install/index.md).
+
+#### GitOps deployments **(PREMIUM)**
+
+With the [GitLab Agent](../user/clusters/agent/install/index.md), you can perform pull-based
+deployments using Kubernetes manifests. This provides a scalable, secure, and cloud-native
+approach to manage Kubernetes deployments.
+
+#### Deploy to Kubernetes with the CI/CD Tunnel
+
+With the [GitLab Agent](../user/clusters/agent/install/index.md), you can perform push-based
+deployments with the [CI/CD Tunnel](../user/clusters/agent/ci_cd_tunnel.md). It provides
+a secure and reliable connection between GitLab and your Kubernetes cluster.
+
+### Deploy to AWS with GitLab CI/CD
+
+GitLab provides Docker images that you can use to run AWS commands from GitLab CI/CD, and a template to
+facilitate [deployment to AWS](../ci/cloud_deployment). Moreover, Auto Deploy has built-in support
+for EC2 and ECS deployments.
+
+### General software deployment with GitLab CI/CD
+
+You can use GitLab CI/CD to target any type of infrastructure accessible by the GitLab Runner.
+[User and pre-defined environment variables](../ci/variables/index.md) and CI/CD templates
+support setting up a vast number of deployment strategies.
+
+## Environments
+
+To keep track of your deployments and gain insights into your infrastructure, we recommend
+connecting them to [a GitLab Environment](../ci/environments/index.md).
+
+## Releases
+
+Use GitLab [Releases](../user/project/releases/index.md) to plan, build, and deliver your applications.
+
+### Feature flags
+
+Use [feature flags](../operations/feature_flags.md) to control and strategically roullout application deployments.
