-### Do you plan to support other clouds?
+### Can I run production apps with Defang?
 
-- While we currently support AWS as a [Defang BYOC](./concepts/defang-byoc.md) Provider, we plan to support other clouds in future releases, such as [Azure](./providers/azure.md) and [GCP](./providers/gcp.md).
+- Yes! Defang makes it easy to deploy your app on production-ready infrastructure in your own cloud account. For example, you can deploy your app to AWS with `defang up --provider=aws --mode=production`. Check out your preferred cloud provider on [Defang BYOC](./concepts/defang-byoc.md).
 
-### Can I run production apps with Defang?
+### Does Defang support blue/green deployments?
+
+- Defang does not currently support Blue/Green deploys, but it does support rolling updates with the `production` deployment mode. `defang up --mode=production`.
+
+### Does Defang support rolling deployments?
+
+- Yes! Defang supports rolling updates with the `production` deployment mode. `defang up --mode=production`.
+
+### Can I cancel a deployment once it has started?
+
+- No. Once a deployment has started, it cannot be canceled. However, you can always deploy a new version of your app which will replace the current deployment.
+
+### Will deploying a new version of my app cause downtime?
 
-- The [Defang Playground](./concepts/defang-playground.md) is meant for testing and trial purposes only. Deployment of productions apps with [Defang BYOC](./concepts/defang-byoc.md) is not yet supported and disallowed by the [Terms of Service](https://defang.io/terms-service.html). If you are interested in running production apps, please [contact us](https://defang.io/#Contact-us).
+- If you have deployed your application with the `--mode=production` flag, Defang will use the _production_ deployment mode. This mode will provision your app with multiple replicas and will perform a rolling update to ensure zero downtime. If you use another deployment mode, you may experience downtime during the deployment, as defang will not provision multiple replicas to save cost.
+
+### Can I deploy multiple services at once?
+
+- Yes! You can deploy multiple services at once by defining them in a single compose.yaml file. When you run `defang compose up`, Defang will deploy all the services defined in the file at once.
+
+### Can I deploy a service that depends on another service?
+
+- Defang does not currently support service dependencies. All services will be deployed simultaneously. Defang will however run multiple healthchecks before marking a service as healthy and spinning down any previously deployed services when using the `production` deployment mode.
+
+### Do you plan to support other clouds?
+
+- While we currently support [AWS](./concepts/defang-byoc#aws) and [Digital Ocean](./concepts/defang-byoc#digitalocean), we plan to support other clouds in future releases, such [GCP](./providers/gcp.md) and [Azure](./providers/azure.md).
