+# Frequently Asked Questions (FAQ)
+
+## Deployment and Infrastructure
+### Which cloud/region is the app being deployed to?
+
+- In the [Defang Playground](../concepts/defang-playground.md), the app is deployed to AWS `us-west-2`. In the [Defang BYOC](../concepts/defang-byoc.md) model, the region is determined by your [Defang BYOC Provider](/docs/category/providers) settings.
+
+### Can I bring my own AWS or other cloud account?
+
+- Yes! Defang makes it easy to deploy your application to your own cloud account. Please check out the [Defang BYOC](../concepts/defang-byoc.md) documentation for more information.
+
+### On AWS, can I deploy to services such as EC2, EKS, or Lambda?
+
+- The current release includes support for containers only, deployed to ECS. We are still exploring how to support additional execution models such as VMs and functions-as-a-service. However, using our Pulumi provider, it is possible to combine Defang services with other native AWS resources.
+
+### Can I access AWS storage services such as S3 or database services such as RDS? How?
+
+- Yes! You can access AWS services in the AWS Dashboard as you normally would when you are [deploying to your AWS account](../providers/aws) using Defang. In fact, you can access whatever other resources exist in the cloud account you are using for [Defang BYOC](../concepts/defang-byoc.md).
+
+### Do you plan to support other clouds?
+
+- While we currently support [AWS](../concepts/defang-byoc#aws) for production and [DigitalOcean](../concepts/defang-byoc#digitalocean) in preview, we plan to support other clouds in future releases, such as [GCP](../providers/gcp.md) and [Azure](../providers/azure.md).
+
+## Deployment Process
+
+### Can I run production apps with Defang?
+
+- 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).
+
+### 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?
+
+- 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.
+
+## Troubleshooting
+
+### I'm having trouble running the binary on my Mac. What should I do?
+
+- MacOS users will need to allow the binary to run due to security settings:
+    1. Attempt to run the binary. You'll see a security prompt preventing you from running it.
+    2. Go to System Preferences > Privacy & Security > General.
+    3. In the 'Allow applications downloaded from:' section, you should see a message about Defang being blocked. Click 'Open Anyway'.
+    4. Alternatively, select the option "App Store and identified developers" to allow all applications from the App Store and identified developers to run.
+
+### I'm getting a warning/error. What does it mean?
+- See the Common Warnings and Errors page.
