+# Defang Deployment Modes
+
+Defang provides three deployment modes: development, staging, and production. These modes allow you to balance cost and resiliency according to your needs.
+
+* **Development**: This mode is used for development and testing purposes. It typically involves less stringent resource allocations and may include debugging tools and verbose logging to aid in development.
+* **Staging**: This mode serves as a pre-production environment where applications are tested in conditions that closely mimic production. It helps in identifying issues that might not be apparent in the development environment.
+* **Production**: This mode is used for live deployments. It involves optimized configurations for performance, security, and reliability. Resource allocations are typically higher, and debugging tools are minimized to ensure stability.
+
+## Deployment Mode Comparison
+
+| Feature | Development | Staging | Production |
+|-|-|-|-|
+| Build Resources | Builds will be run with 2x vCPUs | Builds will be run with 2x vCPUs | Builds will be run with 4x vCPUs |
+| Databases | Defang will provision resources optimized for burstable memory | | Defang will provision resources optimized for production |
+| Static Resources | | | Defang will provision a CDN |
+| Deployment | Previous deployments will be spun down before new deployments are spun up. | | Rolling updates will be used to deploy new versions. Defang will gradually replace services while maintaining at least the original number of replicas. |
+| Logging | Logs retained for 1 day to save costs. | | Logs retained for 30 days for compliance. |
+| Networking | | | Defang will provision a NAT gateway. |
+| DNS | Defang will provision shorter TTLs | | Defang will provision longer TTLs |

 ### Can I bring my own AWS or other cloud account?
 
-- Yes! Please check out the [Defang BYOC](./concepts/defang-byoc.md) documentation for more information.
+- 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 whatever other resources exist in the cloud account you are using as a [Defang BYOC](./concepts/defang-byoc.md) Provider.
+- 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?
+### 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?
+
+- 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?
 
-- 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).
+- 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).

 ### What is Defang?
 
 Defang is a radically simpler way for developers to develop, deploy, and debug their cloud applications. Defang enables you to easily author cloud application in any language, build and deploy to the cloud with a single command, and iterate quickly with AI-assisted tooling.

 - Defang can automatically build and deploy your project with a single command.
     - If you’re new to Defang, you can try deploying to the [Defang Playground](./concepts/defang-playground.md), a hosted environment to learn to use Defang with non-production workloads.
     - Once you’re ready, you can [deploy](./concepts/deployments.md) it to your own cloud account - we call this [Defang BYOC](./concepts/defang-byoc.md). Defang takes care of all the heavy lifting such as configuring networking, security, [observability](./concepts/observability.md) and all the other details that usually slow down the average cloud developer.
