It provides cloud-compatible APIs for development, testing, CI/CD, and integration workflows without requiring access to real cloud infrastructure. ## About Hosting CloudTwin This deployment runs CloudTwin as a single Railway service. CloudTwin exposes emulated AWS, Azure, and GCP APIs through one application endpoint and includes a web dashboard for inspecting emulator state and activity. The dashboard is available at: ```text /dashboard ``` CloudTwin can persist emulator state using SQLite stored on a Railway Volume. No PostgreSQL, Redis, MySQL, MongoDB, or external database is required for standard usage. ## Common Use Cases * Develop applications against AWS-compatible APIs * Test Azure service integrations * Test GCP-compatible workflows * Run integration tests without accessing production cloud resources * Build multi-cloud development environments * Test SDK configuration and cloud abstraction layers * Validate applications that support multiple cloud providers * Run CI/CD workflows against disposable cloud APIs * Inspect emulator activity through a web dashboard * Create reusable cloud testing environments for development teams ## Dependencies for CloudTwin Hosting This deployment requires: * CloudTwin container image * Railway networking * A Railway Volume for persistent SQLite storage * AWS, Azure, or GCP-compatible SDKs and clients CloudTwin does not require: * PostgreSQL * Redis * MySQL * MongoDB * A real AWS account * A real Azure subscription * A real Google Cloud project * Production cloud credentials ## Supported Cloud Providers CloudTwin provides emulated APIs across multiple cloud ecosystems. ### AWS Supported AWS-oriented services may include: * Amazon S3 * Amazon SQS * Amazon SNS * Amazon SES * DynamoDB * Lambda * Secrets Manager * Bedrock simulation ### Azure Supported Azure-oriented services may include: * Blob Storage * Queue Storage * Service Bus * Event Grid * Key Vault * Functions ### Google Cloud Supported GCP-oriented services may include: * Cloud Storage * Pub/Sub * Firestore * Cloud Tasks * Secret Manager * Functions API compatibility can vary by service and CloudTwin version, so advanced workloads should be validated against the specific emulator behavior they depend on. ## Networking CloudTwin uses a single application port: ```text 4793 ``` Railway automatically provides the `PORT` value for the deployed service. CloudTwin listens on that Railway-assigned port and binds to all network interfaces. Generate a Railway public domain for the service. The resulting endpoint will look similar to: ```text https://your-cloudtwin.up.railway.app ``` The same domain is used for: * Cloud API requests * Web dashboard access This single-port design makes CloudTwin simpler to expose publicly than emulators that require a separate port for each service. ## Accessing the Dashboard Open: ```text https://your-cloudtwin.up.railway.app/dashboard ``` The dashboard can be used to inspect supported emulator resources and activity. Depending on the enabled services and CloudTwin version, the dashboard may provide views for: * Service status * Recent events * AWS resources * Azure resources * GCP resources * S3 buckets and objects * SQS queues * SNS topics * SES messages * Emulator event history * Bedrock simulation or playground features The root domain is primarily used as the CloudTwin API endpoint. Use `/dashboard` when you want the browser-based interface. ## Persistent Storage Add a Railway Volume and mount it at: ```text /data ``` CloudTwin stores its SQLite database on the mounted volume at: ```text /data/cloudtwin.db ``` Using persistent storage allows supported emulator resources to survive container restarts and redeployments. No external database is required. ## Service Architecture ```text Application / SDK │ │ AWS / Azure / GCP APIs ▼ CloudTwin Railway PORT │ ├── AWS APIs ├── Azure APIs ├── GCP APIs ├── /dashboard │ ▼ /data/cloudtwin.db │ ▼ Railway Volume ``` ## Connecting Applications Applications can configure their cloud SDKs or clients to use the CloudTwin Railway endpoint instead of real cloud provider endpoints. Public endpoint: ```text https://your-cloudtwin.up.railway.app ``` Applications running inside the same Railway project can alternatively use Railway private networking. For a service named `cloudtwin`: ```text http://cloudtwin.railway.internal:${{PORT}} ``` Use the endpoint configuration supported by the specific AWS, Azure, or GCP SDK used by your application. ## Public and Private Access For applications inside the same Railway project, private networking is recommended whenever possible. Example: ```text http://cloudtwin.railway.internal:${{PORT}} ``` For applications outside Railway, use the generated public HTTPS domain. Because CloudTwin routes multiple cloud APIs through the same service, external clients do not require a separate public Railway domain for every emulated provider. ## Persistence Modes CloudTwin can be used with persistent or ephemeral state. ### SQLite Mode SQLite mode is recommended for this Railway deployment. CloudTwin stores emulator state in the SQLite database located on the Railway Volume: ```text /data/cloudtwin.db ``` Use this mode when emulator resources should survive supported restarts and redeployments. ### Memory Mode CloudTwin may also support ephemeral in-memory operation. In-memory state should be treated as disposable and will not survive service restarts. For a Railway template intended to provide a reusable development environment, persistent SQLite storage is recommended. ## Important Notes * CloudTwin is intended for development, testing, CI, and integration workflows. * It is not a production replacement for AWS, Azure, or Google Cloud. * CloudTwin emulates selected APIs rather than the complete functionality of each cloud provider. * API behavior may differ from real cloud services. * The web dashboard is available at `/dashboard`. * Cloud APIs and the dashboard share the same Railway-assigned application port. * SQLite persistence can be stored on a Railway Volume mounted at `/data`. * No PostgreSQL, Redis, MySQL, or MongoDB service is required. * Real AWS, Azure, or GCP credentials are not required for standard emulator usage. * Applications may require explicit endpoint configuration in their cloud SDKs. * Advanced or provider-specific workflows should be validated before relying on emulator behavior. ## Why Deploy CloudTwin on Railway? Railway provides a managed platform for running CloudTwin without requiring users to maintain dedicated servers or multiple local cloud emulators. Deploying CloudTwin on Railway provides a shared multi-cloud development environment for AWS, Azure, and GCP-compatible workflows with a built-in dashboard and persistent SQLite storage. It is useful for application development, automated testing, CI pipelines, SDK integration testing, and multi-cloud experimentation without connecting to production cloud resources. ## Similar templates - [Rocky Linux](https://railway.com/deploy/rocky-linux) — Hosted Rocky Linux 9 workspace with SSH and persistent storage. 🚀 - [Foundry Virtual Tabletop](https://railway.com/deploy/X5tR6G) — A Self-Hosted & Modern Roleplaying Platform - [Letta Code Remote](https://railway.com/deploy/letta-code-remote) — Run a Letta Code agent 24/7.
