Introduction
Overview
Nexaa’s Serverless Containers service provides a fast and flexible way to run your applications without worrying about managing servers, clusters, or infrastructure. Whether you're deploying REST APIs, scheduled jobs, microservices, or automation tools — serverless containers help you focus on code, not complexity.
Containers are provisioned and scaled automatically. You define the runtime environment, provide a container image, and Nexaa takes care of the rest — including execution, load balancing, availability, networking, and billing.
Note
Nexaa does not build Docker images.
Users must provide Docker images hosted in an external registry.
We support both public and private registries — for private registries, ensure valid credentials with permission to pull the image.
See the Container Registry Configuration page for details.
Key Concepts
Stateless by Design
Each container is ephemeral and stateless. That means no data is stored between runs unless you explicitly connect to a database or persistent storage.
Execution Modes
- Always-On: Services that run continuously
- Job-Based: Containers triggered based on a schedule
Comparison
| Feature | Always-On | Jobs |
|---|---|---|
| Lifecycle | Runs continuously | Executes once per trigger |
| Scheduling | Always available | Cron-based execution |
| Use Cases | APIs, workers, long-running task | Scripts, batch jobs, automation |
| Networking | Accepts ingress traffic | Can reach other services |
| Public domain | Link your domain name | Executed in the background |
Deployment Simplicity
You deploy using container images from public or private registries. Define environment variables, resources, and secrets — and you're ready to launch.
Namespace Isolation
Containers run inside Namespaces, which isolate traffic, logs, and configurations. This structure makes it easy to separate environments (e.g., dev, staging, production).
