# Single binary
> Run one service adapter process with a simple, explicit operating boundary.
The **single binary** deployment runs one service adapter process. It is the smallest useful operating shape: one endpoint, one process to supervise and one configuration to manage.
## When to use it
Use a single binary for local development, evaluation, low-volume workloads or a service where process-level redundancy is provided by the surrounding platform. “Single” describes the adapter process, not the durability of your data.
## What you operate
* The adapter binary and its runtime configuration.
* The endpoint and network path used by callers.
* Runtime credentials and access to destination services.
* Backend data, backups and recovery procedures.
For production, place the process under a supervisor and exercise restart and backend-failure recovery before sending traffic.
## Move to a cluster
When one process is no longer enough for availability or throughput, keep the same service configuration and move to [Cluster](./cluster). Validate shared state, connection limits and rollout behavior before switching traffic.
