Scaling and AutoPilot

Fransys offers two approaches for managing your cluster capacity: AutoPilot mode (automatic) and Manual mode. You can switch between them at any time via the cluster configuration.

AutoPilot mode​

AutoPilot is the recommended scaling mode. Once activated, Fransys automatically adjusts your cluster resources based on load:

  • Scale up — Adding nodes when demand increases (traffic spikes, new block deployments)
  • Scale down — Removing nodes when load decreases (to reduce costs)

Configuration​

In AutoPilot mode, the only parameter to define is the maximum monthly budget (in euros). Fransys optimizes the cluster composition within this envelope:

  • Automatic selection of the most suitable node types
  • Intelligent workload distribution
  • Respect of the defined budget ceiling

When to use AutoPilot​

  • You're getting started on Fransys and don't want to size manually
  • Your load is variable or unpredictable
  • You want to optimize the cost/performance ratio without intervention

Manual mode​

Manual mode gives you full control over your cluster composition. You define the node pools yourself: how many nodes, of what type (CPU, RAM).

Node pools​

A node pool is a group of nodes sharing the same type (hardware configuration). You can have multiple pools in the same cluster to mix different machine types.

For each pool, you choose:

  • The type — Number of CPUs (shared or dedicated), amount of RAM
  • The number of nodes in the pool

When to use Manual mode​

  • You have specific sizing requirements (compliance, benchmarks)
  • You want to control exactly the allocated resources
  • You have a stable and predictable load

Modify scaling on an existing cluster​

From the cluster list, click the ⋮ menu then Edit config to:

  • Switch between AutoPilot and Manual modes
  • Adjust the maximum budget (AutoPilot)
  • Add, modify, or remove node pools (Manual)

Changes are applied progressively without service interruption.

tip

You can start with AutoPilot mode and switch to Manual mode at any time if your needs change — and vice versa. No data is lost when changing modes.
