Workflow orchestration / Nextmv DecisionOps alternative

A Nextmv alternative for the agent execution layer

Nextmv manages decision models, optimization runs, experiments and deployment. A run takes an application and input and returns results; a version retains executable code. Those contracts differ from a general-purpose agent computer with a writable system that returns across tasks.

When Nextmv DecisionOps fits

Nextmv fits routing, scheduling and other optimization systems needing solver integrations, decision-model management, experiments and controlled application versions. These are specialized product capabilities that a Linux sandbox does not supply automatically.

When to consider Sandbox0

Consider Sandbox0 for compatible Linux agents that prepare, build or orchestrate decision workflows and need a durable full writable RootFS, online growth and supported paused files. Retain required solvers, licenses, experiments and decision-service APIs.

Capabilities

Nextmv DecisionOps and Sandbox0: what persists?

Feature comparison with documentation and verification status

Online RootFS growth

On growth-enabled images, Sandbox0 automatically expands the writable RootFS as free space runs low, within a configured sparse logical ceiling up to 64 TiB. Agent processes keep running. Growth is enabled in the qualified Cloud region; confirm activation for other regions. Existing images and snapshots retain their captured storage geometry. The ceiling is logical capacity, not preallocated host disk.

Nextmv selects application runtimes, compute classes and run limits. Those controls and code versioning do not establish automatic online growth of a complete durable per-agent RootFS.

Files while compute is paused

Sandbox0's Files API reads persistent files without resuming compute. Filesystem-only pauses also permit edits; retained-memory pauses are read-only and reject mutations with 409. SSH, SFTP, file watching, and runtime-only mounts require running compute.

Versions retain code rather than the whole running machine

A Nextmv version references immutable executable code: source files for interpreted applications or a compiled binary. A run has its own input, options, status and output. Code versions and stored run results do not establish persistence of arbitrary runtime OS changes or process memory across executions.

Runtimes are selected for the optimization app

Apps declare a supported Docker-based runtime. The current catalog includes ARM64 compiled and Python environments and an AMD64 GPU-enabled cuOpt runtime. Check architecture and solver compatibility before moving a model; custom package and runtime requirements may need vendor support.

Execution credits describe time in a selected compute class

One credit corresponds to one standard-compute second; premium compute uses two credits per second. Current Innovator and Scale-up tables show 15-minute per-run limits and different daily run caps, while Premium is custom. Contact-us subscription terms and execution overages must be budgeted separately.

Pricing

Compare billing models, then price your workload

CPU allocation, memory, billing minimums, disk, plan fees, and supported workload differ. These meters are not equal-performance machine quotes. Confirm region, resource units, and included allowances before estimating a total.

Sandbox0

$0.015/GiB-hour compute (billed by the second at approximately $0.000004167/GiB-second), plus $0.02/GiB-month of retained incremental RootFS and memory checkpoint data. Shared base images and platform recovery retention are excluded; paused sandboxes accrue storage charges only.

Before migrating from Nextmv DecisionOps

  1. Inventory decision apps, input/output formats, solver licenses, architectures, version pinning, experiments and run limits.
  2. Keep required DecisionOps services or recreate them explicitly; migrate compatible Linux agent preparation and orchestration with verified tools and files.
  3. Validate optimization results and solver performance separately from agent system retention, RootFS growth, paused files and usage-credit costs.

Common questions

Is Sandbox0 a drop-in Nextmv DecisionOps replacement?

Evaluate API compatibility and product scope. These products serve different core workflows, so a change may require a different architecture.

Does keeping files also keep a running agent?

Filesystem state and volatile process state are separate. Sandbox0 requires explicit compatible memory checkpoints to preserve running processes; its default filesystem resume starts fresh processes.
