Evidence-Gated Migration to Vast.ai

Overview

Separate portability from cutover. First identify source-provider dependencies, then prove immutable image, storage, networking, secrets, GPU, and output behavior on a disposable Vast.ai canary before moving production work.

Prerequisites

• Source inventory covering images, accelerators, storage, network, identity, schedules, and cost
• Acceptance thresholds for correctness, throughput, latency, recovery, and total spend
• Versioned data/checkpoint transfer, dual-run or drain plan, and rollback owner

Instructions

Step 1: Freeze source truth

Record source release, image digest, GPU profile, command, secrets interfaces, ports, persistent data, checkpoints, SLOs, and representative outputs.

Step 2: Map Vast.ai equivalents
