Strengths of self-hosted on Rollin
- Embeddings stay in Brazil (Tier III SP datacenter) — LGPD-friendly
- Dedicated AMD EPYC + NVMe RAID 1 hardware for ANN performance
- Automatic NF-e in BRL (essential for Brazilian entities to deduct)
- Predictable cost — US$ 17.98 to US$ 119.90/mo depending on VPS size
- You pick the engine (Qdrant, Weaviate, Milvus) by use case
- No vendor lock-in — embeddings exportable at any time
- 24/7 human Portuguese support for infrastructure questions
Weaknesses of self-hosted on Rollin
- You're responsible for engine updates (apt update, docker pull, restart)
- Horizontal scaling requires planning (manual sharding on Milvus, etc)
- Off-VPS backup is your responsibility (configure dump to external S3)
- No automatic auto-scaling — you upgrade the plan manually
- Team needs at least some Docker and Linux logs knowledge
