Frequently Asked Questions (FAQ)
Answers to common questions regarding architecture, RAM migration, persistent storage, and network security.
Frequently Asked Questions
1. Are running processes restarted during host migration events?
No. The microsrv orchestrator executes background live RAM and CPU state migration. Active applications continue executing without process restarts or dropping in-memory state.
2. Is data on block storage preserved during host reclamation?
Yes. All block volumes (NVMe Volumes) are backed by distributed, fault-tolerant storage arrays. When a VM moves to a new host, volumes attach seamlessly with zero data loss.
3. Do VM instances require a public IP address to function?
No. Outbound requests (package updates, external APIs) go through outbound NAT. Inbound connections are accepted by the SSH gateway (msrv.space) and the HTTPS gateway (<vm>.msrv.space). To join the VPC from a laptop, use the WireGuard gateway.
4. Are microsrv instances suitable for production database workloads?
Yes. Thanks to volume data replication and socket-level state preservation, database engines (PostgreSQL, MySQL, Redis) retain established client connection pools and maintain strict data integrity.
