Bastionhost:Purchase an instance

Last Updated:Mar 31, 2026

Purchase a bastion host before using Bastionhost to manage and audit access to your server assets. Choose a region, edition, and plan that match your infrastructure scale and O&M requirements.

Important

Enable Auto-renewal during purchase to avoid service interruption when the instance expires. For pricing details, see Billing.

Prerequisites

Before you begin, ensure that you have:

  • (Recommended) Identified the region where your Elastic Compute Service (ECS) instances are deployed — place your bastion host in the same region to enable internal network access

Choose an edition

If you need...Choose
O&M on 1,000+ assets, database O&M, automatic password rotation for Linux servers, webpage-based O&M, or hybrid cloud O&M via the network domain featureEnterprise Edition
Basic O&M and audit capabilities on a smaller asset countBasic Edition

For a full feature comparison, see Functions and features.

Enterprise Edition runs in dual-engine mode: both engines operate simultaneously to improve O&M efficiency, and the bastion host automatically switches between engines if a single point of failure (SPOF) occurs.

Basic Edition runs in single-engine mode and supports O&M and audit operations.
