About
The High Availability mind map template provides a technical framework for designing resilient IT systems, covering 69 nodes of architectural strategies. It serves as a comprehensive High Availability cheat sheet for engineers to evaluate service recovery time objectives (RTO) and service level agreements (SLA). The content specifically addresses the trade-offs between synchronous and asynchronous replication, detailing how to manage 'Regional persistent disks' and 'HA Database' configurations. By mapping out the relationship between primary and standby VM instances, this High Availability template helps teams calculate the cost implications of maintaining hot standbys versus on-demand backup VMs. It includes specific technical guidance on 'Live Migration' and 'Failover' mechanisms to ensure data integrity during zonal outages.
Terms and ConditionsWhen to use this template
DevOps Teams and Site Reliability Engineers (SREs)
Conducting a disaster recovery audit for existing database infrastructure
IT Managers and Technical Leads
Preparing technical documentation for stakeholder approval on infrastructure budget and resilience
How to use this template
Step 1
Import the template file
Open the .xmind file in Xmind to view the full 69-node structure across the High Availability sheets.
Step 2
Customize your HA parameters
Replace the generic SLA and RTO values with your specific project requirements in the Overview branch.
Step 3
Map your infrastructure components
Use the HA Database and Regional persistent disks branches to document your specific VM and storage configurations.
Frequently asked questions
This template focuses on the architectural design of resilient cloud systems. It covers storage options like regional persistent disks, database redundancy, and the operational procedures for failover and live migration to minimize downtime during zonal or regional outages.
The template includes specific nodes on determining service recovery time objectives (RTO). It explains how force-attaching regional persistent disks can achieve an RTO in minutes and compares the recovery speeds of hot standby VMs versus starting instances on demand.
Yes, the 'HA Database' branch is specifically designed for this. it outlines the configuration for primary and standby VM instances, including the use of managed instance groups and the separation of boot disks from data disks for better fault tolerance.
Absolutely. You can download the .xmind file and customize the 69 nodes to match your specific cloud provider's terminology, adjust the cost calculations, or add your own internal SLA requirements and health check protocols.
