Discover Your Application's True Recovery Capabilities with AWS Resilience Hub
This document is a technical article aimed at IT professionals, business stakeholders, and cloud architects seeking to understand and improve their application's disaster recovery capabilities using AWS Resilience Hub.
This introduces AWS Resilience Hub as a solution to a common organizational challenge — the inability to clearly define (RPO) and (RTO) for applications. It guides through how the service discovers, assesses, and validates application resilience against business requirements.
Many organizations struggle to provide a definitive answer to a fundamental question about their disaster recovery strategy:
"What are your application's actual RPO and RTO capabilities?"
Surprisingly, many teams struggle to provide a definitive answer. The challenge isn't a lack of technical expertise—it's that these metrics require cross-functional alignment between IT, business stakeholders, and leadership to truly understand the impact of downtime on your operations.
Two Critical Questions That Shape Your Resilience Strategy
Before designing any resilience architecture, you need clarity on two fundamental questions:
1. Recovery Objectives
- RPO (Recovery Point Objective): How much data can you afford to lose?
- RTO (Recovery Time Objective): How quickly must your application be back online?

2. Business Impact
- What does each hour of downtime cost (approx. $ value) your business?
- What's the reputational damage beyond financial loss?
These answers directly influence your technical decisions, budget allocation, and ultimately, your ability to maintain customer trust during disruptions.
What We'll Cover in This Article
In this article, we'll focus on the first question and explore how AWS Resilience Hub can help you:
- Assess - Current RPO/RTO capabilities of existing applications
- Identify - Gaps between business requirements and actual resilience
- Validate - Improvements through controlled chaos engineering
- Build - Confidence to recover from unknown failures
What is AWS Resilience Hub?
AWS Resilience Hub is a centralized service that discovers, validates, and tracks application resilience across your AWS infrastructure. Unlike traditional DR planning, it continuously assesses applications against your specified targets.
How AWS Resilience Hub Helps
AWS Resilience Hub plays a vital role in enhancing organizational resilience by discovering previously unknown resilience SLAs.
1. Application Discovery and Assessment
AWS Resilience Hub begins by discovering your application components across your AWS infrastructure.
Automatic Resource Discovery
Resources Analysed:
- CloudFormation stacks or Terraform stacks
- AWS Services Catalogue AppRegistry
- AWS Resource Groups
Architecture Analysis
- Multi-AZ deployments: Current redundancy patterns
- Backup configurations: Frequency and retention policies
- Cross-region setups: Geographic distribution analysis
- Service dependencies: Critical path identification
RTO/RPO Validation
AWS Resilience Hub validates recovery time (RTO) and recovery point (RPO) targets against your current architecture, helping you understand whether your existing setup meets your business requirements.
Actionable Recommendations
The service provides specific recommendations to improve application resiliency, including suggestions for:
- Architectural changes
- AWS service configurations
- High-level cost to implement
2. Discovering RPO/RTO of Existing Applications
When you onboard an existing application to AWS Resilience Hub, the service performs a comprehensive analysis of your infrastructure components:
- Multi-service Architecture: Supports a wide range of AWS services and architectures, allowing assessment of complex, distributed applications
- Redundancy Patterns: Evaluates existing redundancy configurations, fault isolation mechanisms, and multi-region architectures
- Application-Level Resilience: Assesses application-level resilience patterns that impact overall recovery capabilities
As an outcome, it provides a detailed assessment report including an overview, RPO/RTO of application and infrastructure, along with resilience and operational recommendations.
3. Resilience Policy Definition
AWS Resilience Hub provides an out-of-the-box list of suggested resilience policies to choose from, or you can define your own policy.

These policies help you align with your business objectives. The table below provides guidance on choosing the right policy tier:
| Data Sensitivity | Recommended RPO | Policy Tier |
|---|---|---|
| Financial transactions / Critical, real-time data | < 1 hour | Mission Critical |
| Customer data, operational records | 1 - 4 hours | Critical |
| Configuration, user-generated content | 4 - 12 hours | Important |
| Reports, analytics, logs | 12 - 24 hours | Core Services |
| Archive data, backups | 1 - 7 days | Non-Essential |
4. Comprehensive Assessment Results
Once you add/publish your application to Resilience Hub, you can schedule or manually run assessments. The assessment report describes your existing:
- RPO/RTO: What your existing infrastructure can deliver based on configured backup frequencies, replication settings, and recovery procedures
- Gap Analysis: Where your current design falls short of your target objectives
- Compliance Score: An overall resilience score for your application
- Component-Level Details: Specific insights for each infrastructure component
Example Assessment Findings
The below example shows an assessment result with a defined policy of 4 hours RTO and 1 hour RPO:

Key Findings
| Metric | Target | Actual |
|---|---|---|
| RPO | 1 hour | 1 Day |
| RTO | 4 hours | 1 hour |
Issues Identified:
- Backups occur every 24 hours (RPO impact)
- Actionable Recommendations with Cost Estimation
One of the most powerful features of AWS Resilience Hub is its ability to provide specific, actionable recommendations along with cost implications.

Types of Recommendations
- Create AWS Backup plans with 1-hour backup frequency
Cost Transparency
For each recommendation, AWS Resilience Hub provides:
- Implementation Cost: One-time setup expenses
- Ongoing Operational Cost: Monthly recurring costs
Conclusion
AWS Resilience Hub helps you discover the actual recovery capabilities of your applications, often revealing gaps between business requirements and infrastructure reality.
By leveraging AWS Resilience Hub, organizations can:
- 🔍 Empower Business Users with clear visibility into application resilience posture and concrete improvement pathways
