Today, we’re announcing the next generation of AWS Resilience Hub with a significantly expanded experience that brings together a new application model, dependency discovery assessment, generative AI-powered failure mode analysis, modular resilience policies, and organization-wide reporting.

Organizations running hundreds of applications share a common challenge: availability is a top concern, yet there is no consistent way to set resilience goals, measure progress, or prove compliance across a portfolio. Teams set different standards, use different tools, and struggle to exchange information about whether applications actually meet expectations.

The next generation of AWS Resilience Hub changes this by giving Site Reliability Engineers (SREs) and development teams a structured way to align on resilience policy expectations, help application teams achieve them, and demonstrate compliance through testing. With integration into AWS Organizations, teams can now evaluate resilience at scale, identify failure modes, discover hidden dependencies, and report on progress across the enterprise.

The next generation of Resilience Hub walks you through your resilience journey and to help you there are the following concepts built into it.

• Resilience policy: You can define your resilience expectations through modular, composable requirements. Rather than choosing a single rigid policy type, you construct policies by selecting the requirements that matter to your application, such as service level objective (SLO), multi-AZ and multi-Region disaster recovery, and data recovery requirements.
• Business-level understanding: You can use new application modeling through critical end-user paths that map directly to business outcomes. Systems represent a business application, user journeys describe critical business paths, and services are the deployable units comprising AWS resources, code, and observability. Resilience Hub automatically discovers and maps them into a topology showing how resources connect.
• AI failure mode assessments: You can run generative AI-powered assessments that analyze your services against your defined resilience policies, AWS Well-Architected best practices, and the AWS Resilience Analysis Framework. These assessments identify potential failure modes and provide actionable recommendations.
• Dependency discovery assessment: You can automatically discover AWS services, internal endpoints, and third-party endpoints that your services depend on. This dependency assessment uses DNS query log analysis to identify dependencies you may not know about—including unexpected cross-region calls or critical third-party dependencies.

The next generation of AWS Resilience Hub in action

To get started, you configure a resilience policy, set up your first system and service, run a failure mode assessment, review the results, and implement the findings.

Before you begin, you should set up the invoker IAM role, which grants Resilience Hub read-only access to your AWS resources, cross-account roles (if not using AWS Organizations), or service-linked roles (SLRs) with AWS Organizations. Resilience Hub also integrates with AWS Organizations to enable organization-wide resilience management from a single delegated administrator account. This eliminates the need to log in to individual accounts to assess resilience posture across your enterprise. To learn more, visit For prerequisite details in the AWS Resilience Hub User Guide.

To configure a resilience policy, choose Create policy in the Policies menu through the AWS Resilience Hub console. Enter a policy name, description, and choose resilience requirements. For example, you can create a reusable policy for multi-Region disaster recovery used in financial applications—including 99.95% availability SLO, 15-minutes RTO, 5-minutes RPO for multi-Region disaster recovery, and disaster recovery approach that aligns with your RTO and RPO requirements.

If you choose data recovery requirements, you can define the data recovery time objective for restoring from backups for each service associated with this policy.

To create your first system representing your business application, choose Create a system in the Systems menu. Optionally, you can enable AWS Organizations account access for this system.

Now you can create a service that represents a deployable unit, like one of your microservices, and associate it with your system, and tell Resilience Hub where to find your resources. Enter a service name, for example, stock-exchange-service, choose your resilience policy and invoker AWS IAM role name. You can choose service Regions, service resources such as your resource tags, AWS CloudFormation stack, Terraform state file location, or Amazon EKS cluster and namespace.

When you enable dependency discovery for this service, AWS examines your VPC query logs for the VPCs associated with the resources in your service. You can disable this feature anytime from the dependency discovery settings in the service details page.

Now, you can run your first assessment with the service creation complete and a policy applied. Choose Run failure mode assessment in your service page and wait for the assessment to complete.

During the assessment, Resilience Hub assumes your invoker role, reads resources from your configured input sources, identifies parent-child relationships, queries the application topology service to map connections between resources, and builds a topology showing data flow, containment, and permissions.

By choosing Service topology, you can see service resources grouped by service functions in the graph, table, or JSON format.

By choosing Failure mode guidance, you can add assertions used to guide the agents while performing the failure mode assessment. Assertions are either generated by the agent or added by users. You can update them to improve assessment accuracy.

Once the assessment is complete, you can review findings and recommendations in the Assessment tab of your service page. Each finding tells you what the failure mode is, why it matters for your architecture, how to fix it, and which policy requirement it relates to.

You can choose Mark as resolved to implement the recommendation or Mark as irrelevant if the finding doesn’t apply to your use case.

If you’re an existing Resilience Hub customer, Resilience Hub provides migration APIs to simplify the transition of your previous applications. These APIs convert your previous assessment policies to new resilience policies, map your previous applications to the new model, such as multiple related applications to one system with multiple services.

For more information about new features, visit the AWS Resilience Hub User Guide.

Now available

The next generation of AWS Resilience Hub is now generally available in AWS commercial Regions where Resilience Hub is available. For Regional availability and the future roadmap, visit the AWS Capabilities by Region.

Resilience Hub uses a new service-based pricing model. Pricing includes two failure mode assessments per month for services, and optionally automated dependency assessment. You can try AWS Resilience Hub free. For pricing details, visit the AWS Resilience Hub pricing page.

Give the new AWS Resilience Hub a try in the Resilience Hub console and send feedback to AWS re:Post for Resilience Hub or through your usual AWS Support contacts.

Organizations are increasingly expanding their Kubernetes footprint by deploying microservices to incrementally innovate and deliver business value faster. This growth places increased reliance on the network, giving platform teams exponentially complex challenges in monitoring network performance and traffic patterns in EKS. As a result, organizations struggle to maintain operational efficiency as their container environments scale, often delaying application delivery and increasing operational costs.

Today, I’m excited to announce Container Network Observability in Amazon Elastic Kubernetes Service (Amazon EKS), a comprehensive set of network observability features in Amazon EKS that you can use to better measure your network performance in your system and dynamically visualize the landscape and behavior of network traffic in EKS.

Here’s a quick look at Container Network Observability in Amazon EKS:

Container Network Observability in EKS addresses observability challenges by providing enhanced visibility of workload traffic. It offers performance insights into network flows within the cluster and those with cluster-external destinations. This makes your EKS cluster network environment more observable while providing built-in capabilities for more precise troubleshooting and investigative efforts.

Getting started with Container Network Observability in EKS

I can enable this new feature for a new or existing EKS cluster. For a new EKS cluster, during the Configure observability setup, I navigate to the Configure network observability section. Here, I select Edit container network observability. I can see there are three included features: Service map, Flow table, and Performance metric endpoint, which are enabled by Amazon CloudWatch Network Flow Monitor.

On the next page, I need to install the AWS Network Flow Monitor Agent.

After it’s enabled, I can navigate to my EKS cluster and select Monitor cluster.

This will bring me to my cluster observability dashboard. Then, I select the Network tab.

Comprehensive observability features

Container Network Observability in EKS provides several key features, including performance metrics, service map, and flow table with three views: AWS service view, cluster view, and external view.

With Performance metrics, you can now scrape network-related system metrics for pods and worker nodes directly from the Network Flow Monitor agent and send them to your preferred monitoring destination. Available metrics include ingress/egress flow counts, packet counts, bytes transferred, and various allowance exceeded counters for bandwidth, packets per second, and connection tracking limits. The following screenshot shows an example of how you can use Amazon Managed Grafana to visualize the performance metrics scraped using Prometheus.

With the Service map feature, you can dynamically visualize intercommunication between workloads in your cluster, making it straightforward to understand your application topology with a quick look. The service map helps you quickly identify performance issues by highlighting key metrics such as retransmissions, retransmission timeouts, and data transferred for network flows between communicating pods.

Let me show you how this works with a sample e-commerce application. The service map provides both high-level and detailed views of your microservices architecture. In this e-commerce example, we can see three core microservices working together: the GraphQL service acts as an API gateway, orchestrating requests between the frontend and backend services.

When a customer browses products or places an order, the GraphQL service coordinates communication with both the products service (for catalog data, pricing, and inventory) and the orders service (for order processing and management). This architecture allows each service to scale independently while maintaining clear separation of concerns.

For deeper troubleshooting, you can expand the view to see individual pod instances and their communication patterns. The detailed view reveals the complexity of microservices communication. Here, you can see multiple pod instances for each service and the network of connections between them.

This granular visibility is crucial for identifying issues like uneven load distribution, pod-to-pod communication bottlenecks, or when specific pod instances are experiencing higher latency. For example, if one GraphQL pod is making disproportionately more calls to a particular products pod, you can quickly spot this pattern and investigate potential causes.

Use the Flow table to monitor the top talkers across Kubernetes workloads in your cluster from three different perspectives, each providing unique insights into your network traffic patterns.

Flow table – Monitor the top talkers across Kubernetes workloads in your cluster from three different perspectives, each providing unique insights into your network traffic patterns:

• AWS service view shows which workloads generate the most traffic to Amazon Web Services (AWS) services such as Amazon DynamoDB and Amazon Simple Storage Service (Amazon S3), so you can optimize data access patterns and identify potential cost optimization opportunities.
• The Cluster view reveals the heaviest communicators within your cluster (east-west traffic), which means you can spot chatty microservices that might benefit from optimization or colocation strategies
• External viewidentifies workloads with the highest traffic to destinations outside AWS (internet or on premises), which is useful for security monitoring and bandwidth management.

The flow table provides detailed metrics and filtering capabilities to analyze network traffic patterns. In this example, we can see the flow table displaying cluster view traffic between our e-commerce services. The table shows that the orders pod is communicating with multiple products pods, transferring amounts of data. This pattern suggests the orders service is making frequent product lookups during order processing.

The filtering capabilities are useful for troubleshooting, for example, to focus on traffic from a specific orders pod. This granular filtering helps you quickly isolate communication patterns when investigating performance issues. For instance, if customers are experiencing slow checkout times, you can filter to see if the orders service is making too many calls to the products service, or if there are network bottlenecks between specific pod instances.
