Knovvu platform is architected to anticipate, absorb, and recover from failures. This ensures that customers remain unaffected, even when components fail. The following sections outline how resiliency is implemented across infrastructure and software levels.
Infrastructure Resiliency
Multi–Availability Zone Deployments
The Knovvu platform leverages AWS’s regional architecture, which consists of multiple Availability Zones (AZs). Each AZ contains one or more physically isolated data centers, with redundant power, networking, and connectivity.
Every Knovvu deployment within an AWS Region operates across multiple AZs in an active/active/active configuration. Incoming traffic is distributed across application instances running in each zone.
If an entire Availability Zone becomes unavailable, AWS load balancing automatically routes user requests to healthy instances in the remaining zones - ensuring uninterrupted service.
Highly Durable and Available AWS Managed Services
In addition to multi-AZ compute deployments, Knovvu platform takes advantage of AWS managed services that provide built-in durability and availability:
- Amazon S3 automatically replicates objects across multiple AZs. Even if one AZ experiences a failure, S3 continues serving data from the remaining zones without any configuration required.
- Amazon RDS provides multi-AZ database failover for continued database availability.
- Amazon EKS (managed Kubernetes) keeps Kubernetes control plane operations resilient across AZs.
- Application Load Balancers (ALB) distribute traffic efficiently with failover between Availability Zones.
These managed services reduce operational complexity while providing industry-leading durability.
Software Resiliency
Self-Healing Containers with Kubernetes
Knovvu platform uses Kubernetes to ensure applications remain healthy and operational. While multi-AZ architecture protects against data center-level failures, Kubernetes handles failures at the server or node level. If a server hosting a microservice becomes unavailable, Kubernetes automatically reschedules and starts that microservice on another healthy server, ensuring continuity without manual intervention.
Redundant and Stateless Microservices
Each Knovvu microservice is deployed in multiple instances (at least two) to guarantee fault tolerance. Even if one instance becomes unhealthy or crashes, traffic continues to flow to the healthy instances.
Kubernetes continuously monitors services using startup, liveness, and readiness probes. If an instance becomes unhealthy:
- Kubernetes restarts the service automatically.
- Traffic is not routed to the unhealthy instance.
- Other instances continue serving requests without interruption.
This ensures seamless operation during most failure scenarios.
Operational Resiliency
Real-Time Monitoring and Alerting
A comprehensive monitoring and alerting system is in place to track the health of the entire platform. Metrics, logs, and traces are monitored in real time. If anomalies or errors occur, proactive alerts enable teams to act quickly and prevent outages.
Runbooks for Incident Management
For critical components, the Knovvu platform maintains detailed runbooks - step-by-step operational guides used during incident response. These ensure teams respond consistently and effectively in rare cases where manual intervention is required.
Software Quality and Reliability
Automated End-to-End Integration Testing
To guarantee software reliability, the Knovvu platform incorporates extensive automated testing. End-to-end integration tests simulate real user behavior and validate interactions across:
- UI
- Backend
- Databases
- Networking layers
A dedicated integration test pipeline deploys the entire solution from scratch and executes these tests daily for both development and release branches. No software changes are released unless 100% of tests pass, ensuring maximum reliability.
Automated Load Testing
The platform also performs regular automated load testing to simulate high-traffic conditions. These tests run in a dedicated AWS account that mirrors production (without customer data). This setup ensures:
- Tests are repeatable
- Scenarios are consistent
- High-load performance remains predictable
The combination of cloud-native infrastructure, Kubernetes orchestration, automated testing, and operational excellence practices ensures that the Knovvu platform delivers a highly resilient service to customers.
