Enterprise Cassandra High Availability& Disaster Recovery

Our automated failover typically completes within 30-60 seconds with zero data loss. We use health monitoring and intelligent routing to detect failures and redirect traffic to healthy nodes immediately. The exact failover time depends on your consistency level settings and network latency between datacenters.

We implement quorum-based consistency levels (QUORUM, LOCAL_QUORUM), network partition detection, and proper datacenter awareness configuration. Our monitoring systems detect split-brain conditions and automatically resolve them using predefined resolution strategies. We also configure proper snitch settings and use NetworkTopologyStrategy for multi-datacenter deployments.

We support multi-region Cassandra deployments on AWS (across multiple availability zones and regions), Google Cloud Platform (multi-region and multi-zone), Microsoft Azure (geo-distributed regions), and hybrid cloud environments. Our solutions work with managed services like DataStax Astra and self-managed clusters. We can also implement Cassandra migrations between cloud providers.

We achieve RTO (Recovery Time Objective) of 5-15 minutes and RPO (Recovery Point Objective) of near-zero through continuous multi-datacenter replication, automated backups, and geo-distributed deployment. Our disaster recovery plans include automated failover procedures, validated recovery runbooks, and regular DR drills. We use NetworkTopologyStrategy with appropriate replication factors to ensure data is always available in multiple datacenters.

Yes, we implement comprehensive audit logging, encryption at rest and in transit (TLS/SSL), role-based access control (RBAC), and compliance monitoring. Our solutions meet SOC 2, HIPAA, PCI-DSS, and GDPR requirements with full audit trails. We provide detailed documentation, compliance reports, and work with your security team to ensure all regulatory requirements are met.

We use a combination of Prometheus for metrics collection, Grafana for visualization, DataStax OpsCenter for cluster management, and custom monitoring solutions. Our dashboards provide real-time visibility into cluster health, replication lag, node status, read/write latencies, and performance metrics with intelligent alerting. We also integrate with PagerDuty, Slack, and other incident management tools for rapid response.

We perform rolling upgrades with zero downtime using a phased approach. Each node is upgraded individually while maintaining quorum and replication. We validate each step with automated testing, monitor cluster health throughout the process, and provide rollback procedures if needed. Our upgrade process includes pre-upgrade validation, compatibility testing, and post-upgrade verification to ensure a smooth transition.
