Failoverilla

Failoverilla is a software platform designed to automate failover and disaster recovery for distributed applications and services. It provides a framework for detecting component or site failures and executing controlled failovers to standby resources, with policy-driven decision making, fast recovery, and auditable operations.

Core components include a central control plane that runs health checks and orchestrates workflows, lightweight agents installed on monitored hosts or containers, and a messaging broker for event propagation. The system supports multi-region deployments, active-passive and active-active configurations, and pluggable backends for metrics, data replication, DNS or load balancers, and storage.

Key features encompass health monitoring across services, automatic failover and switchover, failback workflows, data replication coordination, and policy-based routing. Failoverilla offers integration with Kubernetes, configuration management tools such as Terraform and Ansible, and cloud provider APIs. It can trigger DNS or load balancer reconfigurations, promote standby databases, and coordinate safeguards like quorum checks and time synchronization. An auditable history of decisions and actions supports compliance and post-incident analysis.

Deployment considerations include the need for defined recovery objectives and network reliability, as well as potential complexity and latency implications. Proper implementation requires accurate health signals, consistent clocks across sites, robust data replication, and careful avoidance of split-brain scenarios. Availability of support and licensing can vary by distribution if the project is community-driven or vendor-provided.
