Availability & Trust
Your users' ability to log in is critical - it's the gateway to everything else in your application. Our architecture can keep your authentication system running even if individual components fail, helping maintain continuous access for your users.
How it works?
Our availability strategy combines simplicity and proven cloud architecture. Here's how: We deploy redundant components across two cloud regions, each containing:
- Reliable DNS
- Independent load balancers managing traffic distribution
- Secured application and sandbox instances in private subnets
- Replicated search and storage clusters for data availability
Our infrastructure is deployed across three availability zones within a region, with traffic redirecting to healthy zones during any outages. This multi-layered approach keeps your authentication system operational during infrastructure challenges. In the unlikely event of a complete regional outage, our system switches to another region to maintain service availability.
Our high-availability strategy
Our commitment to availability goes beyond infrastructure. Our strategy is built on three core principles:
Intelligent session management: We design user sessions to persist across any infrastructure changes, allowing seamless user experiences even during backend updates or failovers. Our architecture automatically scales to handle millions of concurrent sessions without performance degradation.
Priority-based architecture: Critical authentication functions take priority, with independent scaling and failover protocols maintaining the availability of core services even if non-essential features are impacted. Each component can scale independently, allowing us to handle sudden traffic spikes efficiently
Continuous evolution: Our engineering teams constantly monitor system performance, analyze scaling patterns, and implement improvements. This data-driven approach helps us anticipate capacity needs, automatically scale resources, and prevent potential issues before they impact your users
This comprehensive strategy combines technical architecture with operational excellence, delivering the reliability and scalability your growing applications depend on.
Continuous deployment with no downtime
Our platform evolves constantly and is designed for a zero-downtime deployment process. From simple documentation updates to major feature releases, Auth0 is designed to deploy multiple times daily without service interruptions. Our deployment cycle follows a rigorous process:
Release: Changes are carefully versioned and prepared for deployment
Build: Code is compiled and packaged in isolated environments
Deploy: Updates are rolled out gradually across our infrastructure
Test: Automated and manual testing validates each deployment
This continuous deployment pipeline means that whether we're optimizing performance, adding features, or updating documentation, your authentication service remains consistently available. Every change follows this proven process, allowing us to maintain reliability while continuously improving our platform.
