What Is High Availability?

High Availability (HA) refers to a system’s ability to remain operational and accessible without interruption, even during component failures or unexpected surges in demand. In an HA environment, systems are designed to minimize downtime and maintain continuous service so that users always have access to essential applications and services.

100% SLA Commitment

  • Service Level Agreement (SLA):
    An SLA is a formal contract that defines the expected level of service, typically measured by uptime.
  • Our 100% SLA Promise:
    WEDOS Protection is built on a global Anycast Infrastructure—WEDOS Global—comprising over 3,000 servers spread across numerous Points of Presence (POPs). If any server or POP requires maintenance or becomes overloaded, traffic is automatically and instantly rerouted to the next available, healthy node. This redundant, geographically distributed architecture enables us to confidently promise 100% service availability.

Key Components and Strategies for High Availability

  1. Global Anycast Network
    • Widespread Distribution:
      With over 3,000 servers located worldwide, our Anycast network ensures that user requests are always directed to the nearest or best-performing server.
    • Resilient Architecture:
      Traffic is distributed across multiple POPs, so if one location experiences issues, others seamlessly assume the load.
  2. Intelligent Load Balancing & Automated Failover
    • Dynamic Traffic Distribution:
      Advanced load balancing algorithms evenly distribute incoming requests across the network, preventing any single server from becoming a bottleneck.
    • Immediate Failover:
      Continuous real-time health checks and automated failover systems instantly detect and respond to any server or POP issues, rerouting traffic without interruption.
  3. Continuous Monitoring and AI-Driven Optimization
    • Real-Time Analytics:
      Constant monitoring of traffic patterns and server performance allows for proactive adjustments in resource allocation.
    • Adaptive Resource Management:
      AI-driven models help optimize routing and maintain maximum uptime, even during peak loads or unforeseen events.
  4. Proactive Maintenance and Security
    • Zero-Disruption Updates:
      The distributed nature of our infrastructure allows for routine maintenance on individual components without affecting overall service availability.
    • Global Threat Intelligence:
      Integrated security measures and proactive threat mitigation protect the infrastructure from cyberattacks that might otherwise cause downtime.

How WEDOS Protection Enhances High Availability

WEDOS Protection ensures continuous service through a streamlined combination of the above strategies:

  • Global Distribution:
    User requests are always routed to the optimal server via our extensive Anycast network.
  • Instantaneous Failover:
    Automated systems detect issues in real time and redirect traffic immediately, ensuring no noticeable downtime.
  • Optimized Performance:
    AI-driven analytics continuously refine traffic management, balancing load and preserving system integrity.
  • Uninterrupted Maintenance:
    The network’s redundancy allows us to perform updates or handle overloads without impacting service availability.

Conclusion

By leveraging a global Anycast infrastructure with over 3,000 servers, intelligent load balancing, automated failover, and continuous AI-driven monitoring, WEDOS Protection achieves a high level of service reliability. Our multi-layered approach enables us to offer a 100% SLA, ensuring a secure, resilient, and always-on digital presence for our customers—even in the face of maintenance, overload, or unexpected challenges.
