Managed IaaS

Explore the UNIQCloud OpenStack services. A robust, open-source cloud platform providing scalable compute, storage, networking, and orchestration capabilities to build and manage your infrastructure.

High Availability & Resilience (Availability Zones)​

UNIQCloud is architected for maximum uptime and resilience using multiple Availability Zones (AZs) with local redundancy within a single Tier III certified data center.

Local Redundancy Zones

UNIQCloud provides three OpenStack Availability Zones (AZs) within a single data center in Valencia. Each AZ operates on independent rack infrastructure to deliver local redundancy, ensuring that a failure in one zone does not affect the others.

Physical Infrastructure

Hosted within a Tier III certified data center, UNIQCloud benefits from rack-level redundancy. This physical-level fault tolerance guarantees concurrent maintainability and continuous operations.

Resiliency & Failover Scenarios

Workload deployment is designed to span all three OpenStack Availability Zones to ensure maximum resilience. The platform is engineered to gracefully handle zone outages:

3 Zones Active

Normal Operations

Workloads span all three AZs. Full read-write capability is active with continuous replication.

1 Zone Outage

Normal Continuity

UNIQCloud withstands single-zone failures. Systems run normally while recovery is completed by UNICC personnel.

2 Zones Outage

Read-Only Access

The third zone remains operational in read-only mode to prevent data loss. Services remain accessible, but no new data can be written.

Workload Spanning

Design Best Practice

Distributing application workloads across all three Availability Zones is highly recommended to guarantee full high availability.
