FAQ
What is a 3-AZ (Multi-AZ) region and how does it compare to a single-AZ cloud deployment?
A 3-AZ (multi-Availability Zone) region consists of three physically separate Availability Zones (AZs) within a single legal and network region. Each AZ is isolated to prevent single points of failure, enabling high availability and business continuity.
What happens if one Availability Zone fails?
In a 3-AZ deployment, workloads designed for resilience will continue to operate normally. Regional services like Load Balancer, Object Storage, Managed Kubernetes Service Standard, and Managed Databases automatically route around the failure.
Which services support 3-AZ today?
Core services include Compute, Classic & High Speed Block Storage, Object Storage, Load Balancer, Managed Kubernetes Service Standard, Managed Databases, Gateway, Public IP, and Floating IP.
How much does 3-AZ cost and how does pricing compare to hyperscalers?
On average, pricing for 3-AZ compatible services is approximately 10% higher than single-AZ services. However, there are no inter-AZ traffic charges, and pricing remains transparent and predictable.
OVHcloud 3-AZ offers significantly lower TCO than most hyperscalers — up to 2x more cost-efficient for services like Object Storage, Block Volumes, or Managed Kubernetes.
No HA (High Availability) surcharges, no hidden fees, and predictable billing. For complex deployments, OVHcloud and its partners can provide tailored support through Professional Services.
What SLA does OVHcloud offer for 3-AZ Multi-AZ cloud services?
We guarantee 99.99% SLA on all regional services, including Object Storage, Load Balancer, Public IP, Managed Kubernetes Service Standard, and Managed Databases.
Do I need to redesign my application to use 3-AZ?
Not necessarily. Most applications can be migrated with minimal adjustments using Terraform, CI/CD pipelines, and regional services. VM workloads may require basic HA (High Availability) planning.
Can I run Kubernetes in 3-AZ?
Yes. Managed Kubernetes Service Standard supports node pools across multiple AZs, with full integration of regional block storage and a high availability control plane.
What about database high availability?
Managed Database Services support automatic failover across AZs. Self-managed options can use Object Storage or Block Storage replication mechanisms.
Is 3-AZ compatible with Terraform?
Absolutely. All 3-AZ capable services can be deployed and managed using Terraform, with example modules and documentation available.
Can I run Bare Metal in a 3-AZ setup?
Yes. Dedicated infrastructure can be deployed in separate AZs, with high availability implemented at the application level or through managed services.
Are 3-AZ regions sovereign?
Yes. The current 3-AZ region is hosted entirely within France. Future 3-AZ regions are planned across Europe, the Americas, and Asia, each within its respective legal and compliance framework.
What are the most common use cases for 3-AZ?
Unlike standard single-AZ setups, a 3-AZ (Multi-AZ) deployment ensures business continuity even if an entire Availability Zone fails. Customers migrating from AWS or GCP often search for Multi-AZ equivalence in OVHcloud — and that's exactly what our 3-AZ for Public Cloud delivers.
OVHcloud 3-AZ (Multi-AZ) deployments are tailored for uptime-critical workloads. They’re especially valuable for:
- SaaS vendors needing native high availability
- Enterprise applications requiring continuity by design
- Digital commerce platforms operating under peak-load pressure
- Healthcare and regulated sectors with strict compliance needs
- Smart infrastructure where fault tolerance and regional resilience are vital.
What should I monitor or prepare before moving to 3-AZ?
Review your architecture for single points of failure, ensure backup policies are in place, and validate deployment automation. Contact our architects or Professional Services team for guidance.
