AZ and resilience
Improve the resilience of your services
To minimise your vulnerability to major incidents and make your services highly available, it is crucial to consider deploying your services within an infrastructure with several availability zones (Availability Zones or AZs). This is why we are offering a 3-AZ Region in Paris.
- 3 independent availability zones
- 30 km distance between AZs
- An independent low latency network
Why deploy your infrastructure in our 3-AZ Region in Paris?
By deploying your workloads across several AZs, you can make your key use cases more available and resilient.
Virtualisation and containerisation
Optimise the performance of your clusters as you deploy your virtual machines on a large scale across our three availability zones. You can, as a result, improve the performance and availability of your services.
Database replication
Deploy your databases (MySQL, PostgreSQL, Redis, Kafka, Cassandra, etc.) across several availability zones to make them highly available and resilient.
Storage Distribution
Replicating your storage solutions on dedicated servers gives you resilient environments for your data, or your customer’s data.
Key differences between a 1-AZ Region and a 3-AZ Region
3-AZ Region
Description
The 3-AZ Region comprises three availability zones (AZs), is completely independent, and offers very high resilience and ultra low latency between AZs.
Specifications
- Number of datacentres per AZ: 1 for our 3-AZ service in Paris.
- A private network specific to this infrastructure.
- Compatible Bare Metal services: Scale or High Grade dedicated servers
- Other available services: Additional IP
1-AZ Region
Description
The 1-AZ Region comprises only one availability zone. It has a fully redundant power supply and network. The storage space within this region is divided between several datacentres. OVHcloud operates several 1-AZ Regions globally (Roubaix, Gravelines, Frankfurt, Beauharnois, etc.). These regions could transition from 1-AZ to 3-AZ over time.
Specifications
- Number of datacentres per region, which varies by region.
- Standard redundant network.
- Compatible Bare Metal services — the entire range, adapted to the region’s specificities.
Our global infrastructure
With a global presence and a total of 43 datacentres, our infrastructure allows you to deploy your services as close as possible to your customers.
Our Regions
Our Regions in Europe, the United States and Asia‑Pacific offer optimal coverage for your cloud projects.

Your questions answered
Will other Regions benefit from multiple AZs in the future?
Yes, all our customers around the world need this type of solution. As we implement our roadmap, we will communicate on planned deployments of multiple-AZ services.
What services can be deployed within the 3-AZ Region in Paris?
Only the second-generation Scale and High Grade dedicated servers are presently compatible with this service. Our Public Cloud storage solutions will be the next to support this service.
What is the difference between a Region and an AZ?
A region refers to a physical location in which one or more availability zones are located.
An availability zone (AZ) is made up of one or more physically separate datacentres within the same region. This is aimed at ensuring higher availability and fault tolerance for cloud services and applications. Each AZ has its own independent and redundant power, cooling and network infrastructure. As a result, there is no risk of the entire region becoming unavailable if an infrastructure failure (electrical, network, etc.) occurs. While they offer higher availability, AZs are also specifically designed to maintain high-performance connectivity (i.e., the optimal latency) between AZs within the same region.
