How do you get your data closer to your business while navigating move to cloud complexity? How can you ensure better infrastructure performance for your customers worldwide? Discover OVHcloud Local Zones: a groundbreaking compute solution for you, your customers and partners’ global expansion.

In this blog post, you will learn how to navigate through cloud architectures challenges. Unlock a realm of opportunities to expand globally while acting locally. Find out how to enhance your business with closer-to-use cloud infrastructure.

From centralized data centers to local data

For years, the traditional cloud architecture relied on a few centralized data centers. This often lead to data residency issues and unsatisfying user experience due to latency. Now, with our global infrastructure deployment concept comes a new era. OVHcloud Local Zones shorten the long distances travel of your data. Ensuring localized owned management of your infrastructure. You can now have the power to choose wherever you want to host your data globally and how to protect the most sensitive ones locally. 

“Cross-border data transfers can have a huge positive impact on the economy by 2030 if we make the right decisions now.” – Hilary Mine, President of DIGITALEUROPE 

How to help your data navigate the right way with Local Zones

OVHcloud’s Local Zones extend the reach of its infrastructure to key urban hubs across several countries. Within the coming years, we will offer new infrastructure in 150 cities. These infrastructures simplify localization of sensitive data. On top of that, it improves application performance across the board, without imposing exorbitant costs or complexities on organizations. 

Three Ways Local Zones Help International Companies 

1. Store Data Locally: Operating in multiple countries often entails grappling with regulatory complexities. Local Zones enable businesses to store data within the same country. With a minimized latency, ensuring faster content delivery, and facilitating data localization and protection. 
2. Scale with Confidence: Locating data centers nearest to areas of high user demand is strategical. That’s why Local Zones allow companies to deploy at scale and expand their services seamlessly. All of this while maintaining reliability and freedom of choice. Always, at the best price performance ratio.
3. Improve User Experience: In an age where consumers demand lightning-fast responsiveness, Local Zones facilitate the hosting of services locally, resulting in lower latency and higher user satisfaction.

Expand Safely with Local Zones 

That’s right. It goes without saying that data residency and state-of-the-art computing are crucial. What’s more, reduced latency and international expansion make OVHcloud an indispensable partner for companies on the road to digital transformation. Especially if you’re looking to gain a competitive edge in the global marketplace.

Managed Rancher Services (MRS)

Managed Rancher Services (MRS), in Beta for now, is based on Rancher, an open-source container management platform, that simplifies the deployment and management of Kubernetes clusters. Managed Rancher Service by OVHcloud provides a powerful platform for orchestrating Kubernetes clusters seamlessly.

Find more information on our dedicated Managed Rancher Services page.

Note: The product is in Beta so you can try Managed Rancher Services for free!

Local Zones (LZ)

This year we also launched Local Zones. Local Zones are an extension of regions that bring OVHcloud services closer to specific locations, offering reduced latency and improved performances for applications.
Local Zones are strategically placed in proximity to areas with high user demand. Their main goal is to minimize the time it takes to transfer data between the user and the cloud, in order to make services faster and more responsive, and meet data residency requirements.

Find more information on our dedicated Local Zone page.

Note: Until 31 August 2024 you can try Local Zones for free!

Kubernetes on Compute instances

At OVHcloud we have a Managed Kubernetes Services solution but you can also deploy Kubernetes clusters on Compute Instances if you want to managed in your own your clusters.

Find more information on our dedicated Compute instances page.

Demo

In this demo we will:

• Create 5 compute instances (3 for the Kubernetes’s etcd + controlplane & 2 for workers) on a Local Zone
• Create a managed Rancher
• In Rancher, configure the instances to deploy into them a Kubernetes cluster (with k3s or RKE2, depending on your needs ans use cases)

Creating Compute instances

First, you have to log in to the OVHcloud Control Panel and open the Public Cloud section. Then access the Instances under the Compute section.

Click on the Create an instance button.

Choose a model (the type of an instance / the flavor, B3-8 for example, but you can choose another one, depending on your needs).

Choose a local zone (Marseille for example):

Choose a distribution (Ubuntu for example).

Select your SSH key (we have to log in our instances later).

Choose 5 as the number of instances to be created and change the name of the instance name (lz-kube for example).

Check the checkbox Public network (to have a pubic IP).

The instances will take several minutes to spawn.

Deploying a Managed Rancher

Still in the OVHcloud Control Panel, click on the Create a Managed Rancher Service button.

Fill a name (my_lz_rancher for example), choose the Standard plan, the recommended version then click on the Create a Managed Rancher Service button.
Rancher instances are pre-provisioned, so your instance will be created immediately.

In the list of existing Managed Rancher Service, click on your instance, then click on Generate access code button to generate the login and password to access to Rancher. Save the login and password and click on Go to Rancher button.

Copy/paste the password in password field and click on Log in with Local User button.

A new password will be generated, save it! Save the server URL too, check the End User License Agreement checkbox and click on the Continue button.

Configuring Rancher to deploy a Kubernetes cluster

Creating a cluster

In Rancher UI, click on the Create button and then on the Custom driver:

Fill a cluster name (lz-k3s for example).

In the Kubernetes version list, choose the latest version of the wanted OS. For this blog post we will choose the latest version of K3s, but for production needs we recommend RKE2 instead.

Then click on Create button.

Configuring the cluster

Note:
In Rancher when you configure a node, there are three roles that can be assigned to nodes: etcd, controlplane and worker.

There are some good practices:

• At least 3 nodes with the role etcd are needed to survive a loss of 1 node and have a minimum high availability configuration for etcd. 3 etcd nodes are generally sufficient for smaller and medium clusters, and 5 etcd nodes for large clusters.
• At least 2 nodes with the role controlplane for master component high availability.
• You can set both the etcd and controlplane roles for one instance.
• The worker role should not be used or added to nodes with the etcd or controlplane role.
• At least 2 nodes with the role worker for workload rescheduling upon node failure.

For the configuration of our etcd + control planes nodes, check only the etcd and control plane Nodes Roles:

And copy/paste the registration command in a file.
For the configuration of our worker nodes, uncheck the checkboxes and check only the Worker checkbox:

And copy/paste the registration command in a file.

In the OVHcloud Control Panel, click on the Instances button.

Fill the search box with the beginning of the name of our instances: lz-kube.

For the first three instances, pick the Public IP addresses and then in your local terminal connect you in ssh and copy/paste the first registration command (for etcd and control plane nodes):

$ ssh root@xxx.xxx.xxx.xxx
The authenticity of host 'xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx)' can't be established.
ED25519 key fingerprint is SHA256:dqsdqsdqsdqsd/dqsdqsdqsdqsdqsdqsdq.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

And for the last two instances, pick the Public IP addresses and then in your local terminal connect you in ssh and copy/paste the second registration command (for worker nodes):

$ ssh root@xxx.xxx.xxx.xxx
The authenticity of host 'xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx)' can't be established.

Wait until the cluster is in Active state.

Connecting to the cluster with kubectl CLI

In Rancher UI, click on the lz-k3s cluster.

Then click on the Download KubeConfig icon to download the kubeconfig file and save the path of kubeconfig in an environment variable:

$ export KUBE_CLUSTER=$(pwd)/lz_k3s.yml

Test the connexion to the Kubernetes:

$ kubectl --kubeconfig=$KUBE_CLUSTER cluster-info

List the nodes:

$ kubectl --kubeconfig=$KUBE_CLUSTER get no
