# As Europe Eyes Move From US Hyperscalers, IONOS Dismisses Scalability Worries - The World Has Changed; EU Hosting CTO Says Not Considering Alternatives Is Negligent

Welcome to the era of self-hosted solutions! With growing concerns about data privacy and sovereignty in Europe, many organizations are shifting their focus from US hyperscalers towards local providers that offer robust self-hosted infrastructure. In this post, we delve into setting up a self-hosted environment using IONOS as our provider, addressing scalability concerns often cited by those hesitant to make the switch.

Prerequisites

• An account with IONOS
• Access to a Linux server (Ubuntu 20.04 LTS is used in this example)
• Basic understanding of Linux command line and DevOps principles
• A shell client (e.g., SSH, MobaXterm) to access your server

Solution

We’ll walk through a multi-step process for setting up a self-hosted infrastructure using Docker Compose and Kubernetes on your IONOS server:

1. Install Docker and Compose

First, ensure that the required software packages are installed. We will use docker-ce version 5.0.8 and docker-compose version 1.27.4 in this example.

sudo apt update
sudo apt install docker-ce=5.0.8 docker-ce-cli containerd.io curl gnupg lsb-release
curl -L "https://raw.githubusercontent.com/docker/compose-filev2-examples/master/compose-filev2.yml" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

2. Create Docker Compose Configuration File

Create a docker-compose.yml file in the desired working directory and configure your services as needed:

version: '3'
services:
  app1:
    image: your_app_image
    ports:
      - "80:80"
    environment:
      - APP_ENV=production

  db:
    image: postgres:12.4-alpine
    volumes:
      - ./data/db:/var/lib/postgresql/data

3. Run Docker Compose

Now, start your services using Docker Compose:

docker-compose up -d

4. Install Kubernetes (Optional)

If you require a more advanced orchestration solution, consider installing Kubernetes on your server:

1. Add the kubectl package repository to your system:

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add
echo "deb http://apt.kubeflow.org/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubectl.list
sudo apt update

1. Install Kubectl:

sudo apt install kubectl

1. Create a kubeconfig file for your cluster, if needed:

kubectl config set-cluster my-cluster --server=https://api.<your_kubernetes_master_ip>:6443
kubectl config set-context my-context --cluster=my-cluster --user=kubelet --namespace=my-namespace
kubectl config use-context my-context

Troubleshooting

Check the status of your services with:

• docker ps for Docker Compose
• kubectl get pods for Kubernetes

Conclusion

Transitioning from US hyperscalers to self-hosted solutions, such as IONOS, is no longer a daunting task. With the power of DevOps tools like Docker Compose and Kubernetes, you can create a flexible, scalable infrastructure that aligns with your organization’s data privacy concerns. Embracing open-source technologies not only enhances your technical skillset but also empowers you to control your digital infrastructure more effectively.
