12 Cloud and Cloud Integration with SUSE

  • .

Cloud computing is a model for providing computing services (such as servers, storage, networking, software) over the internet. Cloud environments can be:

  • Private Cloud: Private cloud infrastructure, such as OpenStack.

  • Public Cloud: Public cloud services, such as AWS, Azure, and Google Cloud.

  • Hybrid Cloud: A combination of private and public clouds.

SUSE in the Cloud

SUSE Linux Enterprise Server (SLES) is designed to support cloud environments. SUSE provides compatibility with popular cloud platforms such as:

  • OpenStack: An open-source cloud platform for building private clouds.

  • AWS: A public cloud infrastructure that provides a variety of services.

  • Azure: Microsoft's cloud platform for applications and services.

SUSE's Cloud Advantage

  1. Optimal Performance: SLES is optimized to run workloads in cloud environments.

  2. Multi-Cloud Support: SUSE supports integration with multiple cloud providers.

  3. Cost Efficiency: Flexible licensing to support cloud models.

  4. Security: Features such as AppArmor and patch management for data security.

Using SUSE in Cloud Environments

SUSE in OpenStack

OpenStack is an open-source platform for building private clouds.

  • SUSE OpenStack Cloud Installation
  1. Add the OpenStack repository:
sudo zypper addrepo -f https://download.suse.com/openstack SUSE-OpenStack
  1. Install the OpenStack packages:
sudo zypper install openstack
  1. Configure OpenStack services such as Nova (compute), Neutron (networking), and Swift (storage).

SUSE on AWS

AWS provides SUSE Linux Enterprise Server on AWS Marketplace, which allows the use of SLES with ready-to-use configurations.

  • Steps to Use SLES on AWS

  1. Log in to the AWS Management Console.

  2. Search for SUSE Linux Enterprise Server in the AWS Marketplace.

  3. Select the SLES version and EC2 instance.

  4. Configure instance parameters such as instance type, networking, and storage.

  5. Launch an instance and access it using SSH.

SUSE on Azure

SUSE has deep integration with Microsoft Azure, including the SUSE Linux Enterprise Server for SAP Applications option.

  • SLES Deployment Steps on Azure

  1. Log in to the Azure Portal.

  2. Search for SUSE Linux Enterprise Server in the Azure Marketplace.

  3. Select a VM size and data center location.

  4. Configure network, disk, and other parameters.

  5. Launch the VM and access it via SSH.

Using SUSE Manager for Infrastructure Management

SUSE Manager is an infrastructure management tool designed to manage physical, virtual, and cloud servers from a single console.

Key Features of SUSE Manager

  1. Configuration Management: Manage server configurations using SaltStack.

  2. Patch Management: Ensure all systems have the latest security patches.

  3. System Monitor: Track system performance and status.

  4. Multi-Cloud Management: Manage systems in hybrid or multi-cloud environments.

SUSE Manager Installation

  1. Add the SUSE Manager repository:
sudo zypper addrepo -f https://download.suse.com/manager SUSE-Manager
  1. Install packages:
sudo zypper install susemanager
  1. Configure SUSE Manager through the installation wizard.

Using SUSE Manager

  1. Add Systems to SUSE Manager:
  • Install the Salt agent on the client system:
sudo zypper install salt-minion
  1. Patch Management:
  • Apply patches to all systems:
sudo zypper patch
  1. Monitoring: Use the SUSE Manager dashboard to monitor system status.

Container Management with Kubernetes on SUSE

Kubernetes is a container orchestration platform used to manage container-based applications.

SUSE and Kubernetes

SUSE provides Rancher, a Kubernetes management platform for managing Kubernetes clusters across multiple environments.

Installing Rancher

  1. Install Docker:
sudo zypper install docker
sudo systemctl start docker
sudo systemctl enable docker
  1. Run Rancher using Docker:
sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher
  1. Access Rancher via browser:
https://< IP-ADDRESS>

Kubernetes Cluster Management

  1. Create a Cluster:
  • Use Rancher to create a new Kubernetes cluster or import an existing one.
  1. Manage Pods:
  • Use Rancher or kubectl to manage pods:
kubectl get pods
  1. Application Deployment:

  • Create a YAML file for deployment:

    apiVersion: apps/v1
kind: Deployment
metadata:
      name: nginx-deployment
      spec:
        replicas: 3
        selector:
          matchLabels:
            app: nginx
        template:
          metadata:
            labels:
              app: nginx
          spec:
            containers:
            - name: nginx
              image: nginx:latest
              ports:
              - containerPort: 80

  • Apply deployment:

    kubectl apply -f deployment.yaml
