  • Tool Focus: Kubernetes.

    • Timeframe: 4 to 6 weeks.

    • Key Concepts:

      • Architecture (master and worker nodes), key components (pods, services, deployments).

      • Resource management and scaling, networking model in Kubernetes.

9. Networking and Infrastructure Services

  • Importance: Managing services like reverse and forward proxies, load balancers.

  • Tool Focus: NGINX.

    • Timeframe: 3 to 4 weeks.

    • Key Concepts:

      • Setting up/configuring NGINX for reverse proxy and load balancing.

      • Caching strategies, configuring firewalls/security groups.

10. Configuration Management

  • Importance: Automating deployment/configuration/management of servers and applications.

  • Tool Focus: Ansible.

    • Timeframe: 3 to 4 weeks.

    • Key Concepts:

      • Writing playbooks, using roles/modules, managing variables/templates.

11. Infrastructure as Code (IaC)

    • Timeframe: 3 to 4 weeks.

    • Key Concepts:

      • Providers/resources, writing configuration files, using modules.

      • Advanced concepts (workspaces, remote state).

12. Monitoring and Logging

  • Importance: Tracking performance and health of applications/infrastructure.

  • Tool Focus: Prometheus and Grafana.

    • Timeframe: 3 to 4 weeks.

    • Key Concepts:

      • Architecture/data model of Prometheus, collecting metrics.

      • Writing queries, setting up alerts.
