Free DevOps Course - 45 days

#devopscourse

Agenda

  • Introduction to Virtual Machines (VMs)
  • Benefits of Virtualization in DevOps
  • Types of Virtualization Technologies
  • Setting Up a Virtual Machine Environment

Key Points

  1. Introduction to Virtual Machines (VMs)

    • VMs are software-based simulations of physical hardware, allowing multiple operating systems to run on a single physical machine.
    • They provide isolation and encapsulation, making them valuable for various use cases.

  2. Benefits of Virtualization in DevOps

    • VMs enable the creation of reproducible and isolated development and testing environments.
    • They aid in resource optimization, allowing better utilization of hardware resources.
    • VM snapshots facilitate easy backup and recovery.

  3. Types of Virtualization Technologies

    • There are various virtualization technologies, including hardware virtualization (e.g., VMware, Hyper-V) and container-based virtualization (e.g., Docker).
    • Each has its use cases and advantages.

  4. Setting Up a Virtual Machine Environment

    • Steps to create a VM:
      • Choose a virtualization platform (e.g., VirtualBox, VMware, or cloud-based solutions like AWS EC2).
      • Define VM specifications (CPU, RAM, storage).
      • Install an operating system on the VM.
      • Configure networking and connectivity.
      • Snapshot the VM for future use.

Homework

  • Research and provide a brief comparison between hardware virtualization and container-based virtualization. Highlight their key differences and use cases.

Additional Resources

Remember to actively participate in discussions and ask questions during the course to enhance your understanding of virtualization and its role in DevOps.
