Practical Virtualization for Learners
Practical Virtualization for Learners
Get Started with Cloud Computing and Tools - VirtualBox, Vagrant, Wireshark, AWS, Azure, GCP, Ansible, Docker, and PostgreSQL
About the Book
This book starts with virtual machines in VirtualBox on a local computer (Windows 10, macOS or Linux) and briefly covers those in the cloud (AWS, Azure or GCP). It will help the reader get started with cloud computing and have a feel in a short period of time through hands-on activities. Hopefully, the reader will familiarize herself/himself with some important concepts (virtualization, virtual machines, hypervisors, automation, containers and networking) and tools (VirtualBox, Vagrant, Ansible, Wireshark, Docker and PostgreSQL).
