Purpose of Assessment

This journal reflects on a series of structured lab tasks completed throughout the BRG-ISEA unit, focusing on the real-world application of server environment concepts in both Linux and cloud systems. Each lab involved practical, hands-on experience with system operations, automation scripting, cloud provisioning, cost modelling, DNS configuration, and security hardening. The learning journey culminated with a recorded video demonstration, allowing for both technical execution and reflective analysis of decisions, challenges, best practices and lessons learned.

Scope of Assessment

Reflect on all activities completed across the 4-day intensive mode. These include Linux setup, cloud deployment, scripting, permissions, DNS configuration, SSL certificates, a consulting session, and one self-selected additional server service.

You must reflect on the full range of activities across the 4-day intensive schedule, including:

• Discovery and observations
• Problems you solved
• Tools you used
• Insights gained
• Relevance to industry roles (e.g., System Admin, DevOps, IT consultant)

MU BRG-ISEA: Introduction to Server Environments and Architectures

Grading Criteria

BRG-ISEA Lab Activities

Session 1a: Setting Up Linux

Create a GitHub account and start documenting progress.

• → Go to https://github.com and sign up for a new account.
• → Create a new repository (e.g., BRG-27-labs).
• → Clone the repository to your local machine using Git.
• → Add a README.md and start documenting each lab you complete.

Lab: Obtaining Linux on your PC – Install Ubuntu using VirtualBox.

• → Download Ubuntu ISO from the official website.
• → Install VirtualBox and create a new virtual machine.
• → Configure VM settings (e.g., 4GB RAM, 20GB disk).
• → Mount ISO and install Ubuntu through guided installer.

Lab: Familiarity with Ubuntu Linux – Basic command line navigation and utilities.

• → Practice using `pwd`, `ls`, `cd`, `mkdir`, and `touch`.
• → Understand directory structure (`/etc`, `/var`, `/home`).
• → Use `man` to explore Linux manual pages.

Session 1b: Exploring Linux

Lab: Linux Services – Understanding and managing background services.

• → List services using `systemctl list-units –type=service`.
• → Start/stop services with `sudo systemctl start|stop [service]`.
• → Check status of services using `sudo systemctl status`.

Lab: Linux Permissions – Explore and apply file and directory permissions.

• → Use `ls -l` to view permissions.
• → Change permissions using `chmod` (e.g., `chmod 755 file.sh`).
• → Change ownership using `chown user:group file.txt`.

Lab: Searching Filesystems – Use commands like `find` and `grep`.

• → Use `find /path -name ‘filename’` to locate files.
• → Use `grep -r ‘search-term’ /path/` to search content.             

Session 2a: Total Cost of Ownership

Lab: Total Cost of Ownership – Apply TCO concepts in practical comparison.

• → Compare cloud vs on-prem cost (hardware, software, licensing).
• → Use Excel or Google Sheets to document monthly and yearly costs.
• → Calculate break-even point, ROI and 3-year projections.
• → Compare TCO across cloud providers
