Syllabus

Introduction to Cloud Computing

In this module, we will cover the basics of cloud computing, its key advantages, and the foundational service models (IaaS, PaaS, SaaS). You will learn about the essential resources, virtual instances, and how cloud computing supports modern business operations.

Cloud Computing Service Models

In this module, we will dive deeper into the three primary cloud computing service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). We will examine how each model supports different types of workloads and compare their features.

Cloud Server Deployment on Linode

In this module, we will walk through the steps of setting up and managing a Linode cloud server. You'll learn how to secure your instance with SSH authentication, deploy virtual servers, and connect remotely using multiple methods. This hands-on guide will build your cloud server administration skills.

Linux Foundations

In this module, we will introduce Linux, its file system, and common administrative tasks. You will learn essential Linux commands, how to create and secure user accounts, and how to perform basic server configurations. This module is foundational for managing Linux-based cloud environments.

Web Server and Database Foundations

In this module, we will explore the essential components of web servers and databases. You’ll learn about web hosting options, key differences between NGINX and Apache, and how SQL and NoSQL databases operate. This knowledge is critical for anyone building and maintaining cloud-hosted applications.

LAMP Stack Installation and Configuration

In this module, we will guide you through installing and configuring a LAMP stack on an Ubuntu server, both through the command line and using the Linode Marketplace. You'll also learn to test PHP integration with MariaDB and remotely manage your server using Linode tools.

Foundations of Server Security

In this module, we will focus on server security fundamentals, including firewalls and SSH best practices. You’ll learn how to configure network firewalls, apply security rules, and protect server access, ensuring the integrity and safety of your cloud environments.

Server Scaling

In this module, we will examine the methods and best practices for scaling cloud servers. You will learn when to use vertical scaling for capacity increases and how to implement horizontal scaling with auto load balancers for optimal performance under growing workloads.
