Introduction

Welcome to the first module of our guide on foundational cloud computing concepts. In this module, we explore the key building blocks of cloud computing, including its transformative impact on the modern business landscape.

We will cover several essential topics:

• An overview of cloud computing and its core principles.
• A discussion of different cloud deployment models.
• A comparison between capital expenditure (CapEx) and operational expenditure (OpEx) in cloud environments.
• The numerous benefits of cloud services, such as scalability, flexibility, and cost efficiency.
• A detailed breakdown of cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
• An explanation of the Shared Responsibility Model, emphasizing its significance for security and compliance in the cloud.

Throughout this module, we will use real-world examples from a fictional company, Vela Innovations, to illustrate how cloud computing can address diverse business challenges.
