📝 Introduction
Cloud computing has revolutionized how we store, access, and manage data. It enables individuals and organizations to operate more efficiently and scale effortlessly. This guide walks you through the essentials of cloud computing.
☁️ What Is Cloud Computing?
Cloud computing refers to the delivery of a wide array of computing services—including servers, storage, databases, networking, software, and analytics—over the internet, commonly known as “the cloud.” In the past, we used to procure all the servers, storage, and other infrastructure ourselves, which involved significant upfront costs and ongoing maintenance. This process required considerable time to procure the necessary hardware and accurately determine server specifications to avoid underutilization or over-specification.
However, with cloud computing, we can access and utilize these resources on-demand from a cloud service provider. This model allows us to purchase everything we need from a single company, which manages and maintains the infrastructure, ensuring scalability, reliability, and cost-efficiency. This approach not only simplifies IT management but also enables businesses to focus on their core operations without worrying about the underlying technical complexities.
