Description
Do you want a solid understanding of cloud fundamentals to ace technical interviews and confidently apply cloud skills in real-world projects? This beginner-friendly course offers a comprehensive look at cloud computing principles, from how traditional on-premises data centers have evolved into today’s scalable and cost-efficient cloud platforms, to the critical differences between monolithic on-prem setups and modern distributed architectures.By tracing cloud computing back to mainframes and time-sharing, you’ll see how on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service emerged as the five core features of a robust cloud environment. We’ll dissect the essence of cloud models—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—to help you choose the right solution for your projects. You’ll learn the importance of deployment models (public, private, and hybrid) and how each fits different organizational needs, compliance requirements, and cost structures.Hands-on sections will walk you through the fundamentals of spinning up virtual machines, planning resource capacity, and ensuring high availability through multi-region and multi-availability zone strategies. We’ll also cover game-changing concepts like elasticity, fault tolerance, the shared responsibility model, and best practices to prepare you for cloud-centric job interviews.Whether you’re a developer, aspiring architect, or IT enthusiast, this course is crafted to give you the core knowledge you need to discuss and implement cloud computing with confidence. You’ll leave equipped to tackle interview questions on scalability, cost management (CapEx vs. OpEx), and the critical trade-offs between on-prem infrastructure and public cloud services. Enroll now to jump-start your cloud computing journey and stand out in your next interview or team project.
