Introduction: Understanding Azure Cloud Platform
Microsoft Azure is a comprehensive cloud computing platform offering a vast array of services for building, deploying, and managing applications through Microsoft’s global network of data centers. Azure provides Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) solutions that enable organizations to reduce operational costs, scale efficiently, and innovate faster while maintaining security and compliance.
