What is Microsoft Azure?

Microsoft Azure is Microsoft's cloud computing platform, offering over 200 products and services including compute, storage, networking, AI, databases, and DevOps. Azure is the second-largest cloud provider after AWS and is widely used by enterprises due to its deep integration with Microsoft products like Office 365 and Windows Server.

What does AZ-900 cover?

The AZ-900 Azure Fundamentals exam covers six areas: cloud concepts (IaaS/PaaS/SaaS, shared responsibility), core Azure services (compute, storage, networking), Azure pricing and cost management, core solutions and management tools, general security features, and Azure governance, privacy, and compliance.

What is the difference between IaaS, PaaS, and SaaS?

IaaS (Infrastructure as a Service) gives you virtualised compute, storage, and networking — you manage the OS upward. PaaS (Platform as a Service) provides a platform to build and deploy apps — the provider manages the OS and middleware. SaaS (Software as a Service) delivers complete applications via browser — you only manage your data.

What is the Azure Shared Responsibility Model?

The Shared Responsibility Model defines what the cloud provider (Microsoft) and the customer each manage. Microsoft is always responsible for physical infrastructure. Customer is always responsible for their data and access management. Responsibility for OS, networking, and identity shifts depending on whether you use IaaS, PaaS, or SaaS.

What is high availability in Azure?

High availability means a system continues operating with minimal downtime despite failures. Azure provides high availability through: Availability Zones (physically separate data centres within a region), Availability Sets (spreading VMs across fault domains), and load balancers. Azure's SLA guarantees 99.9% to 99.99% uptime for most services.

What is Azure Resource Manager (ARM)?

Azure Resource Manager is the deployment and management service for Azure. It provides a unified way to create, update, and delete resources in your Azure account. ARM templates let you define infrastructure as code (IaC), enabling repeatable deployments. Resource Groups are logical containers for related resources.

What are the Azure pricing models?

Azure offers: Pay-as-you-go (pay for what you use, no commitment), Reserved Instances (1 or 3 year commitment, up to 72% savings), Spot Pricing (unused capacity at deep discount, can be interrupted), and Azure Hybrid Benefit (use existing Windows Server/SQL Server licences on Azure).

What is the Total Cost of Ownership (TCO) in cloud?

TCO analysis compares the cost of running workloads on-premises versus in the cloud. On-premises TCO includes: hardware, power, cooling, physical space, IT staff, maintenance, and security. Cloud TCO: usage-based costs but no capital expenditure. Azure's TCO Calculator helps organisations estimate cloud savings.
