1. Introduction to Azure Cloud 2026

1.1 What is Azure?

The short answer: Azure can be everything. It encompasses virtually every cloud service available on the market today. You can move virtual machines to the Azure cloud, offload file storage, file servers, websites, and your network infrastructure whenever you need them—as long as you’re willing to pay for it.

Microsoft Azure is a powerful cloud computing platform that gives you a broad range of services to develop, deploy, and manage your applications. From Azure Virtual Machines and Azure SQL Database to Azure Kubernetes Service (AKS), Azure has what you need.

1.4 Azure Accounts and Subscriptions

• Overview of subscription types and models

Azure Accounts

To get started with Microsoft Azure, you need an Azure account. Your account serves as your entry point to access Azure’s cloud services and resources. You can sign in with an existing Microsoft ID or create a new one.

Azure Subscriptions

An Azure subscription is a container for a group of Azure resources. It helps you organize and monitor billing, management, and service usage. You can have multiple subscriptions under a single Azure account, which is particularly useful for separating different projects, environments (such as development, testing, and production), or billing purposes.

Subscription Types

• Free Account Azure offers a free account that gives you access to various services for 12 months plus a credit for your first 30 days. Perfect for exploring and learning Azure.

• Pay-As-You-Go This model lets you pay only for the resources you actually use. There are no upfront costs or long-term commitments.

• Enterprise Agreement (EA) A customized solution for large enterprises with high usage needs, offering negotiated pricing and contract terms.

• Microsoft Partner Network (MPN) For Microsoft Partners wanting to use Azure services at reduced rates.

Pricing Models

Usage-based billing Azure uses a consumption-based billing model where you pay only for the resources and services you actually use. This provides flexibility and helps optimize costs.

Per-service pricing

Each Azure service has its own pricing model based on usage, storage, data transfer, and other factors. For example:

Azure Virtual Machines Billed by compute power (vCPUs), storage type, and runtime.

Azure Storage Costs based on storage space used and data transfers.

Azure SQL Database Billed by performance tier, database size, and transaction volume.

Cost management tools Azure provides several tools to monitor and manage your spending:

Azure Cost Management + Billing A central dashboard for tracking expenses, planning budgets, and optimizing costs.

Pricing calculator An online tool to estimate costs for your planned Azure resources.

Reports and alerts Automated reports and notifications help you stay within budget and avoid unexpected charges.

Discounts and savings plans

Reserved Instances Get significant discounts by committing to compute capacity for one or three years upfront.

Spot Instances Use unused capacity at heavily reduced rates for non-critical workloads.
