What is an Azure Subscription?

The right choice of Microsoft Azure subscription is the key to unlocking the benefits of cloud computing. Azure offers flexible subscription options designed to meet the needs of students, startups, and enterprises, ensuring effective resource management, azure subscription cost, and scalability.

Getting an Azure subscription is the first step toward harnessing the potential of Microsoft's highly robust cloud services. This guide will cover Azure's architecture and types of subscriptions and help you determine which one is best for your goals and effective cost management.

What is Subscription in Azure?



It is a joint agreement between Microsoft and an individual or organization wherein access to resources like virtual machines, databases, and storage accounts is given via Azure's services. This associated with an account in Azure with Azure Active Directory (AD), which will serve to authenticate and allow the use of resources.

There are two key usages for subscriptions in Azure:

1. Billing Boundary: Each subscription can support different billing accounts, and the Azure service also offers detailed reports for each.

2. Access Control Boundary: Access control is now role-based through subscriptions, enabling different kinds of access for different teams or projects.

With flexible cloud pricing models and scalability, subscriptions can also be grouped into management groups for centralized administration and governance. In a nutshell, Azure subscription types are the foundation for accessing and managing Azure's powerful cloud services securely and efficiently.

What is Azure Subscription Hierarchy?

The Azure subscription hierarchy is the structured framework to define how to organize, manage, and access Azure resources. It thus ensures efficient management, governance, and scalability throughout an organization's cloud environment. Here is a structured hierarchy of how it will be:

1. Azure Tenant

The Azure tenant represents the highest level and is bound to an organization's Azure AD. It will provide identity and access management to the whole organization, allowing organizations to centrally control users, applications, and permissions.

2. Management Groups

Management groups are containers that help organizations organize subscriptions in a hierarchy of governance and enforcement of policies. They allow organizations to enforce consistent policies like resource compliance or access control across many subscriptions.

3. Azure Subscriptions

An Azure subscription is the core unit for accessing and managing resources. Each subscription has its billing and access control boundaries, which helps organizations separate Azure subscription costs and roles between different departments, projects, or environments.

4. Azure Resource Groups

Resource groups are logical containers that are contained within a subscription to organize resources, such as virtual machines or databases. It makes resource management easier by grouping related assets for an application, project, or workload.

5. Resource

A resource is a single service or item, like a virtual machine, storage account, or database. This is the actual component deployed in Azure and is managed through their separate resource groups.

Types of Azure Services

Azure offers various subscription types, which are specifically tailored to cater to different needs, allowing flexibility in terms of resource access and payment options. Here are the main types:

1. Sponsored or Trial Subscription

This type of account allows users to access a limited set of Azure resources free of charge or for a specific period with pre-defined credits. It is mainly used for testing and learning purposes, and Microsoft might ask for credit card information to verify identity and upgrade free accounts into paid ones. These accounts might have limited features compared to paid subscriptions.

2. Pay-as-You-Go Azure Subscription

The pay-as-you-go model is the most popular and cost-effective option, charging users based on their actual resource consumption. This flexible subscription is ideal for individuals and small businesses, providing enterprise-level access without long-term commitments, and enabling users to control costs by managing resource usage effectively.

3. Enterprise Agreement (EA) Azure Subscriptions

It's designed for larger organizations, as EA subscriptions come with high-volume licenses in return for a commitment to use a fixed amount of resources over a set period. They are less flexible but include some important discounts, promotional benefits, and combining on-premises licenses with Azure resources.

4. Azure Windows Virtual Machines Desktop Reserved Instances

This subscription caters to individuals and small to medium-sized businesses to reserve Azure Virtual Machines for up to three years. The users can pay upfront or every month and enjoy impressive savings, besides priority access to the computing resources of the Azure cloud data centers.

How Can You Use Azure Resources to Scale the Environment?

Organizations can use Azure subscription types to gain an advantage over subscription-level limitations and ensure the scalability of their cloud environment. Scaling your Azure ecosystem effectively involves implementing strategies that maximize resource utilization while meeting organizational objectives. Here's how you can use Azure resources to scale your environment:

1. Assessing subscription-level constraints

Before scaling, evaluate the resource limitations of a single subscription. If one subscription cannot support your needs, consider creating multiple subscriptions to ensure scalability and optimal performance.

2. Plan for Subscription Scaling

When adding new subscriptions, consider factors such as:

• Data transfer costs: Analyze the expenses of data ingress and egress between subscriptions.
• Organizational goals: Align subscriptions with management, innovation, relocation, and security objectives.
• Resource management: Organize and shift resources between subscriptions based on where they fit best.

3. Strategies for Managing Additional Subscriptions

You can organize and scale Azure subscriptions using the following approaches:

• Workload Separation

You can separate subscriptions based on workload types, for example, operational or non-operational workloads. This ensures efficient management and workload division.

• Application Categories

Segment subscriptions based on specific business requirements, access restrictions, compliance, or data protection requirements. Subscriptions can be segmented into mission-critical applications, legal requirements, or cost management.

• Functional Lines

Classify subscriptions under departmental functional lines, including managed IT services, finance, and sales. It ensures better cost allocation and management across teams.

• Business Units

Apply organizational hierarchies to categorize subscriptions by business units or profitability. This helps them align better with business goals and accountability.

For companies that operate in more than one region, classify subscriptions by region to optimize resource utilization and comply with regional regulations.
