Azure Services: The Complete Guide

Launched in 2010, Microsoft Azure is one of the leading cloud providers in the market. It is now being used by 85% of Fortune 500 companies. Approximately 56% of global organizations utilize Microsoft Azure as their preferred cloud service provider.

In this article, we’ll explore Azure services, including compute, storage, databases, and networking, and will delve into the benefits Azure services offer.

What are Azure Services?

With nearly 1 billion active users, Azure offers different types of cloud services that are tailored to cater to the diverse needs of numerous industries. Currently, Azure provides more than 200 cloud services, mainly as Platform as a service (PaaS), Software as a service (SaaS), and Infrastructure as a service (IaaS) solutions. In addition to those core services, Azure offers many additional services including: 

Azure service categories based on cloud computing service models

All Azure services can be classified into the following categories based on the cloud computing service model they leverage.

Platform as a Service (PaaS)

PaaS is a cloud-based service model that offers the necessary resources to develop and deploy software applications. It supports the entire software application development lifecycle, eliminating the need to manage infrastructure. PaaS operates on a pay-as-you-go model, enabling users to purchase Azure resources and access them securely over the Internet. 

Following are some of the core Azure PaaS cloud services. 

  • Development - App Configuration, Azure Chaos Studio, DevTest Labs, Load Testing, Microsoft Dev Box
  • Databases - SQL database, Apache Cassandra MI, Database for MariaDB
  • Compute - App service, Azure batch, Azure functions, Cloud services, container apps
  • Integration - API management, Logic apps, service bus.

Software as a Service (SaaS)

Azure SaaS is a service model that allows users to access and utilize cloud-based applications like mail, calendars, and office tools. It allows organizations to deploy applications quickly with minimal costs. Azure manages the hardware and software, such as infrastructure and middleware on your behalf. Therefore, it ensures the high availability and security of those apps.

Following are the SaaS services Azure currently provides: 

  • Analytics - Data Catalog, PowerBI Embedded
  • Development - Azure DevOps, Visual Studio App Center
  • Identity and Security -  Defend for cloud, Information Protection, Microsoft Sentinel
  • IoT - IoT central
  • Management and Governance - Azure Advisor, Azure Arc, Azure Backup
  • Migration - Azure Migrate, DB Migration Service, Site Recovery
  • Networking - Azure Orbital, Internet Analyzer
  • Storage - Data Share

Infrastructure as a Service (IaaS)

IaaS is a cloud service model that provides cloud resources like compute and storage on demand. It also uses a pay-as-you-go model, offering the flexibility to scale resources based on your varying workloads and traffic. It enables organizations to quickly adapt to changing user needs and improve the reliability of their infrastructure.

Following are the IaaS services that Azure currently provides.

  • Compute - Azure VMware Solution, Dedicated Host, Virtual Desktop, Virtual Machines, VM Scale Sets
  • Storage - Azure Storage, HPC Cache, Managed Disks
  • Networking - Azure Firewall, ExpressRoute, Load Balancer, Network Watcher, Private Link, Traffic Manager, Virtual Network, Virtual WAN, VPN Gateway.

Azure foundational, mainstream, and strategic services

Azure services are further categorized as foundational, mainstream, and strategic services. When categorizing these services, their availability in Azure's recommended and alternate regions is taken into consideration.

Foundational services

These are essential or core services provided by the Azure platform. The foundational services are available in all regions recommended for use and in any alternate regions when they become generally available. Additionally, if a new foundational service is introduced, it will be made available in all recommended and alternate regions within 90 days of its general availability.

Some examples of foundational services include: 

  • Azure Application Gateway
  • Azure Backup
  • Azure Cosmos
  • Azure Event Hubs
  • Azure Virtual Machines
  • Azure VPN Gateway

Mainstream services

These services are accessible in all the recommended regions for deployment. They will be made accessible within 90 days from when the recommended region becomes generally available. Additionally, the availability of these services in alternate regions is determined by customer demand within those specific regions. Those services have already been launched and implemented in many alternate regions.

Some examples of mainstream services include: 

  • Azure API Management
  • Azure Container Registry
  • Azure Functions
  • Azure Private Link
  • Azure Virtual WAN

Strategic services

Strategic services were previously known as ‘specialized services.’ They are designed to meet the specific requirements of a particular industry and are developed with a deep understanding of that specific industry. These services leverage customized hardware to enhance performance or enable unique functionality. They are also made available in regions based on customer demand, and many services have already been launched and implemented in many of the recommended regions.

Some examples of strategic services include:

  • Azure API for FHIR
  • Azure Lab Services
  • Azure VMware Solution
  • Azure Applied AI Services
  • Azure Machine Learning
  • Azure Red Hat OpenShift
  • Azure Kubernetes
