Microsoft Azure is a comprehensive cloud platform that offers a broad set of services designed to help organizations build, deploy, and manage applications. Among the most critical categories of services are Compute, Storage, and Networking. These form the foundation of any cloud architecture. In this post, we’ll explore the core Azure services in each of these domains and how they support modern cloud workloads.
1. Azure Compute Services
Azure’s compute services allow you to run applications and workloads on-demand in the cloud. Key offerings include:
Azure Virtual Machines (VMs)
Azure VMs offer IaaS-based compute power, allowing users to deploy virtualized Windows or Linux environments quickly and cost-effectively.
- Use case: Hosting web servers, legacy apps, or custom environments.
- Scalable with VM scale sets.
Azure App Services
A PaaS offering for hosting web applications, REST APIs, and mobile backends. You don’t need to manage infrastructure—just focus on your code.
- Built-in CI/CD, autoscaling, and authentication.
Azure Functions
A serverless compute service for running event-driven code without managing servers.
- Ideal for automation, background jobs, and microservices.
2. Azure Storage Services
Azure provides multiple storage options for a variety of needs, from unstructured data to backups and big data.
Azure Blob Storage
Object storage optimized for massive amounts of unstructured data like images, videos, and logs.
- Tiers: Hot, Cool, Archive for cost optimization.
Azure Disk Storage
Persistent block storage used with Azure VMs.
- Supports premium SSD, standard SSD, and HDD.
Azure File Storage
Fully managed file shares accessible via the SMB protocol.
- Great for lift-and-shift applications requiring file shares.
Azure Data Lake Storage
Optimized for big data analytics workloads with high throughput and scalability.
3. Azure Networking Services
Azure’s networking services connect and secure your cloud resources and users around the world.
Azure Virtual Network (VNet)
The backbone of Azure networking, allowing private IP communications between Azure resources.
- Supports subnets, routing, and peering.
Azure Load Balancer
Distributes incoming network traffic across multiple resources to ensure high availability and reliability.
- Layer 4 load balancing for TCP and UDP.
Azure Application Gateway
A Layer 7 load balancer with web application firewall (WAF) capabilities.
- Ideal for HTTP/S traffic, SSL termination, and session affinity.
Azure VPN Gateway
Connects on-premises networks to Azure via secure VPN tunnels.
Benefits of Azure Core Services
- Scalability: Instantly adjust compute and storage as demand changes.
- Security: Built-in encryption, access controls, and compliance.
- Reliability: Globally distributed data centers with SLAs up to 99.99%.
- Flexibility: Choose from multiple services to match your workload needs.
FAQs: Core Azure Services
Q1: What is the difference between Azure Virtual Machines and Azure App Services?
Azure VMs provide full control over the OS and infrastructure, suitable for legacy apps. App Services offer a managed environment focused on rapid development and deployment.
Q2: Which Azure storage service is best for large unstructured data?
Azure Blob Storage is ideal for storing massive amounts of unstructured data such as images, videos, and logs.
Q3: How does Azure Virtual Network (VNet) work?
A VNet allows you to securely connect Azure resources in a logically isolated network. It supports routing, subnetting, and integration with on-premises networks via VPN.
Q4: What is the use of Azure Load Balancer vs Application Gateway?
- Load Balancer: Works at Layer 4 (TCP/UDP).
- Application Gateway: Works at Layer 7 (HTTP/HTTPS) and offers advanced routing and WAF.
Q5: Is Azure suitable for hybrid cloud scenarios?
Yes, Azure offers services like VPN Gateway, ExpressRoute, and Azure Arc to seamlessly integrate on-premises environments with the cloud.
