4.1. Domain Overview: Deploying & Managing Azure Compute Resources

💡 First Principle: Optimal compute selection requires aligning the architectural patterns, performance characteristics, and operational models of a workload with a purpose-built compute service to ensure a solution that is scalable, efficient, and cost-effective.

Scenario: You're tasked with deploying a new application that requires a mix of Virtual Machines for legacy components, containers for microservices, and serverless functions for event-driven processing. You also need to ensure these compute resources are secure, available, and scalable.

Deploying and managing Azure compute resources begins with a fundamental First Principle: Compute resources must be provisioned and maintained to precisely match workload demands, ensuring optimal performance, scalability, and cost-efficiency. This proactive approach optimizes resource utilization and simplifies operational overhead.

This domain explores how to apply this principle across critical areas, including:

• Virtual Machines (VMs): Deploying and configuring individual VMs.
• VM Deployment Strategies: Utilizing Azure Marketplace, custom images, and ARM templates.
• VM Security: Implementing disk encryption and secure access with Azure Bastion. Load Balancing for VMs: Distributing traffic with Azure Load Balancer and Application Gateway.
• App Service Resources: Managing web apps and APIs with App Service Plans and deployment slots.
• Container Resources: Deploying and managing containers with ACI and AKS.

The focus is on comprehending and applying Azure compute best practices and services to meet specific administrative requirements, ensuring robust and efficient application hosting.

⚠️ Common Pitfall: Defaulting to a familiar compute service (like VMs) without evaluating if a more modern, managed, or serverless option would be a better fit for the workload's characteristics, potentially leading to higher costs and operational burden.

Key Trade-Offs:

• Control vs. Managed Overhead: Services like VMs offer maximum control over the environment, while services like App Service and Containers trade some control for significantly reduced operational management.

Reflection Question: How does choosing the right Azure compute service (VMs, App Service, Containers, Serverless) and configuration, based on application type, scalability, and operational preferences, fundamentally ensure optimal performance, scalability, and cost-efficiency for diverse application workloads?
