Phase 5: Designing Compute, Network, and Application Infrastructure

Welcome to Phase 5, where we delve into the core of Azure infrastructure design: compute, network, and application architecture. Building upon your understanding of Azure's foundational concepts, governance, identity, data storage, and business continuity, this section focuses on the practical application of designing and optimizing your cloud infrastructure for performance, scalability, and efficiency.

This phase is crucial for the AZ-305 exam, which demands not just recall, but the ability to analyze, evaluate, and create architectural designs for infrastructure. We'll explore architectural patterns and best practices that ensure your applications are deployed on the most suitable compute resources, communicate securely and efficiently over a robust network, and can be migrated from on-premises environments effectively. The focus here is on comprehension and practical application, enabling you to design high-performing and scalable infrastructure solutions.

Scenario: You're tasked with designing the entire infrastructure for a new enterprise application. This involves selecting compute resources (VMs, PaaS, containers, serverless), designing a secure and performant network topology, and planning the migration of existing workloads from on-premises.

Reflection Question: How do the choices for compute, network, and migration strategies collectively influence the overall performance, scalability, security, and cost-effectiveness of your Azure infrastructure design?
