Platform¶

The Platform section explains the Azure foundations that shape nearly every workload decision: resource hierarchy, landing zones, identity, networking, compute, data, integration, observability, resilience, and cost.

Why platform decisions come first¶

[Documented] Azure architectures are constrained by management hierarchy, control boundaries, regional placement, and governance mechanisms long before application code matters.

[Inferred] Teams that skip platform fundamentals usually rediscover them later through incidents, policy drift, and expensive redesigns.

Topics covered¶

Topic	Primary question
Azure Architecture on Azure	How Azure organizes global infrastructure and resource control
Resource Organization	How to shape management groups, subscriptions, resource groups, naming, and tags
Landing Zones Basics	What shared platform baselines should exist before workloads scale
Identity and Governance Foundations	How access, policy, and privilege boundaries are enforced
Network Topology Basics	Which connectivity model best fits the estate
Compute Selection Basics	Which compute family matches the workload and team
Data Selection Basics	Which data store family fits consistency, scale, and latency needs
Integration Selection Basics	Which messaging or eventing mechanism fits the interaction pattern
Observability Foundations	How to make workloads measurable and supportable
Resilience and Region Strategy	How region design should align to RTO and RPO targets
Cost Model Basics	How Azure pricing mechanics influence architecture decisions

How to read this section¶

What this section optimizes for¶

[Documented] Microsoft Learn aligned terminology and architecture fundamentals
[Inferred] platform choices that remain stable across many workload types
[Validated] early identification of ownership and guardrail requirements
[Correlated] awareness that cost, security, reliability, and operability interact from the start

What this section avoids¶

This section is intentionally not a deep service tutorial.

It does not try to cover:

portal setup sequences
full deployment examples for each service
runtime tuning detail for specific SKUs
feature matrices better maintained in product documentation

Microsoft Learn anchors¶

Takeaway¶

[Inferred] Strong workload architecture usually starts with boring platform clarity.

Use this section to establish the shared Azure decisions that every later pattern and workload baseline will inherit.
