Azure Orientation For PHP Applications

Azure provides virtual machines, App Service, Container Apps, Functions, Kubernetes, managed databases, storage, networking, identity, and monitoring.

Why This Matters

It often fits organizations already using Microsoft identity, governance, and enterprise operations, but PHP workloads should still choose services from runtime needs.

Working Model

Map PHP web applications among App Service, Container Apps, Virtual Machines, AKS, and compatible Functions use cases, with Azure Database services, Cache for Redis alternatives, Blob Storage, networking, Managed Identities, and Azure Monitor.

Practical Rules

  • Use Managed Identity where supported.
  • Choose App Service or Container Apps before AKS unless orchestration needs justify it.
  • Externalize uploads and sessions.
  • Plan deployment slots or revision traffic deliberately.
  • Review quotas and regional availability.

Failure Modes

  • Assuming deployment slots solve incompatible migrations.
  • Embedding storage account keys.
  • Using local application disk for durable files.
  • Choosing a service only because another language team uses it.

Verification

  • Deploy through repeatable automation.
  • Test slot or revision switching.
  • Restore managed data.
  • Trace requests through monitoring.

What You Should Be Able To Do

After this lesson, you should be able to explain Azure compute, identity, data, storage, and operations choices for PHP, choose a suitable approach for a real PHP project, and verify the result instead of relying on assumptions.

Practice

Practice: Choose Azure Compute

Compare App Service, Container Apps, Virtual Machines, Functions, and AKS.

Your answer must:

  • state the intended outcome;
  • show the commands, data flow, or implementation shape;
  • identify at least one unsafe alternative;
  • explain how the result will be verified.
Show solution

Select from runtime packaging, server control, autoscaling, request duration, background processing, networking, and team operational maturity.

The important part is not memorising one command or vendor screen. The solution makes the invariant, failure behavior, and verification evidence explicit.

Practice: Use Managed Identity

A PHP app reads from Blob Storage.

Your answer must:

  • state the intended outcome;
  • show the commands, data flow, or implementation shape;
  • identify at least one unsafe alternative;
  • explain how the result will be verified.
Show solution

Assign a runtime identity, grant the minimum blob role at the narrowest scope, obtain credentials through the platform integration, and avoid static account keys.

The important part is not memorising one command or vendor screen. The solution makes the invariant, failure behavior, and verification evidence explicit.

Practice: Plan Slot Deployment

Use an App Service deployment slot safely.

Your answer must:

  • state the intended outcome;
  • show the commands, data flow, or implementation shape;
  • identify at least one unsafe alternative;
  • explain how the result will be verified.
Show solution

Deploy and warm the slot, apply backward-compatible schema changes first, smoke-test dependencies, switch traffic, monitor, and retain a rollback path that does not depend on reversing destructive migrations.

The important part is not memorising one command or vendor screen. The solution makes the invariant, failure behavior, and verification evidence explicit.
