About this chapter
What this chapter covers
This is the largest domain of the exam, worth 30 to 35 percent. It covers choosing compute (virtual machines, containers, serverless and batch), designing application architecture (messaging, events, APIs, caching, configuration and deployment automation), planning migrations with the Cloud Adoption Framework, and designing networks (connectivity, performance, security and load balancing).
Questions give a workload and constraints, and you recommend the service that fits with the least operational effort.
How the topics fit together
- Virtual machine and container compute solutions covers VMs, AKS, Container Apps and App Service.
- Serverless and batch compute covers Functions, Logic Apps and Azure Batch.
- Messaging and event driven architecture covers Service Bus, Event Grid and Event Hubs.
- API integration, caching and configuration covers API Management, Redis and App Configuration.
- Automated deployment of applications covers Bicep, pipelines and deployment strategies.
- Migration planning and the Cloud Adoption Framework covers assessment and strategy.
- Migrating workloads, databases and data covers Azure Migrate, DMS and Data Box.
- Connectivity to the internet and on premises covers VPN, ExpressRoute and Virtual WAN.
- Network performance and security covers firewalls, WAF, DDoS and private access.
- Load balancing and routing covers choosing between Front Door, Application Gateway, Traffic Manager and Load Balancer.
Ask three questions in every scenario: how much management does the team want, what are the scale and latency needs, and what is the cost sensitivity.
How to use these pages
Each topic page has the same shape, so you can skim for what you need.
- What it is: the idea in plain words.
- How it works: the mechanism, with examples and tables.
- What to remember for the exam: the facts to memorise and how questions are phrased.
- Common mistakes: the classic traps.
- Check yourself: three questions to test your understanding.
