All Patterns & Migration Flashcards
Q: What are the 5 Rs of cloud migration?
A: Rehost (lift-and-shift), Refactor (minor changes), Rearchitect (significant redesign), Rebuild (rewrite), Replace (SaaS adoption).
Q: When should you use the CQRS pattern?
A: When read and write workloads have different performance requirements. Separate read models (optimized queries) from write models (optimized transactions).
Q: What is the circuit breaker pattern?
A: Prevents cascading failures by detecting failures in a downstream service and failing fast without attempting the call. States: closed, open, half-open.
Q: When to use Event Grid vs Service Bus vs Event Hubs?
A: Event Grid: reactive event routing (pub/sub). Service Bus: reliable enterprise messaging (queues/topics). Event Hubs: high-throughput streaming ingestion (millions/sec).
Q: What is Azure Migrate used for?
A: Discovery, assessment, and migration of on-premises servers, databases, and applications to Azure. Provides sizing recommendations and cost estimates.
Effective Azure Flashcard Study Method
For Azure certifications, we recommend the spaced repetition approach: review these flashcards daily for the first week, then every other day for two weeks, then weekly until your exam date. Focus extra time on cards related to Azure service comparisons — understanding when to choose between similar services (e.g., App Service vs. AKS vs. Container Instances) is a common exam pattern.
