Application Integration
Q In AWS Step Functions, what handles retries and error catching?
A Declarative configuration in the state machine definition — no retry logic to code.
new ⧉ same passage aws step-functions workflow-orchestration error-handling
Q What are AWS Step Functions?
A A managed workflow orchestration service that executes state machines, tracks state, and handles retries declaratively.
new ⧉ same passage aws step-functions application-integration orchestration
Q What is the maximum execution duration for a Step Functions Standard workflow?
A One year
new aws step-functions serverless workflow-orchestration
Q What delivery guarantee do Step Functions Express workflows provide?
A At-least-once (not exactly-once)
new aws step-functions workflow-types
Q What is the payload size limit between states for Amazon Step Functions?
A 256 KB. Large documents and long model outputs must be passed by S3 reference rather than inline
new step-functions aws limits application-integration
Q What is the main cost argument for using Step Functions Express workflows over Standard workflows?
A Standard workflows charge per state transition, making high-volume or chatty workflows expensive.
new aws step-functions cost-optimization serverless
Q When should you use EventBridge instead of Step Functions for a multi-system reaction?
A When multiple unrelated things must react to one event — fan-out, not a sequence.
new aws eventbridge step-functions application-integration
Q When is a state machine (Step Functions) overkill for a queued workload?
A When there's only one processing step — use SQS + Lambda instead.
new aws step-functions sqs application-integration
Q When should you choose an agent over Step Functions for a generative pipeline?
A When the sequence of steps cannot be known in advance and must be decided by the model at runtime.
new aws step-functions bedrock-agents orchestration generative-ai
Q Which AWS tool is designed for short, simple, visual generative chains built by non-engineers?
A Amazon Bedrock Prompt Flows
new aws generative-ai prompt-flows orchestration
Q What property of EventBridge means producers don't need to be updated when new consumers are added?
A Producers publish events without knowing who the consumers are (decoupling).
new ⧉ same passage aws eventbridge event-driven decoupling
Q What is Amazon EventBridge?
A A serverless event bus that routes events by content rules to multiple targets, with producers decoupled from consumers.
new ⧉ same passage aws eventbridge application-integration event-driven
Q What architectural property does EventBridge provide when routing S3 events to a Step Functions workflow?
A The producer (S3) has no knowledge of its consumers — full decoupling.
new aws eventbridge event-driven-architecture decoupling
Q In event-driven document processing, what triggers a Step Functions workflow when a document arrives in S3?
A EventBridge routes the S3 event to the Step Functions workflow.
new aws eventbridge step-functions event-driven-architecture
Q What is EventBridge Archive and Replay used for in operational resilience?
A Reprocessing past events after fixing a bug, or rebuilding a downstream store.
new aws eventbridge event-driven operational-resilience
Q Which AWS service is the modern replacement for CloudWatch Events rules when scheduling recurring jobs at scale?
A EventBridge Scheduler
new aws eventbridge scheduling cloud-architecture
Q In SQS, what three actions does a consumer perform on each message?
A Poll, process, then delete it.
new aws sqs messaging
Q What is the primary purpose of Amazon SQS?
A A managed message queue: producers send messages, consumers poll, process, and delete them.
new aws sqs messaging integration
Q What is the preferred architectural solution when a generative pipeline experiences throttling under burst load, as a cheaper alternative to Provisioned Throughput?
A Buffering requests with SQS, often combined with exponential backoff
new aws sqs bedrock application-integration throttling
Q What delivery channels can SNS reach that SQS and EventBridge cannot?
A Email, SMS, and mobile push
new aws sns application-integration messaging
Q What is the primary purpose of Amazon AppFlow?
A Managed data transfer between SaaS applications and AWS without writing integration code.
new aws appflow application-integration saas
Q When should you choose AppFlow over native Q Business/Knowledge Base connectors to ingest SaaS data?
A When the destination is S3 for multiple consumers (analytics, ML, etc.), not just a search index.
new aws appflow application-integration generative-ai
Q How does AWS AppConfig prevent bad configuration from reaching production?
A Validators (JSON Schema or Lambda) reject invalid config before deployment.
new aws appconfig configuration-management feature-flags
Q What AWS service manages application configuration and feature flags separately from application code?
A AWS AppConfig (a capability of Systems Manager)
new aws appconfig systems-manager feature-flags
