Deployment, Migration, Serverless and Containers
This topic covers migration services, container services, serverless architecture, deployment options, application hosting, and modernization paths.
How to study for AWS Cloud Practitioner
Treat each question as a service-selection or responsibility decision: identify the business need, AWS responsibility, customer configuration, and best-fit service.
Core concepts
Concept 1
Migration services help discover, move, sync, or transfer applications, servers, databases, and data to AWS.
Exam cue: Use DMS for database migration.
Concept 2
Serverless and container services reduce infrastructure management while supporting different packaging and scaling models.
Exam cue: Use ECS or EKS for container orchestration choices.
Concept 3
Deployment decisions depend on operational control, portability, scaling, event patterns, and application architecture.
Exam cue: Use Lambda for event-driven serverless code.
Risk pitfalls and guardrails
Using a database migration tool for general file transfer.
Guardrail: Avoid answers that ignore customer configuration, choose unmanaged services when managed services fit, or use billing reports when proactive alerts are required.
Choosing Kubernetes-specific services when the scenario only needs a managed container runtime.
Guardrail: Avoid answers that ignore customer configuration, choose unmanaged services when managed services fit, or use billing reports when proactive alerts are required.
Assuming serverless means there is no customer code or configuration responsibility.
Guardrail: Avoid answers that ignore customer configuration, choose unmanaged services when managed services fit, or use billing reports when proactive alerts are required.
Memory anchors
DMS
AWS Database Migration Service migrates databases to AWS with minimal downtime for supported sources.
Migration Hub

App Runner
AWS App Runner builds and runs web applications and APIs from source or container images.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
