☁️ Exam Guide: Cloud Practitioner
Domain 1: Cloud Concepts
📘 Task Statement 1.3
🎯 What Is This Task Testing?
This objective focuses on whether you understand:
- Cloud adoption strategies (how organizations plan and execute migration)
- Resources that support migration
- The benefits of the AWS Cloud Adoption Framework (AWS CAF)
- How to choose appropriate migration strategies/tools for a scenario (e.g., database replication, AWS Snowball)
1) 🧭 Cloud Adoption Strategies
Cloud adoption is more than “moving servers.” It typically includes:
- Aligning cloud goals to business outcomes: cost, speed, resilience, innovation
- Planning for people/process changes: skills, operations, governance
- Selecting migration approaches per workload: not every app moves the same way
- Executing in phases: (pilot → migrate → optimize)
2) 🧩 AWS Cloud Adoption Framework (AWS CAF)
AWS CAF is guidance that helps organizations plan and manage a cloud adoption journey by addressing business and technical considerations. The goal is to reduce uncertainty and increase the likelihood of successful migration and modernization.
Benefits of AWS CAF
- Reduced business risk: clearer planning, governance, security approach, and migration sequencing
- Improved ESG performance: more efficient infrastructure use, less wasted capacity, potential reduction in environmental impact
- Increased revenue: faster delivery of new features/products, global expansion, improved customer experience
- Increased operational efficiency: automation, standardized processes, improved monitoring, and better resource utilization
3)🧰 Resources That Support the Migration Journey
AWS provides multiple programs and services to help customers assess, mobilize, and migrate.
Common resource types: (what they’re for)
- Assessment & planning: evaluate readiness, build a business case, identify dependencies
- Migration & transfer services: move servers, databases, and large datasets
- Partner support: system integrators and AWS Partners can help execute migrations
- Ongoing guidance: best practices for operations, security, and architecture after migration
4) 🗺️ Identifying Appropriate Migration Strategies
Different workloads require different strategies.
A. Database replication 🔁
When it’s appropriate:
- you want minimal downtime (or near-zero downtime)
- you need to keep source and target databases in sync during migration
- you want a gradual cutover rather than a hard stop
B. AWS Snowball 📦
What it is: a physical device used to transfer large amounts of data into AWS.
When it’s appropriate:
- very large datasets (terabytes/petabytes)
- limited bandwidth or slow/expensive internet connectivity
- need for secure offline transfer with chain-of-custody style handling
Exam scenario signals:
- “network link is too slow”
- “moving petabytes of data”
- “upload would take weeks/months”
- “remote location with poor connectivity”
✅ Quick Exam-Style Summary
- AWS CAF helps plan adoption and improves outcomes (risk reduction, ESG, revenue, operational efficiency).
- Choose migration strategies based on constraints:
- Database replication → minimize downtime and support gradual cutover.
- AWS Snowball → move massive datasets when bandwidth is limited.
