AWS identifies six main migration strategies, commonly known as the 6 Rs, that help businesses transition to the cloud effectively.
1. **Rehosting (Lift and Shift)**: This involves moving applications to the cloud with minimal modifications. It's the fastest approach, ideal for organizations seeking quick migration while maintaining existing architecture.
2. **Replatforming (Lift, Tinker, and Shift)**: Applications are moved with some optimizations to leverage cloud capabilities, such as migrating databases to managed services like Amazon RDS, while keeping the core architecture intact.
3. **Repurchasing (Drop and Shop)**: Organizations switch to different products, typically moving from traditional licenses to Software-as-a-Service (SaaS) solutions. For example, moving from an on-premises CRM to Salesforce.
4. **Refactoring (Re-architecting)**: This involves redesigning applications using cloud-native features to improve scalability, performance, and agility. It requires significant effort but maximizes cloud benefits.
5. **Retire**: Organizations identify IT assets that are no longer useful and can be turned off, reducing costs and complexity during migration.
6. **Retain**: Some applications may remain on-premises due to compliance requirements, recent upgrades, or complexity, with plans for future cloud migration.
Successful cloud adoption requires careful planning, including assessing current infrastructure, defining business objectives, evaluating security requirements, and training staff. Organizations should consider factors like total cost of ownership, operational efficiency, and business continuity when selecting their strategy.
AWS provides tools like AWS Migration Hub, AWS Application Discovery Service, and AWS Database Migration Service to facilitate these transitions. The Cloud Adoption Framework (CAF) offers guidance across six perspectives: Business, People, Governance, Platform, Security, and Operations, ensuring comprehensive transformation success.
Cloud Adoption Strategies
Why Cloud Adoption Strategies are Important
Cloud adoption strategies are fundamental to understanding how organizations transition from traditional on-premises infrastructure to cloud-based solutions. For the AWS Cloud Practitioner exam, this topic is essential because it demonstrates your understanding of how businesses approach cloud migration and transformation, which is a core concept AWS expects practitioners to grasp.
What are Cloud Adoption Strategies?
Cloud adoption strategies refer to the methodical approaches organizations use to migrate their workloads, applications, and data to the cloud. AWS recognizes several key frameworks and strategies:
The 6 R's of Migration:
1. Rehost (Lift and Shift) - Moving applications to the cloud with minimal changes. This is the fastest approach and is often used for quick migrations.
2. Replatform (Lift, Tinker, and Shift) - Making a few cloud optimizations to achieve tangible benefits while not changing the core architecture.
3. Repurchase (Drop and Shop) - Moving to a different product, typically a SaaS platform like moving from an on-premises CRM to Salesforce.
4. Refactor/Re-architect - Reimagining how the application is architected using cloud-native features. This approach offers the most benefits but requires the most effort.
5. Retire - Identifying IT assets that are no longer useful and can be turned off.
6. Retain - Keeping certain applications on-premises, usually due to compliance requirements or recent upgrades.
AWS Cloud Adoption Framework (AWS CAF)
AWS provides a structured approach through six perspectives:
- Business Perspective: Ensures IT aligns with business needs - People Perspective: Supports change management and organizational readiness - Governance Perspective: Focuses on skills and processes for IT governance - Platform Perspective: Helps design and implement cloud solutions - Security Perspective: Ensures security objectives are met - Operations Perspective: Defines day-to-day operations in the cloud
How Cloud Adoption Strategies Work
Organizations typically follow these phases:
1. Assessment Phase: Evaluate current infrastructure, applications, and dependencies 2. Planning Phase: Develop a migration strategy and timeline 3. Migration Phase: Execute the chosen strategy for each workload 4. Optimization Phase: Fine-tune resources and costs post-migration
Exam Tips: Answering Questions on Cloud Adoption Strategies
Key Points to Remember:
- Rehost is the quickest migration path but offers fewer cloud-native benefits - Refactor provides the most long-term benefits but requires more time and resources - Repurchase involves moving to SaaS solutions - Retire means decommissioning applications you no longer need - Retain is appropriate when migration is not suitable for certain workloads
Common Question Patterns:
- When a question mentions minimal changes or fastest migration, think Rehost - When a question mentions cloud-native features or maximum optimization, think Refactor - When a question mentions moving to a commercial product, think Repurchase - When a question asks about applications that should stay on-premises, think Retain
