Study Notes

AWS Cloud Adoption Framework (CAF)

CAF: A collection of best practices, tools, and guidance for businesses migrating to cloud technologies.

Challenges of Cloud Migration

Legacy systems and complex dependencies.
Infrastructure limitations.
Skill and knowledge gaps.

Benefits of CAF

Reduced risk (ensures security, privacy, and business continuity).
Boosted innovation (faster scaling, new product creation).
Enhanced agility (clear strategy for faster adoption and optimization).
Increased revenue (reach more customers and new markets).
Improved efficiency (lower costs, higher productivity).

CAF Use Cases

Resource organization (improved responsiveness and focus).
Technology adoption (simplified infrastructure modernization).
Process improvement (reduced costs and enhanced reliability).
Product development (faster time-to-market and higher deployment frequency).

CAF Key Capabilities

Business: Aligns cloud efforts with business goals (strategy, partnerships, innovation).
People: Supports cultural change and workforce transformation.
Governance: Manages risks and ensures smooth operations.
Platform: Guides scalable cloud system development.
Security: Ensures data protection and threat response.
Operations: Efficient and reliable cloud service delivery.

CAF Steps for Cloud Adoption

Envision: Identify opportunities, set measurable outcomes.
Align: Address gaps, align stakeholders.
Launch: Test migration with pilot projects.
Scale: Expand successful pilots to wider use.

AWS Migration Strategies & Tools

1. Planning the Migration

AWS Application Discovery Service: Gathers detailed info on on-premises IT, creating migration roadmaps.
- Identifies servers, applications, and dependencies.

2. Database Migration

AWS Database Migration Service (DMS): Migrates databases with minimal downtime, keeping the source operational.
- Supports relational (MySQL, PostgreSQL), NoSQL, and data warehouses.
- Offers continuous data replication.
AWS Schema Conversion Tool (SCT): Converts database schemas and code.
- Handles schema changes.
- Supports stored procedures, functions, triggers.
Migration Types:
- Homogeneous: Same database engine (e.g., Oracle to Amazon RDS). Use only DMS.
- Heterogeneous: Different engines (e.g., SQL Server to Amazon Aurora). Use SCT and DMS.

3. Server Migration

AWS Application Migration Service (MGN): Simplifies "lift-and-shift" server migrations.
- Minimal downtime.
- Ideal for rapid transitions.

4. Mainframe Migration

Approaches:
- Rehosting: Move workloads without major changes.
- Refactoring: Redesign apps for cloud-native services.
- Replatforming: Use AWS tools to mimic mainframe functions.
AWS Tools:
- AWS Batch
- Amazon RDS/Aurora
- AWS Glue

5. Data Migration

Online: AWS DataSync, AWS Storage Gateway, S3 Transfer Acceleration for fast, real-time data transfer.
Offline: AWS Snow Family (e.g., Snowcone, Snowball, Snowmobile) for secure, large-scale data transfer between datacenters.

6. Application Modernization

Containerization: Use Amazon ECS, Amazon EKS, or AWS Fargate for containerized app migrations.
Serverless Adoption: Refactor for serverless services like AWS Lambda and API Gateway.
Application Refactoring: Break down monolithic apps into microservices.

7. Data Warehouse Migration

Migrate analytical workloads to Amazon Redshift.
Use AWS Glue for ETL to reduce costs, improve analytics.

8. Hybrid and Multi-Cloud Migration

Hybrid: Use AWS Outposts or AWS Local Zones.
Multi-cloud: Use AWS Migration Hub.

9. Specialized Workloads

Virtual desktops: Amazon WorkSpaces.
Content delivery: Amazon CloudFront.
IoT: AWS IoT Core, AWS IoT Greengrass.

10. Operational Strategies Post-Migration

Tools (e.g., CloudWatch, X-Ray, Trusted Advisor) for monitoring and maintenance.

11. Disaster Recovery and Business Continuity

AWS Elastic Disaster Recovery: Replicates workloads for failover and business continuity.
