This document discusses how to extend an organization's datacenter by migrating workloads and applications to the AWS cloud. It outlines a process for planning, designing, migrating, and reviewing cloud migrations. This includes identifying candidate workloads, networking changes, deploying infrastructure in AWS, configuring monitoring and backups, and testing migrations. The goal is to gradually move applications to AWS while maintaining existing architecture and operational processes.

4. How do we get there?
PlanDesign Migrate Run Review

5. Design
• Do we have a project sponsor?
• What are our timeframes?
• What are the success criteria?
• Are we solving a business issue?
• Do we have the skills in-house? Should we involve a partner?
• Useful AWS resources:
– “Overview of Security Processes” whitepaper
– “Your first hour on AWS” Summit presentation
– “Using AWS in the context of Australian Privacy Considerations” whitepaper
– AWS Operational Checklists
– AWS Architecture Center and reference architectures

6. Plan: candidate use case / workload
• Typical candidates
– Spikey workloads (eg web)
– Test/dev environments
– Backup and archiving
– Hardware replacement
– Disaster recovery

• External dependencies
• Operational processes
– Backup

– Alerting
– Reporting
– Patching
– Upgrades

8. Plan: what needs to change?
• Possible changes:
– Single points of failure
– WAN connectivity
– OS deployment
process
– Backup and recovery
– DR planning
• Unlikely to change:
– Overall architecture
– Application monitoring
– Data structures

20. Migrate: testing
• Functional testing
– Does it work the same as on-prem?
• Stress testing
– Does it handle the load we expect?
– What impact does instance failure have?

21. Review
• What worked? What didn’t?
• What can we re-use?
– VPC: just add more subnets
– Monitoring configuration in place
– CloudFormation to template and repeat
• What are our next candidates?
