  8. 8. Azure and Google Growing Faster than AWS 7
  9. 9. ● Cost considerations ● Vendor leverage ● Vendor diversity ● Desire to use unique services ● Need for particular regions ● Strategic reasons 6 Reasons Companies Move Public Clouds 8
  10. 10. • Migration (one-time) • Onboard – migrate to cloud for first time • Cloud to Cloud – move from cloud A to cloud B • Portability (ongoing) • Semi-portable – architected to move later with some effort • Fully-portable – can deploy seamlessly on multiple supported clouds Migration vs Portability 9
  11. 11. Use Cases for Portability • Most Common • Avoid lock-in • Ability to move at some point • Best venue approach (typically for batch/dev/qa) • Geography, Cost, Features • Lifecycle approach • Dev/Test vs. Staging/Production on different resource pools • Disaster Recovery • Less Common • Split-tier architectures • Cloud-bursting
  12. 12. 1. What are your motivations/goals? 2. Map services you use across clouds • Plan for how to deal with services that are missing or significantly different 3. Map regions you use across clouds 4. Map detailed billing items • Instances, Storage, Network, Other Services 5. Model discounts for each cloud 6. Review technical considerations 7. Make a decision based on services, regions, costs and your goals Steps to Take Before You Make the Move 11
  13. 13. COMPARING CLOUD SERVICES
  14. 14. Similar VM Sizes for AWS, Azure, and Google 13 Google offers higher CPUs (currently in Beta)
  15. 15. Compliance Certifications are Equivalent 14
  16. 16. Available Regions by Cloud Provider 15
  17. 17. • Same country, closest region • Same country, lowest price nearby region • Example: Currently in AWS US-East (N. Virginia) • Consider Google South Carolina instead of Northern Virginia • Consider nearby countries in some cases • Example: Currently in Google London • Consider Azure North Europe (Ireland) or West Europe (Netherlands) Region Approaches When Moving 16
  18. 18. Database Options by Cloud Provider 17
  19. 19. Application Services by Cloud Provider 18
  20. 20. • Example one: On AWS, considering move to Google • Using NFS from AWS Marketplace • No equivalent on Google at the time (now Google Cloud Filestore is in Beta) • Decision to stay on AWS and switch to AWS EFS • Example 2: On AWS, considering move to Google • Google ILB (Internal Load Balancer) was missing a feature the customer needed • Decision to move anyways • Customer “rolled their own” with Nginx What If It’s a Mismatch? 19
