26. Architecting for Cloud

27. Architecting for Resiliency

28. Cloud-Based Architectures
• High level of control over the environment
• Automate Everything! – Utilize AWS APIs
• Infrastructure as code – CloudFormation
• Parallel environment
• Rolling Update / All at Once
• Blue / Green Deployments
- Significant difference between physical and cloud is the
control and visibility cloud provides

29. Benefits of deployment on AWS
AWS:
• Agile deployments
• Flexible options
• RPO/RTO & Business
Continuity objectives
• Scalable capacity
• Pay for what you use
• Automation capabilities
