- Instances for steady workloads, Savings Plans for flexible compute savings, and Spot Instances for fault-tolerant workloads.
- Manage Storage tiering by shifting infrequently accessed data to Amazon S3 Intelligent-Tiering and archiving long-term data to Amazon S3 Glacier. Use serverless architecture, such as AWS Lambda or AWS Fargate, to pay only for usage. For Auto-scaling, use Amazon EC2 Auto Scaling to dynamically match demand.
Q14. Describe the process of aligning cloud architecture with business goals.
Align technical decisions with business outcomes by mapping architecture to business KPIs. Some examples are to reduce infrastructure cost, use serverless architecture, for faster time to market, use CI/CD automation, and for global expansion, use multi-region architecture.
