Designing a scalable, secure, and cost-efficient solution on AWS requires structuring your architecture around modular cloud building blocks, automation, and well-established best practices. Here is the CloudPi.ai recommended approach:
Every AWS solution should be evaluated against the six pillars:
Operational Excellence
Security
Reliability
Performance Efficiency
Cost Optimization
Sustainability
This ensures your architecture stays stable, efficient, and future-proof.
Separate workloads by purpose:
Production
Staging / QA
Dev/Test
Shared Services (Networking, IAM, Logging)
This improves security isolation, simplifies access control, and reduces blast radius.
Use:
VPC per environment
Public/Private subnets split across AZs
VPC Endpoints for secure private traffic
Transit Gateway if connecting multiple VPCs
WAF + CloudFront for global security and caching
CloudPi.ai recommends selecting based on workload type:
Use CaseBest AWS OptionEvent-drivenLambda + EventBridgeWeb appsFargate / ECS or EKSHigh-speed processingEC2 Auto ScalingEdge workloadsLambda@Edge / CloudFront Functions
Reduce operational burden with:
RDS / Aurora → relational DB
DynamoDB → serverless NoSQL
S3 → static assets, backups, logs
API Gateway → managed API layer
SNS/SQS → messaging decoupling
Managed services improve uptime, scalability, and security.
A CloudPi.ai architecture always includes full monitoring:
CloudWatch metrics + alarms
CloudTrail auditing
AWS Config compliance
OpenSearch / Grafana for analytics
Use Infrastructure as Code from day one:
Terraform (CloudPi.ai primary recommendation)
AWS CloudFormation / CDK
Automated CI/CD pipelines using GitHub Actions, GitLab CI, or AWS CodePipeline
CloudPi.ai’s AWS security baseline includes:
IAM least-privilege roles
MFA for all human access
Secrets Manager / Parameter Store
KMS encryption everywhere
GuardDuty + Security Hub
S3 default block-public-access
Use:
Auto Scaling
Spot Instances for batch workloads
S3 lifecycle policies
Compute Optimizer recommendations
A well-architected AWS solution should be:
✔ Modular
✔ Secure
✔ Automated
✔ Observed
✔ Cost-optimized
✔ Built on managed services
