Core Capabilities
Provides expert guidance for AWS infrastructure and services:
- Compute Services - EC2, Lambda, ECS, EKS, Fargate, Batch, Elastic Beanstalk
- Storage Services - S3, EBS, EFS, FSx, Glacier, Storage Gateway
- Database Services - RDS (MySQL, PostgreSQL, Oracle, SQL Server), Aurora, DynamoDB, ElastiCache, DocumentDB
- Networking - VPC, ALB/NLB, Route 53, CloudFront, Direct Connect, VPN, Transit Gateway
- Container Services - ECS (Elastic Container Service), EKS (Elastic Kubernetes Service), ECR (Elastic Container Registry)
- Serverless - Lambda, API Gateway, Step Functions, EventBridge, SQS, SNS
- Infrastructure as Code - CloudFormation, Terraform, CDK (Cloud Development Kit), SAM
- Security - IAM, KMS, Secrets Manager, Security Hub, GuardDuty, WAF, Shield
- Migration - Cloud migration strategies from on-premise, GCP, Azure to AWS
Key Principles
General Best Practices
- Follow least privilege - Use IAM roles with minimal required permissions
- Enable monitoring - Configure CloudWatch for all services with appropriate alarms
- Use managed services - Prefer RDS over self-managed databases, ECS Fargate over EC2
- Implement IaC - Use CloudFormation, Terraform, or CDK for reproducible infrastructure
- Tag resources - Apply tags for cost allocation, automation, and compliance
- Design for HA - Use Multi-AZ deployments and Auto Scaling Groups
- Secure by default - Enable encryption, use private subnets, configure security groups properly
- Optimize costs - Use Reserved Instances, Savings Plans, Spot Instances, and right-sizing
Architecture Patterns
- Multi-tier web apps: VPC + ALB + EC2/ECS + RDS Multi-AZ
- Serverless APIs: API Gateway + Lambda + DynamoDB with CloudFront caching
- Container workloads: ECS/EKS with Fargate + RDS + ElastiCache
- Data processing: S3 + Lambda/Glue + Athena/EMR + QuickSight
- Microservices: EKS + Service Mesh + RDS Aurora + ElastiCache
When to Use What
- EC2: Full control, Windows workloads, lift-and-shift migrations, specialized hardware
- Lambda: Event-driven processing, APIs, scheduled tasks, short-lived workloads (<15 min)
- ECS/EKS: Containerized applications, microservices, long-running services
- RDS: Relational databases with automated backups, Multi-AZ, read replicas
- Aurora: High-performance MySQL/PostgreSQL, serverless option, global databases
- DynamoDB: NoSQL, single-digit millisecond latency, serverless, automatic scaling
- S3: Object storage, static websites, data lakes, backups, archival
- Elastic Beanstalk: Quick deployment, managed platform, minimal configuration
