Question 1

Should I use AWS Lambda (serverless) or containers (ECS/EKS)?

Accepted Answer

Choose Lambda when your workload is event-driven, has variable traffic with idle periods, consists of short-lived operations (under 15 minutes), and you want zero server management. Choose ECS Fargate or EKS when you need long-running processes, consistent high throughput, more control over networking and compute resources, or are running applications that do not fit the serverless model (WebSocket servers, background workers). Many of our architectures use both — Lambda for API endpoints and event processing, containers for background workers and stateful services.

Question 2

How much does AWS infrastructure cost for a typical application?

Accepted Answer

A startup application serving 1,000-10,000 monthly active users typically costs $100-$500/month on a serverless architecture. A growth-stage SaaS serving 10,000-100,000 users runs $500-$3,000/month. Enterprise applications with high availability, multi-region deployment, and large databases range from $5,000-$50,000/month. We help you project costs accurately during the architecture phase and implement tagging, budgets, and alerts to prevent bill surprises. Our cost optimization audits typically save clients 25-40% on existing AWS spend.

Question 3

Do you use Terraform or AWS CDK for Infrastructure as Code?

Accepted Answer

We default to Terraform for most projects because it is cloud-agnostic (useful if you ever need multi-cloud), has the largest community and module ecosystem, and provides a clear, declarative syntax that is easy for teams to review and understand. We use AWS CDK when a project is exclusively on AWS and the team prefers writing infrastructure in TypeScript alongside their application code. Both tools achieve the same goal — version-controlled, reproducible infrastructure — and we are deeply experienced with both. The choice usually comes down to team preference and existing tooling.

Question 4

How do you handle security on AWS?

Accepted Answer

Security is built into every layer of our AWS architectures. We implement least-privilege IAM policies, VPC isolation with private subnets for databases and internal services, encryption at rest (KMS) and in transit (TLS 1.3), WAF rules for web application protection, and GuardDuty for threat detection. We use AWS Secrets Manager for credential management and enforce multi-factor authentication on all accounts. For compliance-sensitive workloads (healthcare, fintech), we implement additional controls aligned with HIPAA, PCI DSS, or SOC 2 requirements and can support your audit process with architecture documentation.

Question 5

Can you optimize our existing AWS infrastructure to reduce costs?

Accepted Answer

Absolutely, and we do this regularly. Our AWS cost optimization engagements typically reduce monthly spend by 25-40%. Common savings come from right-sizing over-provisioned EC2 instances, purchasing Reserved Instances or Savings Plans for predictable workloads, migrating to Graviton ARM processors (20% cheaper, 20% faster), eliminating unused resources (idle load balancers, unattached EBS volumes), optimizing S3 storage classes, and implementing auto-scaling policies. We provide a detailed report with projected savings for each recommendation so you can prioritize changes.
