3. Master design strategies to overcome limits, including using event-driven architectures, splitting workloads, and integrating services like Step Functions and SQS for scalability.

1. When AWS Lambda runs inside a Amazon VPC, it attaches to your private subnets using ENIs (Elastic Network Interfaces)—giving your function private IP access to internal resources like databases.

2. This setup lets Lambda securely talk to services such as Amazon RDS or internal APIs, but removes default internet access unless you configure a NAT Gateway or VPC endpoints.

3. The trade-off: stronger security and control, but slightly higher latency during cold starts due to ENI provisioning—an important consideration for performance-sensitive workloads and exams.

1. Cold starts impact latency — When AWS Lambda spins up a new execution environment, initialization delay can slow responses, especially for infrequent or unpredictable workloads.

2. Service limits shape architecture — Concurrency limits, payload size, timeout, and memory constraints directly influence how you design scalable and reliable serverless applications.

3. Exam questions test trade-offs — Expect scenarios where you must reduce cold starts (Provisioned Concurrency) or design around limits using services like SQS, Step Functions, or API Gateway.

1. Event-Driven Architecture lets your systems respond automatically to real-time events—no constant checking or manual triggers needed.
