Module 2: Event Sources and Integration Patterns
- Configure Lambda triggers from S3, DynamoDB Streams, Kinesis, SQS, and EventBridge, evaluating throughput, ordering, and retry behavior.
- Manage SQS-Lambda scaling by tuning batch size, visibility timeout, and error handling to prevent message loss or duplication.
- Design EventBridge event buses for cross-account, cross-service communication while managing event schema evolution and validation.
- Integrate Lambda with API Gateway for REST and HTTP APIs, optimizing for latency, authentication, and payload size limits.
- Implement webhook processing with Lambda, validating payloads, enforcing rate limits, and handling signature verification.
- Orchestrate complex workflows using Step Functions, evaluating trade-offs between standard and express workflows for cost and execution history.
- Handle large payloads exceeding Lambda’s direct integration limits by using S3 references and asynchronous processing.
- Define retry policies and backoff strategies for failed invocations across different event sources and their delivery semantics.
Module 3: Security and Identity Management
- Apply least-privilege IAM roles to Lambda functions, avoiding wildcard permissions and managing role reuse risks.
- Secure environment variables using AWS KMS encryption and control key access through customer-managed CMKs.
- Implement VPC attachment only when necessary, balancing network isolation against cold start penalties and ENI limits.
- Manage cross-account Lambda access using resource-based policies and organizational units in AWS Organizations.
- Enforce function-level authentication using SigV4, JWT validation, or Cognito authorizers in API Gateway.
- Integrate Lambda with Secrets Manager for runtime credential retrieval, managing rotation and caching strategies.
- Audit function execution and configuration changes using CloudTrail, Config rules, and automated compliance checks.
- Isolate sensitive workloads using AWS Lambda SnapStart or container image signing with AWS Signer.
Module 4: Deployment and CI/CD Strategies
- Structure Lambda deployments using AWS SAM or CDK, enabling infrastructure-as-code and environment parity.
- Implement canary, linear, or all-at-once deployment policies using Lambda versions and aliases with CloudFormation or CodeDeploy.
- Automate rollback procedures based on CloudWatch alarms or custom metrics during deployment failures.
- Manage configuration drift by enforcing immutable deployment packages and avoiding runtime configuration overrides.
- Integrate unit, integration, and performance tests into CI pipelines to validate function behavior pre-deployment.
- Optimize deployment package size by removing unused dependencies and leveraging Lambda Layers for shared code.
- Coordinate blue/green deployments across Lambda, API Gateway, and downstream services to minimize risk.
- Enforce deployment gates using policy checks for security, cost, and compliance before promoting to production.
Module 5: Performance Optimization and Cost Management
- Profile function execution duration and memory usage to identify optimal configuration settings for cost-performance balance.
- Minimize execution time through efficient initialization, connection pooling, and external dependency tuning.
- Estimate and forecast Lambda costs using CloudWatch metrics, Cost Explorer, and third-party tools for budgeting.
- Identify and eliminate idle or underutilized functions through usage analysis and automated cleanup policies.
- Compare cost implications of Lambda vs. always-on services for steady-state workloads.
- Optimize invocation patterns to reduce downstream costs (e.g., DynamoDB RCUs/WCUs, S3 requests).
- Use provisioned concurrency judiciously, weighing cost against cold start reduction for critical paths.
- Implement function-level cost attribution using tags and AWS Cost and Usage Reports for chargeback models.
Module 6: Observability and Operational Monitoring
- Configure structured logging with consistent metadata (request ID, function version, trace ID) for correlation across services.
- Instrument functions with AWS X-Ray to trace execution paths, identify bottlenecks, and analyze downstream dependencies.
- Create actionable CloudWatch dashboards with key metrics: duration, error rate, throttles, and invocation count.
- Set up anomaly detection and dynamic thresholds for error rates and latency to reduce false positives.
- Correlate Lambda errors with upstream event sources (e.g., SQS dead-letter queue accumulation).
- Use CloudWatch Logs Insights to query and analyze logs across multiple functions and environments.
- Implement synthetic monitoring to validate end-to-end function behavior and SLA compliance.
- Define operational runbooks for common failure modes: throttling, timeouts, and permission errors.
Module 7: Governance and Compliance in Serverless Environments
- Define organizational standards for Lambda function naming, tagging, and metadata to enable governance at scale.
- Enforce configuration policies using AWS Config rules for function settings (timeout, memory, concurrency).
- Implement automated remediation for non-compliant functions using Lambda auto-remediation rules.
- Manage regulatory compliance by ensuring audit trails for function code changes and invocation history.
- Control deployment access through IAM policies and integration with enterprise identity providers.
- Document data flow and retention policies for Lambda-processed data to meet privacy regulations (GDPR, CCPA).
- Conduct periodic security reviews of third-party dependencies in deployment packages.
- Establish incident response procedures specific to serverless architectures, including rollback and containment.
Module 8: Scaling and High Availability Design
- Design for regional resilience by deploying Lambda functions across multiple AWS regions with active-passive or active-active patterns.
- Monitor and request concurrency limits increases based on traffic projections and business growth.
- Implement circuit breakers and bulkheads in function logic to prevent cascading failures under load.
- Use reserved concurrency to isolate critical functions from noisy neighbors in shared accounts.
- Optimize Kinesis or SQS event source scaling by aligning Lambda concurrency with stream shard count or queue depth.
- Handle throttling events by implementing exponential backoff, DLQs, and alerting on throttled invocations.
- Test autoscaling behavior under load using synthetic traffic and identify bottlenecks in downstream services.
- Design retry and fallback mechanisms for failed external API calls within function execution windows.
Module 9: Advanced Patterns and Hybrid Architectures
- Integrate Lambda with on-premises systems using AWS Systems Manager or hybrid event brokers (e.g., MQ).
- Implement long-running workflows by breaking them into chained Lambda functions with state storage.
- Use Lambda with EFS for access to shared, persistent file systems when local storage is insufficient.
- Process streaming data with Kinesis Data Analytics or Lambda, evaluating trade-offs in processing window and latency.
- Build real-time data pipelines from Lambda to S3, Redshift, or OpenSearch with batching and error handling.
- Containerize Lambda functions for larger dependencies, managing image size and build complexity.
