I will be AWS serverless apps and event driven architecture consultant

Serverless architecture on AWS means building applications without worrying about managing servers. It automatically scales, manages infrastructure, and you pay only for the compute time you use.

Event-Driven Architecture (EDA) enhances responsiveness and scalability. It allows systems to react to real-time events, making your applications more dynamic and adaptable to change.

Microservices architecture splits applications into smaller, independently deployable services, improving resilience, scalability, and enabling faster updates.

Continuous Integration/Continuous Deployment (CI/CD) automates the deployment process, allowing for quicker, more reliable application updates and releases.

Common services include AWS Lambda for computing, Amazon S3 for storage, Amazon API Gateway for APIs, DynamoDB for databases, SQS and SNS for messaging, and EventBridge for event buses.

With Serverless, you only pay for the compute time you consume, reducing the costs associated with idle server capacity and operational overhead.

AWS provides robust security measures at the service and infrastructure level. Implementing best practices in IAM, encryption, and data protection is crucial for securing your serverless applications.

State management can be achieved through services like Amazon DynamoDB for database needs, AWS Step Functions for workflow orchestration, and caching strategies to maintain application state.
