AWS Lambda and Serverless Development

AWS Lambda is an important service for modern application development. It allows developers to run code without managing traditional servers.

With serverless architectures, applications can respond to events and execute functions when required. This can be useful for APIs, data processing, automation, file processing, and backend applications.

Serverless development can help reduce infrastructure management and support automatic scaling. Developers need to understand how Lambda functions interact with other AWS services and how execution limits, permissions, monitoring, and performance affect applications.

Amazon S3 and Application Storage

Amazon S3 is widely used by applications for storing objects such as images, documents, backups, videos, logs, and other files.

Developers need to understand how applications interact with S3 using APIs and SDKs. They should also understand permissions, access policies, encryption, storage classes, and lifecycle management.

Properly designed S3 solutions can provide scalable and durable storage while supporting different application requirements.

Database Development on AWS

Applications often require databases for storing structured and unstructured information. AWS provides multiple database technologies for different workloads.

Amazon RDS supports managed relational databases, while Amazon DynamoDB provides a managed NoSQL database service.

Developers need to understand how to choose and use database technologies based on application requirements. Factors such as data structure, performance, scalability, consistency, and access patterns should be considered.
