Amazon EC2 for Application Development

Amazon EC2 provides virtual computing capacity that developers can use to run applications and services. Developers may deploy web applications, APIs, backend services, and other workloads on EC2 instances.

Understanding EC2 includes learning about instance configuration, storage, security groups, networking, application deployment, and scalability.

Although managed and serverless services can reduce infrastructure management, EC2 remains important for workloads that require greater control over the underlying computing environment.

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.
