AWS Application Development & DevOps

Question 1

Which AWS service is primarily used for automating application deployments?

Accepted Answer

AWS CodeDeploy

Answer

AWS CodeDeploy is a service that automates code deployments to any instance, including Amazon EC2 instances, on-premises servers, or serverless Lambda functions. It makes it easier to rapidly release new features, helps avoid downtime during application deployment, and handles the complexity of updating applications. CodeDeploy ensures consistent and reliable deployments.

Question 2

Which AWS service provides continuous integration and continuous delivery (CI/CD)?

Accepted Answer

AWS CodePipeline

Answer

AWS CodePipeline is a fully managed continuous delivery service that automates the release pipelines for rapid and reliable application and infrastructure updates. It orchestrates the entire CI/CD process, from source code commit through build, test, and deployment stages. This automation helps developers deliver features faster and more reliably.

Question 3

What is the purpose of AWS Lambda in application development?

Accepted Answer

Execute code without managing servers

Answer

AWS Lambda is a serverless compute service that allows developers to run code without provisioning or managing servers. Users simply upload their code, and Lambda automatically handles the underlying infrastructure, scaling, and maintenance. This enables developers to focus solely on writing code, significantly reducing operational overhead and costs.

Question 4

Which AWS service is used to manage containerized applications?

Accepted Answer

Amazon ECS

Answer

Amazon Elastic Container Service (ECS) is a highly scalable, high-performance container orchestration service that supports Docker containers. It allows users to easily run, stop, and manage Docker containers on a cluster of Amazon EC2 instances. ECS simplifies the deployment, management, and scaling of containerized applications.

Question 5

What is Infrastructure as Code (IaC) in DevOps?

Accepted Answer

Managing infrastructure through code

Answer

Infrastructure as Code (IaC) in DevOps is the practice of managing and provisioning infrastructure through machine-readable definition files, rather than manual hardware configuration or interactive configuration tools. This approach allows infrastructure to be treated like software, enabling version control, automation, and consistent, repeatable deployments across environments. It significantly reduces errors and improves efficiency.
