Question: Can you explain the difference between Amazon Aurora and traditional relational database systems like MySQL or PostgreSQL?
|
Answer: Amazon Aurora is a fully managed relational database service that is compatible with MySQL and PostgreSQL,
offering greater scalability, performance, and availability compared to traditional relational database systems.
Aurora is designed to automatically scale storage capacity as needed, provide high availability with automatic failover,
and deliver fast read and write performance by replicating data across multiple availability zones.

Question: What is AWS ECS and how does it differ from AWS EKS?
|
Answer: AWS ECS (Elastic Container Service) is a fully managed container orchestration service that allows you to
run and scale Docker containers on EC2 instances.
AWS EKS (Elastic Kubernetes Service), on the other hand, is a fully managed Kubernetes service that enables you to run
Kubernetes clusters on AWS infrastructure. ECS provides native integration with AWS services,
while EKS offers compatibility with standard Kubernetes tooling and APIs.

Question: Can you explain the difference between AWS CloudFormation stack and template?
|
Answer: An AWS CloudFormation stack is a collection of AWS resources that are created and managed as a single unit.
And a CloudFormation template is a JSON or YAML file that defines the AWS resources, their configurations,
and relationships within the stack. The template serves as the blueprint for creating and updating stacks.

Question: What is AWS CodePipeline, and how does it facilitate CI/CD workflows?
|
Answer: AWS CodePipeline is a continuous integration and continuous delivery service that automates the build, test,
and deployment phases of your release process.
It allows one to define and model the entire workflow from source code repository to production deployment using a series of stages and actions.
CodePipeline integrates with other AWS services, such as AWS CodeBuild, AWS CodeDeploy, and AWS CodeCommit,
to enable end-to-end automation of your software release process.
