Concepts
These services are commonly used in AWS cloud environments and understanding their features and use cases is essential for the AWS Certified Cloud Practitioner exam.
Amazon RDS:
Amazon RDS (Relational Database Service) is a managed database service that makes it easy to set up, operate, and scale a relational database in the cloud. It supports several database engines including MySQL, PostgreSQL, Oracle, SQL Server, and MariaDB.
Key features of Amazon RDS include automated backups, high availability with Multi-AZ deployments, automated minor version upgrades, and monitoring using Amazon CloudWatch. It also provides security features such as encryption at rest and in transit.
Amazon ECS:
Amazon ECS (Elastic Container Service) is a fully managed container orchestration service that allows you to run and scale containerized applications on AWS. With ECS, you can easily deploy and manage Docker containers without having to manage the underlying infrastructure.
Key features of Amazon ECS include support for both EC2 and Fargate launch types, integration with AWS IAM for fine-grained access control, auto scaling, and service discovery using AWS CloudMap.
Amazon EKS:
Amazon EKS (Elastic Kubernetes Service) is a managed Kubernetes service that allows you to run Kubernetes on AWS without having to install, operate, and maintain the Kubernetes control plane. With Amazon EKS, you can deploy, manage, and scale containerized applications using Kubernetes.
Key features of Amazon EKS include integration with AWS IAM for authentication and authorization, support for Kubernetes RBAC (Role-Based Access Control), native VPC networking, and seamless integration with other AWS services.
Amazon DynamoDB:
Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. It is designed to handle large volumes of data and high traffic applications.
Key features of Amazon DynamoDB include automatic scaling, fast and predictable performance, built-in security features such as encryption at rest and in transit, and seamless integration with other AWS services.
In summary, understanding the features and use cases of managed AWS services such as Amazon RDS, Amazon ECS, Amazon EKS, and Amazon DynamoDB is essential for the AWS Certified Cloud Practitioner exam. Make sure to familiarize yourself with these services and their key features to succeed in the exam.

Which service is best suited for running a highly available and scalable WordPress application?
- A) Amazon DynamoDB
- B) Amazon RDS
- C) Amazon EKS
- D) Amazon ECS
- Answer: B) Amazon RDS
WordPress uses a MySQL database to store its data, and Amazon RDS provides a scalable, managed relational database service that supports MySQL, making it well-suited to run WordPress.
True/False: Amazon ECS can only be used with AWS Fargate for serverless compute.
- Answer: False
Amazon ECS can be used both with AWS Fargate for serverless compute and with Amazon EC2 instances to provide greater control over the EC2 instances that host the containers.
True/False: Amazon EKS automatically scales the underlying infrastructure.
- Answer: False
While Amazon EKS manages the Kubernetes control plane, scaling the underlying infrastructure requires configuration of the Auto Scaling group properties or using a Kubernetes autoscaler.
Multiple Select: Which AWS services provide managed services for containers? (Select two answers)
- A) Amazon EKS
- B) Amazon RDS
- C) Amazon ECS
- D) Amazon S3
- Answer: A) Amazon EKS, C) Amazon ECS
Both Amazon EKS and Amazon ECS are managed services designed specifically for running containerized applications on AWS.
True/False: You need to manually perform software patching for the underlying EC2 instances when using AWS Fargate with Amazon ECS.
- Answer: False
AWS Fargate is a serverless compute engine for containers that works with Amazon ECS, eliminating the need to manage servers or clusters, including the manual patching of software on the underlying infrastructure.
