Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 277 discussion

A&D. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/Welcome.html 1. Relational database: RDS 2. Container-based applications: ECS "Amazon ECS enables you to launch and stop your container-based applications by using simple API calls. You can also retrieve the state of your cluster from a centralized service and have access to many familiar Amazon EC2 features." 3. Little manual intervention: Fargate You can run your tasks and services on a serverless infrastructure that is managed by AWS Fargate. Alternatively, for more control over your infrastructure, you can run your tasks and services on a cluster of Amazon EC2 instances that you manage.

why not B instead of A as you can promote a read replica to a standalone instance as a disaster recovery solution if the primary DB instance fails.

A.(O) multi-az <= 'little intervention' B.(X) read replica <= Promoting a read replica to be a standalone DB instance You can promote a read replica into a standalone DB instance. When you promote a read replica, the DB instance is rebooted before it becomes available. https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ReadRepl.html C.(X) use Amazon ECS instead of EC2-based docker for little human intervention D.(O) Amazon ECS on AWS Fargate : AWS Fargate is a technology that you can use with Amazon ECS to run containers without having to manage servers or clusters of Amazon EC2 instances. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/AWS_Fargate.html E.(X) EC2 launch type The EC2 launch type can be used to run your containerized applications on Amazon EC2 instances that you register to your Amazon ECS cluster and manage yourself. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/launch_types.html

Does "Higly Accesible" means the same than "Highly Available"? Multi-AZ does not provide scaling read capabilities for the standby node, while we can use read replicas for scaling reads.

Fargate:- • Launch Docker containers on AWS • You do not provision the infrastructure (no EC2 instances to manage) – simpler! • Serverless offering • AWS just runs containers for you based on the CPU / RAM you need

AD for sure

A over B for sure For ECS, use Fargate so D https://aws.amazon.com/fargate/?whats-new-cards.sort-by=item.additionalFields.postDateTime&whats-new-cards.sort-order=desc&fargate-blogs.sort-by=item.additionalFields.createdDate&fargate-blogs.sort-order=desc: "AWS Fargate is a serverless compute engine for containers that works with both Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS). "

A is obvious. D. Fargate is server less and use case is for containers. ECS and EKS.

Ans= A. Create an Amazon RDS DB instance in Multi-AZ mode. D. Create an Amazon Elastic Container Service (Amazon ECS) cluster with a Fargate launch type to handle the dynamic application load.

AD is correct

AD is ok

A, D is the correct answer.

A,D 1. Highly available solution: Amazon RDS DB instance in Multi-AZ mode 2. "as little manual intervention as possible": ECS cluster with a Fargate launch type

A& D because read replica for performance
