A company has application services that have been containerized and deployed on multiple Amazon EC2 instances with public IPs. An Apache Kafka cluster has been deployed to the EC2 instances.

What changes to the current architecture will reduce operational overhead and support the product release?

A. Create an EC2 Auto Scaling group behind an Application Load Balancer. Create additional read replicas for the DB instance. Create Amazon Kinesis data streams and configure the application services to use the data streams. Store and serve static content directly from Amazon S3.
B. Create an EC2 Auto Scaling group behind an Application Load Balancer. Deploy the DB instance in Multi-AZ mode and enable storage auto scaling. Create Amazon Kinesis data streams and configure the application services to use the data streams. Store and serve static content directly from Amazon S3.
C. Deploy the application on a Kubernetes cluster created on the EC2 instances behind an Application Load Balancer. Deploy the DB instance in Multi-AZ mode and enable storage auto scaling. Create an Amazon Managed Streaming for Apache Kafka cluster and configure the application services to use the cluster. Store static content in Amazon S3 behind an Amazon CloudFront distribution.
D. Deploy the application on Amazon Elastic Kubernetes Service (Amazon EKS) with AWS Fargate and enable auto scaling behind an Application Load Balancer. Create additional read replicas for the DB instance. Create an Amazon Managed Streaming for Apache Kafka cluster and configure the application services to use the cluster. Store static content in Amazon S3 behind an Amazon CloudFront distribution.

For those that don't know if answer is C or D. They say they want to support the increase demand... MultiAZ doesn't help with that, MuliAZ it's meant for HA, but read replicas are meant for increased demand... that's why ans is D

Also C doesnt handle scaling on the containers. Best to go with Fargate

Ans D. Solution is here. https://aws.amazon.com/blogs/big-data/power-your-kafka-streams-application-with-amazon-msk-and-aws-fargate/ Fargate+Amazon MSK A. Running container on EC2 is more expensive compared to Fargate B. Same as above + higher Multi AZ costs. C. same as B.

I would vote for C. RDS support auto-scaling -> less operating cost https://aws.amazon.com/about-aws/whats-new/2019/06/rds-storage-auto-scaling/#:~:text=RDS%20Storage%20Auto%20Scaling%20continuously,in%20the%20AWS%20Management%20Console. RDS-Multi-AZ- To support sync R/W in case of failures since more write load for DB with new orders

AWS Fargate with Amazon EKS is available in all Amazon EKS Regions except AWS GovCloud (US-East) and AWS GovCloud (US-West). from https://docs.aws.amazon.com/eks/latest/userguide/fargate.html

Cannot be D, as Fargate is part of ECS and not EKS B - looks correct 1, Cost saving with ASG 2. Storage Auto Scaling for Volume 3, Multi AZ for better support /availability
