An events company runs a ticketing platform on AWS.The company’s customers configure and schedule their events on the platform.The events result in large increases of traffic to the platform.The company knows the date and time of each customer’s events.The company runs the platform on an Amazon Elastic Container Service (Amazon ECS) cluster.The ECS cluster consists of Amazon EC2 On-Demand Instances that are in an Auto Scaling group.The Auto Scaling group uses a predictive scaling policy.The ECS cluster makes frequent requests to an Amazon S3 bucket to download ticket assets.The ECS cluster and the S3 bucket are in the same AWS Region and the same AWS account.Traffic between the ECS cluster and the S3 bucket flows across a NAT gateway.The company needs to optimize the cost of the platform without decreasing the platform’s availability.Which combination of steps will meet these requirements?

A company is running a large containerized workload in the AWS Cloud.The workload consists of approximately 100 different services.The company uses Amazon Elastic Container Service (Amazon ECS) to orchestrate the workload.Recently the company’s development team started using AWS Fargate instead of Amazon EC2 instances in the ECS cluster.In the past, the workload has come close to running the maximum number of EC2 instances that are available in the account.The company is worried that the workload could reach the maximum number of ECS tasks that are allowed.A solutions architect must implement a solution that will notify the development team when Fargate reaches 80% of the maximum number of tasks.What should the solutions architect do to meet this requirement?Read More →

A large company is migrating its on-premises applications to the AWS Cloud.All the company’s AWS accounts belong to an organization in AWS Organizations.Each application is deployed into its own VPC in separate AWS accounts.The company decides to start the migration process by migrating the front-end web services while keeping the databases on premises.The databases are configured with local domain names that are specific to the on-premises environment.The local domain names must be resolvable from the migrated web services.Which solution will meet these requirements with the LEAST operational overhead?Read More →
