A company’s video streaming platform usage has increased from 10,000 users each day to 50,000 users each day in multiple countries.The company deploys the streaming platform on Amazon Elastic Kubernetes Service (Amazon EKS).The EKS workload scales up to thousands of nodes during peak viewing time.The company’s users report occurrences of unauthorized logins.Users also report sudden interruptions and logouts from the platform.The company wants additional security measures for the entire platform.The company also needs a summarized view of the resource behaviors and interactions across the company’s entire AWS environment.The summarized view must show login attempts, API calls, and network traffic.The solution must permit network traffic analysis while minimizing the overhead of managing logs.The solution must also quickly investigate any potential malicious behavior that is associated with the EKS workload.Which solution will meet these requirements?Read More →

A company is migrating its on-premises Windows applications and Linux applications to AWS.The company will use automation to launch Amazon EC2 instances to mirror the on-premises configurations.The migrated applications require access to shared storage that uses SMB for Windows and NFS for Linux.The company is also creating a pilot light disaster recovery (DR) environment in another AWS Region.The company will use automation to launch and configure the EC2 instances in the DR Region.The company needs to replicate the storage to the DR Region.Which storage solution will meet these requirements?Read More →

A company is running a custom-built application that processes records.All the components run on Amazon EC2 instances that run in an Auto Scaling group.Each record’s processing is a multistep sequential action that is compute-intensive.Each step is always completed in 5 minutes or less.A limitation of the current system is that if any steps fail, the application has to reprocess the record from the beginning.The company wants to update the architecture so that the application must reprocess only the failed steps.What is the MOST operationally efficient solution that meets these requirements?Read More →

A company is developing a web application’s infrastructure using AWS CloudFormation.The database engineering team maintains the database resources in a CloudFormation template, and the software development team maintains the web application resources in a separate CloudFormation template.As the scope of the application grows, the software development team needs to use resources maintained by the database engineering team.However, both teams have their own review and lifecycle management processes that they want to keep.Both teams also require resource-level change-set reviews.The software development team would like to deploy changes to this template using their CI/CD pipeline.Which solution will meet these requirements?Read More →
