You are migrating a legacy client-server application to AWS. The application responds to a specific DNS
domain (e.g. www.example.com) and has a 2-tier architecture, with multiple application servers and a database
server. Remote clients use TCP to connect to the application servers. The application servers need to know the
IP address of the clients in order to function properly and are currently taking that information from the TCP
socket. A Multi-AZ RDS MySQL instance will be used for the database.
During the migration you can change the application code, but you have to file a change request.

Your company produces customer commissioned one-of-a-kind skiing helmets combining nigh fashion with
custom technical enhancements Customers can show off their Individuality on the ski slopes and have access
to head-up-displays. GPS rear-view cams and any other technical innovation they wish to embed in the helmet.
The current manufacturing process is data rich and complex including assessments to ensure that the custom
electronics and materials used to assemble the helmets are to the highest standards Assessments are a
mixture of human and automated assessments you need to add a new set of assessment to model the failure
modes of the custom electronics using GPUs with CUDA, across a cluster of servers with low latency
networking.
What architecture would allow you to automate the existing process using a hybrid approach and ensure that
the architecture can support the evolution of processes over time?

Which of the following could be the root caused?

You have deployed a three-tier web application in a VPC with a CIDR block of 10.0.0.0/28. You initially deploy
two web servers, two application servers, two database servers and one NAT instance tor a total of seven EC2
instances. The web. Application and database servers are deployed across two availability zones (AZs). You
also deploy an ELB in front of the two web servers, and use Route53 for DNS Web (raffle gradually increases in
the first few days following the deployment, so you attempt to double the number of instances in each tier of the
application to handle the new load unfortunately some of these new instances fail to launch.

Your company hosts a social media website for storing and sharing documents. The web application allows
user to upload large files while resuming and pausing the upload as needed. Currently, files are uploaded to
your PHP front end backed by Elastic load Balancing and an autoscaling fleet of Amazon Elastic Compute
Cloud (EC2) instances that scale upon average of bytes received (NetworkIng). After a file has been uploaded,
it is copied to Amazon Simple Storage Service (S3). Amazon EC2 instances use an AWS Identity and Access
Management (IAM) role that allows Amazon S3 uploads. Over the last six months, your user base and scale
have increased significantly, forcing you to increase the Auto Scaling group’s Max parameter a few times. Your
CFO is concerned about rising costs and has asked you to adjust the architecture where needed to better
optimize costs.
