A company has hired you to assist with the migration of an interactive website that allows registered users to rate local restaurants. Updates to the ratings are displayed on the home page and ratings are updated in real time. Although the website is not very popular today, the company anticipates that it will grow over the next few weeks. They also want to ensure that the website to remain highly available. The current architecture consists of a single Windows server 2008R2 web server and a MySQL database on Linux. Both reside inside on an on-premise hypervisor. What would be the most efficient way to transfer the application to AWS, ensuring high performance and availability?
A. Launch one Windows Server 2008 R2 instance in us-west-1b and one in us-west-1a and configure auto-scaling. Copy the web files from on premises web server to each Amazon EC2 web server, using Amazon S3 as the repository. Launch a multi -AZ MySQL Amazon RDS instance in us-west-1a. Import the data into Amazon RDS from the latest MySQL backup. Create an elastic load balancer (ELB) to front your web servers. Use Route 53 and create an alias record pointing to the ELB.
B. Export web files to an Amazon 53 bucket in us-west-1. Run the website directly out of Amazon 53. Launch a multi-AZ MySQL Amazon RDS instance in us-west-1a. Import the data into Amazon RDS from the latest MySQL backup. Use Route 53 and create an alias record pointing to the elastic load balancer.
C. Use AWS VM Import/Export to create an Amazon EC2 AMI of the web server. Configure auto-scaling to launch one web server in us-west-1a and one in us-west-1b. Launch a multi-AZ MySQL Amazon RDS instance in us-west-1a. Import the data Into Amazon RDS from the latest MySQL backup. Create an elastic load balancer (ELB) in front of your web servers. Use Amazon Route 53 and create an A record pointing to the ELB.
D. Use AWS VM Import/Export to create an Amazon EC2 AMI of the web server. Configure auto-scaling to launch one web server in us-west-1a and one in us-west-1b. Launch a Multi-AZ MySQL Amazon RDS instance in us-west-1b. Import the data into Amazon RDS from the latest MySQL backup. Use Amazon Route 53 to create a hosted zone and point an A record to the elastic load balancer.
