A famous online travel company has hosted its application in a multi-tier architecture. The application is hosted in organization’s premises. The organization had faced a huge traffic request recently due to the sudden announcement on offers, which resulted in downtime. Your organization is likely to experience a similar burst due to the same offer announcement. Being part of administrator team, you are asked to improve the infrastructure rapidly such that it can handle the huge traffic request.

Your application architecture currently uses several Linux Apache web servers placed behind the load balancer and Linux based MYSQL Database server.

The organization has planned to leverage AWS services to handle the burst. Which of the below solutions from AWS will help in resolving the issue in less amount of time?

Create a static website in S3 bucket. Create a hosted zone in Route 53, opt for failover routing policy and map the S3 url to it.

Create an AMI, which can be used to launch web servers in EC2 and place them in-front of the Elastic Load Balancing. Ensure that the load balancers balance the traffic between on-premises server and AWS servers. Create Auto Scaling group, which uses the AMI to scale the web tier based on the incoming traffic.

Setup a CIoudFront distribution and configure CloudFront to cache objects from your on-premises environment using the custom origin option. Customize your object cache behavior and TTL so that the data will be present in the cache for the defined TTL.

Use VM Import/Export to quickly convert an on-premises web server to an AMI. Create Auto Scaling group, which uses the AMI to scale the web tier based on incoming traffic.
