Naomi wants to deploy a tool that can allow her to scale horizontally while also allowing her to patch systems without interfering with traffic to her web servers. What type of technology should she deploy?

Background: A startup company wants to host its Python and React-based application (Backend: Python API and Frontend React) using AWS. But they are not familiar with the AWS cloud platform. They want to ensure that the application is secure, scalable, highly available, and cost-efficient. As a solutions architect, you have to design a proper solution to meet their below requirements. Goal: To architect a solution that is secure, scalable, highly available, and cost-effective using AWS. Requirements: - They are concerned about the security of the application, so they have decided to isolate their network from the rest of the customers virtually. Set up a secure virtual network where only the frontend of the application is accessible by users and not the database. - Execute the React application code using AWS Elastic Beanstalk. Ensure that the source code of the web application is automatically picked, pushed to the master branch, and deployed on the servers. - Ensure all the UI images served to the frontend application code are provisioned via a secure storage unit. - There should be enough backups for both the web and database servers, so if the setup crashes, we can launch a new one from the disaster recovery backups. - They are uncertain about the traffic pattern, how low or high it can be, so they want the web application to be running on at least two EC2 instances all the time, and when there is a high load, they must burst up to four instances in total. - The web application should be highly available, even if any VM fails to respond to queries, there should be a mechanism to switch the connection to another healthy VM automatically. - Automate the download of all the activity logs into a CSV file, create a stream of data, analyze it, and display it via a dashboard. - The web application should also be cached globally, so users worldwide can access it with low latency.
