Your Development team wants to start making use of EC2 Instances to host their Application and Web servers. In the space of automation, they want the Instances to always download the latest version of the Web and Application servers when they are launched. As an architect, what would you recommend for this scenario?

B. Ask the Development team to create scripts which can be added to the Meta Data section when the instance is launched.
C. Use Auto Scaling Groups to install the Web and Application servers when the instances are launched.
D. Use EC2 Config to install the Web and Application servers when the instances are launched.
Explanation:
Answer – A
AWS Documentation mentions the following:
When you launch an instance in Amazon EC2, you have the option of passing user data to the instance that can be used to perform common automated configuration tasks and even run scripts after the instance starts. You can pass two types of user data to Amazon EC2: shell scripts and cloud-init directives. You can also pass this data into the launch wizard as plain text, as a file (this is useful for launching instances using the command line tools), or as base64-encoded text (for API calls).
