You are the IT administrator for your company. You have the responsibility of creating the development environment for a LAMP stack. The requirement is that the development team always gets the latest version of the LAMP stack each time a new instance is launched. Which of the following is an efficient and effective way to implement this requirement? Choose 2 answers from the options given below.

Answer options:

A.Create an AMI with all the artifacts of the LAMP stack and provide an instance to the development team based on the AMI.
B.Create a CloudFormation template and use the cloud-init directives to download and install the LAMP stack packages.
C.Use the User data section and use a custom script that will be used to download the necessary LAMP stack packages.
D.Create an EBS Volume with the LAMP stack and attach it to an instance whenever it is required.

Answer – B and C
Using User data and cloud-init directives, you can always ensure you download the latest version of the LAMP stack and give it to the development teams. With AMI’s you will always have the same version and will need to create an AMI every time the version of the LAMP stack changes.
Option A is not an efficient way if compared with options B and
C.The AWS Documentation mentions
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).
