A developer is preparing an automated script to launch multiple instances. Each instance type needs ephemeral storage volumes set up. The developer wants a method to group the repeated storage logic into a single, maintainable code segment. What coding practice is most useful?
Replicate the same snippet throughout the script wherever ephemeral volumes are configured
Define a single code block that is invoked multiple times for various instance types
Use environment variables in each location to hold ephemeral storage details
Refactor each instance type into a separate script containing ephemeral volume parameters
Creating a reusable code block that accepts parameters and sets up storage for each instance is the best approach. Grouping shared logic together in one place enhances readability and simplifies updates. An environment variable or replicated snippet strategy can increase duplication errors. Writing multiple scripts for each instance type is not efficient, as it results in additional overhead and more places to maintain the same logic.
