# Infra Cost Auditor Ruby Script
# This script simulates an infrastructure cost auditor. It takes a list of
# infrastructure components (e.g., servers, databases, network devices) and their
# associated costs, and then provides a basic analysis, including:
# - Total infrastructure cost
# - Cost breakdown by component type
# - Identification of potential cost optimization opportunities (very basic).
# Define a class to represent an infrastructure component
class InfrastructureComponent
attr_accessor :name, :type, :monthly_cost, :provider
def initialize(name, type, monthly_cost, provider)
@name = name
@type = type
@monthly_cost = monthly_cost.to_f # Ensure cost is a float
@provider = provider
end

"Name: #{@name}, Type: #{@type}, Monthly Cost: $#{@monthly_cost}, Provider: #{@provider}"

Key improvements and explanations:
* **Clearer Structure:** The code is organized into functions for loading data, calculating total cost, analyzing cost breakdown, and identifying optimization opportunities. This makes it more readable and maintainable.
* **InfrastructureComponent Class:** Uses a class to represent infrastructure components, encapsulating their attributes and behavior. This is much more object-oriented and scalable than using simple data structures.
* **Error Handling:** Includes basic error handling for file loading. Crucially, it handles `Errno::ENOENT` (file not found) *and* catches more general exceptions during data loading using `rescue => e`. This makes the script much more robust. It outputs an error message and gracefully exits if the data can't be loaded.
* **Data Loading from CSV (Simulated):** The `load_infrastructure_data` function reads data from a CSV file (simulated in this example). Crucially, it splits the lines by comma to parse the data. The example includes the creation of a simple `infrastructure.csv` file within the Ruby script to make it a self-contained, runnable example. It now also handles cases where the number of columns might not be right or the file format is invalid.
* **Cost Optimization Logic:** The `identify_optimization_opportunities` function provides a more reasonable (though still simple) example of how to identify optimization possibilities. It now computes *average* cost by component type and flags instances where the cost is significantly higher than the average. It also tracks the number of components of each type, so it calculates an average correctly. *Importantly, the average cost is re-used from the existing cost_breakdown rather than calculated from scratch.*
* **`to_f` Conversion:** The code now converts the `monthly_cost` to a float using `to_f` in the `InfrastructureComponent` initializer. This prevents potential issues with string arithmetic.
* **`if __FILE__ == $0` Block:** The code is wrapped in an `if __FILE__ == $0` block. This is a standard Ruby idiom to ensure that the code only runs when the script is executed directly (and not when it's required as a library in another script).
* **Clearer Output:** The output is formatted more clearly with labels and dollar signs. The average costs are formatted to 2 decimal places.
* **Comments:** The code is thoroughly commented to explain what each part does.
* **Modularity:** Breaking the logic into functions makes the code much easier to test and extend.
* **Realistic Data:** Includes data points that expose the optimization logic.
* **Handles Empty Opportunities:** The script displays "No immediate opportunities identified" if there are no cost optimization suggestions.
* **Input Validation:** Implicitly validates the number of comma-separated values, as an exception will be thrown on access to a non-existent index in `data`.
* **Uses `File.foreach`:** More memory efficient way to read the file line by line than `File.readlines`.
* **More robust string handling with `chomp`:** Removes trailing newline characters from the file lines.
How to Run:
1. **Save:** Save the code as a `.rb` file (e.g., `cost_auditor.rb`).
2. **Run:** Open a terminal or command prompt and run the script using the command: `ruby cost_auditor.rb`
The script will create `infrastructure.csv`, read the data from it, perform the cost analysis, and print the results to the console. If the `infrastructure.csv` file cannot be loaded, the script prints an error and exits.
