Industry Classification for Technology Investments

A financial analyst is evaluating a new investment opportunity in the technology sector, specifically in companies involved in cloud computing and artificial intelligence. As part of the due diligence process, the analyst needs to determine the appropriate industry classification for these firms based on the Global Industry Classification Standard (GICS). GICS categorizes industries based on their business activities and similarities in economic characteristics.

The analyst identifies three potential classification options: 1) Software, 2) Information Technology Services, and 3) Communication Services. Each classification encompasses a range of companies that may overlap in their offerings but serve distinct customer needs and markets.

Which of the following classifications would be the most appropriate for firms primarily engaged in cloud computing and artificial intelligence?
