This new article revisits a conceptual framework of cloud computing I introduced in 2009, exploring how cloud roles, billing models, and security have evolved over the past 15 years. It discusses the maturity of cloud services, the expansion of “as-a-service” models, and the rise of country-specific cloud solutions. The piece also highlights potential disadvantages such as hidden costs, vendor lock-in, and the recent trend of companies moving away from cloud providers. The article concludes with predictions of cloud computing.
