This IDC study forecasts revenue for 20 major categories of public IT cloud services, at the worldwide level and within eight geographic regions. At the heart of this forecast is our view of the cloud as the essential foundation for the emerging second chapter of the 3rd Platform era, centered on "multiplied innovation." This chapter — extending over the next five years — will see a dramatically accelerated period of cloud-native digital innovation, built around increasingly distributed and optimized cloud platforms and ecosystems and leveraging cloud-based AI, blockchain, and hyperagile application technologies such as containers, functions, microservices app architectures, and API-based integration.
According to IDC Chief Analyst Frank Gens, "In the next five years — what IDC calls the 'multiplied innovation' chapter of the 3rd Platform era — cloud adoption will surge as most developers leverage platforms and communities and use cloud-based AI, containers, functions, blockchain, and other key technologies to create and deploy as many applications on the cloud as prior generations deployed in the prior four decades. Enterprises that do not fully embrace the public cloud will be marginalized in this renaissance of digital innovation."
