Analysis of Cloud Service Providers and Computing Services in Modem IT Infrastructure

In recent years, a growth of cloud computing services has revolutionized modern IT infrastructure and left organizations with difficult choices of what service provider to use and how to implement such services. Much research is done on the level of individual cloud services, yet an important gap still exists with regard to comprehensive comparative analyses that evaluate major cloud service providers across multiple dimensions. This research systematically assesses market leaders: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP)—by taking into account their computing services, pricing models, metrics for performance, and security frameworks. Utilizing a mixed methods approach, we analyzed the available quantitative performance data of 2,500 cloud deployments across 12 regions from all over the world, in addition to carrying out qualitative assessments by structured interviews with 150 IT decision-makers. Our results have large differences in service reliability (±15%), cost-effectiveness (23% variance in similar workloads), and integration capabilities across providers. Of course, in compute-intensive workloads, AWS did better, but in integrating enterprises, Azure won, and in machine learning, one could see clear advantages with GCP. The study concludes that optimal cloud service selection is workload-specific rather than provider-centric, so that organizations can benefit from the multi-cloud strategy. Such insights define a decision frame for organizations that are using or planning to adopt cloud services, thereby contributing to the growing body of knowledge in cloud computing infrastructure management.
