Sources: 7. Developments: 2. Enterprise cloud adoption is characterized by a tension between operational benefits and growing financial and security challenges. While cloud computing remains essential for digital business growth, providing flexibility and remote work support, organizations are encountering significant hurdles. Financial pressures are driving a trend toward cloud repatriation. Reports indicate that 29% of IaaS and PaaS spending is estimated to be wasted, and 62% of enterprises exceeded their cloud storage budgets last year due to unanticipated usage and egress fees. As a result, over 20% of workloads have been moved back to on-premise environments, a move also motivated by data sovereignty and regulatory compliance. Security remains a primary concern, identified by 82% of respondents as a top challenge. Key risks include protecting sensitive data from improper settings, managing access control for SaaS applications, and addressing configuration issues within cloud infrastructure. ## Timeline ### 2026-10-13: Cloud computing drives business growth while increasing security risks Cloud computing enables business flexibility and remote work but introduces critical security risks regarding data storage, application access control, and infrastructure configuration. 4 sources. https://clstr.news/cluster/cloud-computing-drives-business-growth-while-increasing-security-risks ### 2026-09-28: Enterprise cloud migration faces rising costs and repatriation trends Enterprises are increasingly repatriating workloads to on-premise systems due to rising cloud costs, wasted spending, and concerns regarding data sovereignty and security. 3 sources. https://clstr.news/cluster/enterprise-cloud-migration-faces-rising-costs-and-repatriation-trends --- Cite as: Enterprise cloud adoption and security challenges.
