Cloud computing issues

<a href="/facts/Cloud_computing/guhg0FGV">Cloud computing</a> enables users to access scalable and on-demand computing resources via the internet, utilizing hardware and software virtualization. It is a rapidly evolving technology capable of delivering extensible services efficiently, supporting a wide range of applications from personal storage solutions to enterprise-level systems. Despite its advantages, cloud computing also faces several challenges. Privacy concerns remain a primary issue, as users often lose direct control over their data once it is stored on servers owned and managed by cloud providers. This loss of control can create uncertainties regarding data privacy, unauthorized access, and compliance with regional regulations such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), and the California Consumer Privacy Act (CCPA). Service agreements and shared responsibility models define the boundaries of control and accountability between the cloud provider and the customer, but misunderstandings or mismanagement in these areas can still result in security breaches or accidental data loss. Cloud providers offer tools, such as AWS Artifact (compliance documentation and audits), Azure Compliance Manager (compliance assessments and risk analysis), and Google Assured Workloads (region-specific data compliance), to assist customers in managing compliance requirements. 
Security issues in cloud computing are generally categorized into two broad groups. The first involves risks faced by cloud service providers, including vulnerabilities in their infrastructure, software, or third-party dependencies. The second includes risks faced by cloud customers, such as misconfigurations, inadequate access controls, and accidental data exposure. These risks are often amplified by human error or a lack of understanding of the shared responsibility model. Security responsibilities also vary depending on the service model—whether Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). In general, cloud providers are responsible for hardware security, physical infrastructure, and software updates, while customers are responsible for data encryption, identity and access management (IAM), and application-level security. 
Another significant concern is uncertainty regarding guaranteed Quality of Service (QoS), particularly in multi-tenant environments where resources are shared among customers. Major cloud providers address these concerns through Service Level Agreements (SLAs), which define performance and uptime guarantees and often offer compensation in the form of service credits when guarantees are unmet. Automated management and remediation processes, supported by tools such as AWS CloudWatch, Azure Monitor, and Google Cloud Operations Suite, help detect and respond to large-scale failures. Despite these tools, managing QoS in highly distributed and multi-tenant systems remains complex. For latency-sensitive workloads, cloud providers have introduced edge computing solutions, such as AWS Wavelength, Azure Edge Zones, and Google Distributed Cloud Edge, to minimize latency by processing data closer to the end-user. 
Jurisdictional and regulatory requirements regarding data residency and sovereignty introduce further complexity. Data stored in one region may fall under the legal jurisdiction of that region, creating potential conflicts for organizations operating across multiple geographies. Major cloud providers, such as AWS, Microsoft Azure, and Google Cloud, address these concerns by offering region-specific data centers and compliance management tools designed to align with regional regulations and legal frameworks.
