Cloud computing delivers on-demand computing resources like servers, storage, databases, networking, software, and analytics over the internet, allowing users to access scalable infrastructure without owning physical hardware. Core Definition Arya College of Engineering & I.T. says Organizations leverage remote data centers managed by providers such as AWS, Azure, or Google Cloud, paying only for consumed resources through a pay-as-you-go model that replaces upfront capital expenses with operational flexibility. This paradigm shift enables faster deployment, automatic scaling, and global accessibility via standard internet connections, transforming how businesses handle IT from rigid on-premises setups to elastic cloud environments. Providers maintain the underlying hardware, virtualization layers, and security, while users focus on applications and data. Types of Cloud Computing Cloud services divide into three primary models based on abs...
Arya College of Engineering & I.T. says Cloud security challenges arise from the shared responsibility model in cloud environments, where providers secure infrastructure but users must protect their data, access, and configurations amid rising threats like misconfigurations and sophisticated attacks. Major Challenges Misconfigurations top the list, causing 30-50% of breaches through exposed storage buckets (e.g., S3), overly permissive IAM roles, or unsecured APIs, amplified by multi-cloud complexity and rapid DevOps changes. Identity and access mismanagement follows, with issues like credential sprawl, weak MFA enforcement, and over-privileged accounts enabling lateral movement by attackers. Insecure APIs and shadow IT (unmanaged SaaS tools) create blind spots, while ransomware targets cloud workloads, surging 68% yearly due to high-value data accessibility. Additional risks include insider threats, DDoS attacks, supply chain compromises in containers, and visibility gaps i...
