'Fault Tolerance' ensures that a cloud service remains operational despite server failures. This typically involves redundant systems or failover mechanisms to maintain service availability.

Google Cloud Storage Triggers (Notifications) can automatically trigger a function when objects are uploaded to a bucket, enabling immediate processing.

Amazon S3 (Simple Storage Service) is AWS's primary service for object storage. It provides scalable, durable, and highly available object storage in the cloud, commonly used for data and file storage.

Paravirtualization requires modifying the guest OS to improve performance, whereas full virtualization does not require such modifications.

Private Clouds are typically associated with higher upfront costs because organizations need to invest in their infrastructure and management. Public clouds share resources and costs with multiple organizations.

A hybrid cloud combines public and private cloud infrastructure, whereas a multi-cloud involves using services from different cloud providers, which may not be public-private mix.

The cloud infrastructure designed for use by the Public is accessible by individuals, businesses, and organizations. It is hosted and managed by a cloud service provider and offers services on a pay-as-you-go basis. Public clouds are shared resources, providing flexibility and cost-effectiveness.

Accessibility is a key aspect of cloud computing that ensures that resources are available from anywhere, on any device, making it suitable for global use.

To optimize cloud costs, the organization should focus on analyzing resource utilization and efficiency, identifying underused resources, and rightsizing.

This is a classic example of a phishing attack, where attackers deceive users into revealing their credentials, leading to unauthorized access and account hijacking.
