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.

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

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.

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

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

Microsoft Azure offers Azure SQL Database, a managed SQL database service that seamlessly integrates with Microsoft products, making it a natural fit.

Infrastructure as a Service (IaaS) provides users with virtualized infrastructure components. Organizations manage and configure the operating system, applications, and data on top of this infrastructure while leaving hardware management to the cloud provider.

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

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

In the "re-hosting" strategy, applications are migrated as-is to the cloud, with modifications planned for a later phase.

Customer Relationship Management (CRM) software primarily focuses on managing and improving interactions and relationships with customers.

Storage virtualization abstracts physical storage devices to create a logical pool, simplifying management and improving utilization.
