Chapter 6: Introduction to Computers and Information Technology, Preparing for IC3 Certification.

A computer is an electronic device for receiving, storing, processing, and outputting data using programs.

Cloud computing enables users and businesses to store and process their data in third-party data centers.
It provides advantages such as cost reduction, scalability, flexibility, and accessibility

Cloud computing is a cornerstone in the digital transformation of businesses, allowing a shift from traditional on-premise IT.
It enables more flexible, scalable, and cost-effective cloud-based solutions.
It is scalable, meaning companies can easily adjust resources based on demand, which ensures efficiency without excessive hardware investments.
It reduces the financial burden of purchasing, maintaining, and upgrading physical IT infrastructure.

Infrastructure as a Service (IaaS): Provides virtualized physical computing resources over the internet.
Platform as a Service (PaaS): Offers a platform for developing, running and managing applications without infrastructure management complexity.
Software as a Service (SaaS): Delivers software applications via the internet on a subscription basis.

Public Cloud: Computing resources owned and operated by a third-party provider, available to the general public or industry groups; pay-per-use.
Private Cloud: Computing resources used exclusively by a single business or organization, hosted on the organization's premises or by a third-party.
Community Cloud: Shared among several organizations within a specific community with common concerns, managed internally or by a third party.
Hybrid Cloud: Combines public and private clouds to enable data and application sharing, offering flexibility and cost adjustments for workload modifications.

Public Cloud: Cost-effective, scalable and flexible, and no maintenance.
Private Cloud: Enhanced security and control, customization, high investment.
Community Cloud: Shared costs, suitable for collaborative organizations, balance security and compliance needs.
Hybrid Cloud: Flexibility and scalability for high-volume operations, a balance between cost and control.

Resource Location: Traditional computing relies on on-premises resources, while cloud computing utilizes remote servers in data centers.
Operational Costs: Traditional computing includes ongoing maintenance, upgrade, and power consumption costs. Cloud computing offers pay-as-you-go or subscription models to reduce these costs.
Scalability: Traditional scaling requires purchasing additional hardware. Cloud computing enables on-demand resource adjustment.
Maintenance and Upgrades: Traditional computing requires dedicated IT staff for managing these tasks. Cloud providers maintain, upgrade, and manage services.
Accessibility and Collaboration: Traditional computing is limited to physical infrastructure locations, impacting collaboration, while cloud computing allows remote access.
Disaster Recovery and Data Backup: Traditional computing needs extensive setup and cost for disaster recovery, whereas cloud computing offers streamlined and cost-effective solutions as a service.
Security: Traditional computing requires in-house expertise and investment in security. Cloud computing offers sophisticated security measures handled by providers.

Virtualization plays a crucial role in cloud computing, enabling the creation of virtual resources like servers, storage, networking and computing infrastructures.
Types include Server, Storage, and Desktop Virtualization.
Core roles of virtualization in cloud computing include enhancing resource efficiency and utilization, allowing for scalability, reducing costs, better isolation, flexibility and speed, and promoting disaster recovery and backup.

The major cloud service providers include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), IBM Cloud, and Alibaba Cloud.
AWS is a pioneer and leader in the cloud computing market, launched in 2006.
Microsoft Azure launched in 2010 and excels in integration with Microsoft software.
Google Cloud Platform (GCP) was introduced in 2008 with the App Engine product, becoming fully supported in 2011.

Cloud storage offers remote storage and management for data.
SaaS delivers applications over the internet, avoiding installation and maintenance costs.

Cloud storage stores documents across multiple servers.
This offers advantages such as redundancy, security, and cost-effectiveness.
Cloud storage enables easy access to files from various devices and facilitates document sharing and collaborative work.
Cloud storage also automatically tracks revisions to allow reversion to previous versions.
