Study Notes

What is Cloud Computing?

Cloud computing is a subscription-based service that provides networked storage space and computer resources.
Users can access cloud resources through an internet connection, similar to accessing email through an email client.
Data in the cloud is stored remotely and can be accessed from any device with internet access.

Types of Clouds

Public Cloud: Accessible to anyone with an internet connection and access to the cloud space.
Private Cloud: Established for a specific group or organization with restricted access.
Community Cloud: Shared among two or more organizations with similar cloud requirements.
Hybrid Cloud: Combination of at least two different cloud types, such as public, private, or community.

Cloud Service Providers

Software as a Service (SaaS): Provides access to both resources and applications, eliminating the need for physical software installations.
Platform as a Service (PaaS): Offers components for developing and operating applications over the internet.
Infrastructure as a Service (IaaS): Focuses on computational infrastructure, outsourcing storage and resources like hardware and software.

Security Considerations

Cloud providers implement various security measures, such as encryption and data backups.
Users should inquire about the provider's security practices, encryption methods, hardware protection, backup procedures, and firewall configurations.
Third-party access to data remains a potential concern when utilizing cloud services.

Key Advantages of Cloud Computing:

Increased accessibility to information from any device with internet access.
Cost-effective solution for businesses by eliminating the need for on-site hardware and software investments.
Flexibility to scale storage space and resources as business needs change.

Key Disadvantages of Cloud Computing:

Potential security risks related to data storage and access.
Dependence on internet connectivity to access information.
Limited control over data storage and security compared to traditional computer setups.
