Study Notes

Cloud and Cloud Services

A cloud is a symbol used to represent complex network infrastructure that we don't want to or need to identify in detail.
It can include firewalls, internal networks, and external networks.

Cloud Services

Cloud services are services provided by someone else, implying that someone else is doing the heavy lifting.
A service provider provides an application that customers can use, and they manage the underlying infrastructure.
The service provider is responsible for the operating system, virtualization, servers, storage, and networking.

Types of Cloud Services

Software as a Service (SaaS): Customers use an application provided by the service provider, and the service provider manages everything else (e.g., Salesforce).
Infrastructure as a Service (IaaS): Customers rent virtual machines and infrastructure from the service provider, and they manage those virtual machines (e.g., renting servers).

Cloud Deployment Models

Public Cloud: Services are available to anyone, and anyone can use them.
Private Cloud: Services are restricted to a specific group or organization.
Community Cloud: Services are shared by multiple organizations with similar needs or interests.
Hybrid Cloud: A combination of public and private cloud services.

Automation and Provisioning

Automation is used to automate tasks and provisioning to speed up deployment.
Infrastructure as Code (IaC) allows for consistent results and reduces errors.
Automation enables self-service kiosks for customers to create their own virtual machines.

Connectivity and Security

Connectivity to cloud services depends on the type of service (e.g., browser for SaaS, VPN for IaaS).
Multitenancy allows multiple customers to share the same resources, but requires isolation and security controls to prevent interference.
Data storage location and security are critical concerns for customers.

Benefits of Cloud Services

Scalability and elasticity allow customers to grow or shrink their resources as needed.
Reduced management burden for customers, as the service provider handles infrastructure.
Automated provisioning and infrastructure management.
