Study Notes

Cloud Computing Overview

Cloud computing allows users to access and use computing resources (e.g., servers, storage, databases) over the internet.
Cloud storage refers to saving data on remote servers, which can be accessed via the internet instead of being stored on local hard drives.

Infrastructure as Software

Infrastructure as Software (IaaS) enables users to provision and manage IT infrastructure components without needing physical hardware, offering virtual machines, storage, and networks.

Basic Cloud Service Models

Three primary cloud service models:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)

Advantages of Cloud Computing

Reduces capital expenditure by allowing companies to pay for services as needed (variable expense).
Provides scalability and flexibility to adjust resources based on demand.
Enhances collaboration and accessibility of applications from anywhere.
Addresses issues related to server capacity management, improving efficiency.

Challenges of Cloud Computing

Security concerns regarding data protection and privacy.
Reliability and potential service outages impacting access and performance.
Regulatory compliance challenges due to varying laws across regions.

Policy and Organizational Challenges

Organizational resistance to change due to traditional IT practices.
Governance issues related to data ownership and access control.

Technical Issues in Cloud Computing

Significant technical challenges include integration with on-premises systems.
Performance bottlenecks can occur if not properly managed.

Legal Issues

Licensing and intellectual property rights are significant legal challenges.
Jurisdictional issues may arise due to data hosted in different regions.

Cloud Service Providers

Amazon Web Services (AWS) has the most availability zones among cloud providers.
Microsoft Azure’s Intelligent Cloud segment focuses on providing cloud services and solutions for enterprise businesses.
Google Cloud Platform has the fewest regions available compared to other major providers.

Performance and Resource Management

Cloud service providers that excel in offering high availability often have more regions and availability zones.
IaaS provides the highest level of flexibility and control over IT resources.
PaaS allows organizations to focus primarily on application development rather than underlying infrastructure management.

Deployment Models

Fully cloud-based deployment utilizes resources entirely in the cloud.
Hybrid deployment connects cloud-based infrastructure with on-premises resources for optimal flexibility.

Cost Management Advantage

The advantage of converting capital expenses to operational expenses helps manage financial resources effectively.

SaaS and IaaS Descriptions

SaaS offers end-users applications accessed via the internet without local installation needs.
IaaS provides access to essential infrastructure components like virtual machines and storage.

Hybrid Deployment Connection

PaaS enables seamless integration of application development across both cloud and on-premises platforms.

On-Premises Deployment

While on-premises deployment lacks many cloud computing benefits, it still provides control over sensitive data and legacy systems.
