Study Notes

VPN (Virtual Private Network)

VPNs encrypt data during transmission, rendering it unreadable to potential interceptors, thereby protecting confidentiality.
Example usage includes accessing a company's internal resources via public Wi-Fi with encryption.
Protects data privacy on unsecured networks, such as those in coffee shops and airports.

Remote Access

VPNs allow secure access to an organization’s network from distant locations, benefiting remote workers and travelers.
An example is an employee retrieving files from their office network remotely via VPN.
Facilitates remote work by granting secure access to corporate resources.

IP Address Masking

VPNs obscure a user's real IP address, assigning a new one based on the VPN server's location, enhancing user anonymity.
Example: Browsing the web with an IP address from a different country complicates tracking.
Improves online privacy and aids in bypassing geographic content restrictions.

Secure Communication

VPNs ensure secure transmission of all data between users and the VPN server, protecting against data theft and eavesdropping.
Example: Businesses utilize VPNs to share sensitive information amongst various offices securely.
Essential for safeguarding business communications and data transfers online.

Access Control

VPNs implement access control measures to restrict who can connect and which resources they can access based on authentication.
Example: Companies may require VPN authentication before employees can access sensitive applications.
Aids in monitoring and managing access to company networks and resources.

Google BigQuery

A fully managed data warehouse for conducting large-scale data analyses, simplifying complex data operations.

IBM Cloud

Offers diverse cloud services, including IaaS, PaaS, and SaaS, focused on hybrid cloud solutions and enterprise-grade offerings.
Example services: IBM Cloud Virtual Servers for scalable computing and Kubernetes Service for managed containers.

Oracle Cloud

Provides a wide range of cloud services encompassing IaaS, PaaS, and SaaS, noted for robust database solutions.
Example services: High-performance Oracle Cloud Infrastructure and the self-managing Oracle Autonomous Database.

Alibaba Cloud

Significant cloud provider in Asia-Pacific, offering extensive services like computing, storage, and big data solutions.
Example services: Elastic Compute Service for scalable servers and ApsaraDB for managed database solutions.

Salesforce

Dominant provider of cloud-based CRM solutions, emphasizing customer relationship management and enterprise applications.
Example services: Salesforce Sales Cloud for sales management and Marketing Cloud for digital marketing efforts.

Private Cloud

Exclusively utilized by a single organization; can be hosted on-site or by third-party providers, allowing for higher control and customization than public clouds.
Example technologies: VMware vSphere for creating private cloud environments and Microsoft Azure Stack for extending Azure services on-premises.
Use Cases: Ideal for regulated industries (like finance and healthcare) and large enterprises with complex IT needs.

Hybrid Cloud

Integrates public and private clouds, enabling data and application sharing for enhanced flexibility and optimized infrastructure.
Example solutions: Microsoft Azure Hybrid for seamless integration and AWS Outposts for extending AWS to on-premises setups.
Use Cases: Suitable for dynamic workloads and disaster recovery solutions by replicating data across cloud environments.

Community Cloud

A collaborative cloud environment shared by multiple organizations with similar computing objectives or compliance needs.
Managed by the organizations or by third-party providers to accommodate shared requirements.
