Some Basic Terminologies

In this episode, I will hold your hand and walk you through some basic cloud terminologies.
As a beginner, you need to get familiar with certain slang terms, and as your big sister, I am here to help you so let's dive in.

1. Bandwidth: This refers to the maximum amount of data that can be transferred over a network in a given amount of time. It is measured by bits per second (bps), kilobits (kbps), megabits per second (mbps), or gigabits per second (gbps). Higher bandwidth allows faster data transfer rates.

1. Latency: This refers to the time it takes for a data packet to travel from its source to its destination. It is measured in milliseconds (ms). Lower latency means less delay in data transmission.

1. Data center: A data center is a building, or a dedicated space within a building or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. It contains the computing infrastructure that IT systems require, such as servers, data storage drives, and network equipment. It is the physical facility that stores a company's digital data.

1. On-prem: This is when we managed our resources ourselves e.g content, access policy, usage, web application security, identity, operations, access and authentication, network security, Guest Os, data and content, audit logging, network, storage and encryption, hardened kernel and IPC, boot, and hardware.

2. IAAS: Infrastructure as a service provides virtualized computing resources such as servers, storage, and networking. Users have full control over the infrastructure and can configure it to meet their needs. Examples are AWS, Microsoft Azure, and GCP.

3. PAAS: Platform as a service provides a complete platform for developing, running, and managing applications including tools, libraries, and infrastructure. Users focus on developing and deploying applications, while the providers manage the underlying infrastructure. Examples are Heroku, Google App Engine, and Microsoft Azure App Service.

4. SAAS: Software as a service provides software applications over the Internet, eliminating the need for local installation and maintenance. Users access the application through a web browser or mobile app, and the provider manages the underlying infrastructure and maintenance. Examples are Salesforce, Dropbox, and Microsoft Office 365.

5. Zone: A zone is a deployment area within a region

6. Region: Region is a geographical area where instances are mapped for deploying a data center.

7. Point of Presence (POPs): This consists of a point of presence and edge locations that cache frequently accessed content and use advanced technologies like CDNs and routing optimization to efficiently and reliably deliver content and services to users.
