1.Basics of Cloud Computing

What is Cloud?

It's like having a powerful computer somewhere out there on the web that you can use for tasks without needing to own or physically manage the hardware. This allows users to access data and applications from anywhere with an internet connection.

In simpler terms, using someone else's server that is maintained by them, owned by them, but you can use it on the internet by paying for it like a service.

What is cloud computing?

Cloud computing is a technology model that involves the delivery of computing services over the internet. Instead of owning and maintaining physical servers and infrastructure, users can access and use

• computing resources,

• applications,

• storage

provided by either third-party service providers (public cloud) or their own organization (private cloud) through the internet. These services are hosted in data centers located around the world.

Public cloud:

Cloud services hosted for public use i.e. publicly available cloud services which anyone can use by buying a subscription.

Who Uses It: Everyone, like individuals, businesses, and organizations.

What It's Like: Imagine a giant, shared computer space on the internet. It's like using apps, storing files, or doing tasks on the internet that anyone can access.

Example: Think of Google Drive or Amazon Web Services (AWS).

Private cloud:

Cloud services hosted for an organization's personal use i.e. no one outside the organization can access these services.

Who Uses It: One specific organization or business.

What It's Like: Picture having your own personal, private computer space. It's like a digital clubhouse where only you and your team have access. Others can't just drop in.

Example: A company using its own server for all its digital needs.

Hybrid cloud:

When a company uses both public and private cloud.

Who Uses It: A mix of everyone, depending on needs.

What It's Like: It's like having your private computer space, but sometimes you use the shared internet space too.

Example: A business storing sensitive data in its private space but using the public cloud for extra storage or specific tasks.

In a Nutshell:

Public Cloud: Shared digital space for everyone.

Private Cloud: Your own exclusive digital space.

Hybrid Cloud: Using both your private space and the shared online space when needed.
