What is Cloud Computing?

Cloud computing is a technology model that delivers configurable computing resources—like servers, storage, databases, networking, software, and analytics—over the internet (“the cloud”). Instead of owning and maintaining physical hardware and software, users can rent or use these services from cloud providers like Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and others. 

These resources typically include servers, storage, databases, networking, software, and analytics. Users can scale these resources typically include servers, storage, databases, networking, software, and analytics. Users can scale these resources up or down as needed, paying only for what they use. This flexibility allows businesses and individuals to avoid large upfront investments in hardware and to quickly adapt to changing computing needs.

The benefits of cloud computing include cost efficiency, scalability, reliability, and global accessibility. It enables organizations to focus on their core business rather than managing complex IT infrastructure.

Understanding Cloud Computing in 2024

Cloud computing is like using someone else’s computer over the internet to do tasks, store data, or run applications, so you don’t need to own or manage the physical hardware yourself.

Example:

Imagine you want to store photos. Instead of saving them on your computer’s hard drive, you upload them to Google Drive. Google’s servers (the cloud) store your photos, and you can access them from any device with an internet connection. Similarly, services like Netflix stream movies and shows from the cloud, so you don’t need to download them onto your device.

Cloud computing offers several deployment models, including public cloud (shared resources available to multiple customers), private cloud (dedicated resources for a single organization), and hybrid cloud (a combination of public and private). It also provides various service models such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), each offering different levels of control and management for the user.
