The cloud is known as the servers that are accessed over the web, and therefore database and software run on those servers. Cloud servers are spread in the data centers located across the world. By using cloud computing, candidates and organization don’t have to operate physical servers by their own or deploy software applications on their own machines.

For instance, you want to use a service which is not at your location so you can use it via cloud from other destination too. Cloud is like a remote data center which are present almost everywhere in the world from which you try to access the services such as servers' compute, storage etc. 

The best example to understand cloud is we humans live on earth or land, we need water, air and shelter to live. We get water through the process of water cycle. You don’t need to go in the sky to get water. It comes itself through the process being far away from the destination. Similar is the function of cloud, it serves you from different location, but you still get services at your own destination.

Here are some key aspects and benefits of cloud computing:

Scalability: Cloud services can scale resources up or down based on demand, allowing businesses to quickly adjust to changing needs without significant upfront investments.

Flexibility: Users can access cloud services from anywhere with an internet connection, using a variety of devices, enabling remote work and collaboration.

Cost-efficiency:  Organization find it very cost efficient when they pay only for what they consume called a pay-as-you-go model. It eliminates the need for upfront hardware purchases, maintenance, and infrastructure management costs.

Reliability and Availability: Cloud service providers often operate in multiple data centers worldwide, ensuring high availability and redundancy. They offer robust backup and disaster recovery solutions to protect data and minimize downtime.

Innovation and Agility: Cloud providers regularly introduce new services and features, empowering businesses to adopt cutting-edge technologies and accelerate their innovation cycles.

The following are the major cloud Service Providers:

Amazon Web Services (AWS)

Microsoft Azure

Google Cloud Platform (GCP)

IBM Cloud

Oracle Cloud

There are many other cloud providers available in the market such as Digital Ocean, Cisco Cloud etc. Here we will explore more on the top 3 cloud providers which are Amazon AWS, Microsoft Azure and Google GCP.
