What is the cloud?

The cloud or cloud computing is a global network of distributed servers hosting software and infrastructure accessed over the internet. It enables organizations to operate efficiently without needing any extensive internal infrastructure. With the cloud, users and organizations can access the same files and applications from almost any device since the computing and storage take place on servers in a data center instead of locally on the user device or in-house servers.

For instance, users can access their Instagram account and emails with all their files and conversation history from a new device, all virtue of the cloud. As cloud vendors update and maintain the servers themselves, cloud computing is one of the most cost-efficient solutions for organizations, helping them save significantly on IT costs and overheads.

How does cloud computing work?

Cloud computing leverages virtualization technology that enables the creation of digital entities called virtual machines. These virtual machines emulate the behavior of physical computers, existing harmoniously on a shared host machine yet maintaining strict isolation from one another.

The virtual machines also efficiently use the hardware hosting them, giving a single server the ability to run many virtual servers. This transforms data centers into highly efficient hubs capable of serving multiple organizations concurrently at a remarkably economical cost. The efficiency also extends to the reliability of cloud services since cloud service providers back up their services on multiple machines across multiple regions to guarantee uninterrupted service delivery.

Navigating the cloud is a seamless experience for users, accomplished through the sophisticated gateways of browsers or applications, regardless of their device. Many elements work in tandem to ensure seamless cloud navigation experience for users. Here are some of the core components of the cloud that help it operate like well-oiled machinery.
