Now that you understand how it works, it’s easy to see that cloud computing has many advantages. And if the user ever needs an upgrade to accommodate more business, it’s as simple as signing a new rental agreement and exchanging the keys. The user gets to drive the vehicle, but it’s up to the owner to do repairs and routine maintenance, and to replace old cars with new ones when they age. In that way, cloud computing is like renting a car. That means they don’t have to buy software licenses, upgrade outdated servers, buy more machines when they run out of storage, or install software updates to keep pace with evolving security threats.
In exchange for a monthly fee, customers can access all the computing resources they need. That dramatically changes and simplifies the way businesses approach their IT resources.įor example, many cloud providers offer subscription-based services. They just focus on building great experiences for their customers, as opposed to the technical logistics. Companies that used to operate their own data centers no longer need to worry about provisioning, securing, scaling, maintaining, and upgrading infrastructure. It was expensive, impractical, and inefficient.īut that’s not necessary anymore. To appreciate it, consider how things worked before the cloud: Companies’ IT teams managed their own onsite data centers, which required regular hardware updates, outsized energy bills, and excessive amounts of real estate. The internet unites providers and users instantly across long distances.Īlthough the pieces are simple, the technology that puts them together is complex.Cloud service providers store data and applications on physical machines at locations known as data centers.
In a nutshell, cloud computing is a puzzle with three basic pieces:
