Easily scale up and down
With cloud, a company can easily add resources as needed as they grow, without losing the quality of the service. At the same time, you can easily scale down again as the demand for resources decreases. This way, making sure that you don’t continue to pay for the resources you no longer need.
Another benefit is that you can also automatically expand memory, storage capacity, or processing power to a server based on the load of a service. There are two types of scaling: vertical and horizontal scaling.
When talking about vertical scaling, that includes upgrading a single resource such as installing more storage or memory capacity to a server. Horizontal scaling is about upgrading a system with additional resources or components. In horizontal scaling, you can add memory or processing power to a server by simply linking it with other servers.
The benefits of cloud scalability are also closely related to reliability and performance, as you reduce the likelihood of a service crashing or becoming unavailable when planning for, and using, the benefits of scalability.
