Benefits of Cloud Computing

Stop guessing capacity: Using cloud computing you can completely stop guessing the infrastructure capacity you need because you can add or remove your computing capacity whenever you need it. In the cloud, the capacity can scale up or down within a few minutes.

Increase speed and agility: In cloud computing, all the resources are just one click away. This reduces the time to make those resources available to your developers from weeks to just minutes. This results in a dramatic increase in agility for the organization since the cost and time it takes to experiment and develop are significantly lower.

Benefit from massive economies of scale: By using cloud computing, you can achieve a lower variable cost than you can get on your own. Because usage from hundreds of thousands of customers is aggregated in the cloud, providers such as AWS can achieve higher economies of scale, which translates into lower pay-as-you-go prices.

Stop spending money running and maintaining data centers: Cloud computing lets you focus on your own customers, rather than on the heavy lifting of racking, stacking, and powering servers.

Go global in minutes: You can deploy your application in multiple regions in the world within a few minutes.
