Cloud computing provides businesses significant benefits such as potential cost savings, ease of sharing data and applications, automatic backups, and improved efficiencies. It allows scalable access to computing resources and storage over the internet. While security and reliability issues exist if providers experience outages, many businesses can benefit from cloud computing. Large multinational corporations and internet companies dealing with large amounts of data and users around the world are most likely to benefit from the scalability and accessibility of cloud resources. Both Amazon and subscribers must consider concepts like capacity planning, scalability, and total cost of ownership when using cloud computing services.
