Cost analysis

From the perspective of cost, deploying services and applications in a cloud infrastructure such as AWS usually ends up being a lot cheaper than buying your own hardware. If you want to deploy your own hardware, you have to pay for all of the hardware mentioned previously (servers, network equipment, storage, and so on) upfront as well as licensed software, in some cases. In a cloud environment, you pay as you go. You can add or remove servers in no time, and will only be charged for the duration in which the servers were running. Also, if you take advantage of PaaS and SaaS applications, you will usually end up saving even more money by lowering your operating costs, as you won't need as many administrators to administrate your servers, database, storage, and so on. Most cloud providers (AWS included) also offer tiered pricing and volume discounts. As your service grows, you will end up paying less for each unit of storage, bandwidth, and so on.
